Lawsuit against EPA over pesticide-coated seeds cites honeybee die-offs
re: neonicotinoid treated seeds
Lawsuit against EPA over pesticide-coated seeds cites honeybee die-offs
(By Sebastien Malo, Reuters, 15 December 2021)
'The Center for Food Safety and the Pesticide Action Network North America alleged in San Francisco federal court Tuesday that the EPA failed to register the seeds, widely used by crop farmers, as a pesticide under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Registration would require the seeds to conform to FIFRA labeling specifications, according to the lawsuit.
Coated seeds are typically treated with neonicotinoids. The class of insecticide disrupts the central nervous system of insects and predators of growing plants.'SNAP Comment: The situation seems the same in Canada. In Canada, under article 2.1 of the Regulatory Directive: Harmonization of Regulation of Pesticide Seed Treatment in Canada and the United States (11 April 2003): 'For the purposes of FIFRA, pesticide-treated seeds are considered to be pesticides themselves because they are a mixture of substances that are intended to prevent, destroy, repel or mitigate a pest. In 1988, the EPA promulgated regulation 40 Code of Federal Regulations (CFR) 152.25(a) exempting certain treated articles (including treated seeds) from regulation under FIFRA provided that both of the following conditions are met:
- the pesticide used for the treatment is registered for such use; and
- the treatment is for the protection of the article or substance itself.'

Review Shows that Monsanto/Bayer Claims of Glyphosate Safety Not Supported by Credible Science
Review Shows that Monsanto/Bayer Claims of Glyphosate Safety Not Supported by Credible Science
(Beyond Pesticides, December 21, 2021) 'A research team undertaking a review of industry-conducted glyphosate safety studies submitted to EU (European Union) regulators shows that most of the research fails to meet current international standards for scientific validity. The researchers find that of the 11 reviewed studies, which were submitted to regulators by Bayer AG (now owner of the Monsanto “Roundup” brand of glyphosate herbicide) and several other chemical companies, only two are scientifically “reliable”; six others are deemed “partly reliable,” and the remaining three, “not reliable.” ' The issue is that older studies rely on tests that are only 50% reliable for detecting cancer. 'In response to that July report, the former director of the U.S. National Institute for Environmental Health Sciences (NIEHS), Linda Birnbaum, PhD, indicated that the problem of regulators accepting industry studies “at industry’s word” and simultaneously “ignoring red flags raised in non–industry funded research” is ongoing, according to The Guardian.'

Disregarding the European Green Deal, Two Endocrine Disrupting Pesticides Reapproved: Will the Court of Justice Fix This?
flumioxazin and cypermethrin
(PAN Europe, November 10, 2021) EU Member States have voted last week for the re-approval of flumioxazin and cypermethrin, two endocrine disrupting and bee-toxic pesticides. This re-approval is in total contradiction with the European Green Deal that reinforced the precautionary principle, biodiversity protection, and the will of the Commission to phase out endocrine disruptors. PAN Europe considers going to court.
SNAP Comment: Cypermethrin is a pyrethroid and Flumioxazin is an unclassified type herbicide with little independent research but knowot be a bee toxicant. As of 17 December 2021, there are 9 cypermethrin and 22 Flumioxazin products (labels) registered in Canada.

Monsanto Pleads Guilty to Use of Illegal Glufosinate Pesticide in Hawaii (Sustainable Pulse,Dec 15 2021)
'In court documents filed last Thursday in Hawaii, Monsanto Company agreed to plead guilty to 30 environmental crimes related to the use of a pesticide on corn fields in Hawaii, and the company further agreed to plead guilty to two other charges related to the storage of a banned pesticide that were the subject of a 2019 Deferred Prosecution Agreement (DPA)..
The plea agreement calls for Monsanto to serve three years of probation, pay a total of $12 million and continue for another three years a comprehensive environmental compliance program that includes third-party auditor.
“Monsanto is a serial violator of federal environmental laws,” said United States Attorney Tracy L. Wilkison. “The company repeatedly violated laws related to highly regulated chemicals, exposing people to pesticides that can cause serious health problems.”'.

Pesticides and Parkinson’s Disease: The Toxic Effects of Pesticides on the Brain
(Beyond Pesticides, December 16, 2021) 'A study by Shanghai Jiao Tong University, China, finds Parkinson’s Disease (PD) risk increases with elevated levels of organochlorine (OCP) and organophosphate (OP) pesticides in blood. Among patients with PD, specific organochlorine compounds have greater associations with cognitive impairments, including depression and brain function. Research finds exposure to chemical toxicants, like pesticides, can cause neurotoxic effects or exacerbate preexisting chemical damage to the nervous system.
Of the organochlorines, α-HCH and propanil concentrations have the greatest association with PD risk through increasing reactive oxygen species (ROS) levels and decreasing mitochondrial membrane function in SH-SY5Y cells. However, only propanil induced accumulation of α-synuclein, a predominant protein in the brain tissue of PD patients.'
SNAP Comment: Propanil was historically used in Canada (oneof the 7 labels says that registration ended in 2000). Hexachlorocyclohexane ( HCH) was apparently not registered. Many organochlorines persist in the environment.

Repeat Offender Amazon.com Fined $2.5 Million for Illegal Pesticide Sales
restricted and general use pesticides
Repeat Offender Amazon.com Fined $2.5 Million for Illegal Pesticide Sales
(Beyond Pesticides, December 14, 2021) Multinational technology corporation Amazon.com, Inc will pay $2.5 million as part of a settlement with the Washington state Attorney General over illegal sales of highly toxic restricted use pesticides.
According to the legal complaint, between 2013-2020, Amazon sold thousands of both restricted and general use pesticides to individuals in the state of Washington without a pesticide sales license. The company failed to disclose this information to consumers, and also failed to connect information from buyers of restricted use pesticides, a requirement in Washington state. As a result of Amazon’s illegal activities, there are now thousands of highly hazardous pesticides being used in Washington without documentation on its use site or location. In addition to its own sales, the company is accused of facilitating illegal sales from third party dealers, who also violated aforementioned licensing and documentation requirements.
In addition to paying Washington State $2.5 million, under the consent decree Amazon is required to obtain a pesticide seller license if it plans to continue selling pesticides. It must track the pesticides it is listing for sale and prohibit illegal sales. If a customer “inadvertently” purchased a restricted use pesticide, Amazon is also required to notify them and work with the customer to dispose of the product, reimbursing the customer for their costs. Third-party sellers will also be required to obtain a license and maintain sales records.
Beyond the illegal sales, the company continues to sell pollinator-toxic insecticides on its website, ignoring the concerns of pollinator advocates that urged the company to stop. A non-exhaustive list produced by Beyond Pesticides at the time identified over 100 products dangerous to pollinators, many of which are still being sold by the company today.
SNAP Comment: None of the illegal products sold are listed in the article. I checked several links to the listed products of the list of 'still being sold today', and found ttem either taken down or 'currently unavailable'. This list contains neonicotinoids such as imidacloprid, but many with the active ingredient acetamiprid, clothianidin, thiacloprid or thiamethoxam. There is a button on the top left saying 'Deliver to Canada'. It is not only whether a particular pesticide is registered for use in Canada, the particular product containing it also has to be registered. I found that some listed products that say " Deliver to Canada' are not currently registered in Canada such as Ortho Rose and Flower Insect Killer, 24-Ounce, or Transport GHP Insecticide, both containing acetamiprid. So I guess this is a Canadian issue as well..

Pesticides Incorporated into Fabrics and Housewares Are Hazardous, and Not Adequately Regulated
(Beyond Pesticides, December 13, 2021) If you plan to give socks, sweatshirts, or other items of clothing as holiday gifts, you need to be aware that many such items are treated with toxic chemicals. Such treated items may be labeled as “odor free” and may contain nanosilver, triclosan (banned in soaps, but allowed in textile and household products), or other (undisclosed) chemicals hiding behind brand names such as Microban® or FreshIQ. Since it is not always possible to determine which chemical may be used in these textiles, the best option is to buy clothing that is organic or made locally. The Environmental Protection Agency (EPA) exempts treated articles from registration requirements under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Although the chemicals themselves may be registered antimicrobial pesticides, the treated products in which they are found—and which expose the public to them—are not considered pesticides. Besides clothing treated with antimicrobials to control odors, EPA also allows seeds, wood, paints, cutting boards, sponges, mops, and even toothbrushes to be treated with antimicrobial pesticides under the exemption—as long as claims made for the treatment only pertain to protecting the treated article.
SNAP comment: Although I did not find any Canadian registered products for Triclosan or FreshIQ, there are 3 Microban registered products. The one I checked was registered for adhesives, leather, textiles, paint, floor wax, pulp and paper and many more uses including for post harvest preservation of pears.

Court Steps In to Stop Pesticide Use Not Adequately Regulated, Protects Bees
Sulfoxalor insecticide banned in California
Court Steps In to Stop Pesticide Use Not Adequately Regulated, Protects Bees
(Beyond Pesticides, December 10, 2021) 'In a win for pollinators, a California Superior Court has issued a ruling that sulfoxaflor, a systemic pesticide that is “field legal” but “bee lethal,” can no longer be used in the state. The suit was brought by the Pollinator Stewardship Council and the American Beekeeping Federation.
Sulfoxaflor is an insecticide registered by the U.S. Environmental Protection Agency (EPA) for use in controlling sucking insects such as aphids, stink bugs, plant bugs, and thrips in agricultural production. It was registered in 2013 for use on many fruit and vegetable crops.... “In 2015, the U.S. Court of Appeals for the 9th Circuit ruled that federal regulators lacked adequate data to show the pesticide did not pose serious risk to pollinators, and the court vacated the agency’s ( EPA) approval of sulfoxaflor'. . . .for the EPA to proceed in registering sulfoxaflor for crops that do not attract bees, then re-registering it for bee-pollinating crops in subsequent years.
SNAP Comment: Sulfoxalor is not a neonicotinoid but has the same mode of action. There are currently 5 sulfoxaflor registered labels in Canada. One of them indicated it was registered both for ground and aerial application on fruits (including apples) and vegetables.

One Single Neonic Exposure Saps Wild Pollinator’s Ability to Reproduce
imidacloprid
One Single Neonic Exposure Saps Wild Pollinator’s Ability to Reproduce
(Beyond Pesticides, December 7, 2021) One exposure. That’s all it takes for wild bees to experience declines in reproduction and population growth from neonicotinoid insecticides, according to research recently published in the Proceedings of the National Academy of Sciences (PNAS). This incredible sensitivity is exactly the sort of process that could rapidly drive pollinator species into extinction. Researchers conducted their study during the first year by exposing a group of larval bees to the neonicotinoid imidacloprid through a ground drench at the highest rate on the label for the product AdmirePro, produced by Bayer... during the second year, some of the unexposed adults were dosed with the same rate of imidacloprid.
Orchard bees exposed to imidacloprid as adults during year two were 4% less likely to initiate nesting, and when they did, they created their nest 38% percent slower, and produced 30% less offspring than those left unexposed. This population also produced 49% fewer female offspring than unexposed bees. Larval bees that were exposed during year one, and subsequently established nests during year two also laid significantly (20%) fewer eggs.
These results add considerable urgency to efforts to stop pollinator declines. Imidacloprid can remain in soil for nearly a year, meaning that even if these chemicals were eliminated today, it could be two or more years before ground-nesting pollinators stop declining.
SNAP comment: This type of study is not yet included in the studies mandated for pesticide registration either in Canada ro the US. The whole body of independent studies (non-mandated) is not given appropriate consideration in pesticide registration or re-evaluations. This is in large part because of the process of risk-benefit assessment. As long as a pesticide is deemed 'useful', it doesn't really matter how many deleterious effects it has. It gets re-registered.

Pesticides Expenses Significantly Outweigh Economic Benefits
Pesticides Expenses Significantly Outweigh Economic Benefits
(Beyond Pesticides, This is from the report 'Pesticides ‘cost double the amount they yield,’ by the French-based organization Bureau for the Appraisal of Social Impacts for Citizen Information (BASIC). Moreover, the annual cost of increasing organic farms three-fold by 2030 is less than the cost of pesticides to society (i.e., adverse health and ecological effects from pesticide use and contamination). However, the price to pay from pesticide use encompasses much more than the products themselves. Researchers point to the need for government and health officials to consider the billion-dollar costs associated with adverse health effects from pesticide use, especially as studies confirm that pesticides cause cancer, Parkinson’s, and other diseases that are increasing'
The study finds that Europe pays nearly twice as much (2.3 billion Euros) in subsidies than is generated in economic return to sustain pesticide production and use in 2017. The profit generated by industry that same year was 900 million Euros. The report notes that without subsidies, lobbying, and payment of expenses associated with the adverse effects of pesticides, the pesticide sector would lack profitability. Moreover, the reports confirm intense pesticide use produces multiple harms. Declines in insect populations, birds, and sensitive organisms are prevalent among regions with extensive chemical use. The researchers warn that insufficient pesticide regulations do little to protect the occupational and general population from various toxic substances.
However, the BASIC report finds the number of pesticides used in agriculture doubled in the past 20 years, and so the economic damage is much greater than previous figures demonstrate. Although the pesticide industry carries out large-scale lobbying to defend current pesticide use, total costs for lobbying approaches 10 million euros per year, which is greater than the pesticide regulation budget for the European Food Safety Authority (EFSA).
SNAP Comment: And I always see Europe as 'safer' as they have adopted a preventative registration model rather than our widely debunked 'the dose makes the poison' model.

Pesticide Use on Island Resorts Tied to Biodiversity Collapse
Pesticide Use on Island Resorts Tied to Biodiversity Collapse
(Beyond Pesticides, December 8, 2021) . Oceanic islands, despite their small size, harbor 20% of all species, and 50% of endangered species, making conservation critically important in the context of a sixth mass extinction and insect apocalypse.
Results show that, compared to uninhabited islands, urban islands contain roughly half the number of species, while tourist islands contain approximately one third. On urban islands, researchers attribute the disparity to habitat fragmentation, loss of habitat quality, and loss of natural vegetation cover.
With increased occurrences of cosmetic landscaping, small gardens, golf courses, and other tourism-related activities, researchers thus attribute pesticide use as the driver of declines on tourist areas. Every tourist island studied indicates that they regularly apply insecticides, specifically synthetic pyrethroids like deltamethrin, in and around structures to manage common pests like mosquitoes, bedbugs, and cockroaches.

Houston Residents Sue City, Railroad, for Poisoning and Contamination Caused by Creosote Wood Preservative
(Beyond Pesticides, December 2, 2021) 'Thousands of residents in Houston, Texas are suing Union Pacific Railroad Company for contaminating their properties with highly hazardous creosote wood preservatives. One of these lawsuits comes from Latonya Payne, legal guardian of Corinthian Giles, a 13-year-old boy who died of leukemia after a five year battle with the disease. A recent report found that the community is in the midst of a childhood leukemia cancer cluster, with disease rates five times the national average. ...EPA is currently in the process of reauthorizing creosote use for another 15 years with the knowledge that it is virtually impossible to produce and use without causing contamination and poisoning. Creosote was used to treat and extend the life of railroad ties at a location in Houston’s Greater Fifth Ward up until 1984, but since that time a plume of contamination in the soil has slowly worked its way through the low-income, predominantly black community currently living near the old site..... In light of these “unique benefits,” the agency (EPA) did not even consider the viability of alternatives, such as steel, composites, and fiberglass that could replace the hazardous wood preservative process with non or less toxic materials.'

PACTPA 2.0: Putting people before pesticides
PACTPA 2.0: Putting people before pesticides (PANNA, dec 2021)
After a brief attempt in 2020, the Protect America’s Children from Toxic Pesticides Act (PACTPA) was re-introduced by Senator Cory Booker on November 23 of this year, and PAN is among the organizations that support its passage! This bill would overhaul U.S. pesticide regulations, ultimately mandating new rules to protect people and the environment. link to full text of bill.
PACTPA would:
- Ban dangerous pesticides including organophosphate insecticides, neonicotinoid insecticides and paraquat herbicides;
- Close loopholes that have allowed the EPA to issue emergency exemptions and conditional registrations to use pesticides even before they go through full health and safety reviews;
- Create a petition process for the people which will allow citizens to request review of pesticides that would otherwise be approved for use indefinitely;
- Support local community protective actions from preemption of veto by state law;
- Protect farmworkers from harm by requiring injury reports, directing EPA review of these reports, improved pesticide label instructions and requiring labels in Spanish and any other language that can be shown to have 500 or more applicators using that language; and
- Broaden the knowledge base by requiring suspension and review of pesticides deemed unsafe by other nations.
SNAP Comment: These changes would also be welcome in Canada with the following differences. Although conditional registrations are apparently not allowed in Canada any more, Under Section 18 of the Pest Control Products Regulations, emergency registration is still allowed 'for a period not exceeding one year'.and cannot re renewed. Point 5 mentions requuiring injury reports. In Canada,the only mandatory reporting of negative effects has to be doneby the manufacturs themselves. MDs or the public caan submit injury reports but do not have to so that would be great addition for Canada, and not only for farmworkers.

California Supreme Court Upholds $87M Award in Glyphosate Damage Lawsuit, Bayer/Monsanto Challenge Fails
CA Supreme Court Upholds $87M Award in Glyphosate Damage Lawsuit, Bayer/Monsanto Challenge Fails
(Beyond Pesticides, November 30, 2021) The chronicle of developments in the glyphosate saga has just grown longer: the California Supreme Court has rejected a request by Bayer AG for review of the August 2021 First District Court of Appeal (San Francisco) ruling, for the plaintiffs, that Monsanto knowingly marketed a product — Roundup — whose active ingredient (glyphosate) could be dangerous. The $87 million in damages awarded to the plaintiffs in the litigation, Alberta and Alva Pilliod, has thus survived Bayer’s challenge.
Lest the announcement generate too much excitement (welcome as the move is), Beyond Pesticides noted that: (1) this still leaves Roundup on the market for agricultural food production — where glyphosate gets the heaviest use — and particularly, for use with genetically engineered crops; and (2) what will replace glyphosate in the company’s herbicide formulations is not yet clear, but the residential herbicide market will likely shift to other toxic weed killers to replace glyphosate uses.

Climate Change Consequences and the Organic Response
Climate Change Consequences and the Organic Response (Pesticides and You, vol 27 , No1, Spring 2007)
'Since 1981, data from the FST has revealed that soil under organic agriculture management can accumulate about 1,000 pounds of carbon per acre foot of soil each year (1,123 kg/ha/ yr metric). This accumulation is equal to about 3,500 pounds of carbon dioxide per acre taken from the air and sequestered into soil organic matter.... Conventional no till (or no tillage where plowing is replaced by herbicides) soil carbon increases in just the first few inches and this effect is extinguished at 3 to 6 inches (5 to 10 cm) or before this level,.. Why does the soil carbon level increase in organic systems but not in conventional systems when crop biomass is so similar? We believe the answer lies in the different decay rates of soil organic matter under different management systems.'

A powerful and underappreciated ally in the climate crisis? Fungi Mycorrhizal fungal networks are a major global carbon sink. When we destroy them, we sabotage our efforts to limit global heating (Toby Kiers and Merlin Sheldrake, The guardian, Tue 30 Nov 2021)
'Through fungal activity, carbon floods into the soil, where it supports intricate food webs – about 25% of all of the planet’s species live underground. Much of it remains in the soil, making underground ecosystems the stable store of 75% of all terrestrial carbon.... Logging wreaks havoc below ground, decreasing the abundance of mycorrhizal fungi by as much as 95%, and the diversity of fungal communities by as much as 75%. A large study published in 2018 suggested that the “alarming deterioration” of the health of trees across Europe was caused by a disruption of their mycorrhizal relationships, brought about by nitrogen pollution from fossil fuel combustion and agricultural fertiliser.
Globally, at least 5bn tons of carbon dioxide are sequestered within mycorrhizal networks each year, a quantity roughly equivalent to the amount of carbon dioxide emitted annually by the US (unpublished data suggests this figure is closer to 17bn tons). Even small reductions in the prevalence of fungal networks have significant consequences: a release of just 0.1% of the carbon now stored in Europe’s soils is equal to the annual emissions from 100m cars.'

Pesticide Exposure Contributes to Preterm Births and Low Birth Weight
(Beyond Pesticides, November 18, 2021) A study published by King George’s Medical University, India, finds exposure to xenobiotic substances like pesticides during pregnancy increases risks associated with preterm birth, including a rise in cesarean section (C-section) deliveries and a decrease in fetal body weight. All of the blood samples from premature newborns and their mothers have higher levels of OCPs (organochlorine pesticides) than full-term newborns. Aldrin, dieldrin, and hexachlorocyclohexane (HCH) are the most prominent OCPs present in maternal and umbilical cord blood samples, followed by DDT, endosulfan, and endrin aldehyde. However, blood samples also contain concentrations of other pesticide types including, organophosphates (OPs) (i.e., dichlorvos, malathion, chlorpyrifos, profenofos), synthetic pyrethroids (i.e., cypermethrin, fenvalerate, cyhalothrin-L, deltamethrin, cyfluthrin), and neonicotinoids (neonics) (i.e., imidacloprid). Regarding specific birth outcomes, DDT metabolite DDE and dieldrin have significant associations with low birth weight.

EPA finds two widely used pesticides harm majority of endangered species
EPA finds two widely used pesticides harm majority of endangered species (By Ashley Curtin, Nation of Change November 17, 2021) US story.
Atrazine and glyphosate are both causing severe harm to many of the plants and animals protected under the Endangered Species Act. “It’s no surprise that these chemical poisons are causing severe harm to imperiled wildlife since U.S. use exceeds 70 million pounds of atrazine and 300 million pounds of glyphosate every year,” Nathan Donley, environmental health science director at the Center for Biological Diversity, said.
SNAP Comment: While atrazine use is low in Saskatchewan (11 kg in 2003), likely because there was hardly any corn production at that time, glyphosate was the top selling herbicide in 2003 with over 9 million kgs sold (9/10th of total commercial sales based on 75% reporting). Note that atrazine is widely used in southern Ontario and Quebec at the very least.

Mimicking a pulse that may come from a nearby insecticide application, each group of ditches was dosed every two weeks for a period of three months.'
'By the end of the study, compared to the control group overall insect biomass declined by 11, 4, and 50% along a gradient of increasing amounts of neonic dosing. Diptera, the large order of flies, accounted for the bulk of biomass declines. Within one order of Diptera known as Chironomidae midges, populations crashed from an initial identification of 29 species down to a single species in the highest dosed ditches.'
A range of other aquatic insects such as beetles, dragonflies, caddisfles and mayflies were also harmed.

Organic Takes on Existential Health and Environmental Crises, While Some Critics Lack Context (Response to New Yorker piece)
if there is money to be made somewhere, someone will commit fraud. It should not reflect on other honest producers.
(Beyond Pesticides, November 12, 2021) 'Omnivorous readers may have encountered an article, in the November 15 issue of The New Yorker magazine, titled — at best misleadingly, and certainly sensationally — “The Great Organic-Food Fraud.”
What the article fails to do is render any comprehensive picture of how National Organic Program certification and inspection work, and the underlying principles, values, and standards in federal law (the Organic Foods Production Act), nor does it review either the benefits of organic agriculture broadly or the massive harmful impacts of conventional, chemical-intensive agriculture in the U.S. Beyond Pesticides provides ballast, in this Daily News Blog article, to the failings of the New Yorker article and the damage it might do to the organic movement.'

Unless You Go Organic, Switching to ‘Healthier’ Mediterranean Diet Increases Pesticide Exposure Three-fold
(Beyond Pesticides, November 9, 2021)' Replacing a modern, ‘western’ diet of highly processed foods with a Mediterranean diet filled with conventional, chemically-grown fruits and vegetables triples exposure to toxic pesticides, according to research recently published in The American Journal of Clinical Nutrition. For organophosphate insecticides in particular, levels increased nearly 4x (from 7 to 25 μg/d)' ( urine concnetration).. 'Between the organic and conventional Mediterranean diet, individuals that ate organic had 91% lower pesticide residue than those consuming foods only produced through conventional chemical farming practices. Researchers found that the primary source for pesticide residue came from chemically grown fruit, vegetables, and whole grain cereals. The research is so convincing, it may be possible to base future public health research upon. “One of the difficulties of assessing the public health impacts of dietary exposure to pesticides is that once pesticides are widely used in food production everybody gets exposed,” said Leonidas Rempelos, PhD. “This study demonstrated the potential of using organic food consumers as a ‘low pesticide exposure control group’ to investigate the effect currently used and newly released pesticides on public health.”

Secret Inert Ingredient in ‘Bee Safe’ Pesticide Found to Kill Bumblebees
Secret Inert Ingredient in ‘Bee Safe’ Pesticide Found to Kill Bumblebees
(Beyond Pesticides, November 11, 2021)' Evidence is building that so-called ‘inert’ ingredients in pesticide formulations are harming pollinators and undermining regulatory determinations that designate products as ‘bee-safe.’ According to a new study published in Scientific Reports, the fungicide Amistar causes lethal and sublethal effects that can be primarily attributed not to its active ingredient azoxystrobin, but to alcohol ethoxylates, a co-formulant, or inert ingredient intentionally added to a pesticide formulation.
Further, Amistar’s formulation in Europe may differ from its formulation in the United States and other countries, despite that fact that chemical company Syngenta/ChemChina is the primary registrant in both locations.
Researchers found that bees that weighed more at the beginning of the study were more likely to survive. That is because alcohol ethoxylates were causing sub-lethal impacts that didn’t necessary kill every exposed bumblebee outright. Dissection after the experiment determined that alcohol ethoxylates were creating dark brown patches in bumblebee guts. This was leading to a range of observable warning signs. “Whilst 30 percent of bees exposed to the fungicide product died, the other 70 percent were far from healthy; they had damaged guts, were eating about half as much food and were losing weight,” said study coauthor Ed Straw, PhD. “Pesticide regulation typically only looks at whether or not a bee dies, but we found that even bees who survive can be under severe stress.”
...other research done under field-realistic conditions within the PoshBee project show similar results. This combination of results, enabled by this European-wide project, really supports the idea that co-formulants in pesticides need to be considered more seriously as threats to bee health.”
SNAP comment: In Canada, inerts are called formulants/Canada. The CAS number for alcohol ethoxylates is 84133-50-6. They are listed as a formulant in the latest PMRA formulants list (2017). It is listed in category 4B "formulants of minimum concern under specific conditions of use". Section 4.6:"When a formulant reaches List 4B, no further regulatory action is anticipated unless the use pattern for which it is being considered is beyond that approved, in which case the PMRA will require an independent review". A formulants are still secret except if very toxic or allergens, I suspect there is no listing of alcohol ethoxylates in pesticide formulations or on MSDS sheets. As of 18 November 2021, there are 44 PMRA registered products containing azoxystrobin, none with the name Amistar.

Researchers Uncovering Patterns that Help to Explain Chemical Sensitivities
Researchers Uncovering Patterns that Help to Explain Chemical Sensitivities
(Beyond Pesticides, November 3, 2021) A significant and increasing share of the U.S. ( and Canadian) population is reporting sensitivities to certain chemicals.
'TILT is characterized by a two-step process. First, there is an “initiation exposure event,” whereby an individual is either repeatedly exposed to low levels of certain chemicals, or experiences a major exposure incident. In the second stage, affected individuals are “triggered” even by minute exposures, not only to the chemical that affected them in the first place, but also to other chemicals that didn’t affect them previously. Exposure to a trigger results in a range of debilitating symptoms, such as weakness, chronic fatigue, asthma, rash, and headache, that can sometimes leave exposed individuals incapacitated and unable to lead a normal life. This disease is not similar to pollen allergies that can be tested by immunoglobin antibodies. TILT sufferers are often bounced from doctor to doctor based on individual symptoms, have significant difficulties receiving a diagnosis, and must navigate a world filled with triggering compounds, ranging from pesticides, to fragrances, molds, and other indoor air contaminants, traffic exhaust, pharmaceutical drugs, certain food, or food and drug combinations, or other volatile compounds.
They found that the most prevalent initial exposure was from chemicals considered to be Volatile Organic Compounds (VOCs) or Semi-Volatile Organic Compounds, with pesticides next, and combustion products the third most frequent exposure. The study notes, “As a broader category, synthetic organic chemicals and their combustion products were the primary exposures associated with chemical intolerance, including pesticides, peroxides, nerve agents, anti-nerve agent drugs, lubricants and additives, xylene, benzene, and acetone.
TheQuick Environmental Exposure and Sensitivity Inventory", or QEESI test, an internationally recognized tool for quickly evaluating an individual for TILT, and can be used both by medical professionals and patients. The presence of TILT undermines classical toxicological concept that “the dose makes the poison.” The authors indicate that a better phrase may be that “dose plus host makes the poison,” with an understanding that past exposures and various genetic factors are likely at play in terms of individual tolerance to environmental pollutants.
SNAP Comment: many organic chemicals including petroleum products including xylene, benzene, naphta, ethylene, kerosene, toluene, naphthalene and more are still listed in the PMRA's currentl list of formulants so VOCs and pesticides are far from being mutually exclusive.

(GENEVA, 13 October 2021)'The Campo Agua’e indigenous community lives in an area closely surrounded by large commercial farms that use fumigation, a process that utilizes chemical smoke to kill pests, to produce genetically modified soybeans. The fumigation, including the use of banned agrochemicals continuously for more than ten years in the area, had killed indigenous community’ chickens and ducks, affected subsistence crops and fruit trees, impacted hunting, fishing and foraging resources, contaminated the waterways and harmed people’s health.'
Then it goes on to mention lack of government monitoring of spraying and making full reparation including repairing environmental damage.
SNAP comment: So under human rights, there is a duty to monitor spraying? There are a few Canadian and provincial pesticide inspectors, way too few to monitor much, so Canada also suffers from a lack of monitoring. Depending on which chemicals were fumigated, and what their half life is, it may not be possible to repair environmental contamination for a long time. The ecological damage would be even harder to reverse.filed under Human Rights

(Beyond Pesticides, October 27, 2021) 'Declines in pollinator populations throughout the world may result in the loss of tens of thousands of wild flowering plants that rely on their services, according to research published this month in the journal Science Advances. “Our paper provides the first global estimate of how many plant species mostly or completely rely on animal pollinators to make seeds and thus to reproduce,” wrote author James Rodger, PhD,'
About 175,000 plant species – half of all flowering plants, depend on pollinators. "This means declines in pollinators could cause major disruptions in natural ecosystems, including loss of biodiversity.” 'Accordingly, without pollinators half of plant species would experience a reduction in fertility by over 80%, and one third of flowering plant species with no longer produce seeds at all.'

Study on cotton production. 'Predator communities were found to be much more diverse (7 to 10x more) in cover cropped fields. Researchers found the benefits of cover cropping to be most pronounced in the early spring. But as the cover crop degrades, differences between cover cropped and control plot predator communities began to even out.' However, termination of the cover crop utilized an unnamed chemical herbicide. Thus a range of predator insects that may have assisted in further, or more sustained pest management may have been killed off by the use of a chemical to terminate the cover crop. '

Common Fungicide Causes a Decrease in Antioxidant Responsible for Defense Against Diseases like COVID-19
the fungicide fludioxonil
(Beyond Pesticides, October 8, 2020) 'Research from the University of Wisconsin—Madison (UWM), suggests that fludioxonil—a commonly used agricultural fungicide—decreases the human body’s ability to defend itself against illnesses, like COVID-19, and promotes disease permanency. Tristan Brandhorst, a Ph.D. scientist at UWM, notes that a pesticide-induced reduction in the antioxidant glutathione could be responsible for this lack of bodily defense against disease. Dr. Brandhorst recently discovered that the chemical causes metabolic shock to fungi, hindering glucose transport across the cell membrane. Additionally, further analysis finds that exposure to fludioxonil decreases glutathione levels in non-fungal cells, promoting “the ability of the fungicide fludioxonil to act on a sugar-metabolizing enzyme common to all cells, and to produce the damaging compound methylglyoxal.”

(Beyond Pesticides, October 6, 2021) 'Agricultural soils under monoculture cropping systems are not as healthy as soils with diverse plantings, finds research recently published in the journal Agrosystems, Geosciences and Environment. Soil and soil quality are declining rapidly in the United States and around the world, with recent data indicating that the U.S. Corn Belt has lost 35% of its topsoil.' The research compared a soy,/corn monocultures to perennial grass. 'The study notes these perennial systems have much more microbial diversity, over eight times more mycorrhizal fungi, and higher ratios of fungi to bacteria. The higher ratio of fungi to bacteria is likely indicative of the frequency of plowing in the monoculture systems, which occurred each year after harvest, according to the study. Repeated tillage breaks fungal connections that help stabilize soil, which can lead to worsening soil structure.
Prior studies that utilize the long-term cropping systems studied in the current paper indicated the regular use of 28% urea-ammonium nitrate fertilizer, glyphosate, glufosinate, and atrazine have a strong propensity to harm soil health.'

(Beyond Pesticides, July 20, 2021) Chlorpyrifos exposure results in the expression of genetic mutations associated with autism spectrum disorder in a laboratory model, finds research published in Environmental Health Perspectives by scientists at Johns Hopkins Bloomberg School of Public Health....Organoids were exposed to chlorpyrifos at four and eight weeks of development, representing a short term, high exposure scenario. “High-dose, short-term experimental exposures do not reflect the real-life situation, but they give us a starting point to identify genetic variants that might make individuals more susceptible to toxicants,” says Dr. Smirnova.

Report Finds True Cost of Food in 2019 Was $2.1 Trillion in Adverse Health, Environmental, and Other Effects
(Beyond Pesticides, July 23, 2021) The Rockefeller Foundation has just published a report, True Cost of Food: Measuring What Matters to Transform the U.S. Food System, which identifies the real-but-under-recognized downsides of the U.S. food system.
'The report calls for a true accounting of the costs of food in the U.S. Beyond Pesticides welcomes the broad framework of the report, but notes that a true accounting would necessarily include the costs of the externalities of conventional agriculture, including those related to pesticides: the costs of pollution and its cleanup (when that even happens), of lost pollination and biodiversity, of lost productivity from illness, and of health care costs related to pesticide use. Remarkably, for all its repetition of deleterious impacts on climate, biodiversity, and health, the report barely mentions either pesticides’ roles in causing such impacts, or the clear solution to so many of the negatives in the food system — organic, regenerative agriculture.'

Chemicals, including Pesticides, in Wastewater Discharge Contaminate Oysters in Pacific Northwest
(Beyond Pesticides, July 08, 2021) 'A Portland State University (PSU) study finds oysters of varying distances from wastewater discharge pipes along the Oregon and Washington state coast contain low levels of chemical contaminants....Although wastewater treatment facilities clean water draining from sinks and toilets, the process does not adequately remove all contaminants. The process can leave behind pharmaceutical drugs and personal care products (e. g., shampoos, make-up, deodorant) residues in treated water. PSU has already found that pesticides from the forestry industry threaten clams, mussels, oysters (bivalves) along the Oregon coast.
Although this study finds that chemical concentrations present in oysters remain under federally established guidelines, aquatic environments continuously encounter environmental pollutants and toxic compounds. These contaminants are known to have harmful biological consequences on both aquatic and terrestrial organisms.
The use of pharmaceuticals, like antibiotics and antifungals treatments, and pesticides in local marine ecosystems (e.g., insecticides to control sea lice in farmed salmon) results in coastal habitat loss and genetic health risks like pest resistance among wild marine organisms.'

Widely used neonic insecticides may be a threat to mammals, too
Neonicotinoids, used on corn seed and other crops, are already accused of contributing to declines of insect pollinators. Now there’s evidence they can also harm rabbits, birds, and deer.(By Elizabeth Royte, Food and Environment Reporting Network, February 5, 2021)'Over the past several years, scientists have found that only about 5 percent of neonic seed coatings are taken up by crop plants. The rest washes or wears off seeds. The chemicals accumulate in soils and waterways, where a wide range of wildlife is exposed to them. Evidence is growing that compounds tailored to take out invertebrates can also harm mammals, birds, and fish. In a 2019 study, Roy set up camera traps in agricultural fields where she had deliberately spilled treated seed. Her motion-triggered cameras recorded more than a dozen bird species (including ring-necked pheasants, geese, and turkeys), plus bears, raccoons, rodents, rabbits, foxes, and skunks, all feeding on the treated seed.'

This covers effects of all herbicide used in Oregon, including glyphosate. Biodiversity decreased in plots sprayed once (light spraying) twice (industrial standard) or 3 times (experimental). Wildlife loss is likely due habitat loss due to herbicide use. Although tree growth is 18-20% higher in treated plots, the red spruce germinates very well under canopy and just has to be released by cutting stems besides it. Economic discounting analysis indicates that it likely doesn't 'pay'; to spray.

(Beyond Pesticides, July 1, 2021) Yellow fever mosquitoes (Aedes aegypti) are evolving resistance to the pyrethroid insecticide permethrin, according to a study published by Colorado State University, highlighting the need to adopt ecologically-based mosquito management. Widespread, intensive use of the pesticide in mosquito control has allowed genetic mutations to persist among these mosquito populations, causing subsequent resistance to permethrin. Insecticide resistance has been an issue since the introduction of DDT (dichlorodiphenyltrichloroethane) in the 1940s.

Conventional Meats Contaminated with Multi-Drug Resistant Bacteria, at Significantly Higher Rates than Organic Meats
about antibiiotic resistance
(Beyond Pesticides, May 18, 2021) Organic meat is far less likely to be adulterated with multi-drug resistant bacteria (MDRB) than conventional meat, according a study published earlier this month in Environmental Health Perspectives.
Organic is not safer by chance, but by design. Organic standards, governed by the Organic Foods Production Act of 1990, were crafted with the goal of protecting public health and ecosystem services. Organic standards prohibit the use of antibiotics in poultry after their second day of life, and in mammals after the mother’s third trimester. Organic certified meats are also required to follow a stricter processing protocol, and in split operations organic meats cannot be processed on the same equipment as conventional meats without first undergoing cleaning and disinfecting.
In addition to food safety, past studies have found organic meats and other animal products to be more nutrient dense than its conventional counterparts.'

This new Commercial Herbicide Analysis highlights the adverse health and environmental effects of widely available toxic pesticides while encouraging retailers to expand on—and consumers to use—safer, least/non-toxic pesticide products.
The analysis...reveals that approximately half of all Home Depot herbicide products (24 of 51) and Lowe’s herbicide products (23 of 40) contain ingredients considered Highly Hazardous Pesticides (HPPs).
The following active ingredients pose the most harm to human, animal, and ecosystem health, including cancer, reproductive harm, neurotoxicity, and hormone (endocrine) disruption: glyphosate, 2,4-D, dicamba, mecoprop, and pendimethalin. Of these five chemicals, all but dicamba are classifiable as HHPs. View the analysis

Outrage as regulators let pesticides from factory pollute US town for yearsContamination from an ethanol plant in Mead, Nebraska, came from some of the world’s largest agricultural companies (The Guardian, Carey Gillam, 29 May 2021) Nebraska story.
SNAP Comment: I sure hope that the new canola crushing plants in Regina, apparenlty for oil (some for diesel replacement) production, will not accept treated seeds In any case, .the increase in canola porduction will undoubtedly bring an increase in pesticide use.
'The state attorney general’s office then sued the company for multiple alleged environmental violations, citing “an ongoing threat to the environment”, and late last month Nebraska lawmakers passed a bill restricting the use of pesticide-treated seeds for ethanol production.
Fish die-offs are reported miles downstream from the plant. University researchers have reported the decimation of dozens of honeybee colonies, and state officials have received reports of sick and dying geese and other birds, as well as disoriented dogs and unexplained ailments in people.
Regulators said they have found unsafe pesticide levels in a farm pond, and water used for drinking and for irrigating crops is also feared contaminated, according to records within the Nebraska department of environment and energy (NDEE). Pesticide residues have been detected in soil samples taken from an area park.
AltEn advertised itself as a “green recycling” location where agricultural companies could dispose of unwanted supplies of these pesticide-treated seeds. Bayer AG, which owns Monsanto, along with Syngenta, Corteva, and other large companies, were among those dumping seeds coated with an array of insecticides and fungicides at AltEn, according to AltEn marketing materials.
The situation is but the latest example of how industrial agricultural practices can create hazards dangerous to human and environmental health, according to Blood, who grew up on a farm in Hastings, Nebraska, and suspects cancers developed by many Hastings residents were linked to chemicals in the soil and water.

Conflicts of interest: Not a good look for science (PAN, 20 May 2021)
SNAP Comment: These tactics have all been developed and widely practiced by industry for decades on a multitude of products and issues including pesticides. Now we see them used to destroy democracy in the USA.
'There are several case examples covered in this 95-page INEP publication, and it’s really worth a read. One example from 2020, exposed in Environmental Health News, was an article on endocrine disruption published by 19 toxicologists in eight different journals. However, it was not a work of original research; in reality it was an opinion piece by toxicologists with ties to the chemical industry.
None of these toxicologists had studied endocrinology or endocrine disrupting chemicals.
In 2013, the same group of toxicologists published an article in six toxicology journals, around the time of a European Union legislative effort to regulate endocrine disrupting compounds. These editorials were meant to “foster the views of the chemical industry at the expense of human health.” This is not a good look for toxicology...
The tactics used to confuse the science around tobacco and more recently around the climate crisis include: distraction, creating doubt, calling for more studies (because of doubts!). Sound familiar? This is not new news, we’ve seen the pesticide industry employ these same tactics time and time again, specifically around the neurotoxic pesticide chlorpyrifos over the past 20 years.

The main ingredient in RoundUp doesn’t just kill plants. It harms beetles, too. Glyphosate seems to interrupt a key symbiotic relationship in sawtooth grain beetles. (Philip Kieffer, Popular Science, May 13, 2021)
'But sawtooth grain beetles rely on a symbiotic relationship with a particular type of (unnamed) bacteria to build their shells. That bacteria in turn uses the shikimate pathway to manufacture the raw building blocks the beetles need.
Glyphosate appears to kill off those partners. After exposure to the chemical, the beetles make softer, weaker shells. It doesn’t kill them outright, but it leaves them more vulnerable. “They are doing way worse,” Engl says. “Their cuticle is thinner, and this is creating a higher risk of desiccation and higher mortality.”
The sawtoothed grain beetle is a crop pest, but Engl says it’s a model for all kinds of other beetles, which constitute about a quarter of all known animal species. “The beetle is generally used by us to understand the associations between insects, their microbial partners, and their ecological importance, so it’s a proxy for many insects,” Engl says.'

(Beyond Pesticides, April 21, 2021) 'The vast majority of bald and golden eagles in the United States are contaminated with toxic anticoagulant rodenticides, according to research published in the journal PLOS One earlier this month.
Prior studies have deemed anticoagulant rodenticides “super-predators” in ecosystems for the widespread damage that can result from their use. This is because rodents that eat these chemicals, often contained in toxic baits, do not die immediately. While a rodent is likely to die from this poison, ingesting it also turns it into a sort of poison trojan horse for any predator that may take advantage of its slow decline. An eagle that eats a poisoned rodent at the edge of death will be the next to succumb to the anticoagulant effects of the chemical.

Living Within 2.5 Miles of Chemical Farming Increases Risk of Childhood Brain Tumors
(Beyond Pesticides, April 6, 2021) Pregnant women living within 2.5 miles of agricultural pesticide applications have an increased risk that their child will develop central nervous system (CNS) tumors, according to a study published in the journal Environmental Research by a team at University of California, Los Angeles. The results are particularly concerning as it reveals that individuals do not have to be in close contact with pesticides for risky, health-harming exposures to occur. For astrocytoma tumors, the use of the pesticides bromacil, thiophanate-methyl, triforine, and kresoxim-methyl increased risk of tumor development. Medulloblastoma was associated with the use of chlorothalonil, propiconazole, dimethoate, and linuron. Development of ependymoma was linked to nearby use of thiophanate-methyl. In sum, the pesticides chlorthalonil, bromacil, thiophanate-methyl, triforine, kresoxim-methyl, propiconazole, dimethoate, and linuron were all linked to elevated rates of a CNS tumor.
SNAP Comment: California is one of the only locations where such a study can be performed because they keep pesticide use data. In Saskatchewan, we don't even have pesticide sales data since 2003! The transition from farmland to residential is equally abrupt in SK. As of 20 April 2021, the number of registered products of the pesticides quoted above are registered by the PMRA: Linuron 4 (herbicide) (annual weeds in crops); bromacil, 6 (herbicide); thiophanate-methyl,(fungicide) 13. included uses for seed potatoes ((not an extensive search of uses); Triforine,2 (fungicide) for blueberries, other berries and fruit); kresoxim-methyl 2 (fungicide) for pear scab and powdery mildew; chlorothalonil,38 labels (fungicide) formarket gardens, corn and fruit, golf courses, ornamentals and aerial applications (not an extensive search of uses); propiconazole,65 labels (fungicide) turf, golf courses.

Roundup Shown to Kill Bees—But Not How You Might Expect
Roundup Shown to Kill Bees—But Not How You Might Expect
(Beyond Pesticides, April 20, 2021) 'Roundup products manufactured by Bayer-Monsanto kill exposed bumblebees at high rates, according to a new study published in the Journal of Applied Ecology, which points to undisclosed inert ingredients (those that typically make up a majority of the product formulation) as the primary culprit.
Bumblebees sprayed with consumer use Roundup Ready-To-Use (contains glyphosate) experienced a shocking 94% mortality. Subsequent experiments were conducted at lower application rates for that product, and significant mortality was seen for the 1:1 dilution (98% mortality) as well as the 1:3 dilution rate (78% mortality). The agricultural use Roundup Proactive (contains glyphosate) saw lower rates of death at 30%. Weedol, a glyphosate-based consumer product, displayed a mortality rate (6%) similar to the unexposed control group of bumblebees (4%). However, Roundup Speed Ultra' (containing acetic acid and no glyphosate) 'was found to kill 96% of exposed pollinators.'.

Pesticides Are More Widespread in Both Conventional and Organic Agricultural Soils than Previously Thought
Swiss study
(Beyond Pesticides, April 1, 2021) 'A legacy of toxic pesticide use in agriculture is showing up as residues on organic farms, emphasizing the threat of a history of weak regulatory standards that has left farmland poisoned and the urgent need to transition to organic. A study, published in Environmental Science & Technology, documents the findings of pesticide residues on organic farmland and shows a decrease in residues after transition, with lingering effects for decades.' Researchers studied residues of 46 current pesticides. Conventional soils had 9 times higher pesticide contamination and the longer land was organic, the lower the residue. These pesticide residues affect soil organisms and consequently soil processes and functions. More studies are needed.

Other uses of pesticides in Canadian forests
- In addition to forest companies, many provincial department of highways spray road edges to maintain visibility, railroads spray rail beds for weeds, and power companies spray under power lines. If you become aware of other uses, let SNAP know.
- Tree seedlings planted by tree planters also generally seem to be treated, likely with fungicide or insecticides as many tree planters reported to me. I needmore details about this use.
- At lest Saskatchewan sprays when needed for insects such as Spruce Budworm and Tent Caterpillars. Btk is an acceptable natural insecticide for organic agriculture and is effective for both. It has generally replaced much more toxic insecticides such as DDT and fenitrothion. Each province would have different rules about this.

(Beyond Pesticides, March 18, 2021) A new study published in Environmental Toxicology and Pharmacology finds chronic (long-term) organophosphate (OP) pesticide exposure increases adverse health and cancer risk for U.S.women relative to men. Study results demonstrate that non-smoking women with higher concentrations of OP metabolites are at greater risk of developing cardiovascular disease, bronchitis, asthma, and total cancer, including breast cancer. OP exposure contributes most significantly to cardiovascular disease risk in women 60 to 85 years old. Increasing prescription drug use to treat pulmonary issues among women with higher OP concentrations indicates a relationship between exposure and health issues. Although breast cancer risk is highest among women overall, female smokers have a significantly higher risk of developing breast cancer in combination with OP exposure. Lastly, OP exposure among male smokers can increase rates of prostate cancer.

Ecosystem Health: Pesticide Use from Forest Management Practices Threatens Essential West Coast Marine Organisms
(Beyond Pesticides, March 11, 2021) A Portland State University (PSU) study finds that pesticides from the forestry industry threaten clams, mussels, oysters (bivalves) along the Oregon state coast. Bivalves are excellent indicator species, signaling environmental contamination through their sedimentary, filter-feeding diet. However, continuous pesticide inputs—from various forestry management regimes—into watersheds along Oregon’s coastal zone endanger these species in downstream rivers and estuaries (river mouths).... there is a lack of studies addressing the overall impact of multiple chemical mixtures and application on watersheds and subsequent aquatic transport.
The study results detect 12 different chemical compounds (two herbicides, three fungicides, and seven insecticides) in both water and bivalve samples—five of which are current-use pesticides in forest management. Although pesticide concentration and type vary by season, organism, and watershed location, 38 percent of bivalve samples harbor pesticide concentrations high enough to accumulate in tissues. Indaziflam (a current-use herbicide in Oregon forestry) is present in seven percent of bivalve samples. Furthermore, water samples find current-use herbicides hexazinone and atrazine, and banned pesticides like DDT/DDE contribute to aquatic contamination downstream. The study uncovers that most contamination occurs along the Central Oregon Coast in the Siuslaw and Smith watersheds
Additionally, coastal and offshore aquaculture (farming of aquatic organisms) presents a new, looming threat to marine health. Namely, the use of antibiotics and pesticides on local marine ecosystems (e.g., insecticides to control sea lice in farmed salmon) results in coastal habitat loss and genetic and health risks to wild marine populations.
SNAP Comment: As of 23 March 2021, 7 Indaziflam products are registered in Canada, most for orchards and one for non residential/non-crop areas which includes railroads and utilities but not specifically forestry. 5 Hexazinone products with 3 used for alfalfa and blueberries, and 2 for woodland management and Christmas tree plantations, and 12 Atrazine labels which seem to be for use mostly in corn and agriculture. I suspect that extensive water testing in Canada would indicate the presence of many pesticides that likely could accumulate in bivalves and other aquatic organisms. If these particular products were found, the source would likely be agricultural and not forestry.

Despite 1,700 Dog and Cat Deaths from Flea Collars, EPA Silent; Children at Risk
(Beyond Pesticides, March 5, 2021) Pet owners will be alarmed to read the report, by USA Today, that a popular flea and tick collar — Seresto, developed by Bayer and sold by Elanco — has been linked to nearly 1,700 pet deaths, injuries to tens of thousands of animals, and harm to hundreds of people... Beyond Pesticides and other advocates have warned of the toxicity of pet pesticide treatments, not only to the animals themselves, but also, to children and other household members. There are nontoxic ways to protect pets from fleas and other pests, and to protect human family members at the same time.
The active pesticide ingredients in the Seresto pet collars are imidacloprid and flumethrin. The neonicotinoid insecticide imidacloprid is a commonly used pesticide associated with serious health and environmental decline. ... Flumethrin is a chemical in the pyrethroid class of synthetic neurotoxic insecticides, which have been repeatedly linked to neurological issues, such as seizures and learning disabilities in children, and to gastrointestinal distress, as well as to damage to non-target invertebrates, according to EPA’s own analysis.'

Minnesota Deer Threatened by Ubiquitous Neonicotinoid Contamination, According to Study
Minnesota Deer Threatened by Ubiquitous Neonicotinoid Contamination, According to Study (Beyond Pesticides, March 10, 2021)
'Preliminary results reveal that 61% of deer spleen samples contained neonicotinoids. Although MDNR notes that these levels are below allowable levels set by U.S. Environmental Protection Agency (EPA) for consumption of other foods like fruit and beef, it has not yet released exact numbers, and that fact alone does not equate to safety.
Subsequent reporting from the Minneapolis Star Tribune indicates that some of the deer spleens tested contained detections well above levels found in the South Dakota study that result in fawn birth defects (.33 parts per billion). A letter written to hunters who provided MDNR spleen samples informed them that initial testing found levels as high as 6.1 parts per billion.
The detections were not simply from one particular location, but widespread throughout the state, even in remote, forested areas. These data reinforce long-standing calls by scientists and conservation groups to eliminate the use of neonicotinoids due to their broad ranging impacts on ecosystems. In 2018, the Task Force on Systemic Pesticides, an international group of over 240 scientists published a Worldwide Integrated Assessment (WIA) synthesizing 1,121 published peer-reviewed studies over the last five years. The scientists found that, “neonics impact all species that chew a plant, sip its sap, drink its nectar, eat its pollen or fruit and these impacts cascade through an ecosystem weakening its stability.”

(Beyond Pesticides, February 11, 2021) California sea lions (Zalophus californianus) are experiencing high rates of urogenital carcinoma (UGC) cancer incidences from the combined effect of toxic “legacy” pesticides like DDT and the viral infection Otarine herpesvirus-1 (OtHV1), according to a new study published in Frontiers in Marine Science. Previous research documents the role herpesvirus infection, genotype, and organochlorine pesticides play in sea lion cancer development. However, synergism (collaboration) between viral infection and toxic chemical exposure increases cancer development odds.
“This study has implications for human health, as virally associated cancer occurs in humans, and likelihood of cancer development could similarly be increased by exposure to environmental contaminants. Efforts to prevent ecosystem contamination with persistent organic pollutants must be improved to protect both wildlife and human health.”

Herbicide Use in “Regenerative” No-Till Contaminates Waterbodies
US study. (Beyond Pesticides, February 19, 2021) 'Tackling any one problem without precautionary attention to potential consequences of a solution — before it is enacted — is the opposite of the holistic understandings and strategies needed to solve environmental crises. Piecemeal approaches often generate unintended consequences. To wit: Vermont Public Radio (VPR) reports on revelations from a retired state scientist, Nat Shambaugh, who finds that farmers’ efforts to reduce agricultural runoff from fields into waterbodies, by planting cover crops, has resulted in significant increases in the use of herbicides to kill off those crops.'

Eliminating Pesticides Increases Crop Yields, Debunking Myth of Pesticide Benefits
(Beyond Pesticides, February 12, 2021) Recent research points to an example of such ecosystem efficacy. The study, by researchers in California and China, sought to evaluate whether increased population densities of fungi might be suppressing nematode populations in California production fields frequently planted with the cole crops (such as brussels sprouts and broccoli) they favor. The research finds that a diverse population of fungi in soils is highly likely to be effectively killing nematodes that threaten such crops.
These research results demonstrate how faulty the use of fungicides — which in 2012 amounted to 105 million pounds in the U.S — is likely to be. These compounds destroy fungi that provide a variety of beneficial and economically valuable ecosystem (and crop) services. Fungi decompose and recycle nutrients, improve moisture retention, and even act as biological controls for some fungal diseases. Many other pesticides, including glyphosate (which is an antibiotic) threaten microbial life, as well.

Glyphosate and Other Weed Killers Create Antibiotic Resistant Bacteria in Agricultural Soils
(Beyond Pesticides, February 24, 2021) 'Soil sprayed with weedkillers glyphosate, glufosinate, or dicamba are likely to contain higher amounts of antibiotic resistant bacteria, according to research published earlier this month in the journal Molecular Biology and Evolution. Each year in the United States, at least 2 million people develop an antibiotic resistant infection, and over 23,000 die. Authors of the study say widespread herbicide use is likely playing a role. “Our results suggest that the use of herbicides could indirectly drive antibiotic resistance evolution in agricultural soil microbiomes, which are repeatedly exposed to herbicides during weed control,” said Ville Friman, PhD of the University of York in the United Kingdom.
Contrary to the pesticide industry’s claim that these chemicals break down quickly and become inert by binding to soil particles, large proportions of the herbicides remained in the soil at the end of the 60-day experiment, stemming back from the first application. For glyphosate 18% remained, glufosinate 21%, and dicamba 34%.
... scientists determined that herbicide exposure triggers evolutionary pressures on bacteria similar to those exposed to antibiotics.
“Interestingly, antibiotic resistance genes were favoured at herbicide concentrations that were not lethal to bacteria,” said Dr. Friman. “This shows that already very low levels of herbicides could significantly change the genetic composition of soil bacterial populations. Such effects are currently missed by ecotoxicological risk assessments, which do not consider evolutionary consequences of prolonged chemical application at the level of microbial communities.”'

Ethanol Plant Processing Pesticide Coated Seeds Contaminates Nebraska Town

Ethanol Plant Processing Pesticide Coated Seeds Contaminates Nebraska Town
US info. (Beyond Pesticides, January 13, 2021) Under FIFRA (the Federal Insecticide Fungicide and Rodenticide Act), a clause known as the “treated article exemption” permits seeds to be coated with highly toxic pesticides without any requirement for the U.S. Environmental Protection Agency (EPA) to assess environmental or public health effects of their use.This allows hazardous pesticides (primarily insecticides and fungicides) to be used indiscriminately with no effective oversight. Research finds that over 150 million acres of farmland are planted with toxic seeds, including nearly four tons of bee-killing neonicotinoids each year.
The AltEn plant is unique in that it is accepting unused treated seeds for farmers, advertising the site as a “recycling” facility, according to The Guardian. Apart from biofuel production, ethanol plants usually sell their spent, fermented grains to livestock farmers for feed. Processing toxic seeds has made that product too hazardous for cattle, so AltEn has been selling it to farmers as a soil amendment.
The neonicotinoid clothianidin was found in a waste mound at an astounding 427,000 parts per billion (ppb). A wastewater storage pond found high levels of three neonicotinoids – imidacloprid, cloathianidin, and thimethoxam. Thiamethoxam was discovered at 24,000 ppb, over 300 times higher than its acceptable level in drinking water (70ppb), and roughly 1,300 times higher than the level considered safe for aquatic organisms by EPA (17.5ppb).
Expectedly, pollinators near the plant are dying off. Judy Wu-Smart, PhD, bee researcher at University of Nebraska documented a sustained collapse of every beehive used by the university for a research project on a farm within a mile of the AltEn plant.
SNAP Comment: SK apparently has two ethanol plants with several more in Canada. I hope we donot make the same mistake under the idea of recycling. Why not? Because we did it about treated wood, allowing it to be used or burnt in an unsafe manner under the guise of 'recycling" and 'reusing.' Let's face it,some products are just too toxic for tha

EPA Confirms Widespread PFAS Contamination of Pesticides, Announces “Investigation,” Stops Short of Action to Protect Public
(Beyond Pesticides, January 20, 2021) The U.S. Environmental Protection Agency has confirmed that PFAS (per and polyfluorinated alykyl substances) ‘forever chemicals’ are contaminating containers that store pesticide products, and subsequently the products themselves.
According to EPA, high-density polyethylene (HDPE) containers used to store and transport pesticides are commonly treated with fluoride in order to create a “chemical barrier” that will “prevent changes in chemical composition.” The fluorinated container is supposed to be more stable, and “less permeable, reactive, and dissolvable.”
Testing so far has been limited to one pesticide product supplier (likely the company Clarke, maker of Anvil 10+10), but resulted in detection of 9 different PFAS chemicals at levels the agency has not yet released. Earlier testing found PFAS chemicals well above safety limits established by states, as well as EPA’s health advisory. There are also indications that fluorinated HDPE containers may have other storage uses, such as food packaging. EPA announced that it is subpoenaing the company that fluorinates HDPE containers under the Toxic Substances Control Act, but has done little else from a regulatory standpoint. Contamination of widely used storage and transportation containers with chemicals that have been linked to cancer, liver damage, birth and developmental problems, reduced fertility, and asthma is a scandal without compare. It is unclear how long such a practice has been commonplace without any regulatory oversight.

Alternatives to CCA-Treated Wood
Alternatives to CCA-Treated Wood (PANNA Green Resource Center)
'Pressure-treated lumber is used in applications where decay and insect damage are of concern, such as for playground equipment, decks, telephone poles, building foundations, picnic tables, landscaping ties, wharfs, retaining walls, and fence posts. Preservative treatment chemicals make the wood inedible for fungi, insects, and other organisms that can destroy wood. Until its use for residential applications was voluntarily restricted by industry in January 2004, copper chromated arsenate (CCA) was the most common wood preservation treatment that a typical homeowner would encounter.' (same timeline in Canada)
Rubbing a cloth on the CCA treated wood in a playground collected toxic levels of arsenic and chromium.
When arsenic treated wood is new, it tends to have a greenish tint. When CCA wood is older, it is harder to tell.

Study Finds Link Between Pesticide Exposure and Rare Blood Cancer Predecessor (MGUS)
Study Finds Link Between Pesticide Exposure and Rare Blood Cancer Predecessor (MGUS)
(Beyond Pesticide, January 14, 2021) Long-term exposure to permethrin and legacy organochlorine pesticides (aldrin, dieldrin, and lindane) increase the risk of developing monoclonal gammopathy of undetermined significance (MGUS), a blood disease that likely precedes multiple myeloma (MM)—a type of blood cancer, This study highlights the importance of understanding how pesticide use can increase the risk of latent diseases, which do not readily develop upon initial exposure. Study researchers state, “Our findings provide important insights regarding exposures to specific pesticides that may contribute to the excess of MM among farmers.
The presence of abnormal proteins (monoclonal M protein) in the blood within bone marrow is a characterization of monoclonal gammopathy of undetermined significance. Although MGUS is benign (non-cancerous) and largely asymptomatic, it can be premalignant or a precursor for cancer development. Annually, one percent of individuals with MGUS will develop cancers like multiple myeloma, lymphoma, or amyloidosis. However, the cancer risk increases in people whose protein levels are abnormally high, which can occur upon repeated exposure to endocrine-disrupting chemicals, like pesticides. Moreover, multiple myeloma is a rare type of blood cancer of the plasma cells, killing nearly 40 percent of 32,270 people it afflicts in the U.S. annually.

Genetically Weakened Skin Barrier Allows for Easier Absorption of Toxic Chemicals
Genetically Weakened Skin Barrier Allows for Easier Absorption of Toxic Chemicals
Genetically Weakened Skin Barrier Allows for Easier Absorption of Toxic Chemicals (Beyond Pesticides, January 21, 2021) (I)ndividuals with genetically weakened skin barrier protection experience higher rates of toxic chemicals (i.e., pesticides) absorption through the skin. Studies provide evidence that filaggrin genetic mutations can exacerbate the impacts of chemicals upon dermal (skin) exposure, causing various skin diseases like dermatitis and other chemical-related effects like asthma and cancer. Filaggrin is a protein that is critical to skin cell structure or epidermal homeostasis. Dermal exposure is the most common pesticide exposure routes, compromising 95 percent of all pesticide exposure incidents. Furthermore, many pesticides contain chemicals that act as sensitizers (allergens). Therefore, it is essential to mitigate direct skin contact with these toxic chemicals and enforce proper application protocol. Researchers find that pesticide levels are two times higher in individuals with FLG null mutations. Therefore, increased chemical absorption can have implications for human health. FLG null mutations are relatively common, especially among people of European descent.

Long-Term Roundup Exposure Found to Harm Keystone Wildlife Species
Long-Term Roundup Exposure Found to Harm Keystone Wildlife Species
(Beyond Pesticides, January 6, 2021) “The problem is that much of the evidence is rooted in outdated toxicity tests which only look at the number of animals that die on exposure to extremely high concentrations of these chemicals,” Dr. Orsini said. “These tests also overlook the pathological effects arising from long-term exposure to low doses. What we’re proposing is that toxicity is measured by looking at what happens to the animal at a molecular and fitness level following long-term exposure, which encompasses the entire animal life cycle.”
Changes in fitness were seen for every trait except mortality. Roundup delayed average age of sexual/reproductive maturity, reduced size at maturity, decreased the total number of offspring produced, and increased developmental failure – as determined by the number of aborted eggs, and juveniles borne dead.. Researchers also observed damage to DNA, with glyphosate and Roundup showing only slight differences in affected pathways Roundup and glyphosate were also found to indirectly alter both the makeup and total number of microbiota in the water flea’s gut. These changes were correlated with alterations to the way fat and carbon are metabolized, as well as the animal’s detoxification pathways.

Pesticides and Road Salt: A Toxic Mixture for Aquatic Communities
Pesticides and Road Salt: A Toxic Mixture for Aquatic Communities
(Beyond Pesticides, January 7, 2021) Insecticides and road salts adversely interact to alter aquatic ecosystems, reducing organism abundance and size, according to a study in the journal Environmental Pollution. Pesticide use is ubiquitous, and contamination in rivers and streams is historically commonplace, containing at least one or more different chemicals.
Researchers performed a toxicity evaluation of six insecticides from three chemical classes (neonicotinoids: thiamethoxam, imidacloprid; organophosphates: chlorpyrifos, malathion; pyrethroids: cypermethrin, permethrin). Additionally, researchers note the potentially interactive effects of these insecticides with three concentrations of road salt (NaCl). Researchers find that differing pesticide classes directly impact aquatic communities, and exposure to insecticides indirectly alters the food web in freshwater communities. Although pesticides and road salts individually impact aquatic communities, this study is the first to demonstrate their interactive effects.

New Test Will Help Researchers Understand Pesticide Threats to Wild Bat Populations
New Test Will Help Researchers Understand Pesticide Threats to Wild Bat Populations
(Beyond Pesticides, December 10, 2020) 'A new test developed by a team of Mexican and Canadian scientists will help field researchers detect early warning signs of pesticide exposure in wild bat populations.
The test in question is referred to as a micronucleus test. Although it does not measure the level of pesticide contaminating a bat’s body, it can assess genotoxicity (the effect of pesticides and other chemical agents that damage genetic information in a cell). This is done by taking blood samples of bats, and testing for the presence of micronuclei formation, which are materials in blood that contain damaged chromosomes not incorporated into a cell after cell division.
What little research that has been conducted on the harm pesticides cause to bats shows significant cause for concern. Agricultural pesticide use results in a large proportion of a bat’s insect diet being contaminated with highly toxic chemicals. Bats are particularly sensitive to pesticides that bioconcentrate in fat (lipophilic pesticides); they develop large stores to use while migrating or hibernating, and high concentrations of toxic pesticides in this fat can result in significant poisoning as the body burns it off. Despite the unique ways in which pesticides harm bats, the U.S. Environmental Protection Agency (EPA) does not evaluate a pesticide’s effect on bats prior to registration. Because bats are unusually long-lived for animals their size — lifespans range from 20 to 40 years — their bodies can accumulate pesticide residues over a long period, exacerbating adverse effects associated with those pesticides that can accumulate in fatty tissue.' A bat's 'consumption of large volumes of pesticide-contaminated insects can mean that these compounds may reach toxic levels in their brains — making them more susceptible to White Nose Syndrome.'.

What’s Bad for Bees Could Be Bad for Marine Life, Too Preliminary research shows that a popular insecticide hampers arthropods in the ocean. (by Ramin Skibba, PANNA, May 4, 2020)
'They found that coral exposed to the insecticide had reduced polyp activity—an indication of increased stress. Shrimplike amphipods were affected, too. Even at low doses, imidacloprid exposure inhibited their movement. And for some, high levels of exposure were fatal.
Hladik says most of the concentrations of neonics tested in Davis’s experiment were unrealistically high—beyond what is seen in the wild. But even low doses, she adds, could still be a hazard for marine life.'
