Slugs and Snails Controlled with Bread Dough, Really

(Beyond Pesticides, August 25, 2021) 

Slugs and snails overwhelmingly chose to feed on the bread dough baited traps....Although researchers used toxic metaldehyde to kill slugs when they got to the bait, discretely located traps can ensure that a pesticide is not used in a broadcast manner and disposed of properly. However, many traps and baits, such as the Snailer, will work with bread dough and water without the need for additional pesticide, as they bar pests from exiting and cause the slug or snail to drown.'

Organochlorine Pesticides among South China Sea Coral Reefs

(Beyond Pesticides, August 12, 2021) A recent study published in Chemosphere identifies the concentration, consequences, and potential sources of 22 organochlorine pesticides (OCPs) among corals in the South China Sea (SCS) for the first time. SCS corals exhibit a higher affinity toward bioaccumulation of OCPs, which are legacy persistent organic pollutants (POPs) under the Stockholm Convention—a global treaty to eliminate POPs. The study finds the distribution of OCPs in coral tissue matches that of the surrounding oceanic air samples.... Long-range atmospheric transport and condensation are significant contributors to the global contamination of environmental pollutants like OCPs.

Of Multiple Stressors, Pesticides Are the Most Harmful to Bees by Acting Synergistically to Increase Mortality

(Beyond Pesticides, August 11, 2021) Multiple stressors, including pesticides, parasites, and poor nutrition, act synergistically to increase the risk of bee mortality, according to a meta-analysis recently published in the journal Nature. The findings are yet another indictment of the U.S. pesticide regulatory system’s ability to protect pollinators, as the authors note that their results, “…demonstrate that the regulatory process in its current form does not protect bees from the unwanted consequences of complex agrochemical exposure.”

At the most general level, multiple stressors were synergistic in the context of bee mortality, but additive for effects on overall fitness. Looking further into the data, it was determined that exposure to multiple pesticides had the most robust connection to synergistic impacts.

Global Review Identifies Key Drivers of Pollinator Decline, Threat for Humanity

Global Review Identifies Key Drivers of Pollinator Decline, Threat for Humanity

(Beyond Pesticides, August 17, 2021)  'Overall, land cover, land management, and pesticide use are identified as ‘very important’ or ‘important’ drivers of pollinator declines in nearly every geographic region of the world. While climate change is also identified as such, experts do not have as much confidence in its importance when compared to other factors putting pollinators at risk. Pests and pathogens are identified as very important risks in North America and Latin America, and generally rank above concerns over pollinator management and invasive species. Genetically engineered cropping systems are identified as a lower threat in most regions of the world, but very important threat in Latin America, where hazards are identified due to high use of glyphosate resistant crops and subsequent data on the dangers of that chemical to pollinators.'

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.'

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, May 20, 2021) Beyond Pesticides and Friends of the Earth (FOE) collaborated to analyze herbicide products at two of the most popular home and garden retailers, Home Depot and Lowe’s. 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

(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.'

Throughout the southeastern United States, bald eagles and other top-level avian predators were experiencing mass deaths from a disease known as vacuolar myelinopathy (VM), a neurological ailment that causes lesions in affected animal’s brains. Now, scientists have determined that the chemical bromine, likely introduced by brominated herbicides in attempts to manage the invasive species, is the trigger for the production of the cyanobacteria’s neurotoxin... Most sources of bromine in a freshwater ecosystem are likely to be added by humans.

The use of a bromide-based product, intended to kill a plant that harbors a bacterium that, in the presence of bromine, produces a lethal neurotoxin is far beyond the scope of any risk assessment conducted by pesticide regulatory agencies.'

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. The area was designated a federal superfund site because of the contamination.'

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.

Meta-Review: Pesticides Kill or Harm Soil Invertebrates Essential to Soil Health  (Beyond Pesticides, May 7, 2021) 

'A recent meta-review of nearly 400 studies finds that, in 71% of the cases reviewed, pesticides kill or otherwise harm soil invertebrates that contribute mightily to soil health. 

 In some cases, the organisms that are the most extensively studied are known to be less sensitive to pesticides than other organisms, suggesting that we have limited knowledge of the extent of harm caused by pesticides.”

Research Shows Adverse Impacts of Glyphosate on the Human Gut Microbiome

(Beyond Pesticides, April 30, 2021) A bioinformatics tool developed by researchers from the University of Turku in Finland indicates that “54% of species in the core human gut microbiome are sensitive to glyphosate.” 

The researchers’ bioinformatic method categorizes EPSPS enzymes into four classes, each of which has a different sensitivity to glyphosate, with one of the four classes being particularly vulnerable.  In addition, the co-authors suggest that glyphosate may impact other metabolic pathways (beyond the Shikimate), positing that the mitochondria electron transport chain appears sensitive to the compound.

Study Finds Eagle Populations Experiencing Widespread Rodenticide Exposure

(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. 

The second-generation anticoagulant rodenticide brodifacoum was the most detected compound in sampled eagles.

SFM’s President Mary Lou McDonald, an environmental lawyer, commented:

PMRA’s environmental risk assessment on the chemical did not use proper methods of science, and PMRA was late to the party in seeing the dangerous health effects. This is not protecting Canadians from the risks of pesticides. 

Health Canada needs its own and better resources to properly assess risks, instead of relying on the assumptions and science fed to it by corporations and then relying on NGOs to tell them where they are wrong. The current system isn’t working.”

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.'

Toxic Pesticides Are Polluting Over Half of Arable Land, Reinforcing Need for Global Organic Transition

(Beyond Pesticides, April 7, 2021) 'Toxic pesticides are putting more than half of the Earth’s farmland at risk of pesticide pollution that contaminates water, harms biodiversity, and ultimately undermines food security, according to research published in Nature Geosciences last month.   A pesticide was deemed to put a location at risk if the predicted environmental concentration of the pesticide was expected to be above the no-effect concentration for ecotoxicological harm. The high risk designation was noted when expected environmental concentrations were more than three orders of magnitude (1,000x) higher than the no-effect concentration.     Scientists determined that 75% of global agricultural land was at risk, with 31% at high risk. Considering the additive effects of pesticide use, researchers found that 64% of ag land was at risk from more than one of the 92 pesticide active ingredients evaluated. Shockingly, 21% of farmland is at risk by more than 10 pesticides.'

Invertebrates and Plants Face Increasing Threat from Pesticide Use, Despite Declining Chemical Use Patterns

Pesticide use threatens aquatic and terrestrial invertebrates and plants more than ever, despite declining chemical use and implementation of genetically engineered (GE) crops in the U.S., according to a University Koblenz-Landau, Germany study.' Although the new generation of pesticides (e.g., neonicotinoids, pyrethroids) pesticides are more target-specific, requiring lower chemical concentrations for effectiveness, they have over double the toxic effects on invertebrates, like pollinators....'The study results find a decrease in total pesticide amounts by volume on U.S. farms by 40 percent over the last 25 years. Although bird and mammal toxicity decreases with a reduction in pesticide use (95 percent), invertebrates experience higher toxicity levels. Pyrethroid insecticides cause toxicity to double among aquatic invertebrates. Neonicotinoid insecticides present double the risk to terrestrial invertebrates. Overall, pesticide toxicity for terrestrial plants is highest regardless of whether fields are conventional, non-GE, or GE

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-methyltriforine, and kresoxim-methyl increased risk of tumor development. Medulloblastoma was associated with the use of chlorothalonilpropiconazoledimethoate, 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!

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.'.

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.

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.

Ecosystem Health: Pesticide Use from Forest Management Practices Threatens Essential West Coast Marine Organisms

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 tissuesIndaziflam (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.

(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.'

SNAP Comment: There are 99 imidacloprid products registered in Canada as of 23 March 2021, many of them registered for pet treatments. Flumethrin is not and has not bee registered in Canada. The Seresto trademark is not registered in Canada.

PAN’s Bans List shows that 162 countries have banned a total of 460 pesticide active ingredients or groups of actives regarded as still ‘currently in use’ in the global market, i.e. not obsolete. In total, there were 94 active ingredients that were newly added to the list of banned pesticides. This includes the world’s most popular weedkiller, glyphosate. The list also shows that for the first time, imidacloprid, clothianidin and thiamethoxam – neonicotinoids linked to bee deaths – have all lost approval in the European Union (EU).

Solitary Wild Bees Harmed by Neonicotinoid Pesticides Applied by Soil Drenching

(Beyond Pesticides, March 2, 2021) 'Populations of solitary ground nesting bees decline after exposure to neonicotinoid insecticides, according to a study published in Scientific Reports late last month. In addition to ground-nesting bees, neonicotinoids have been shown to harm butterflies, hummingbirds, songbirds, aquatic species and mammals, including human,.. Squash seeds were treated with the neonicotinoid thiamethoxam, the neonicotinoid imidacloprid was applied as a soil drench, and chlorantraniliprole was sprayed on plant foliage. A fourth group of hoop houses did not have a pesticide applied in order to act as a control.

Results show that the soil drench (imidacloprid) presents significant hazards to ground nesting bees. Hoary squash bees in this group initiated 85% fewer nests, harvested 5 times less pollen, and produced 89% fewer offspring than the untreated control group... Whatever the etiology of the deleterious effects observed, study authors are certain that their data points to unacceptable hazards from the use of imidacloprid.'

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.”'

(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.”

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   (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.

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?

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.

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.

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.

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.'.
