SNAP Comment. First thoughts: What strikes me on this table is that there is no respiratory exposure considered, and that it adds to the dermal when one runs into spray unless one wears a mask. Of course, I knew that pesticides are not regularly tested for this route but I find it a glaring omission in international standards intended somewhat to protect health.
Also, p8, whether the toxicity of a single ingredient should be used to extrapolate toxicity of a formulation.
Considering that active ingredients are generally either water or fat soluble and that they need to be both to penetrate living cells, the formulants in a formulation are added to fill up that 'deficiency' and make the product both water and fat soluble so it can penetrate any living cell. That basic principle makes it impossible in my view to 'extrapolate' toxicity of a formulation from a single product.SNAP also recognizes that the data for formulations toxicity is often not available.

Robust Science on Transgenerational Health Effects Tied to Pesticide Exposure, Highlights Regulatory Gaps
Robust Science on Transgenerational Health Effects Tied to Pesticide Exposure, Highlights Regulatory Gaps (Beyond Pesticides, 5 June 2026)
...But reproduction is not the only domain affected. As the authors write, “The modified germline epigenome influences the epigenetic profiles of embryonic stem cells and will subsequently affect the epigenomes of all somatic cells in the next generations (emphasis added). This means that all tissues, not just reproductive organs, are influenced by that original exposure. In addition to ovarian, prostate, and testis pathologies, the researchers find sharp increases in kidney pathologies in both sexes between the first transgeneration and the 23rd. Sprague-Dawley rats are susceptible to kidney disease as they age, but these pathologies emerge at one year.
Dr. Skinner has also demonstrated epigenetic transgenerational effects of exposure to DDT, glyphosate, atrazine, dioxin, DEET, permethrin, methoxychlor, hydrocarbons and plastics-derived compounds.

Research in Ten European Countries Finds Pesticides Threaten Soil Health in Conventional and Organic Fields
Research in Ten European Countries Finds Pesticides Threaten Soil Health in Conventional and Organic Fields (Beyond Pesticides, 3 Septmber 2026)
The findings are published in Environmental Science and Pollution Research.
The study identifies measurable levels of numerous pesticides and mixtures of pesticides (including several fungicides, copper, and the glyphosate metabolite AMPA (aminomethylphosphonic acid) and their combined effect in adversely affecting soil microbiota, which “play a major role in ecosystem functioning,” according to the research team comprising scientific experts and state (national) agencies across the European Union.
Researchers show that organic and conventional fields both become exposed to pesticides, adversely affecting soil microbial life, including substances allowed in organic production—though far fewer than those allowed in conventional agriculture.
The findings support advocacy to stop pesticide use through a societal transition to organic practices...filed under Pesticides in soils p.2

Diflufenican breaks down into TFA and must be banned
Diflufenican breaks down into TFA and must be banned (PAN Europe, April 23, 2026)
The case against diflufenican is now clear-cut. This #herbicide, widely applied on winter cereals across Europe, breaks down into #TFA, an ultra-persistent "forever chemical" that is accumulating in groundwater and polluting our drinking water.
Evidence shows that the (European) legal threshold for groundwater is breached by diflufenican under real-use conditions. The European Commission must immediately propose its non-renewal in accordance with EU law.SNAP Comment:: diflufenican was first registered in Canada on 22 February 2024 for use in soybeans and corn.

Almost half of the world s farmers are poisoned by pesticides every year
Almost half of the world's farmers are poisoned by pesticides every year (PANNA, September 2, 2026)
A new study published in Frontiers in Public Health?shows that over 400 million of the world’s farmers and farmworkers suffer from acute pesticide poisoning annually. Acute pesticide poisoning is any illness or health effect experienced a short time after exposure (for example, within 48 hours) Total fatalities around the world from unintended pesticide poisonings are estimated at around 11,000 deaths per year. This total excludes the 84 million children working in global agriculture who are even more vulnerable to toxic chemicals than adults, as well as rural families exposed through spray drift and environmental exposure. Farmers may also consume highly contaminated food... Furthermore, personal protective equipment is frequently too costly and impractical in hot climates. This study only looked at acute poisonings, not long-term chronic effects which are harder to measure.

Dutch court: endocrine-disrupting pesticide needs to be banned
Dutch court: endocrine-disrupting pesticide needs to be banned (PAN europ, 12 August 2026)
The highest Dutch administrative court has ruled that the #pesticide formulation Pitcher containing the endocrine-disrupting substance fludioxonil needs to be banned as soon as possible. The verdict follows a landmark ruling from the EU Court of Justice in a case started by PAN Europe.
The Dutch court is very clear in its press release: “Pitcher contains an active substance (fludioxonil) that has endocrine-disrupting properties. Under European regulations, this active substance may only be used in closed systems or under other conditions that preclude contact with humans. As Pitcher is not used in this way, the Ctgb should not have authorised the product. The Ctgb must therefore ensure that Pitcher is withdrawn from the market as soon as possible.”SNAP comment: Fludioxonil: 51 (from 70) containing products currently registred in Canada. Used as a seed treatment, a foliar spray and a post-harvest dip to control fungal pathogens on a large number of crops. Endocrine disrupting, PFA, on the EU's more toxic pesticides list. Widely found on conventional strawberries in Europe. A quick check seems to indicate it i used for post-harvest potato and sweet potato treatment in Canada, but not registered for post-harvest strawberries.

EPA Promotes PFAS-Contaminated Sewage Sludge/Biosolids While Halting Regulatory Restrictions
US study
EPA Promotes PFAS-Contaminated Sewage Sludge/Biosolids While Halting Regulatory Restrictions
(Beyond Pesticides, August 3, 2026) A regulation proposed by the U.S. Environmental Protection Agency (EPA), with a comment period ending September 4, 2026, will allow sewage sludge, also called biosolids, fertilizer used in agriculture and other land management to contain PFAS (per- and polyfluoroalkyl substances).
Contaminants in sewage sludge/biosolids have been widely recognized for decades, leading to regulations.The lawsuits against producers of sewage sludge fertilizer cite test results showing PFAS residues in the companies’ products and numerous scientific studies on the adverse effects of PFAS to public health, wildlife, and pollinators. EPA has published a list of 726 chemicals found in biosolids in the National Sewage Sludge Surveys (2022). This list does not include PFAS, which are emerging contaminants of biosolids although they publicly disclosed findings of PFAS in sewage sludge/biosolids in 2001 with the release of the agency’s National Sewage Sludge Survey.

Aquatic Ecosystems at Risk; Study Finds Declines in Macroinvertebrate Diversity with Pesticide Exposure
Chinese study
(Beyond Pesticides, July 22, 2026) ( Chinese Study) A study of aquatic macroinvertebrates, including insects in their nymph and larval stages, snails, worms, crayfish, and clams, finds that pesticide exposure leads to biodiversity declines. Published in Environment International, this research also finds that multiple stressors and chemical mixtures increase ecosystem effects.
Water samples were then analyzed for 49 commonly used and representative pesticides, including carbamates (CAs), neonicotinoids (NEOs), triazines (TRIs), and organophosphates (OPPs), and macroinvertebrates were identified. The results show that all “49 pesticides were detected, including 11 CAs, 9 NEOs, 14 OPPs, and 15 TRIs.”
Imidacloprid has the highest ecological risk level across both hydrological seasons.(dry and normal) Hexazinone, atrazine, and simazine also exhibit high risks, as they share a common mode of action by inhibiting “primary producers and thereby indirectly affecting food resources and oxygen supply for higher trophic levels, including macroinvertebrates.”
Simazine “may exert disproportionately strong ecological pressure relative to its measured concentrations.”SNAP Comment: There ar 94 Imidacloprid, 5 Hexazinone, 17 atrazine, and 4 simazine containing pesticide productscurrently registerd in Canada.
