(Beyond Pesticides, December 24, 2024 – January 1, 2025) We wish you a healthy and happy holiday season! The health and environmental challenges that we face as families and communities across the nation and worldwide require us to stay engaged. The stark reality of the challenges ahead energizes us at Beyond Pesticides to strengthen our program—now, more than ever!   And, we trust that you, like us, want to push forward for a livable future. In this context, please see our annual report and summary on the important work that we are doing, and please consider a contribution to Beyond Pesticides during this holiday season.  While the threats of health, biodiversity, and climate crises grow exponentially, the solutions we have advocated for decades are now within reach. We know how to produce food and manage land without petrochemical pesticides and fertilizers, as organic food is widely available. Beautiful parks, playing fields, and schoolyards do not require toxic chemical use. At the same time, the regulatory system underperforms, as existential health and environmental problems escalate.   And, we know that individual steps that we take to stay healthy, as important as they are, cannot protect us and the natural world, on which […]

(Beyond Pesticides, December 23, 2024) As the U.S. Fish and Wildlife Services (FWS) proposes to list the Monarch butterfly as a threatened species under the Endangered Species Act, a look at the factors contributing to the butterfly’s catastrophic decline includes a stunning failure of the U.S. Environmental Protection Agency’s (EPA) regulation of pesticides to protect biodiversity and the ecosystems necessary to its survival. While there are many factors affecting the survival of Monarchs, EPA’s Office of Pesticide Programs (OPP) has allowed pesticide use to continue unabated, with only rhetorical attention to the problem. Meanwhile, the science shows a range of pesticide effects associated with insecticides and herbicides. A study published in PLOS One in June identifies insecticides as the primary driver in butterfly’s decline, as EPA points, almost exclusively to herbicide use and the destruction of Monarchs’ food source, milkweed habitat. While two or several factors can be true at the same time, EPA has failed to consider the confluence of factors, including the impacts of climate, as rising temperatures are exacerbated by the production and use of petrochemical pesticides. FWS is stepping in at a critical time with looming biodiversity collapse and in the absence of EPA taking the reins […]

Image: Art Page submission from Carol Moyer, “Monarch Butterfly Sideways with Closed Wings.“ (Beyond Pesticides, December 20, 2024) On December 12, the U.S. Fish and Wildlife Service (FWS) opened a public comment period on its proposal to list the monarch butterfly (Danaus plexippus) as a threatened species and to designate critical habitats for the species under the Endangered Species Act of 1973. Under the proposal, the designated habitats would span approximately 4,395 acres throughout overwintering sites in coastal California. The public comment period will be open until March 12, 2025. These suggested protections call attention to the role of chemical-intensive agriculture in affecting populations of pollinators and other beneficial organisms. George Kimbrell, legal director at the Center for Food Safety, shares in a press release that the “monarch listing decision is a landmark victory 10 years in the making. It is also a damning precedent, revealing the driving role of pesticides and industrial agriculture in the ongoing extinction crisis… But the job isn’t done: Monarchs still face an onslaught of pesticides. The Service must do what science and the law require and promptly finalize protection for monarchs.” In the docket, FWS states, “Under the Act, a species warrants listing if […]

(Beyond Pesticides, December 13, 2024) In October, the U.S. Environmental Protection Agency (EPA) approved the registration applications of BASF Corporation and Mitsui Chemicals Crop & Life Solutions, Inc. for the use of different formulations of the L-isomer of glufosinate (also known as “L-glufosinate” and “glufosinate-P”) as new active herbicidal ingredients. This decision marks one of the first times that EPA has employed its new Herbicide  Strategy Framework to determine the level of mitigation necessary to protect listed species and critical habitat under the Endangered Species Act (ESA). Glufosinate is an organophosphate, with known neurotoxic, reproductive/developmental effects, toxic to aquatic life, and mobile in soils (see Beyond Pesticides Gateway). Scientists have found that formulated glufosinate is generally more toxic to aquatic and terrestrial animals than the technical grade active ingredient. Manufacturers are introducing newer glufosinate products as alternatives for glyphosate-based herbicides, like Bayer/Monsanto’s ‘Roundup’ and dicamba. The Center for Biological Diversity notes in comments submitted to EPA on this decision, “L-glufosinate has the potential to be used on tens of millions acres of land every year given the crops EPA has proposed to register it on. The scale of potential use is far above most new active ingredients.” This first significant application […]

(Beyond Pesticides, December 12, 2024) A literature review of 161 articles in Discover Toxicology finds that pesticides with different mechanisms of action cause memory and learning impairments. These effects are noted in nontarget species including humans. Pesticide “[e]xposure during development, as well as chronic environmental and occupational exposure, can contribute to decreased cognitive performance,” the researchers say. With a focus on organophosphate pesticides, synthetic pyrethroids, and neonicotinoid insecticides, the authors highlight neurological impacts. Both learning and memory are crucial for the survival of many species. “Considering the importance of learning and memory for human and non-human animal behavior and the growing association between pesticide exposure and cognitive impairment, the aim of this review was to describe the studies showing the impact of pesticide exposure on memory and learning abilities in nontarget species, providing evidence of the impact of pesticides in central nervous system function,” the researchers state. The 161 articles included in the review were identified through database searches in PubMed/Medline and Scielo. The authors note, “Inclusion criteria for article selection included all articles published in English between 2015 and 2024 containing original studies in animals or humans with single or multiple pesticides exposure.” The articles consist of 132 preclinical […]

(Beyond Pesticides, December 10, 2024) Scientists from the Engineering Research Center of Protection and Utilization of Plant Resources at Shenyang Agricultural University in China reveal adverse effects of imidacloprid on soil communities in a study published in Pesticide Biochemistry and Physiology. The researchers highlight risks to nematodes from imidacloprid exposure in maize soil, as well as potential resistance mechanisms that impact not only nematode populations but also overall soil health. Maize, or corn, a productive crop grown worldwide, is a source of food and biofuel. In assessing the soil and species in maize fields after exposure to imidacloprid at various concentrations, the study researchers assess the impact of neonicotinoid insecticides on nontarget organisms and the health of soil communities. The assessment includes an evaluation of nematodes’ survival, growth, reproduction, and chemotaxis/locomotion behavior. With a statistical analysis of lipid and lipofuscin accumulation, acetylcholinesterase (an enzyme necessary for neurotransmission) activity, and gene expression levels, the study results show that imidacloprid induces: significantly reduced abundance and diversity of nematode species. negative effects on body length, reproduction, locomotion, lipid accumulation, lipofuscin accumulation, and acetylcholinesterase activity in Caenorhabditis elegans ( elegans). the upregulation of gpa-1, cyp-35a2, fat-2, fat-6, hsp-16.41, and hsp-16.2, along with the downregulation […]

(Beyond Pesticides, December 5, 2024) A novel, comprehensive study published in Science reviews a library of 1,024 different chemicals (herbicides, insecticides, fungicides, and plant inhibitors) finding that, even at “sublethal” exposure levels, 57% of tested chemicals impact the behavioral and physiological health of house fly larvae. Mosquito and butterfly populations are also susceptible to long-term adverse effects at sublethal levels. Environmental and public health advocates continue to raise concerns about adverse effects resulting from the failure of the U.S. Environmental Protection Agency (EPA) to consider cumulative exposure (resulting in aggregate and synergistic effects) across different mechanisms of toxicity and different classes of pesticides, including at exposure levels below allowable levels set by the agency. In the context of the regulatory gaps and pesticide industry influence at EPA (See Daily News here), advocates stress the importance of transitioning land and agricultural practices to organic principles. Methodology and Results  Background, Goals, Primary Takeaways  This research was led by an international team of experts from various universities and institutes, including European Molecular Biology Laboratory (EMBL), Institut Pasteur, and Heidelberg University (Center for Infectious Diseases, Parasitology Department). The authors received funding from the European Molecular Biology Laboratory, the German Center for Infection Research, and […]

(Beyond Pesticides, December 3, 2024) In an article in Science, Sabrina Rondeau, PhD reviews her research from 2022-2024 showcasing species of ground-nesting bees, often found in crop fields, that are highly vulnerable to soil pesticide residues and subsequently suffer population declines. Dr. Rondeau, a postdoctoral fellow in the Department of Biology at the University of Ottawa, points to regulatory deficiencies, specifically in environmental risk assessments (ERAs), and the detrimental effects of pesticides on pollinators that threaten food security and biodiversity. “Modern intensive agriculture faces a critical paradox: The very pesticides designed to protect our crops endanger essential pollinators that sustain their productivity,” Dr. Rondeau says in the article. Her research (see here, here, here, here, here, and here) identifies important gaps overlooked in current assessments and regulations for bee species, including the common eastern bumble bee (Bombus impatiens) and the hoary squash bee (Xenoglossa pruinosa). Bumble bee queens in temperate climates hibernate for 6-9 months in the soil, while the hoary squash bee is a solitary ground-nesting species. Reference additional Daily News coverage on ground-nesting bees here and here. “‘Our findings show that over 70% of wild bee species, which are crucial for pollinating our food crops, face significant risks […]

(Beyond Pesticides, November 6, 2024) An analysis in the International Journal of Research Publication and Reviews emphasizes the role of biodiversity in agriculture, adding to a wide body of science on its importance. The authors, from Western Illinois University in the United States and Rome Business School in Italy, find that biodiversity supports critical ecosystems and organisms needed for sustainable food production. Through literature reviews and case studies, the interconnectedness of agriculture with plant and animal diversity, beneficial insects, soil health, and climate change is highlighted, as well as the need to manage land organically to support biodiversity. Plant and Animal Diversity As the researchers note, “A diverse agricultural system can better absorb shocks and maintain productivity, ensuring food security in the face of uncertainty.” A wide range of species present within ecosystems protects from changing environmental conditions and improves resilience. When farmers use monocultures for their crops, this leads to reduced ecosystem services from beneficial insects and increased vulnerability to pests and diseases. “By contrast, diverse cropping systems can enhance resilience, providing a buffer against environmental changes and fostering sustainable food production,” the authors say. Research shows that higher plant diversity disrupts pest life cycles and promotes beneficial insects, […]

(Beyond Pesticides, October 30, 2024) STARTS TODAY at 2 PM EDT—NATIONAL FORUM: IMPERATIVES FOR A SUSTAINABLE FUTURE. Beyond Pesticides has filed suit against The Scotts Miracle-Gro Company and GreenTechnologies, LLC for allegedly misleading consumers on the hazardous nature of their fertilizer products, which contain sewage sludge (often referred to as biosolids) contaminated with per- and polyfluoroalkyl substances (PFAS). The group filed two cases, Beyond Pesticides v. Miracle-Gro Co. and Beyond Pesticides v. GreenTechnologies, LLC, in D.C. Superior Court on October 25, 2024. The complaint alleges that, as part of their marketing, these companies tell consumers that their fertilizers are “eco-friendly” and “sustainable,” when, in fact, the products contain hazardous substances. The complaint cites test results showing PFAS residues in the companies’ fertilizers and numerous scientific studies on the adverse effects of PFAS to public health, wildlife, and pollinators.   PFAS, known as “forever chemicals” due to their ability to persist in the environment, are endocrine disruptors linked to developmental issues, cancers, metabolic, cardiovascular and reproductive harm, damage to the liver, kidneys, and the respiratory system, as well increased chances of disease infection and severity. The chemicals’ immunotoxic effects threaten human health.  Beyond Pesticides alleges that consumers are, thus, misled by advertising in which Scotts Miracle-Gro […]

(Beyond Pesticides, October 25, 2024) To better understand synergistic interactions between multiple stressors, researchers from the Helmholtz Centre for Environmental Research in Leipzig, Germany, analyze exposure to the pyrethroid insecticide esfenvalerate with two nonchemical environmental factors: elevated temperature and food limitation. In their recent publication in Environmental Pollution, the authors find the greatest synergistic effects when Daphnia magna (D. magna) are subjected to esfenvalerate under conditions experienced with climate change including lower food availability and increased temperature. D. magna, also known as daphnids or water fleas, are small planktonic crustaceans that represent an essential part of the food web in lakes and ponds. Impacts on populations of daphnids can lead to effects throughout multiple trophic levels that impact overall biodiversity. As the researchers state, “Global biodiversity is declining at an unprecedented rate in response to multiple environmental stressors… A key challenge is understanding synergistic interactions between multiple stressors and predicting their combined effects.” To study this, a Stress Addition Model (SAM), which predicts the cumulative effects of interacting stressors, was utilized and compared to laboratory data using 24-hour-old neonates of D. magna. The organisms were subjected to various conditions, singularly and in combination, including increased temperature, lower quantities of food, […]

(Beyond Pesticides, October 24, 2024) When U.S. Senator Cory Booker (D-NJ) introduced S. 5084, Safe School Meals Act (SSMA) in September, he identified four objectives: Directing the Food and Drug Administration (FDA) to set safe limits for heavy metals in school meals. The limits will be based on a threshold of reasonable certainty of no harm to school-age children from aggregate exposure. If the agencies fail to set these limits within two years, the limits will automatically be set to non-detectable until the agencies can determine a safe level of exposure. Banning glyphosate, paraquat, and organophosphate pesticide residues in school meals. Certified organic farms would automatically meet this requirement. Banning PFAS, phthalates, lead, and bisphenols in food packaging in school meals. Directing FDA to reevaluate food additives with known carcinogenic, reproductive, or developmental health harms, such as artificial food dyes, and ban their use in school meals prior to the completion of FDA’s analysis. While groups like Beyond Pesticides applaud Senator Booker’s initiative to restrict exposure to some of the most hazardous toxicants, especially the most vulnerable subpopulation of children, their goal is to provide organic food to school children. In this spirit, groups have advocated that the U.S. Department […]

Beyond Pesticides (October 17, 2024) On September 30, 2024, the U.S. Environmental Protection Agency (EPA) opened a public comment period about production of specific per- and polyfluoroalkyl substances (PFAS, also known as ‘forever chemicals’)—including perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA). EPA is collecting information on the fluorination process of high-density polyethylene (HDPE) and other plastic containers to inform possible regulatory action under the Toxic Substances Control Act (TSCA). The deadline for submitting comments is November 29, 2024. PFOA and twelve other PFAS compounds are created during the fluorination of HDPE plastic containers by Inhance Technologies, LLC, the only U.S. company manufacturing containers using this fluorination technique (see here). Studies by EPA, independent researchers, and the company itself demonstrate that PFAS leaches from container walls into contents, exposing millions to these toxic chemicals without their knowledge. EPA notes, “Long-chain PFAS like PFOA, PFNA, and PFDA build up in our bodies and the environment over time. Even small amounts can significantly contribute to people’s long-term exposure and health risk for cancers, impacts to the liver and heart, and immune and developmental damage to infants and children.” The adverse effects of PFAS exposure are linked to serious health issues, […]

(Beyond Pesticides, September 18, 2024) A literature review in Trends in Analytical Chemistry analyzes scientific articles from the last ten years from around the globe that identify more than 300 pesticides in bee pollen. Bee pollen, often used as an edible dietary supplement, is not regulated for pesticide residues, which sparks concern for human exposure due to contamination with pesticides, heavy metals, metalloids, and mycotoxins. “Bee pollen is a food supplement that is receiving increasing attention for its nutraceutical and therapeutic properties. However, several uncertainties on the safety of this beekeeping product still exist. The present work addressed this issue through the critical evaluation of 61 studies, published over the 2014–2024 period,” the Spanish authors state. Bee pollen is produced by honey bees. After they forage on flowers and gather pollen on their hind legs (in pollen baskets or corbiculae) to transport back to the hive, it is moistened with nectar and salivary secretions to create bee pollen in the form of pellets. While the composition of bee pollen can vary between geographical locations with different flowers, the studies reviewed all utilize mass spectrometry to pinpoint pesticides, as well as mycotoxins (created by naturally occurring mold spores), that threaten human […]

(Beyond Pesticides, September 16, 2024) After the release of a hard-hitting study last week published in Science that pinpoints the cycle of increasing pesticide use with ecosystem and bat decline, resulting in higher infant mortality, Beyond Pesticides is calling for state and local action to transition public land to organic practices. Without a healthy ecosystem, the study documents increased pesticide use with dramatic adverse health effects. To take corrective action, Beyond Pesticides’ action asks governors and mayors to do the following: Eliminate the use of pesticides that imperil bats by adopting biodiversity conservation goals including— (1) ecological mosquito management with measures that recognize the benefit of preventive strategies, establish source reduction programs to manage breeding sites on public lands, educate on the management of private lands, employ programs for larval management with biological controls, and eliminate the use of toxic pesticides; (2) prohibition of systemic insecticides and treated seeds, including neonicotinoids; and (3) land management on public lands—including hospitals, higher education institutions, schools, and parks—using regenerative organic principles and organic certified practices and products, to transition to a viable organic system that prioritizes long-term health of the public, ecology, and economy. The new research connects declines in bat populations with increased […]

(Beyond Pesticides, September 13, 2024) While chemical companies persist in pushing simplistic solutions to complex problems, there is a large amount of evidence that organic farming presents effective solutions to many of those problems. Now there is new evidence that organic agriculture prevents the untold harms of pesticide-driven monoculture. In a new study, German researchers compared 16 agricultural landscapes in Lower Saxony and northern Hesse that had different combinations of semi-natural habitat, organic practices, and annual and perennial flower strips. Overall, the researchers find that organic farming provides the highest benefit to the bees, along with the presence of diverse flowering plants in and near monoculture fields. The study compares the effects of three honey bee conservation methods on the prevalence of the parasitic mite Varroa destructor and the 11 parasites Varroa transfers to bees, and the impact of these destructive organisms on bee colony growth. The findings were reported in the June issue of the Journal of Applied Ecology. Organic practices lead directly to lower parasite load and higher colony growth—essentially, the more organic crops, the more bees, and the more parasites, the fewer bees. Pesticides plus monoculture doubles the damage: Pesticides increase mortality, damage bees’ immune systems, and […]

(Beyond Pesticides, September 11, 2024) A literature review in Environments, written by researchers from South Korea and Ghana, highlights the threat to nontarget species and the biodiversity of insects that occur as a result of agricultural pesticide use. “Insects have experienced a greater species abundance decline than birds, plants, and other organisms, which could pose a significant challenge to global ecosystem management. Although other factors such as urbanisation, deforestation, monoculture, and industrialisation may have contributed to the decline in insect species, the extensive application of agro-chemicals appears to cause the most serious threat,” the authors state. The so-called “insect apocalypse” has been reported with one-quarter of the global insect population lost since 1990.  The authors, seeking to summarize the decline in insect species richness and abundance, link reliance on petrochemical pesticides and synthetic fertilizers to cascading negative impacts. Insects provide many important services, such as maintaining healthy soil, recycling nutrients, pollinating flowers and crops, and controlling pests. These nontarget and beneficial species are at risk through pesticide exposure, both directly and indirectly, which then affects these essential functions.   “Extensive and indiscriminate pesticide application on a commercial scale affects insect species abundance and non-target organisms by interfering with their growth, […]

(Beyond Pesticides, September 10, 2024) Results from a natural experiment, published in Science, shows ecosystem disruption of bat populations with cascading impacts on human health. Eyal Frank, PhD, an assistant professor of the Harris School of Public Policy at the University of Chicago, links increased insecticide use in croplands in the absence of bat species to a rise in infant mortality. As Dr. Frank says in an article in Science Daily, “[B]ats do add value to society in their role as natural pesticides, and this study shows that their decline can be harmful to humans.”  Many farmers rely on bats as alternatives to pesticides to protect their crops from insects, but White-Nose Syndrome (WNS) has greatly impacted bat populations since 2006. With the collapse of many bat populations in counties in North America, these farmers turn to toxic chemicals to replace the ecosystem services bats usually provide. These chemicals, however, lead to ripples through the ecosystem and endanger human health.  WNS is an invasive fungus (Pseudogymnoascus destructans) found in caves that affects bats during hibernation. As highlighted in an article in the New York Times, three species of bats in North America have been decimated by this syndrome, and bats […]

Image: Art Page submission from Sara Grantham, “Sunflower Pollinators”  (Beyond Pesticides, August 23, 2024) A study in Science of The Total Environment calculates and compares pesticide risk in 594 wild bee species associated with crops in North America. Current pesticide risk assessments that analyze effects on bees primarily focus on a limited subset of species and do not provide comprehensive protection of all wild bees. “Species commonly proposed as models for pesticide risk assessments may not accurately represent risk for those bee species facing the highest potential risk in agricultural contexts,” the authors postulate. The researchers continue, “This study presents a novel approach to characterize and compare the relative potential pesticide risk among wild bee species of their association with crops in North America using suites of intrinsic bee traits to quantify species’ vulnerability and extrinsic factors based on the toxic load of crops for bees and the strength of each species’ association with those crops.” In considering multiple factors that vary by species and determining potential harm to each from pesticide exposure, this study highlights the inadequacies of the current risk assessment process used by the U.S. Environmental Protection Agency (EPA).    The system for risk assessment for pesticides that […]

(Beyond Pesticides, August 13, 2024) With novel methods to provide a big-picture view of the overlap between high pesticide use and cancer incidence across the U.S, a new study has again linked pesticide exposure to a range of cancers. The study by Jacob Gerkin, D.O. and colleagues, “Comprehensive assessment of pesticide use patterns and increased cancer risk,” published in Frontiers in Cancer Control and Society, examines the association between high-pesticide use and cancer diagnoses along with smoking incidence data and the Social Vulnerability Index, a measure used by the Centers for Disease Control and Prevention (CDC) that includes variables such as poverty, poor housing, and exposures to natural disasters and chemical spills. The researchers consider 69 pesticides used in agriculture that are monitored by the U.S. Department of Agriculture. They use U.S. Geological Survey data to map areas of similar crops and pesticide use patterns and incorporate public health data from the CDC to develop their final picture. In terms of threats to health, cancer remains top of mind for most people. Globally, about ten million people die of cancer each year. And while treatments for cancer and survival times have burgeoned over the years, many cancers—particularly colorectal and breast […]

(Beyond Pesticides, August 12, 2024)  When the U.S. Environmental Protection Agency (EPA) issued an emergency ban of the weed killer Dacthal (DCPA) last week, it said that there are no “practicable mitigation measures” to protect against identified hazards—a clear and honest assessment of the limits of pesticide product label changes and use restrictions. Now, the question is whether the same thinking can be applied across the EPA’s pesticide program, addressing the urgent need to protect biodiversity. In the Dacthal proclamation, EPA said it consulted with the U.S. Department of Agriculture (USDA) on “alternatives to this pesticide,” and presumably determined that there were “alternative chemicals” that could be used in chemical-intensive agriculture—while not considering “alternatives to chemicals.” This is the framework that is understood to be EPA’s process that keeps pest management on a pesticide treadmill except in extremely rare cases (this being the second in nearly 40 years). It is also the framework that has led to catastrophic events or existential crises on biodiversity collapse, health threats, and the climate emergency. On biodiversity, the mix of diverse and intricate relationships of organisms in nature that are essential to the sustaining of life, EPA’s pesticide program, the Office of Pesticide Programs, has […]

(Beyond Pesticides, August 5, 2024) As the longstanding problem of involuntary pesticide exposure through chemical drift continues unabated, EPA announced “new, earlier protections” that are being criticized by Beyond Pesticides as inadequate. The organization is calling on the public to let EPA and Congress know that it must comprehensively eliminate nontarget chemical trespass. Beyond Pesticides notes that the recent EPA announcement does not stop the movement of pesticides off the target sites restricted by pesticide product labels and therefore does not protect the public and environment in agricultural, rural, suburban, and urban areas from resulting health and ecological threats. EPA’s July 15, 2024, press release, “EPA Announces New, Earlier Protections for People from Pesticide Spray Drift” states, “The Agency is not making any changes to its chemical-specific methodology outlined in the 2014 document but has decided to extend the chemical-specific spray drift methodology to certain registration actions.” Although EPA should evaluate every pesticide use for its drift potential, extension of an inadequate process does not constitute “protection.” >> Tell EPA and Congress that EPA must protect against all forms of pesticide drift. Pesticide drift—more properly designated “chemical trespass”—is a threat to people living in agricultural, rural, suburban, and urban areas, […]

(Beyond Pesticides, July 29, 2024) Beyond Pesticides is asking the public to support a petition to the U.S. Environmental Protection Agency (EPA), filed by environmental and farm groups, to require the agency’s pesticide registration program to ban PFAS (so-called “forever chemicals”) as pesticide ingredients and all their uses that result in contamination of pesticide products. The petition, submitted by the Center for Food Safety (CFS) on behalf of 12 other petitioners, asks EPA to: “(1) ban PFAS as pesticide ingredients; (2) adopt a broad definition of PFAS chemicals that reflect the current scientific understanding of the class of chemicals; (3) prohibit the use of PFAS-containing containers for pesticide storage; (4) mandate reporting of PFAS contamination from pesticide registrants; and (5) prevent future contamination by requiring pesticide manufacturers to submit data specific to PFAS before future registrations can be approved.” PFAS—per- and polyfluorinated substances—is a group of nearly 10,000 highly persistent, human-made toxic chemicals. A commentary released last week in Environmental Health Perspectives, Forever Pesticides: A Growing Source of PFAS Contamination in the Environment, “explore[s] different ways that PFAS can be introduced into pesticide products, the extent of PFAS contamination of pesticide products, and the implications this could have for human […]
