(Beyond Pesticides, November 22, 2024) With numerous campaigns at the state and federal level to ban the weed killer paraquat and nearly 6,000 individual lawsuits alleging exposure to it causes Parkinson’s disease (PD), U.S. Senator Cory Booker (D-NJ) and six Senators on October 31 called on the U.S. Environmental Protection (EPA) to ban the chemical. Citing that “[f]armworkers and rural residents are disproportionately exposed to paraquat,” the Senators’ letter to EPA stating that, “Paraquat has been linked to Parkinson’s disease, thyroid cancer, and other health harms such as kidney, liver, and respiratory damage, and reproductive harm, including neurodevelopmental impact on developing fetuses [and] [i]n rural areas, exposure to paraquat and other pesticides during pregnancy can increase the risk of leukemia.” Most of the 6,000 cases against paraquat’s manufacturer, Syngenta, have been consolidated into Multi-District Litigation (MDL) in the U.S. District Court for the Southern District of Illinois. In April the MDL judge ousted the plaintiffs’ expert witness regarding causality, which resulted in the first five cases ready for trial being tossed out. The defendant sells paraquat globally and is doing everything it can, according to investigative news reports, to discredit any link between paraquat and Parkinson’s, including the use of […]

(Beyond Pesticides, November 21, 2024) Be it Patagonia Provisions or Brooklyn Brewery, there is a buzz around organic beer that is increasingly evident given interest by brewing and food companies. The expansion of the organic beer market in the United States would not have been possible without the leadership of advocates, farmers, breweries, and the National Organic Standards Board (NOSB), which led to the strengthening of organic standards for beer back in 2010. The growth of this sector and transition to truly organic beer speaks to the spirit of “continuous improvement,” the original design of the Organic Foods Production Act (OFPA), and the importance of mobilizing the public to engage in the public input process that continues to keep organic law strong in opposition to those seeking an easier path to the organic label. Continuous Improvement and Organic Hops In the original drafting of OFPA, advocates came together to determine how to encourage the development of certified organic sectors despite the lack of available, verifiable organic inputs for many products—beer included. With this spirit in mind, the improvement of standards for beer encapsulates the significance of OFPA in the context of its flexibility, incentives, and the statutory intent to encourage […]

(Beyond Pesticides, November 20 2024) The perpetual use of pesticide coated seeds and tillage changed the composition of various beetle, spider, and other epigeal arthropod communities on New Hampshire farmland, according to a recent study published in Agriculture, Ecosystems, and Environment. Researchers fell short of finding conclusive results about the multi-variable impacts of both practices on biodiversity but raise notable issues on the impact of treated seeds. This research builds on the existing peer-reviewed scientific literature that highlights the threats of toxic pesticides and pesticide-coated seeds. Environmental and public health advocates are in agreement with organic and agroecological farmers who reject chemical-intensive land management practices. “At the root of the cascading crises of public health collapse, biodiversity loss, and the climate crisis is a reliance on petrochemical-based toxic products, rather than public policy and investments that strengthen consumer and institutional trust of nature-based, organic systems,” says Max Sano, organic program associate at Beyond Pesticides. “This is consistent with various interactions I have had with advocates across New England who are demanding action to stymie the impending biodiversity collapse enabled by government inaction.” Background and Methodology This study was coauthored and led by environmental researchers at the Department of Natural Resources […]

(Beyond Pesticides, November 19, 2024) Researchers at Stanford University recently published a study in Cancer, an international interdisciplinary journal of the American Cancer Society (ACS), that reveals a correlation for numerous pesticides with increased prostate cancer occurrence and associated death. The study finds that exposure to 22 pesticides is positively associated with prostate cancer. The 22 pesticides include 2,4‐D, acephate, azoxystrobin, bifenthrin, carbaryl, chloropicrin, cloransulam‐methyl, cyhalothrin‐lambda, diflufenzopyr, diuron, glyphosate, hexazinone, linuron, methyl parathion, pendimethalin, propiconazole, sulfosate, thiamethoxam, thifensulfuron, tribenuron methyl, trifloxystrobin, and trifluralin. (See more on 2,4-D and cancer prevalence here and here.) As prostate cancer is a leading national health concern, the authors investigate agricultural pesticide exposure and compared it to prostate cancer incidence and mortality across counties in the contiguous U.S. “The geographic variation in prostate cancer incidence and mortality suggests that regional environmental factors, such as pesticide exposure, may contribute to the development of prostate cancer,” the researchers postulate. In comparing county‐level associations of 295 pesticides and prostate cancer reports, the authors were able to conduct an environment‐wide association study (EWAS) to determine any statistically significant links. “We acquired annual estimated total usage data (kg per county) for all pesticides reported and applied to agricultural crops grown […]

(Beyond Pesticides, November 18, 2024) With the reported appointment of former U.S. Representative Lee Zeldin (R-NY) to the position of Administrator of the U.S. Environmental Protection Agency (EPA), Senate confirmation hearings will be an important process that is intended to shine a light on individual nominations, the policies of an administration, and the science (or lack thereof) behind them. There have been reports in the media that the Trump administration may attempt to circumvent the “advice and consent” rule of the U.S. Senate by making recess appointments. Alexander Hamilton wrote in the Federalist Papers: No. 76 that Senate confirmation hearings act as a safeguard against the appointment of “unfit” officials. Numerous interviews and critiques are painting a picture of what the future holds for environmental protection and all that means for addressing the serious catastrophic threats of ongoing and escalating health, biodiversity, and climate crises. “Mr. Trump, who has called climate change a “hoax,” has targeted “every one” of Mr. Biden’s policies designed to transition the United States away from fossil fuels,” according to The New York Times reporting on June 26, 2024. The Guardian reported on October 1 after Hurricane Helene, “As the hurricane continued to ravage the region over […]

(Beyond Pesticides, November 15, 2024) There are many pie-in-the-sky ideas to address the climate crisis while allowing business as usual in the extractive and industrial systems that are causing the crisis. Prominent among them are geoengineering to block sunlight and building industrial plants to prevent carbon dioxide (CO2) from reaching the atmosphere, known as carbon capture and sequestration (CCS). Like geoengineering, CCS is a “solution for the future that always will be.” It has garnered decades of hype, research, and government funding of prototype projects without doing much of anything to remove carbon and keep it out of the atmosphere. The Biden administration’s Inflation Reduction Act (IRA) contains numerous revenue streams aimed at coping with the climate crisis, including CCS. But it is a mixed bag of good and bad ideas. Beyond Pesticides analyzed the IRA in 2022, lauding the act’s “provision of unprecedented sums to address the existential threats we face related to climate, biodiversity, and health.” These include about $21 billion for “climate smart” agriculture and programs to reduce petrochemically dependent farming. But the analysis also details the many provisions for infeasible and counterproductive projects. Rather than complex and expensive technological projects, the best practitioners of CCS are […]

(Beyond Pesticides, November 13, 2024) A study in Chemosphere, conducted by researchers from the Institute of Biochemistry and Molecular Biology in Germany, reveals the varied lethal and sublethal effects of different glyphosate mixtures through tests on the South African clawed frog, Xenopus laevis (X. laevis). After exposing embryos to four glyphosate formulations, mortality, morphological defects, altered heartbeat rate, and impaired heart-specific gene expression are observed. Glyphosate, an herbicide and popular weed killer in many Roundup® products, is one of the most commonly detected pesticides in waterbodies worldwide, threatening aquatic organisms and overall biodiversity. This study investigates the effects of Glyphosat TF, Durano TF, Helosate 450 TF, and Kyleo, four formulations containing glyphosate, as compared to the effects of pure glyphosate on embryonic development in amphibians. The formulations consist of varying concentrations of the active ingredient glyphosate, as well as other active and inert ingredients. The authors share that, “Glyphosat TF contains 34% glyphosate and 10–20% d-glucopyranose, while Durano contains 39–44% glyphosate and 1–5% N–N-dimethyl-C12-C14-(even numbered)-alkyl-1-amines. In Helosate most of the ingredients are listed – 50–70% glyphosate, 1–10% isopropylamine, 1–3% lauryl dimethyl betaine, 0.25–1% dodecyl dimethylamine. Kyleo only lists the active ingredients glyphosate (27.9%) and 2,4-D (32%).” 2-cell stage embryos (early […]

(Beyond Pesticides, November 7, 2024) Organic banana production is significantly more conducive to microbial decomposition than its chemical-intensive counterparts in the Caribbean nation of Martinique, according to a recent study published in Applied Soil Ecology. “Macrofaunal decomposition was increased more (55%) than microbial decomposition (20%), indicating that organic farming removes a constraint of conventional farming especially affecting macrofauna.” Biological activity in the soil is foundational to organic land management and critical to the cycling of nutrients that feed plant life while contributing to resiliency and soil water retention. Bananas are one of the most highly consumed fresh fruits in the U.S. marketplace. A consumer survey conducted by the International Fresh Produce Association in 2023 identified 84% of households purchasing bananas that year. The U.S. Department of Agriculture (USDA) Economic Research Service identifies bananas as the third most consumed fruit product in the United States, with the average person eating 13.2 pounds that year. Since bananas require specific bioclimatic conditions for commercial production that meets ongoing consumer demand, the proliferation of industrial-scale monoculture banana plantations in various Central and South American countries and territories has and continues to devastate local and Indigenous communities for generations. Environmental justice and public health advocates […]

(Beyond Pesticides, November 5, 2024) Published in the journal Frontiers in Toxicology, a recent study uncovers serious flaws in the pesticide registration process at the U.S. Environmental Protection Agency (EPA) with an in-depth evaluation of the agency’s failure to protect the public from the harmful effects of five neonicotinoid (neonic) insecticides—as mandated by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and amendments, including Food Quality Protection Act (FQPA) of 1996. This coincides with EPA’s ongoing review to renew their approval for the next 15 years (set to be announced in 2025). The report is based on the first comprehensive assessment of unpublished rodent-based Developmental Neurotoxicity (DNT) studies, conducted between 2000-2003 and submitted by pesticide manufacturers as part of the registration process. All five neonicotinoids evaluated—acetamiprid, clothianidin, imidacloprid, thiacloprid, and thiamethoxam—are associated with significant shrinkage of brain tissue at the highest dosage, according to EPA data reports (see acetamiprid, clothianidin, imidacloprid, thiacloprid, and thiamethoxam). However, with little or no data regarding the chemicals’ impacts at low and mid-level dosages, EPA has either failed to find a “No Observed Adverse Effect Level” (NOAEL) or, seemingly at random, set the NOAEL at the mid-level dosage. The evaluation suggests that perinatal exposure to […]

(Beyond Pesticides, November 1, 2024) In a study published earlier this year in Soil Science Society of America Journal, researchers at Kansas State University document direct evidence that organic amendments (e.g., manure and compost) in a no-till agricultural system “facilitat[e] microbial diversity” that cycles plant-available nutrients. The study was published just as farmers are looking for less expensive practices that support the economic vitality of their farms amid surging prices for petrochemical pesticides and fertilizers and as agricultural support programs are threatened by unresolved issues in Farm Bill talks on Capitol Hill. [See the recent Action of the Week calling on Congress to take action.] Simultaneously, awareness is growing among environmental and public health advocates about the importance of soil health to ecosystem stability in combatting climate change-induced natural disasters and stopping plummeting biodiversity. Demands for new systems rooted in organic principles and land management practices continue to become more widely recognized by farmers, environmentalists, and the broad public. The study adds to earlier findings and contributes to the body of scientific literature on soil health and its importance to ecosystem and human health. Methodology and Results The study was led by researchers at Kansas State University specializing in agronomy […]

(Beyond Pesticides, October 31, 2024) Approximately four in ten private wells in the state of Wisconsin contain toxic pesticides and pesticide metabolites, according to findings released earlier this year from a 2023 survey, entitled Wisconsin Agricultural Chemicals in Wisconsin Groundwater, conducted by the Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP) in partnership with U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS). An analysis of the survey findings from Wisconsin Public Radio determined that “more than half of 29 pesticide compounds detected are unregulated in groundwater.” Pesticides detected in this study include toxic herbicides atrazine, dacthal, metolachlor, and alachlor, commonly used by chemical-intensive corn and soybean growers throughout the United States, but they are particularly concentrated for use in Corn Belt states such as Wisconsin. Various neonicotinoid insecticides were also detected. Pesticide leaching into both surface water and groundwater continues to impose adverse health and environmental impacts on communities across the nation, leading to advocates pushing for organic land management principles and practices to avoid the continuous use of toxic pesticides. Methods and Findings “Of the 29 compounds detected, [Carla] Romano [groundwater specialist at DATCP] said 13 have established groundwater standards,” based on an interview conducted by […]

(Beyond Pesticides, October 28, 2024) STARTS WEDNESDAY—NATIONAL FORUM: IMPERATIVES FOR A SUSTAINABLE FUTURE. As scientific articles and regulatory reviews by the U.S. Environmental Protection Agency (EPA) focus on individual pesticides or families of pesticides and specific health outcomes associated with exposure, legislation introduced by U.S. Senator Cory Booker (D-NJ), S. 5084, Safe School Meals Act (SSMA), proposes a holistic response to the protection of children by banning pesticides in school lunches. While focused on the elimination of certain individual pesticides and other chemicals of known concern, the bill unilaterally allows children to be served food from certified organic farms. The overwhelmingly large body of scientific findings on the adverse effects of pesticides in the food that children eat in schools and generally. For example, last week Beyond Pesticides commented on EPA’s Draft Human Health and/or Ecological Risk Assessments for Several Pesticides, citing scientific findings that, “Neonicotinoids . . .have been found to affect mammalian nicotinic acetylcholine receptors (nAChRs) [which] are of critical importance to human brain function, especially during development and for memory, cognition, and behavior.” (See more here.) This month, Jennifer Sass, PhD, et al., in Frontiers in Toxicology, published a review of  unpublished rodent developmental neurotoxicity (DNT) studies […]

(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 23, 2024) The stark contrast of two political parties emerged around this summer’s reporting of the Project 2025 blueprint—created by extreme right-wing conservatives—that proposes the gutting of environmental and public health policy and implementation. Many political observers say “Project 2025 Presidential Transition Project,” formally titled “Mandate for Leadership: The Conservative Promise,” will be embraced by a second Trump Administration, despite denials that are challenged by insiders as outright lies. While the public became aware of Project 2025 plans to gut the U.S. Environmental Protection Agency (EPA) and many other agencies, the Biden Administration was announcing the emergency ban (see also August 6 announcement), finalized yesterday, of the weed killer Dacthal, exercising an EPA authority that has not been used in 45 years since the banning of 2,4,5-T (50% of the mixture of Agent Orange). With this decision, EPA set an important precedent for proclaiming (i) an unacceptable harm, (ii) its inability to mitigate the pesticide’s hazards with typical risk mitigation measures, and (iii) the availability of alternatives that made the chemical unnecessary. In dramatic contrast, the Trump supporters behind Project 2025 are intent on politicizing science to undermine governmental structures and laws established to protect public health […]

(Beyond Pesticides, October 15, 2024) In Environmental Epidemiology, researchers from Columbia University and the University of Southern California, along with representatives from the nonprofit Comite Civico del Valle in Brawley, California, report the heightened risk of wheezing for five- to twelve-year-olds in the rural communities of California’s Imperial Valley. Through a school-based survey, the authors find associations between living near pesticide applications and more wheeze symptoms among the children. According to the authors, residents of the Imperial Valley, which is located near the border between the United States (U.S.) and Mexico, “are primarily Latino, 1 in 3 children live in poverty, and there is a 20% unemployment rate. The county faces poor air quality and excess particulate matter levels. Further, one in five children is diagnosed with asthma and the rate of asthma-related pediatric emergency room visits and hospitalizations is two times the CA state average.” This highlights the disproportionate risk for residents in this area regarding environmental exposure to harmful chemicals. Children are already more susceptible to health complications following pesticide exposure, as they take in greater amounts of toxic chemicals relative to their body weight and have still-developing organ systems. Young children in environments with higher levels of […]

(Beyond Pesticides, October 10, 2024) On September 16, 2024, the U.S. Environmental Protection Agency (EPA) announced an order allowing Kaizen Technologies LLC to sell off its chlorpyrifos-based insecticide product—Bifenchlor, a known neurotoxicant. This reverses an existing stocks agreement that Kaizen voluntarily negotiated with EPA in August 2022 when the company withdrew Bifenchlor from use. The agency attributes this new order to a November 2023 Eighth Circuit Court of Appeals decision, which vacated EPA’s prior 2021 chlorpyrifos ban on food crops (see here). EPA’s practice of permitting the sale and use of existing stocks of canceled pesticides has been a longstanding concern for public health and environmental advocates, as it enables the continued use of petrochemical pesticides that the agency has found to be dangerous. Chlorpyrifos, an organophosphate with adverse health effects on children (see here and here), is now the latest example.  In reporting on the almost unprecedented decision on August 7, 2024, to use its emergency authority to ban Dacthal/DCPA, Beyond Pesticides argues that the “Dacthal Standard” is a positive precedent, a step forward in modern regulatory history; however, EPA’s continued approval of chlorpyrifos’s existing stock, complicated by the 2023 court decision, may suggest otherwise.   As demonstrated historically with […]

(Beyond Pesticides, October 9, 2024) An agrichemical industry-funded study published in International Journal of Agricultural Sustainability dissects the development of national organic standards and opportunities that can be applied in expanding the use of “regenerative” agriculture. Not surprisingly, the study authors offer support for integrated pest management (IPM) and reassurance of a rigorous pesticide registration review process before the chemicals are marketed. The study included a survey of five farmers, who farm a total of 100,000 acres, but do not have extensive experience farming organically. For those practicing regenerative organic practices and organic advocates, the bottom line is that the study concludes that a list of criteria that would be needed for regenerative agriculture criteria (e.g., list of allowed substances) already exists within the standards and requirements of the 1990 Organic Foods Production Act (OFPA) and the National Organic Program. Environmental and public health advocates are concerned about this piece representing an industry position being cloaked in an academic journal serving as an obstacle to the widespread adoption and improvement of organic principles and practices. The study was written by four authors with varying levels of connections to CropLife America (the major agrichemical industry trade group), including academic researchers with […]

(Beyond Pesticides, October 7, 2024) American Academy of Pediatrics (AAP) released a newly revised technical report describing how antibiotic use in animal agriculture contributes to the development of antibiotic resistance in medical use and can adversely affect child health— in the context of this fast-emerging threat to U.S. and global health. This AAP finding comes just as the United Nations (UN) held its second High-Level Meeting on Antimicrobial Resistance (AMR) on September 26 (the first was held in 2016) at which global leaders committed “to a clear set of targets and actions, including reducing the estimated 4.95 million human deaths associated with bacterial antimicrobial resistance (AMR) annually by 10% by 2030.” The release from the UN, “World leaders commit to decisive action on antimicrobial resistance,” states, ”The Food and Agriculture Organization of the United Nations (FAO), the United Nations Environment Programme (UNEP), the World Health Organization (WHO) and the World Organisation for Animal Health (WOAH), known as the Quadripartite, welcome the declaration. The Quadripartite applauds countries for recognising the need for global, regional and national efforts to address AMR through a One Health approach, which recognizes that the health of people, animals, plants and the wider environment, including ecosystems, are closely […]

(Beyond Pesticides, October 3, 2024) The American Academy of Pediatrics published a technical report in September on antimicrobial resistance, which it calls a global public health threat, identifying the health implications of antibiotic use in animal agriculture. The lead authors, both medical doctors from the Department of Pediatrics at Vanderbilt University Medical Center, note the rise in antimicrobial-resistant infections that result in increased morbidity, mortality, and health care costs for not only adults, but infants and children as well. “[A]ll use of antimicrobial agents exerts selective pressure that increases the risk of development of resistance,” the authors state, highlighting the importance of limiting antimicrobial uses. “Antimicrobial resistance is an organism’s ability to survive exposure to an antimicrobial agent that was previously an effective treatment. Resistance traits can be acquired either through new mutations or through transfer of genetic material between organisms,” the authors report. Antimicrobial-resistant pathogens, such as bacteria and viruses, can be transmitted “through the food supply, direct contact with animals, environmental pathways, and contact with infected or colonized humans,” they continue. Use of antimicrobial agents, especially over extended periods of time or with repeated exposure, can cause resistance to not only that agent, but to multiple agents. As […]

(Beyond Pesticides, September 30, 2024) Public Comment Period on Issues of Organic Integrity Closes Today. Farming is a notoriously risky enterprise, and organic farming presents further challenges along with its multiple benefits. Generally, organic has made great strides over the last several years and is strongly supported by American consumers, findings in the latest U.S. Department of Agriculture (USDA) Census. Even late this year, there is the prospect of several more important changes that will improve the organic certification process and some issues that will take more policy changes to resolve in the future. As a part of this process to ensure the integrity of the USDA organic label and the permitted production practices, Beyond Pesticides urges that the public submit comments TODAY (the last day for the comment period) on issues currently before the National Organic Standards Board (NOSB). See two sets of comments on key issues that can be submitted with one click each. Click here on issues related to use of plastic, nonorganic ingredients in processed food, and seeds and plant starts. Click here on inert ingredients, contaminants in compost, and drugs in livestock production. U.S. agriculture overall has remained fairly robust between the USDA Census in […]

(Beyond Pesticides, September 25, 2024) In a semiannual report released in August 2024, EPA’s Office of Inspector General (OIG) identifies a number of “unresolved” issues that strike the core of the agency’s failure to carry out its responsibilities to protect health and the environment. One of the issues identified is EPA’s failure to conduct an adequate and independent assessment of the cancer effects of the fumigant, 1,3-Dichloropropene (1,3-D or Telone). OIG’s original report, The EPA Needs to Improve the Transparency of Its Cancer-Assessment Process for Pesticides, was issued in 2022 and concluded that EPA’s Office of Pesticide Programs (OPP) engages in secret meetings with industry, elevates unqualified individuals to decision-making roles, uses an untested scientific approach, fails to conduct a simple literature review, and neglects public transparency. Other pesticide issues that OIG identified in its report include: The EPA Needs to Determine Whether Seresto Pet Collars Pose an Unreasonable Risk to Pet Health The EPA Has Not Verified that Its Laboratories Comply with Hazardous Waste Requirements EPA Needs an Agencywide Strategic Action Plan to Address Harmful Algal Blooms EPA’s Endocrine Disruptor Screening Program Has Made Limited Progress in Assessing Pesticides EPA Needs to Evaluate the Impact of the Revised Agricultural Worker […]

(Beyond Pesticides, September 24, 2024) Recent commentary in Frontiers in Toxicology by two researchers, Maricel Maffini, PhD and Laura Vandenberg, PhD, highlights the pitfalls in the current regulatory systems in the United States (U.S.) for chemicals that threaten human health. Despite many advancements in science over the past few decades, and the wealth of studies that tie chemical exposure to negative health effects, risk assessments, and subsequent risk management, remain “static” and “outdated,” according to the authors. “There is increasing concern amongst public health professionals, environmental health scientists, and medical organizations about exposures to synthetic chemicals,” the researchers say. “These organizations’ concerns are based on the overwhelming evidence showing associations between chemical exposures and adverse health outcomes in human populations.” Such concerns have sparked a debate on current regulatory methods for chemicals that are present in highly used products, such as pesticides, plastic containers, and food.    The authors continue, “There are now thousands of studies showing associations between these chemicals and adverse health effects in humans including neurological disorders and learning disabilities, metabolic outcomes, infertility, thyroid dysfunction, and cancers.” Additional health effects can be seen in the Pesticide-Induced Diseases Database. Of the many harmful chemicals, per- and polyfluoroalkyl substances […]

(Beyond Pesticides, September 19, 2024) An article published in the journal Science of the Total Environment finds that the European Union’s (EU) risk assessment process, required for registration, fails to accurately or reliably predict pesticide exposure rates, sometimes by several orders of magnitude. Pesticide registration in the EU leverages the Agricultural Operator Exposure Model (AOEM)—a predictive model developed in 2014 to estimate expected non-dietary pesticide exposure levels for operators [pest control operators in the U.S.] based on a very limited set of data generated by the pesticide industry. Models that predict real-world exposure and underestimate field data raise critical questions about the efficacy of risk assessment reviews that determine product labels and allowed level of harm. By comparing the dermal exposure measured during a field study conducted in a nonagricultural area with the corresponding values estimated by AOEM, researchers in France add to the body of scientific literature indicating that the fossil fuel and petrochemical pesticide industry data cannot be relied upon as a benchmark to ensure public health and safety. The study describes the difficulty and complexity of calculating the ability of protective equipment to provide protection. According to the authors, “[AOEM] underestimated hand exposure by 42 times and […]
