(Beyond Pesticides, August 8, 2025) In a study published in Environmental Pollution, researchers have detected eighty pesticides (35 insecticides, 29 fungicides, and 11 herbicides, and metabolites) in the ambient air of a rural region of Spain (Valencia) between 2007 and 2024. Despite these dramatic findings, the authors conclude that there is “no [observable] cancer risk,†“no inhalation risk for adults,†and only one pesticide concentration (the insecticide chlorpyrifos) showing “a potential risk to toddlers.†However, the authors did not conduct an aggregate risk assessment that would typically consider all routes of exposure to the individual pesticides detected, including through water, food, and landscapes. Not considered by the authors are the potential effects of pesticide mixtures and full pesticide product formulations (with all potentially toxic ingredients), also a deficiency in the U.S. Environmental Protection Agency (EPA) registration of pesticides under federal law. Of concern, as well, are other contaminants in pesticide products, including but not limited to per- and polyfluoroalkyl substances (PFAS), heavy metals, plastics (including microplastics), which contribute to chronic diseases and health risks, and adverse effects to ecosystem stability exacerbated by the climate crisis.

(Beyond Pesticides, August 7, 2025) The novel study published in Arthritis & Rheumatology is the largest investigation of rheumatoid arthritis (RA) in women to date, finding evidence of heightened risks when exposed to insecticides through data collected from over 400 eligible women in the Agricultural Health Study (AHS). AHS participants include a cohort of thousands of licensed pesticide applicators and their spouses from Iowa and North Carolina, with this particular study as the first to consider the link between pesticide exposure and RA as it affects women’s health.  “Growing evidence suggests farming and agricultural pesticide use may be associated with rheumatoid arthritis (RA), but few studies have examined specific pesticides and RA among farm women, who may personally use pesticides or be indirectly exposed,†the study authors explain. The findings reveal that organochlorine insecticides that continue to persist in the environment, as well as organophosphate and synthetic pyrethroid pesticides used in public health or residential settings, correlate with RA diagnoses in women. As shared in previous Daily News, for the most part organochlorine pesticides, including dichlorodiphenyltrichloroethane (DDT), are no longer used worldwide, but the legacy of their poisoning and contamination persists.

(Beyond Pesticides, August 6, 2025) A study published in Science of The Total Environment finds that “chronic pesticide exposure alters metabolism and impairs fish growth and health.†With increasing concern about the long-term consequences of pesticide persistence in ecosystems, the scientific literature continues to expand the body of research findings on adverse effects, including impacts on marine or aquatic ecosystems and organisms. Given the known and growing risks, there is an ongoing movement to move beyond petrochemical-based chemicals for agriculture and land management by adopting policies and programs that advance organic criteria and principles, as outlined in national organic law and practiced by tens of thousands of certified farmers and land managers across the country, and even more at the international level. Background and Methodology “The objective of this study was to assess the physiological responses of juvenile P. lineatus exposed to environmentally relevant pesticide mixtures by integrating multiple biological endpoints across sub-individual and organismal levels,†the authors write. The study was conducted at two sites in the Tibagi River watershed located in Paraná, a southern region in Brazil. There was a reference site (RFS) and an agricultural site (AGS), the former having minimal . . .

(Beyond Pesticides, August 5, 2025) A biomonitoring study in Environmental Geochemistry and Health, focused on small-scale farms in Pahang, Malaysia, analyzes levels of essential and toxic elements in hair and nail samples from chemical-intensive and organic farmers. While the results reveal elements that correlate with specific farming practices, common elements to both chemical-intensive and organic farming highlight the role of pesticide drift in off-target contamination, diminishing some of the benefits of organic agriculture. The persistent and pervasive nature of many pesticide products results in exposure patterns, in addition to direct occupational exposure on chemical-intensive conventional farms, that trespass onto organically managed land and threaten health and the environment—raising policy and practice issues needed to safeguard the public. Cameron Highlands in Malaysia is a region known for intensive pesticide use as well as for its vegetable and flower farming, where both conventional and organic agriculture exist in close proximity. “Despite different agricultural approaches, both groups remain at risk of environmental exposure due to long-term pesticide application in the region,†the authors write. They continue, “While organic farming practices may reduce direct exposure to synthetic agrochemicals, the risk of cross-contamination from surrounding conventional farms remains a concern . . .

(Beyond Pesticides, August 4, 2025) Comments on EPA proposal to bring back controversial use of herbicide dicamba due by Friday, August 22, 2025, at 11:59 PM ET. With more than 90 percent of soybeans (also corn and the most common species of cotton) planted in varieties genetically engineered to be herbicide-tolerant, the agrichemical industry and industrial agribusiness are lining up to bring back agricultural spraying of the controversial weed killer dicamba—linked to crop damage associated with the chemical’s drifting off the target farms. The courts in 2020 and 2024 vacated EPA’s registration authorizing “over-the-top†(OTT) spraying of dicamba, leading to these uses being stopped in the 2025 growing season. (See Daily News.)             Genetically engineered crops, widely adopted in 1996 with Monsanto’s glyphosate-tolerant (Roundup Ready) soybean seeds and plants, have been plagued by weed resistance to the weed killers, movement of genetic material, chemical drift, and health and environmental hazards associated with pesticide exposure. Despite the problems and escalating herbicide use in chemical-dependent no-till (no tillage) agriculture, regulators at the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Agriculture (USDA) have facilitated the astronomical growth of a genetically engineered food system.

(Beyond Pesticides, August 1, 2025) On June 30, Kyle Kunkler started work as deputy assistant administrator for pesticides in U.S. Environmental Protection Agency’s (EPA) Office of Chemical Safety and Pollution Prevention. Mr. Kunkler is an experienced agribusiness lobbyist, having come directly from the American Soybean Association, where he was director of government affairs. He joins Nancy Beck, PhD, herself a migrant from the American Chemistry Council. Not coincidentally, a mere three weeks after Mr. Kunkler’s appointment, EPA opened the floodgates to allow use of the controversial herbicide dicamba to flow unrestricted once again through the nation’s ecosystems. Dicamba has been associated with phytotoxic crop/plant damage (leaf damage, stunted growth, or death) and cancer. Three formulations of the herbicide whose registrations had been vacated via litigation will be reinstated by EPA after a public comment period that expires on August 22 at 11:59 PM EDT. Dicamba is manifestly one of the worst ideas the pesticide industry has ever devised, according to many farmers and pesticide safety advocates. Because of resistance to other herbicides, pesticide scientists developed the “[insert pesticide]-ready†concept in which a crop plant is genetically engineered to resist exposure to a herbicide, “Roundup-Ready†. . .

(Beyond Pesticides, July 31, 2025) A study published in Environmental Advances finds that hundreds of honeybee hives across central and northern Italy are contaminated with various pesticides and their metabolites, including glyphosate and fosetyl. “There was no significant difference in glyphosate presence between dead/dying and live bees, suggesting chronic exposure rather than acute toxicity. However, higher pesticide concentrations in dead/dying bees indicate potential sublethal effects contributing to colony distress,†according to the authors. This peer-reviewed study builds on the mounting evidence outlined in the literature connecting pesticide residues to nontarget harm to pollinators and other insects and animals that are critical to biodiversity. Background and Methodology “The primary objectives of this study were to develop and validate a reliable, sensitive method for analyzing polar pesticides [highly soluble in water] in honeybees and to investigate polar pesticides residue levels in honeybees across northern and central Italy,†say the researchers of this study, who conduct research at the Experimental Zooprophylactic Institute of Lombardy and Emilia Romagna “Bruno Ubertini”, Experimental Zooprophylactic Institute of Umbria and Marche “Togo Rosatiâ€, and Experimental Zooprophylactic Institute of Lazio and Tuscany “M.

(Beyond Pesticides, July 30, 2025) The definition of per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals†due to their persistence, continues to be debated in regulatory agencies, with many scientists arguing that certain types of chemicals in this vast group are not accurately captured in risk assessments. A wide body of science on the adverse health and environmental effects of PFAS exists, as these synthetic chemicals have become ubiquitous in nature, wildlife, and humans, as demonstrated by biomonitoring studies. Recent research, documented in a literature review in Environmental Science & Technology and additional articles, highlights the importance of a universal, cohesive definition of PFAS that incorporates all fluorinated compounds, including the long carbon chain PFOA (perfluorooactanoic acid) and PFOS (perfluorooctanesulfonic acid) as well as the ultrashort-chain perfluoroalkyl acids (PFAAs). In order to protect health and the environment from the ever-increasing threat of both long and short chain PFAS’ adverse effects, including cancer, endocrine-disrupting effects, and immune system damage, a comprehensive definition of the compounds causing harm is critical to adequate protection and regulatory decisions. The multitude of sources of PFAS and various exposure routes leads to widespread contamination of the environment and . . .

(Beyond Pesticides, July 29, 2025) Are neurological diseases increasing around the world? Yes and no, according to a report published by The Lancet in 2024 on the global burden of nervous system diseases between 1990 and 2021. About 3 billion—a third of the world’s people—suffer from some nervous system condition. These diseases cause 11 million deaths and 443 million disability-adjusted life years (DALYs), which are a measure of the years lost to illness, disability, or early death. Neurological disorders are now the world’s largest source of disability. The Lancet report does not include an analysis of the role of pesticides in the burden of neurological disease worldwide, although environmental health research continues to expand the evidence that pesticide exposure is a major contributor to that burden. The Lancet report indicates that DALYs from Parkinson’s disease have increased by 10 percent, and autism spectrum disorder and dementia by 2 percent each. Multiple sclerosis has declined by 11 percent, according to the report. Importantly, most of the improvement has come from medical interventions, not prevention—in other words, people are living longer with the diseases rather than avoiding them altogether. But this is not true globally: The burden of . . .

(Beyond Pesticides, July 28, 2025) As the problem of antimicrobial-resistant infections continues to escalate to pandemic proportions, Beyond Pesticides is again calling on Congress and the federal government to urgently start to eliminate the use of pesticides that contribute to antibiotic resistance. While data accumulates on antimicrobial resistance, including Daily News reporting of yet another study in June in Environmental Geochemistry and Health, the 79th United Nations General Assembly High-Level Meeting on antimicrobial resistance (September 2024) points to  nearly five million deaths in 2019 from antibiotic-resistant microbial infections and $1 trillion in annual health care costs per year by 2050 globally. According to the UN’s political declaration, “[G]lobally, antimicrobial resistance could result in US$ 1 trillion of additional health-care costs per year by 2050 and US$ 1 trillion to 3.4 trillion of gross domestic product losses per year by 2030, and that treating drug-resistant bacterial infections alone could cost up to US$ 412 billion annually, coupled with workforce participation and productivity losses of US$ 443 billion, with antimicrobial resistance predicted to cause an 11 per cent decline in livestock production in low-income countries by 2050.†These findings grow out of “[G]eneral Assembly resolution 78/269, to . . .

(Beyond Pesticides, July 25, 2025) The scientific literature shows that microplastics (MPs) and pesticides, both ubiquitous throughout the environment, have synergistic effects that threaten aquatic organisms. This means the combined toxicity of the two substances is greater than the sum of two individual exposures. The most recent study to demonstrate this, published in Ecotoxicology, focuses on the impacts of MPs and chlorpyrifos (CPF), a widely used organophosphate insecticide, on cladocerans, a group of microcrustaceans. As Beyond Pesticides has previously reported, microplastics are found in all environments and threaten not only human health but all wildlife in both aquatic and terrestrial ecosystems. The universal distribution of plastics means that they cannot be avoided. Humans and other organisms take up plastics in the form of microparticles and nanoparticles by inhalation, ingestion, and skin contact every day. Microplastics are about the width of a human hair; nanoplastics are much smaller, about twice the width of a DNA strand. Larger pieces of plastic are ground down to these tiny sizes by weathering, temperature, biological processes, and chemical conditions. (See additional Daily News coverage on the health and environmental hazards of plastics here, here, and here.) The . . .

(Beyond Pesticides, July 24, 2025) In a sixteen-year field trial based in Central Kenya, researchers have found higher crop yield stability in low-input organic systems with previously degraded soil than in high-input organic and nonorganic agricultural systems. One of the agrichemical industry-fed arguments against organic production is the false belief that, if all agricultural production went organic, then it would lead to a crisis of food security. Proponents of transitioning to organic continually push back, given the steady flow of evidence, backed by decades-long field trials, that organic can compete—and even outcompete—conventional systems after a transitional period. Background and Methodology This long-term field trial, published this year in European Journal of Agronomy, was conducted at two sites in Central Kenya—Chuka (lower soil fertility) and Kandara (higher soil fertility)—between 2007 and 2022.  Both Chuka and Kandara share bimodal rainfall (two wet seasons split up with distinct dry seasons) and consist of two growing seasons in a given calendar year. There were six crop rotation cycles for the maize, which included various legumes, vegetables, and root crops depending on the input level and farming system. The experimental design was a randomized complete block design in . . .

(Beyond Pesticides, July 23, 2025) Attention turns to the U.S. Senate on legislation that (i) shields pesticide companies from lawsuits by those harmed from pesticide product use, (ii) limits states’ authority to regulate pesticides, and (iii) prevents EPA from regulating PFAS—after passage in the House Appropriations Committee on July 22. The Senate Appropriations Committee meets tomorrow, July 24, to vote on language that has not yet been released to the public. Efforts by Democrats failed to strike sections 453, the shield provision, and 507, the PFAS (per- and polyfluoroalkyl substances) language, from the FY26 Interior-Environment Appropriations Bill. The same provisions could show up in the Senate Appropriations Bill. Beyond Pesticides is: Asking U.S. Senators to help stop Appropriations Bill provisions that strip farmers and consumers from suing for pesticide harm, ensuring that language in House Appropriations Bill, Sections 453 and 507, not be included in the Senate bill. *If Senator is on the Appropriations Committee, the letter submitted will automatically adjust the language by recognizing their Committee membership.

(Beyond Pesticides, July 23, 2025) The pesticide manufacturer Syngenta has settled several lawsuits in federal courts in Pennsylvania and Illinois in recent months and is seeking a global settlement with over 6,000 litigants in order to avoid nationwide trials linking their weed killer paraquat to Parkinson’s Disease, according to reporting by The New Lede and The Guardian, respectively. Internal Syngenta documents released by these news outlets in a report dubbed The Paraquat Papers indicate that the company was aware of scientific evidence linking paraquat to Parkinson’s and attempted to quash research efforts to disclose the evidence.  These lawsuits were filed on behalf of former farmers and agricultural workers who went on to be diagnosed with neurological disorders, including Parkinson’s Disease, after using paraquat-based herbicide products for long periods of time. This litigation comes at a time when pesticide manufacturers across the board are facing increased scrutiny and subsequent financial repercussions. Simultaneously, their allies in Congress are revamping their efforts to shield chemical manufacturers from “failure to warn†lawsuits and establish federal preemption of local state governments’ ability to regulate pesticides more stringently than the U.S. Environmental Protection Agency.

(Beyond Pesticides, July 22, 2025) A study published in May by Nature Reviews Endocrinology warns that endocrine-disrupting chemicals (EDCs)—substances that lead to disruption of the endocrine system in an organism—are driving a rapid rise in female reproductive disorders. While EDCs encompass many different forms of chemicals, such as plastic additives, cigarette smoke, and paracetamol, pesticides are among the most common EDCs. The review pays special attention to pesticide classes such as per-and polyfluoroalkyl substances (PFAS) and organochlorines to evaluate how they derail ovarian development, puberty timing, and hormonal balance across the entire female lifespan. Many pesticides are fluorinated, and therefore classified as PFAS. Background Pesticides represent one of the largest sources of EDC exposure. Many persistent organic pollutants (POPs) are resistant to degradation and are capable of bioaccumulating in the food chain, which leads to these harmful chemicals being found in human adipose tissue. The study notes that these chemicals have also been detected in human blood, breast milk, follicular fluid, and other biological samples, explaining their prevalent presence in the human body. The review emphasizes that humans are exposed to a mixture of EDCs across their lifespan, yet current U.S. regulatory strategies do . . .

(Beyond Pesticides, July 21, 2025) Beyond Pesticides is asking every member of the U.S. Representatives to voice their opposition in advance of a vote as early as Tuesday, July 22 on a provision before the House Appropriations Committee—in the Interior-Environment Appropriations Bill—that shields pesticide companies from lawsuits by those harmed from pesticide product use and limits states’ authority to regulate pesticides. This is a fight to protect farmers’ and consumers’ right to sue pesticide manufacturers for misbranding products and their failure to warn product users. The language before the Committee is in Section 453 of the bill passed last week by the subcommittee on a straight party-line vote, with Republicans supporting the bill language. Beyond Pesticides is also asking Congress members to remove section 507, which prohibits EPA action on PFAS (per- and polyfluoroalkyl substances), including fluorinated pesticides. Update from July 21, 2025, at 4 PM: ⏰ Representative Chellie Pingree (D-ME-1) moved forward with amendments to strike sections 453 and 507 of the FY26 Interior-Environment Appropriations Bill, which is a provision that provides immunity for pesticide manufacturers from farmer and consumer lawsuits seeking compensation from product harm.

(Beyond Pesticides, July 18, 2025) A study in Royal Society Open Science shows intraspecific differences (between individuals of a species) in wild bumblebees (Bombus vosnesenskii) exposed to an herbicide (glyphosate), a fungicide (tebuconazole), and an insecticide (imidacloprid), with gut microbiome health as a factor. “Wild pollinator declines are increasingly linked to pesticide exposure, yet it is unclear how intraspecific differences contribute to observed variation in sensitivity, and the role gut microbes play in the sensitivity of wild bees is largely unexplored,†the authors explain. “Here, we investigate site-level differences in survival and microbiome structure of a wild bumble bee exposed to multiple pesticides, both individually and in combination.†In collecting 175 individuals of this wild, foraging species from an alpine meadow, a valley lake shoreline, and a suburban park and exposing them to a diet with individual pesticides and mixtures, the researchers assess the varying lethal and sublethal effects that can occur with pesticide exposure. Between the three sites, the survival differences “emphasize the importance of considering population of origin when studying pesticide toxicity of wild bees†and highlight how pesticide sensitivity not only varies between species but within individuals of the same species with . . .

(Beyond Pesticides, July 17, 2025) The widespread use of pesticides year-after-year, decade-after-decade, has been found to lead to unintended consequences not only for public health but also for broader ecosystem stability and biodiversity. These impacts include potential nontarget harm through adverse developmental and reproductive effects on the vinegar fly, Drosophila melanogaster, the subject of a peer-reviewed study in Royal Society Open Science. The authors, who studied the organochlorine fungicide chlorothalonil, conclude, “Chlorothalonil exposure decreases larval survival, extends developmental duration and reduces fecundity.†“Even at the lowest tested concentration, chlorothalonil exposure resulted in reduced body weight, ovariole count and egg production compared with non-exposed individuals,†the researchers find. This study builds upon years of scientific research findings and critiques of existing federal pesticide law, as well as the U.S. Environmental Protection Agency’s (EPA) failure to fully assess the adverse impacts on biodiversity and ecosystem stability during the pesticide registration review process. Methodology and Background The goal of this study is to evaluate the health impacts on a nontarget insect species (Drosophila melanogaster) from chronic exposure to chlorothalonil. This specific fungicide was chosen for various reasons, including its wide use across cereals, vegetables, and fruits; . . .

(Beyond Pesticides, July 16, 2025) A study following a mass mortality event of approximately 200 monarch butterflies (Danaus plexippus plexippus) in Pacific Grove, California, highlights the role of pesticides, synthetic pyrethroids in particular, in causing lethal and sublethal effects to nontarget organisms. The research, published in Environmental Toxicology and Chemistry, detects residues of 15 pesticides and associated metabolites in the bodies of 10 deceased butterflies collected from the January 2024 event that occurred near an overwintering site frequented by monarchs. “On average, each monarch butterfly contained 7 pesticides,†the authors report. They continue, “Notably, three pyrethroid insecticides—bifenthrin, cypermethrin, and permethrin—were consistently detected at or near each chemical’s lethal dose (LD50).†LC50, or Lethal Concentration 50, values represent the concentrations of chemicals lethal to 50% of a test population. To assess pesticide residues within ten of the deceased butterflies, the researchers use liquid and gas chromatography with tandem mass spectrometry (LC-MS/MS and GC-MS/MS) and find “a total of 15 pesticides and associated metabolites in the butterflies, including 8 insecticides (plus 1 associated metabolite), 2 herbicides (plus 2 associated metabolites), and 2 fungicides.†The study “present[s] evidence that the mortality incident at the Pacific Grove Monarch . . .

(Beyond Pesticides, July 15, 2025) A study published in Environmental Science and Technology finds that there are 47 current-use pesticides—products with active ingredients that are currently registered with U.S. Environmental Protection Agency (EPA) —detected in samples of indoor dust, drinking water, and urine from households in Indiana. This study builds on existing scientific literature documenting the public health threat of nonoccupational, indoor pesticide exposure. (See previous Daily News here, here, and here.) The study is a reminder that pesticides move into the indoor environment through the air, and on clothing, making exposure more widespread than the assumptions used in regulatory reviews. Background and Methodology “In this study, we collected matched samples of indoor dust, drinking water, and urine from 81 households in Indiana, United States, and analyzed these samples for 82 CUPs [current use pesticides], including 48 insecticides, 25 herbicides, and 9 fungicides,†say the authors. They continue: “Of these, 47 CUPs were identified across samples of indoor dust, drinking water, and urine with median total CUP (∑CUP) concentrations of 18 300 ng/g, 101 ng/L, and 2.93 ng/mL, respectively.†The herbicides (13) detected include 2,4-D (2,4-dichlorophenoxyacetic acid), Alachlor, Atrazine, CIAT (Desethyl-atrazine), Diuron, Metolachlor, Metolachlor OA (Oxanilic acid), OIAT . . .

Peter Hopewood, MD, FACS, writing in a bulletin in the American College of Surgeons says, “The coronavirus 2019 (COVID-19) pandemic has been in the healthcare spotlight since 2019, but the reality is that heart disease and cancer killed more people than COVID-19 in 2020 . . . and were our nation’s leading causes of death for decades before that. Among Americans younger than 85 years of age, cancer remains the leading cause of death.†Dr. Hopewood is convinced that “cancer has been an ongoing pandemic since life expectancy increased during the 20th century.â€Â  In 1985, Imperial Chemical Industries and the American Cancer Society declared October “Breast Cancer Awareness Month†as part of a campaign to promote mammograms for the early detection of breast cancer.

(Beyond Pesticides, July 11, 2025) Pesticides and antibiotics are linked inextricably in the looming crisis of human and ecosystem health. Both started out as quasi-miraculous solutions to age-old human problems, yet it has been clear that the failures of each present severe challenges—and that they are synergistic because they trigger the same kinds of defensive mechanisms in their targets: insects, fungi, and weeds on the one hand, and microbes on the other. A review of contamination of waterways in India with pesticides and antibiotics, published in Environmental and Geochemical Health, recounts the many threats that arise when these chemicals mix and how their presence in water makes the problems much worse.   Globally, about five million people died in 2019 from infections with antibiotic-resistant microbes. By 2050, according to a World Bank estimate, antibiotic resistance could add $1 trillion to global health care costs and subtract $3.4 trillion from annual global gross domestic product. While the world slowly realizes the urgent need to counter antibiotic resistance, the role of pesticides in generating it has received less political and public attention. But there is no doubt that pesticides are strongly implicated. In fact, the . . .

(Beyond Pesticides, July 10, 2025) A study in People and Nature, with the goal of better understanding the social acceptability of introduced species management (ISM), often labeled “invasive species,†in the U.S., “conducted an online experiment with vignettes describing hypothetical but realistic ISM scenarios, varying targeted taxon (insect or plant), control method (mechanical, chemical and biological), risk severity (low and high) and type of non-target risk (to humans or native species).†This study highlights the debate on defining “invasive†species, as well as the low levels of acceptability by the general public for chemical controls such as pesticides. In addition, as pesticide hazards increase, the authors note that the responses show acceptance for only mechanical controls that incorporate manual removal of species, such as through pulling, cutting, clipping, or mowing. “Surprisingly, there was no significant difference in how respondents ranked risks to people and risks to native species,†the researchers report.
