(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 organisms. PFAS in agriculture represents a […]

(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 authors of the current study, in exposing two […]

(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. The Need for Court Action in the Face of EPA Dismantling With the massive dismantling of U.S. Environmental Protection Agency (EPA) programs by the current administration, the appropriations bill provision limits court oversight, […]

(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. Update from July 23, 2025, at 10 AM: The FY26 Interior-Environment Appropriations Bill passed out of […]

(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 site-specific impacts. (See previous Daily […]

(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; evidence linked to adverse health effects on […]

(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 overwintering site was likely caused by […]

(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 (2-Hydroxy-4-isopropylamino-6-amino-s-triazine), OIET […]

(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 resistance of microbes to antibiotics is no […]

(Beyond Pesticides, July 9, 2025) Policymakers in Tanzania are calling for increased investments in organic agriculture for the 2025/26 fiscal year budget, demonstrating the increase in political will to advance new systems of farming and land management after decades of relying on Green Revolution-style, or chemical-intensive, policies. On June 20, various ministers representing the national government presented speeches to Parliament on the national government’s plan and budget recommendations, as well as highlighting the previous fiscal year’s trends and use of funds.   Political and popular support for organic agricultural systems has gained momentum across the globe. Worldwide, organic farming practices quadrupled from 2000 to 2018, with over 180 countries supporting a global transition to organic agriculture. Newly published global survey data by the Research Institute of Organic Agriculture (FiBL) and International Federation of Organic Agriculture Movements – Organics International (IFOAM) reveal global organic agriculture to be at an all-time high, with 71.5 million hectares of farmland in production as of 2020. (See Daily News here). Farmer and agricultural cooperatives around the world, from Brazil to Madagascar and Togo, leverage organic systems to develop competitive business models in regional, national, and international markets. (See Daily News here.) The European Union, with […]

(Beyond Pesticides, July 2, 2025) An article in The New Lede, entitled Seeking answers to a cancer crisis in Iowa, researchers question if agriculture is to blame, documents case studies of cancer diagnoses linked to chemical-intensive agriculture. Current national cancer rates, according to the American Cancer Society, show that two million new cancer cases are projected to occur during 2025 in the U.S. Additional research predicts 618,120 cancer deaths this year as well, highlighting a crisis of great concern. A wide body of science links increased cancer risks with exposure to agricultural chemicals, including petrochemical pesticides and synthetic fertilizers. Previous coverage from Beyond Pesticides showcases the disproportionate health risks to farmworkers and their families, as well as those living near agricultural fields, associated with exposure to harmful toxicants. Recent research ties pesticide use to cancer diagnoses among farmer populations through a literature review of clinical trials, as well as epidemiologic, case-control, and experimental studies, from not only the U.S. but Brazil, India, France, Egypt, Columbia, Ecuador, Mexico, Italy, and Spain. (See Daily News here.) Additional risks for children, as reported in a study in GeoHealth, are noted in Nebraska as exposure to agricultural mixtures show statistically significant positive associations with […]

(Beyond Pesticides, July 1, 2025) Published in Water Research, a study highlights the various routes for pesticide contamination, with the results identifying the presence of over 80 substances in streams without adjacent agricultural land use. “Our findings underscore the necessity of further investigating the non-agricultural entry pathways of pesticides and biocides to effectively mitigate their impacts on streams in non-agricultural catchments,” the authors state. They continue, “These streams often serve as critical refuge habitats and sources of recolonization, making their protection essential for biodiversity conservation.” In analyzing nonagricultural streams, the researchers find pesticide contamination that, while lower than levels found in streams directly next to agricultural land, can occur through various routes and threatens biodiversity in essential ecosystems. As the authors describe: “Although pesticide concentrations were lower than in agricultural streams, the potential toxicity of pesticides was associated with a significant reduction in sensitive insect populations, as indicated by the SPEARpesticides index. Notably, 40% of the studied streams did not achieve a good status according to the pesticide specific SPEARpesticides indicator.” The SPEARpesticides indicator is used “to identify pesticide effects on the aquatic invertebrate community. It measures the abundance of pesticide-sensitive species (“species at risk”) in relation to the abundance […]

(Beyond Pesticides, June 27, 2025) An article in The New York Times (NYT), entitled “A Killer Within Easy Reach,” highlights the use of the weed killer paraquat, a widely used herbicide in the U.S. and many other parts of the world despite being banned in over 70 countries, as the cause of numerous suicides. The article references the tiny nation of Suriname, located on the northeastern coast of South America, as they have “one of the highest suicide rates in the world,” with the majority of those deaths involving paraquat. Globally, paraquat is prevalently used in self-harm incidents. The chemical, when absorbed into the body, among other deadly effects, causes pulmonary fibrosis, making lung tissue brittle and causing respiratory failure. While this pesticide is intended and generally used for weed control, it is also highly lethal to humans in small amounts and is often easily accessible in many households. As the NYT article states, “Pesticides are among the leading means of suicide in agricultural areas of developing nations, implicated in more than 100,000 deaths annually.” Citing examples from around the world, the article states, “Sri Lanka’s crop yields had surged after the introduction of modern fertilizers and pesticides in the […]

(Beyond Pesticides, June 25, 2025) A United Kingdom (UK) study, published in May by the Women’s Environmental Network (Wen) and Pesticide Action Network (PAN) UK, is reporting levels of the herbicide glyphosate—a probable human carcinogen that is also linked to Parkinson’s disease—in tampons at concentrations 40 times higher than the legal drinking water limit. This finding highlights the serious public health threats that result from under-regulated period products, given that 1.8 billion people worldwide menstruate monthly, according to UNICEF.   The report raises fundamental concerns about the harm to women’s health associated with toxic chemical exposure. For tampon users, the vaginal route of exposure bypasses detoxification with a significantly higher absorption rate than skin. In addition, health concerns extend to ongoing chronic toxic chemical exposures to women worldwide working in cotton production and living in nearby communities. Methodology To investigate whether menstrual products contain harmful pesticide residues and whether current safety standards adequately control the risk of vaginal exposure, study researchers tested 15 boxes of tampons directly bought from UK supermarkets. These boxes were sent to an external laboratory for testing that looks for the presence of glyphosate and its breakdown product amionomethylphosphoric acid (AMPA) in the cotton material used to […]

(Beyond Pesticides, June 13, 2025) A report highlights the ongoing stress to the Chesapeake Bay Watershed from pollutants, particularly pesticides. The Chesapeake Bay is the largest estuary in the contiguous United States, with tributaries shared among six states and the District of Columbia. It receives runoff from nine major river systems traversing a wide mix of land uses, with significant agricultural and urban areas nearest the Bay and forest along the western boundary. Nearly 13 million people get their drinking water from the watershed. The watershed report by the Maryland Pesticide Education Network focuses primarily on the herbicide atrazine, the neonicotinoid insecticide thiamethoxam, and per- and polyfluorinated compounds (PFAS). Atrazine needs little introduction, being notorious for disrupting hormones, particularly estrogen, as demonstrated by the pioneering work of Tyrone Hayes and more recent research analyzed by Beyond Pesticides here, here and here. In male fish, it can trigger production of egg proteins, especially vitellogenin, and development of eggs in their testicles. These are manifestations of intersex, in which an organism shows forms of sexual differentiation of both sexes. The Chesapeake watershed report notes that atrazine and metolachlor (also an estrogen/androgen disruptor and suspected human carcinogen) occur together frequently in the Chesapeake […]

(Beyond Pesticides, June 11, 2025) Researchers developed a novel tool* in a recent study published in Nature Communications this year that successfully creates a map of the “pesticide-gut microbiota-metabolite network,” identifying “significant alterations in gut bacteria metabolism.” While the study authors acknowledge that this is not a complete map, since they selected specific pesticides and bacterial partners, the research adds to the body of peer-reviewed scientific literature that underscores the relationship between pesticide residues and human gut health. Organic farmers, as well as any land steward invested in agroecological practices and soil health, understand that microbial life (both in the body and in the soil) is dangerously undermined by the status quo of chemical-intensive land management. Background and Methodology The researchers leverage mass spectrometry to test metabolite (metabolomics) and lipid (lipidomics) relationships with pesticide residues, as well as an in vivo mouse model. *The map itself is a form of computational biology, which advocates have warned could be a false solution if not accompanied by other proven scientific methods. See here for analysis by the Natural Resources Defense Council on risks of unproven methods such as New Approach Methodologies [NAMs]. All major phylogenetic (“evolutionary relationships among biological entities”) groups are […]

(Beyond Pesticides, June 6, 2025) Published in Environmental Pollution, a study of commercial dry pet products finds dietary pesticide residues in dog and cat food, “highlighting the urgent need for improved regulatory frameworks to address the presence of non-approved pesticides in pet food.” Additionally, the researchers point out: “Current regulatory frameworks primarily assess the toxicity of individual pesticide compounds, yet real-world exposure involves complex mixtures that may lead to additive or synergistic effects. The presence of multiple residues in a single sample suggests that companion animals may be subjected to combined toxicological burdens that are not yet fully understood.” (See studies here, here, and here.) The researchers assess pesticide contamination, and their associated toxicological risks, in 83 total food products for dogs (43) and cats (40). Of the foods tested, the researchers found a total of 51 pesticides, many of which are banned in the European Union (EU), including 47% fungicides and 37% insecticides. “Pesticide residues in pet food pose potential risks to animal health, yet their occurrence and dietary exposure in companion animals remain largely unexplored,” the authors state. They continue: “To our knowledge, this is one of the first comprehensive investigations assessing both pesticide prevalence and potential dietary […]

(Beyond Pesticides, June 5, 2025) A study conducted in Pennsylvania and published in Environmental Entomology highlights threats to nontarget organisms from neonicotinoid insecticide exposure. Using species of ground beetles as an example, the study documents sublethal behavioral effects as well as decreased week-long survival. This research fills a notable gap in current research, with the authors explaining, “Predatory soil arthropods are under-represented in insecticide toxicity studies, severely limiting our understanding of how insecticides affect soil-invertebrate communities in agroecosystems.”   The researchers continue, “As a step toward addressing this issue, we conducted novel acute oral, topical, and soil-based toxicity assays on 9 ground beetle species (Coleoptera: Carabidae) in response to the neonicotinoid insecticides clothianidin, thiamethoxam, and imidacloprid.” The nine carabid beetle species, all common to agroecosystems in central Pennsylvania, were exposed to clothianidin, while additional assays with thiamethoxam and imidacloprid were conducted on the two most abundant species. A wide body of science exists that connects neonicotinoid exposure to health effects in a variety of nontarget organisms. Neonicotinoids, a class of neurotoxic insecticides, act as agonists of nicotinic acetylcholine receptors, “persist under field conditions, and are water soluble, enabling them to translocate into plants and provide systemic protection of seedlings,” the […]

(Beyond Pesticides, June 4, 2025) A new study published in Environmental Chemistry and Ecotoxicology finds that “higher pesticide exposure was significantly associated with elevated blood pressure and greater risks of hypertension.” More specifically, “[t]he results indicated that exposure to PNP [para-nitrophenol/parathion] and 2,4-D may contribute to an increased risk of hypertension.” According to data provided by the Centers for Disease Control and Prevention (CDC), roughly half of U.S. adults have hypertension, which can lead to increased risk for stroke and heart disease, two of the top causes of mortality in the nation. Amid worsening public health concerns, with young generations facing an increase in heart failure (see here for the Duke University School of Medicine analysis), advocates continue to call for the transformation of the food system, including increased access and production of whole-based organic food. Background Information and Methodology The authors of this community-based, case-control study are researchers at the Guangzhou Center for Disease Control and Prevention and the School of Public Health at Southern Medical University, both located in Guangzhou, China. The study included 360 participants, consisting of 180 hypertension cases and 180 non-cases (“normotensive individuals”) within China’s National Essential Public Health Services Program. All participants were over […]

(Beyond Pesticides, June 3, 2025) Chemical contaminants in wastewater have long been of concern, especially given the significant costs of upgrading wastewater treatment facilities to remove existing and emerging chemicals. In advancing chemical safety, one of the many regulatory determinations that Beyond Pesticides advocates for, prior to the allowance of any toxic chemical use, is the establishment of a realistic cleanup or disposal strategy. Yet, a plethora of petrochemical pesticides flood the market and contaminate the air, soil, water, and crops before poisoning humans and wildlife. A study in the Journal of Environmental Chemical Engineering uses the detectable levels of metabolites (breakdown products) of pesticides in wastewater to gauge exposure to populations living near flower bulb fields throughout the Netherlands. Wastewater samples were collected from five wastewater treatment plants (WWTPs) located in different parts of the Netherlands, with two of the locations (Tollebeek and Lisse) located near flower bulb fields and the other three representing control areas. The study finds that higher levels of chemicals correlate with proximity to agricultural fields and present a heightened health risk. The authors describe wastewater-based surveillance (WBS) as a complementary approach to human biomonitoring that they use “to assess the spatial differences in human […]

(Beyond Pesticides, May 30, 2025) The Making America Healthy Again (MAHA) Commission report, Make Our Children Healthy Again: Assessment, published on May 23, drew criticism from the pesticide industry and agribusiness allies for pointing to independent science that identifies a range of pesticide-induced health hazards.* The Commission, chaired by Robert F. Kennedy, Jr., Secretary of the Department of Health and Human Services (HHS), is composed of the heads of numerous agencies of the federal government and the White House, from the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), and the Office of Management and Budget (OMB), to the Assistant to the President and Deputy Chief of Staff for Policy Stephen Miller. The MAHA Commission was established by Executive Order 14212 on February 13, 2025. Despite extensive citations to the science on pesticide hazards, the report includes a section on “Crop Protection Tools,” in which there is a repetition of chemical industry talking points that pesticide residues in food comply with existing tolerances, thus implying that pesticides in food are safe. (See USDA Pesticide Data Program Continues to Mislead the Public on Pesticide Residue Exposure.) However, overall the report’s introduction sets a tone that seeks to catalogue […]

(Beyond Pesticides, May 29, 2025) A study, published in Environmental Toxicology and Pharmacology, “investigates genotoxic effects on farmers in Paraíba, Brazil, analyzing buccal mucosa cells [cells from inside the cheek] for DNA and cellular damage,” the authors write. In comparing data from 33 pesticide-exposed agricultural workers to 29 unexposed people in a control group, the researchers report that the “findings revealed significantly higher frequencies of cellular alterations and DNA damage among exposed farmers relative to the control group, with no significant impact from factors such as smoking, alcohol consumption, or family cancer history.” They continue, “These results underscore the genotoxic risks linked to prolonged pesticide exposure and highlight the necessity for stricter regulatory measures.” As Beyond Pesticides documents in Disproportionate Pesticide Hazards to Farmworkers and People of Color Documented… Again, farmworkers have been excluded from labor and occupational safety protection laws since their inception. The Occupational Safety and Health Administration (OSHA) defers all policy on pesticide protections to the U.S. Environmental Protection Agency (EPA), which has been widely criticized for providing inadequate worker protection standards. This study focuses on workers in Brazil, but represents issues that impact communities worldwide. “The agricultural sector plays a pivotal role in Brazil’s economy, encompassing […]

(Beyond Pesticides, May 28, 2025) A study in Birth Defects Research bolsters existing evidence that agricultural workers, and specifically Hispanic workers in California, are disproportionately bearing the burden of pesticide exposure. Caroline Cox, formerly of the Center for Environmental Health in Oakland, and Jonathan K. London, PhD of the University of California, Davis, examine how currently-used agricultural pesticides unequally affect communities along racial and ethnic gradients. Ms. Cox is a member of Beyond Pesticides’ board. Using 2022 data from the California Department of Pesticide Regulation (CDPR) and the U.S. Census Bureau, the researchers analyzed county, census tract, and school district data for the percentage of non-Hispanic White population in each population unit and determined the total agricultural use of commercial formulations of pesticides in the same units. CDPR reporting system’s granular data, including application locations at a resolution of one square mile, and the specific products, dates, and amounts of pesticides used, allows comparison of the data with demographic records. The results show that Hispanics’ exposure status is robust, independent of current or past data or “individual pesticides of public health concern.” Pesticides that harm reproductive health were strikingly concentrated among Hispanic populations. There is abundant evidence of racial and ethnic […]
