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

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

(Beyond Pesticides, November 26, 2024) A study in Environment International finds that young children who exhibit higher levels of pesticide metabolites in their urine show more pronounced neurobehavioral problems at the age of ten. Researchers in China document how exposure during early childhood, especially during the sensitive window before the age of two, is linked to hyperactivity/inattention problems such as attention deficit hyperactivity disorder (ADHD). While adding to the body of science connecting pesticide exposure to learning and developmental disorders, this study offers a “novel perspective on characterizing the fluctuation in repeated measurements of multiple environmental chemicals and identifying the potential critical windows,” the authors share. (See previous Daily News coverage here, here, and here.) The researchers analyze data from questionnaires and urine samples through the ongoing Sheyang Mini Birth Cohort Study (SMBCS), which is a long-term prospective cohort study that associates environmental chemical exposure during pregnancy and childhood to negative health effects. This data addresses combined pesticide exposures in young children with neurobehavior analyses at the age of ten to determine any correlation. Within the SMBCS, a total of 1303 pregnant women are enrolled. When the children reached ages one, two, three, six, seven, eight, nine, and ten years […]

(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 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 12, 2024) With revelations reported last month by Investigate Midwest and previously by The Guardian showing that Syngenta, the manufacturer and registrant of paraquat, kept secret scientific information on the weed killer’s adverse effects related to Parkinson’s disease, there is increasing concern that endocrine-disrupting properties have not been fully disclosed. Endocrine-disrupting synthetic chemicals, derived from fossil fuels, will be the focus of Session 2 of Beyond Pesticides 41st National Forum: Imperatives for a Sustainable Future on Thursday, November 14 from 1:00-3:00pm (EST). Keynote Speaker The keynote speaker, Tracey Woodruff, PhD, will address the scientific, health, and regulatory issues associated with societal reliance on these chemicals. Dr. Woodruff, a former U.S. Environmental Protection Agency (EPA) senior scientist and policy advisor, is the director of the Program on Reproductive Health and the Environment, and professor in the Department of Obstetrics, Gynecology, and Reproductive Sciences in the School of Medicine at the University of California San Francisco. Roundtable Discussion Dr. Woodruff’s talk will be followed by a roundtable with panelists, including a former senior scientist focusing on ecosystem effects, a breast cancer activist, and a farmworker advocate who will share their experience and insight into both the regulation of hazardous materials […]

(Beyond Pesticides, November 8-11, 2024) On Veterans Day 2024 we honor those who have served the country and allies. In the 117th (2021-2022) U.S. Congress, legislators enacted The Sergeant First Class Heath Robinson Honoring Our Promise to Address Comprehensive Toxics Act of 2022 (PACT Act). Since the law passed just over two years ago, there has been just under 1.3 million total approved claims marking a roughly 75% approval rate for PACT Act related claims, according to Department of Veteran Affairs (VA) accounting of progress between August 10, 2022, and October 12, 2024 through its dedicated bimonthly VA PACT Act Performance Dashboard. The legacy of toxic burn pits (open air areas where the military has burned toxic waste) and other avenues for toxic exposure in military bases oversees, as well as within the United States in Hawai’i (See coverage on asbestos exposure continuously impacting veterans, as reported on by Honolulu Civil Beat) and Puerto Rico (See peer-reviewed literature review here on toxic heavy metals in International Journal of Environmental Research and Public Health), among other areas, comes at a time when the country assesses the ongoing impacts of a history that has been characterized by critics as colonial or imperialist.

(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 4, 2024) The U.S. Environmental Protection Agency (EPA) last week opened a public comment period on the regulation of endocrine-disrupting pesticides, a proposal that lays out a drawn-out 10-year process that is narrow in evaluating the underlying mechanism that causes endocrine disruption. The proposal, published in the Federal Register as a partial settlement agreement and consent decree, responds to a lawsuit filed by farmworker and health groups challenging the agency’s failure to test and regulate endocrine-disrupting pesticides. Earlier in the year, after over 25 years of delay following the 1996 Congressional mandate to determine whether pesticides disrupt the endocrine system of humans and other organisms, EPA issued a proposal for modifying its approach to the implementation of the Endocrine Disruptor Screening Program (EDSP). The National Institutes of Environmental Health Sciences explains endocrine disruptors this way: “Endocrine-disrupting chemicals (EDCs) are natural or human-made chemicals that may mimic, block, or interfere with the body’s hormones, which are part of the endocrine system. These chemicals are associated with a wide array of health issues. . . Endocrine glands, distributed throughout the body, produce the hormones that act as signaling molecules after release into the circulatory system. The human body is […]

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

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

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

(Beyond Pesticides, October 22, 2024) A recent study, published through the American Chemical Society, analyzes pesticide contamination in riparian soil and plants as a result of flooding from streams in Germany. The authors hypothesize, and then prove, that frequently flooded sites have higher levels of pesticides present due to the pesticides in surface waters contaminating the soil. Results show that the plant vegetation in the contaminated soil then takes up the pesticides, which bioaccumulate and lead to higher contamination that can further cascade throughout the ecosystem and affect terrestrial food webs. “[O]ur study provides evidence from the field that nontarget plant species typical for riparian stream sites receive considerable pesticide exposure via flooding events,” the authors share. This exposure, and subsequent bioaccumulation in plants, threatens the food web, as many riparian plants are a vital food source for insects. According to the authors, flooding events, and their impact on pesticide contamination within soil and plants, are rarely investigated. This study, “measur[ing] 98 pesticides and metabolites in plants and root-zone soils sampled at five streams situated in an area in Southwest Germany characterized by intensive agricultural land use,” highlights the differences in contamination between frequently flooded and rarely flooded areas and […]

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

(Beyond Pesticides, 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 8, 2024) A comprehensive literature review in Endocrines, published in September, amasses hundreds of studies on endocrine-disrupting chemicals (EDCs) that showcase adverse effects on growth, development, reproduction, and metabolism. The authors, a team of scientists and academics from Brazil, shed light on the link between EDC use and thyroid dysfunction, leading to increasingly prevalent illnesses and deadly diseases. EDCs are any synthetic or natural compounds that hinder endocrine system functions and create harmful effects on organisms. These chemicals can impact the thyroid gland, which is vital in producing hormones and plays a role in several body functions. As the researchers state, “Several EDCs have been classified as thyroid disruptors, impairing thyroid hormone [TH] production, synthesis, metabolism, transport, and/or actions. Notably, thyroid disorders are the second most prevalent endocrine disease worldwide, with incidence increasing significantly in recent years.” The authors continue, “[S]tudies have correlated this rise in thyroid dysfunctions and cancers with increased exposure to EDCs. Although many EDCs are linked to thyroid dysfunction, this review focuses on the deleterious effects of plasticizers, organochlorine pesticides, and per- and poly-fluoroalkyl substances on thyroid function. These contaminants are commonly found in food, water, and everyday products.” This review helps […]

(Beyond Pesticides, October 2, 2024) A comprehensive literature review in Ecotoxicology and Environmental Safety links a heightened risk of spontaneous abortion (SAB) with pesticide exposure. “The strengths of our study include being the first systematic review and meta-analysis to explore the association between exposure to pesticides and the risk of SAB,” the authors say. This novel approach includes analyzing 18 studies, totaling 439,097 pregnant participants, that allows the researchers to highlight an important public health issue and raise concerns for maternal contact with the harmful chemicals in pesticide products. SAB, also known as spontaneous miscarriage, is defined as the loss of pregnancy occurring prior to 20 weeks of gestation. “It has been observed that approximately 10–15% of pregnancies end up terminating spontaneously,” the researchers report. According to the authors, these negative birth outcomes can be attributed to many factors such as advanced maternal age, anatomical, immunological, and endocrinological disorders, infections, tobacco use, alcohol intake, abnormalities of the placenta, and exposure to heavy metals, radiation, and pesticides. To connect SAB specifically to pesticide exposure in mothers, a literature search was conducted for peer-reviewed studies that include pregnant study participants, ages 16 and above, who report “exposure to one or more pesticides […]

(Beyond Pesticides, September 26, 2024) DNA damage is significantly higher in Latinx children from rural, farmworker families than children in urban, non-farmworker families, according to a recent study published by French and American authors in the journal Exposure and Health. Not only do farmworker children test positive for organophosphate pesticides more frequently than non-farmworker children, but the study finds that farmworker children also experience an increased frequency of DNA damage associated with the presence of organophosphate exposure. These results highlight the disparities in exposures and outcomes for children from vulnerable immigrant communities. Advocates note that as long as pesticides remain in use, farmworkers and their families will continue to shoulder a disproportionate share of the toxic effects of these chemicals (see here, here, and here); another in a long line of reasons to shift away from toxic synthetic pesticide use to the adoption of proven organic, regenerative agricultural practices. (See here, here, and here). Methodology The study assesses pesticide exposure and DNA damage in 45 Latinx children ages 10 to 12 from rural, farmworker families (30) and urban, non-farmworker families (15). Participants were selected from a larger study, Preventing Agricultural Chemical Exposure (PACE5)—a community-based research project by the North Carolina […]
