(Beyond Pesticides, December 12, 2025) A study concluding that the weed killer glyphosate did not cause cancer was retracted last week after it was revealed in lawsuit documents that the authors did not disclose their relationship with Monsanto/Bayer. The editor-and-chief, Martin van den Berg, PhD of Regulatory Toxicology and Pharmacology, which published the article 25 years ago, wrote in the journal, “Concerns were raised regarding the authorship of this paper, validity of the research findings in the context of misrepresentation of the contributions by the authors and the study sponsor and potential conflicts of interest of the authors.”  The study, titled “Safety Evaluation and Risk Assessment of the Herbicide Roundup and Its Active Ingredient, Glyphosate, for Humans” and coauthored by three researchers in New York, The Netherlands, and Canada, was referred to as a “Landmark glyphosate safety study” in a recent article by U.S. Right to Know.   While this retraction not only sheds light on Monsanto’s influence through ghostwriting, it adds to the wide body of evidence regarding the regulatory deficiencies currently in place. The revelation is a reminder of related incidents in which Monsanto (Bayer) and other companies have wielded excessive influence at the U.S. Environmental Protection Agency (EPA), undermining the integrity of the science needed to inform the regulatory decisions that safeguard health and the environment. (See Daily News Corruption Problems Persist at EPA.)  EPA Deficiencies  In addition to the initial registration process, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires that EPA conduct a registration review of all pesticide […]

(Beyond Pesticides, December 11, 2025) In an amicus brief published on December 1, 2025, the Office of the Solicitor General (SG) and the White House are calling on the Supreme Court of the United States (SCOTUS) to grant certiorari on Bayer’s petition to shield chemical companies that fail to warn people about the potential hazards of their pesticide products. The U.S. Solicitor General D. John Sauer (former Solicitor General of Missouri, home to Bayer-Monsanto’s U.S. headquarters), in siding with the Germany-based, multinational pesticide corporation, calls for SCOTUS to take on the case, which could lead to a prohibition on state-level failure-to-warn claims based on the arguments laid out in the amicus brief. This move sets the stage for SCOTUS to undermine the main legal argument used to hold pesticide corporations accountable for their harmful products, sending Bayer’s stock price to skyrocket 12 percentage points between December 2 and December 3 after the decision was made public. As of May 2025, Bayer has already paid at least 10 billion dollars in jury verdicts and settlements to cancer victims who have attributed their diagnoses to the use of Bayer/Monsanto’s glyphosate-based Roundup weed killer products, according to Lawsuit Information Center. Two previous petitions […]

(Beyond Pesticides, December 10, 2025) On November 21, 2025, the International Agency for Research on Cancer (IARC), a branch of the World Health Organization (WHO), designated the endocrine-disrupting herbicide atrazine (as well as the herbicide alachlor) as “probably carcinogenic to humans.” Manufactured by the multinational, China-based pesticide corporation Syngenta, atrazine has been linked to various adverse health effects and runoff into waterways across the continental United States for years. Tyrone Hayes, PhD, researcher and professor of Integrative Biology at the University of California, Berkeley, who studies the endocrine-disrupting properties of atrazine and other chemicals, has said that atrazine induces cancer by turning on the enzyme aromatase. Dr. Hayes told conferees of Beyond Pesticides’ 31st National Pesticide Forum that: “[W]hat is concerning about aromatase expression and estrogen in mammals is breast cancer and prostate cancer. With regard to prostate cancer, there is an 8.4-fold increase in prostate cancer in men who work in atrazine factories and bag atrazine. There is at least one correlational study, which I didn’t publish, that shows women whose well water is contaminated with atrazine are more likely to develop breast cancer than women who live in the same community, but don’t drink the well water. (Kettles, […]

(Beyond Pesticides, December 9, 2025) In the Journal of Environmental Quality, researchers at the U.S. Department of Agriculture (USDA) report that a 4-year organically managed corn-soybean-oat system reduces nitrogen (N) loads by 50 percent with corn and soybean yields “equivalent to or higher than conventional [chemical-intensive] in most years.” The findings from a 7-year study comparing nitrate loss in organic and chemical-intensive management found that organically managed perennial pasture reduced nitrogen loads significantly. The study, which focused on nitrate pollution in agriculture that harms biodiversity, threatens waterways, drinking water, and public health, and releases nitrous oxide (an extremely potent greenhouse gas), was conducted at USDA’s National Laboratory for Agriculture and the Environment. Organic and regenerative organic farmers and businesses posit that if commodity crops can be grown in organically managed systems with competitive yields, then this supports their argument for alternative systems not only feasible but economically sustainable and responsible. Background and Methodology The researchers note that, in the eastern and U.S. Midwest, “subsurface tile drainage” (the practice of manually draining fields below the surface soil to assist fields that are otherwise challenging to drain due to wet areas/highly compacted soils) has exacerbated nitrogen and nutrient runoff, ultimately leading to diminished soil health. […]

(Beyond Pesticides, December 8, 2025) In response to the Trump administration’s proposed new rules to limit protections for critical habitats under the Endangered Species Act (ESA), Beyond Pesticides is calling for public action to “Tell the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) not to adopt regulations that weaken protection of threatened and endangered species.” According  to environmentalists, four new rules will allow an expansion of oil drilling, logging, and mining in critical habitats. A week before Thanksgiving, which honors habitats supporting life, FWS, part of the Department of Interior (DOI), and NMFS, part of the Department of Commerce, announced proposed revisions to the rules implementing ESA that raises serious questions about the future restrictions of the nation’s foundational environmental law. Passed with bipartisan support in 1973, the ESA establishes “a prohibition on ‘take’ of a species, the requirement that all federal agencies ensure that the actions they carry out will not jeopardize the continued existence of a threatened or endangered species, and the drafting and implementation of recovery plans for at risk species,” according to the National Agricultural Law Center. See ESA current regulations.  Secretary of DOI Doug Burgum describes the action: “This administration is restoring the Endangered […]

(Beyond Pesticides, December 5, 2025) A study published this month in Environmental Pollution analyzes the role of neonicotinoid insecticide exposure on bird populations, finding a significant negative effect of imidacloprid use on insectivorous bird abundance. In comparing the effects of the insecticide imidacloprid on bird abundance in France before and after the 2018 ban, the researchers show a weak recovery of bird populations after 2018. The persistent nature of imidacloprid, however, as well as the continued use of other petrochemical pesticides that have adverse effects on bird species, continues to impact populations of all types of birds and other wildlife, leading to cascading impacts on biodiversity.    “Our study shows that imidacloprid is a major covariate of the abundance of birds, in addition to other pesticides that are also negatively related to bird populations, and that these effects are not uniform across species,” the authors report. They continue in saying that the relationship between neonicotinoids and bird abundance varied across bird diets, as “the abundance of insectivorous birds was consistently lower under increasing pesticide use, in particular imidacloprid.” Background As shared in the study and on Beyond Pesticides’ Birds page, bird species can be exposed to pesticides directly through ingestion […]

(Beyond Pesticides, December 4, 2025) In a news release last week on November 26, 2025, the U.S. Environmental Protection Agency (EPA) “issued a comprehensive fact-check addressing dangerous misinformation circulating about EPA’s recent pesticide approvals” that, according to health and environmental advocates, continues to deceive the public about the true risks for health and the environment from petrochemical pesticides including, but not limited to, per- and polyfluoroalkyl substances (PFAS). Also published on November 26, coverage titled The EPA Is Embracing PFAS Pesticides. These Are The Health Risks in Time further highlights EPA’s deficiencies and the threats of PFAS, which Beyond Pesticides has extensively covered. (See here and here.)  The controversy erupted as a result of EPA’s latest proposal to allow a new fluorinated pesticide to the list of four other similar compounds now widely available for use in homes and gardens, buildings, and agriculture. The newest pesticide proposed for EPA registration, epyrifenacil (agricultural weed killer), joins cyclobutrifluram (soil fungicide/nematicide), isocycloseram (household and agricultural insecticide), diflufenican (lawn and agricultural weed killer), and trifludimoxazin (agricultural weed killer), making a total of five PFAS pesticide proposals this year that have been associated with national and worldwide contamination of food, land, and water. Two of these, cyclobutrifluram and isocycloseram, have been approved. “Instead of constraining the use of fluorinated pesticides—persistent and highly toxic […]

(Beyond Pesticides, December 3, 2025) Childhood cancers are on the rise globally; in the U.S. cancer is the second most common cause of death in children between one and 14 years old, and the fourth most common in adolescents. A recent study of Nebraska pesticide use and pediatric cancer incidence by researchers from the University of Nebraska Medical Center and the University of Idaho Department of Fish and Wildlife Sciences found positive associations between pesticides and overall cancer, brain and central nervous system cancers, and leukemia among children (defined as under age 20). The study’s lead author, Jabeen Taiba, PhD, of the University of Nebraska Medical Center, will discuss the study results on December 4, 2025, at the second session of Beyond Pesticides’ 42nd National Pesticide Forum, The Pesticide Threat to Environmental Health – Advancing Holistic Solutions Aligned with Nature. The first session recordings and materials are available here. The authors’ emphasis on evaluating mixtures, and their innovative technical methods for doing so, highlight the direction environmental health research and regulation must take. Studying pesticides singly is an inadequate approach, according to the authors, because pesticides are not applied individually anymore, but very often in mixtures of herbicides, insecticides, and […]

(Beyond Pesticides, December 2, 2025) A personal and heartfelt message from Jay Feldman, executive director, for the holiday season! During this holiday season, I’m writing on behalf of Beyond Pesticides’ staff and board of directors to wish you a Happy Holiday. We celebrate with you our shared commitment to the values and principles that protect the well-being of people and the ecosystems on which life depends. In reflecting on the steps we are taking at Beyond Pesticides to confront existential health and environmental threats, I believe we, together, are pursuing a meaningful path forward—and I am thankful for that.  If you can, and in honor of Giving Tuesday, please consider a gift sometime during this holiday season on our secure website at bp-dc.org/give2025. Your support of any size makes a tremendous difference! Thank you! Before the specifics, I think it is important to say that with the current challenges being endured by the people of our country and around the world, threats to a sustainable future can be overshadowed by the crises that impede daily survival. At Beyond Pesticides, I am thankful we recognize the immediate support needed in this regard, at the same time that we move ahead with the urgent […]

(Beyond Pesticides, December 2, 2025) Recently published in Reproductive Toxicology, researchers in Denmark and Iceland investigate the impacts of pesticides on sex hormones, finding that “prenatal exposure to [the insecticide] chlorpyrifos and [weed killer] 2,4-D may affect the reproductive hormones in girls, but not boys, during minipuberty, which may have long-term implications.” Based on their analysis of urinary maternal concentrations of the pesticides and their metabolites and hormone levels in infants, the authors report, “This study examined the association between maternal pesticide exposure and pituitary, gonadal, and adrenal hormones in offspring during infancy.” The sex-specific findings highlight a public health concern with potentially long-lasting transgenerational effects. “We recruited pregnant women from 2010 to 2012 in the Odense Child Cohort, including 489 mother-child pairs,” the authors state. They continue: “Maternal urinary concentrations of the generic pyrethroid metabolite 3-phenoxybenzoic acid (3-PBA), the chlorpyrifos metabolite 3,5,6-trichloro-2-pyridinol (TCPY), and the herbicide 2,4-D were measured at gestational week 28. Serum concentrations of luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone (T), estrone (E1), estradiol (E2), 17-hydroxyprogesterone (17-OHP), Androstenedione (Adione), and Dehydroepiandrosterone sulfate (DHEAS) were assessed in infancy.” The results of the analyses show that in girls, higher maternal urinary TCPY and 2,4-D concentrations are significantly […]

(Beyond Pesticides, December 1, 2025) A week before Thanksgiving, and the honoring of critical habitats that support life, the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS) announced proposed revisions to the rules implementing the Endangered Species Act (ESA) that environmentalists say will severely weaken the nation’s foundational environmental law. Passed with bipartisan support in 1973, as an update to earlier related statutes, the law establishes a prohibition “on ‘take’ of a species, the requirement that all federal agencies ensure that the actions they carry out will not jeopardize the continued existence of a threatened or endangered species, and the drafting and implementation of recovery plans for at risk species,” according to the National Agricultural Law Center.” See ESA current regulations. FWS and NMFS describe their proposals as a strengthening of the rules implementing ESA, explaining that they “remove regulatory barriers that hinder responsible resource development and economic growth, including expanded oil exploration. However, environmentalists explain that the proposals undermine the basic protections provided threatened and endangered species and narrow the definition of critical habitats. ESA grows out of a history of respect for the earth that is captured in the Thanksgiving Address (the Ohen:ton Karihwatehkwen) […]

(Beyond Pesticides, November 26-30, 2025) The Beyond Pesticides team and board would like to thank those working in communities across the country and actively working to protect the health of our soil, air, water, and all life. In the spirit of uplifting the intersection of traditional ecological knowledge and science, we would like to share with you some excerpts from Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge and the Teachings of Plants—a collection of essays written by Robin Wall Kimmerer, PhD, founder and director of the Center for Native Peoples and the Environment, professor of environmental biology at the State University of New York (SUNY) College of Environmental Science and Forestry (ESF) in Syracuse, New York, mother, and enrolled member of the Citizen Potawatomi Nation.

(Beyond Pesticides, November 25, 2025) Chemical pollution is having a profound impact on men’s overall health and reproductive function. Endocrine-disrupting chemicals—which prominently include pesticides—are a major factor. The Health and Environment Alliance (HEAL) a European organization funded by the European Union (EU) and several private foundations, has issued a strong call for attention to – and action on – the precipitous decline in male reproductive health owing to chemical exposures, including pesticides. In a new report, Chemical pollution and men’s health: A hidden crisis in Europe, the group states, “The scientific evidence is clear. The costs of chemical pollution – human and economic – are mounting. The solutions exist. What we need now is the political will to act.” The report was written by Rosaella Cannarella, M.D., PhD, an endocrinologist at the Division of Endocrinology, Metabolic Diseases and Nutrition, University of Catania (Italy). HEAL’s report details alarming indications of catastrophe in male reproductive health: prostate cancer, testicular cancer, crashing sperm counts, and numerous developmental problems including cryptorchidism, urogenital malformations, and hypospadias. The report highlights pesticides, microplastics, phthalates, bisphenols, PFAS and heavy metals as the likely environmental sources of the crisis. There is evidence that all of these endocrine disrupting chemicals […]

(Beyond Pesticides, November 24, 2025) In his article on ecological traps, Professor Danilo Russo, PhD, explains the harm caused to wildlife from well-intentioned efforts to establish habitat on chemical-intensive farms or areas otherwise subject to chemical exposure. Dr. Russo et al., in “To improve or not to improve? The dilemma of “bat-friendly” farmland potentially becoming an ecological trap” (2024), write, “[W]hen restoring habitats for bats in conventional farmland, potential unintended outcomes must be considered, particularly if restoration actions are not accompanied by mitigation of key threats. These threats include the persistent and widespread use of pesticides. . .” (See also a study in Environmental Entomology, which shows that habitat and open space near agricultural fields become a killing field of pesticides, threatening biodiversity due to contamination from toxic drift.) As this false sense of protection persists, Beyond Pesticides is calling on governors to adopt policies that support organic land management and ecological balance. Organic practices are, by definition, a systems change that is aligned with nature and the biodiversity protection that is needed. Ecological traps are incremental steps that fail to address underlying systemic problems that allow hazards to persist. While they represent an affirmative action in an attempt to adopt restorative measures, the […]

(Beyond Pesticides, November 21, 2025) “How do we respond when told that the solution to ubiquitous and hazardous toxic chemicals in our lives (in our air, food, water, soil, on farms, in parks, playing fields, and schoolyards) is a reduction in their use that continues to allow unnecessary toxic chemical dependency and poisoning?  Do we accept partial restrictions of pesticide use, despite the availability of cost-effective alternatives that stop the toxic assault and help to prevent the most serious associated diseases that invade and attack our bodies, our loved ones, our families, and our communities—with breast cancer, prostate and testicular cancer, pediatric cancer, infertility, and more?”   These are the questions being asked about the most prevalent cancers in the U.S. and worldwide at the upcoming 2nd Session of the National Forum, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature, scheduled for December 4, 1:00-3:30pm (EST).  ‍️➡️ Link to register The Forum brings together cutting-edge science and medical experts from Brazil, Italy, Belgium, Rwanda, Canada, and the United States to sharpen the voices of advocates who are saying that the time for action to eliminate the current reliance on petrochemical pesticides and fertilizers is past due […]

(Beyond Pesticides, November 20, 2025) Recent scientific literature finds heightened toxicity associated with pesticide metabolites, the transformation/breakdown products of the parent compounds, that threaten the health of the soil, wildlife, and humans. This research stresses the importance of the U.S. Environmental Protection Agency (EPA) evaluating metabolites, which is currently insufficiently included in regulatory processes. In a literature review in Global Change Biology, the researchers point out multiple areas in which regulations fail to address key criteria, including metabolites, saying: “Pesticide risk assessments currently rely on surrogate species and focus primarily on acute lethality metrics, failing to capture the broader impacts on non-target organisms and thus biodiversity. Under the directives of regulatory agencies worldwide, this traditional approach overlooks the complex interactions between multiple stressors, including climate change, land-use shifts, and pesticide transformation products. Pesticide risk assessments must therefore undergo a paradigm shift to account for these complex interactions, which disproportionately affect insect pollinators, other non-target species, and biodiversity at large.” A metabolite is a breakdown product that forms when a pesticide is used in the environment and mixes with air, water, soil, or living organisms. All metabolites fall under the category of transformation products, which is the broader term for any […]

(Beyond Pesticides, November 19, 2025) In the book, Biological Control Systems and Climate Change, published this month, Danilo Russo, PhD—a speaker during the first session of our 42nd National Forum, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature—and other researchers add to the existing literature on the climate change threat to ecosystem services. Dr. Russo’s chapter, entitled “Impact of Climate Change on Bats Involved in Biological Control,” explains one of the lost benefits of ecological balance attributable to the climate crisis. As explained in the book: “In conservation biological control, habitats surrounding and within crops are managed to favour an increase in natural enemy populations while suppressing pest populations. These agroecological systems can be complex, and are affected by climate change.” The ability of climate change to influence the effectiveness of biological control systems is explored, showing the “effects on the large diversity of macro- and microorganisms involved in biocontrol, and the possible increase or decrease in pest outbreaks following changes in characteristics (morphology, physiology, behaviour….), distribution or phenology.” Dr. Russo is a full professor of ecology at the University of Naples Federico II, an international leader in bat research, and coauthor of A Natural History […]

(Beyond Pesticides, November 18, 2025) A study published in Horticultural Plant Journal provides additional evidence on the viability of organically managed farmland based on tomatoes cultivated through traditional plant breeding and regional variances. The authors of the research find that, “Despite the positive trend of the organic sector’s development in Europe, the number of tomato varieties bred for organic farming is still limited since efforts have been mainly focused on high input conditions.” They continue: “As a result, the existing cultivars may not suit to organic production [ ] as cultivars chosen for conventional [chemical-intensive] systems often respond well to chemical fertilizers to improve crop output, but they might not maximize nutrient uptake in organic systems where minor external inputs are provided.” In this context, the marketplace is not maximizing the potential productivity of organic systems due to the limited availability of seeds and plant material best suited to conditions in sync with local ecosystems. The designed methodology, as well as the findings, show that there are opportunities for public investment to support systems that cultivate agricultural products without reliance on petrochemical-based fertilizers, pesticides, and seeds treated with pesticide products and other genetically modified characteristics. For millennia, humans have worked […]

(Beyond Pesticides, November 17, 2025) Beyond Pesticides ramped up its campaign to transition parks, playing fields, and schoolyards to organic land management after the release of a study showing synergistic effects of glyphosate (Roundup) and urea fertilizers on earthworms and soil health. The organization’s network is asking Mayors nationwide to lead the transition, pointing to the inadequacy of the current system of regulating pesticides based on risk assessments of individual chemicals or individual chemical families. Chemicals interact, causing increased impacts on human, ecological health, and biodiversity. Moreover, humans, other species, and the biosphere rarely experience exposure to single chemicals or chemical families; exposure to multiple chemicals is the rule, not the exception.   Synergistic effects associated with the use of the weedkiller glyphosate have been implicated in several studies showing magnified adverse impact in soil organisms and in mixture with other chemicals:  The extensive use of glyphosate is linked to effects on nontarget soil organisms, with the risks to soil ecosystems widely studied. (See here, here, here, here, and here.)   One study shows that frequent application in tropical systems of glyphosate “reduced soil macroarthropod richness by 21% and altered community composition.   “A recent global risk assessment of glyphosate further estimated that 67−93% of soils pose high risks to Collembola [springtails] and 43−67% pose medium to high risks to […]

(Beyond Pesticides, November 14, 2025) A literature review in Ecotoxicology and Environmental Safety finds a sex-specific relationship between pesticide exposure and thyroid cancer, with heightened risks for women. “Thyroid cancer (TC) is one of the most common endocrine malignancies worldwide, yet the association between pesticide exposure and TC has not been systematically summarized,” the authors state. “This study aimed to elucidate the relationship between pesticide exposure and TC, focusing on insecticides, herbicides, and fungicides.” In the U.S., approximately 44,020 new cases and 2,290 deaths are estimated for 2025, according to the American Cancer Society, with thyroid cancer as the ninth most common cancer in women. (See research here.) TC ranks globally as the tenth most common cancer, representing a worldwide threat to both men and women. (See here.) The current study considers scientific literature on thyroid cancer and pesticide exposure by pesticide type to extract data and statistically analyze the link between exposure and risk of TC. The results indicate a positive association between exposure to insecticides, herbicides, and fungicides and thyroid cancer, with the sex-based analysis revealing the risk of TC is higher in females. Study Background and Importance As the researchers write, thyroid cancer “is one of the […]

(Beyond Pesticides, November 13, 2025) A study in Environmental Science & Technology shows that maternal exposure to organophosphate (OP) and pyrethroid insecticides adversely affects newborn health. Through amino acid and acylcarnitine metabolomics (the study of small molecules known as metabolites) with over 400 mother-infant pairs, this research analyzes metabolic pathways linking pesticide exposure to negative birth outcomes. “To our knowledge, this study is the first to reveal the effect of OP and pyrethroid insecticide exposure on neonatal metabolic signatures, which may elucidate a key role of metabolites in insecticide exposure and birth outcomes,” the authors state. In collecting maternal urine samples in the first and third trimesters, as well as neonatal blood samples after birth, OP and pyrethroid metabolites and metabolomic biomarkers are assessed. Notably, the authors report: “Results indicated that third-trimester maternal urinary levels of 3- phenoxybenzoic acid (3-PBA) and diethyl dithiophosphate (DEDTP) were negatively associated with birth weight. Specifically, a one-unit increase in their ln-transformed [natural logarithm form] concentrations was associated with a 1.508% decrease in birth weight for 3-PBA and a 1.366% decrease for DEDTP.” Additionally, the analyses show that OP and pyrethroid exposure is associated with “disrupted neonatal amino acids and acylcarnitine profiles, with patterns varying […]

(Beyond Pesticides, November 12, 2025) A ballot initiative to repeal a local ordinance in Maine that bans most uses of lawn chemicals was rejected by the voters last week by a 10-point margin. The voters of Falmouth, Maine, 55% to 45%, upheld an updated ordinance that was passed by the town council in February 2025 to protect the community’s health and the coastal environment from petrochemical pesticides and fertilizers, sending a strong message that ecological land management in conformance with organic standards is the responsible path, given pesticide-related health threats, biodiversity decline, and the climate crisis. The ordinance being challenged by the ballot initiative updated a 2020 rule with more stringent criteria and restrictions and the goal of ensuring a holistic approach to land management. Maine has become the bellwether nationwide for communities seeking to eliminate the use of petrochemical pesticides and fertilizers on public and private property, including parks, playing fields, open spaces, and yards. When applied, pesticides move off the target site through drift, volatilization, runoff, and leaching, creating community-wide poisoning and contamination. However, unlike Maine and five other states, most state laws preempt local jurisdictions from restricting pesticides. These states have adopted preemption language at the behest […]

(Beyond Pesticides, November 11, 2025) A study published in Cardiovascular Toxicology (July 2025) finds significant associations between Gulf War deployment-related toxic chemical exposure hazards and various adverse health outcomes, including heightened risk of atherosclerotic cardiovascular diseases (ASCVDs), such as “heart attack, coronary heart disease, stroke, transient ischemic attack, and peripheral vascular disease.” While there were no significant associations found directly between pesticide products and these adverse health effects, researchers attribute this to limited sample sizes and wide confidence intervals as part of the study methodology. Further research is necessary to build on this study, given the preponderance of scientific evidence linking pesticide exposure to heightened health risks to the cardiovascular system. On the issue of statistical significance, the authors state the following: “There may be difficulty [for survey respondents] remembering the[ir] military exposure history since the survey was completed nearly 25 years after the Gulf War.” While it is difficult to pinpoint pesticide exposure as a cause of illness among the toxic mixtures to which service members are exposed, there has been recognition by the Veterans Administration (VA) of diseases that are directly related to military service. Beyond Pesticides previously reported that the VA has established 20 burn pit and […]
