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

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

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

(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 22, 2025) A study published in May by Nature Reviews Endocrinology warns that endocrine-disrupting chemicals (EDCs)—substances that lead to disruption of the endocrine system in an organism—are driving a rapid rise in female reproductive disorders. While EDCs encompass many different forms of chemicals, such as plastic additives, cigarette smoke, and paracetamol, pesticides are among the most common EDCs. The review pays special attention to pesticide classes such as per-and polyfluoroalkyl substances (PFAS) and organochlorines to evaluate how they derail ovarian development, puberty timing, and hormonal balance across the entire female lifespan. Many pesticides are fluorinated, and therefore classified as PFAS. Background Pesticides represent one of the largest sources of EDC exposure. Many persistent organic pollutants (POPs) are resistant to degradation and are capable of bioaccumulating in the food chain, which leads to these harmful chemicals being found in human adipose tissue. The study notes that these chemicals have also been detected in human blood, breast milk, follicular fluid, and other biological samples, explaining their prevalent presence in the human body. The review emphasizes that humans are exposed to a mixture of EDCs across their lifespan, yet current U.S. regulatory strategies do not fully account for combined lifetime […]

(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 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 14, 2025) With the rise in early onset cancer rates and mortality for breast, pancreatic, and gastric cancers, a wide and growing body of science linking pesticides to cancer, and associations between childhood cancer and pesticides, Beyond Pesticides is urging nationwide efforts to eliminate the use of cancer causing pesticides. Peter Hopewood, MD, FACS, writing in a bulletin in the American College of Surgeons says, “The coronavirus 2019 (COVID-19) pandemic has been in the healthcare spotlight since 2019, but the reality is that heart disease and cancer killed more people than COVID-19 in 2020 . . . and were our nation’s leading causes of death for decades before that. Among Americans younger than 85 years of age, cancer remains the leading cause of death.” Dr. Hopewood is convinced that “cancer has been an ongoing pandemic since life expectancy increased during the 20th century.”  In 1985, Imperial Chemical Industries and the American Cancer Society declared October “Breast Cancer Awareness Month” as part of a campaign to promote mammograms for the early detection of breast cancer. Unfortunately, most of us are all too aware of breast cancer. Detection and treatment of cancers do not solve the problem. A preventive approach is needed, not just awareness. Barbara Brenner, […]

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

(Beyond Pesticides, July 3-4, 2025) On this Independence Day, Beyond Pesticides calls for holistic solutions that, as articulated in the Declaration of Independence, move the nation to ensure “certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.” The founders of the United States were aware of the existential threat of corruption to democratic institutions. Alexander Hamilton, the first Secretary of the Treasury, warned in Federalist No. 68 of The Federalist Papers that the presidency could be overtaken by a despotic figure without adequate safeguards. James Madison, the fourth president of the United States, in Federalist No. 10 speaks to the danger that factions—defined as a group of people or entities “… who are united and actuated by some common impulse of passion, or of interest, adversed to the rights of other citizens, or to the permanent and aggregate interests of the community”—impose on the general public, if not checked by safeguards in the country’s political system. The foundational principles in the Declaration of Independence and the Constitution have been challenged under the current administration and in the U.S. Congress. Communities are facing a fourfold attack on these principles and the centuries-old promise of the nation: […]

(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, 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 24, 2025) As changes in the executive branch of the federal government upend expectations among environmental stakeholders, the regulation of food safety in the United States is being revealed as a rickety structure built over a century with unpredictable and sometimes contradictory additions, extensions, remodels, and tear-downs. In the short term, clarity is unavailable, but there have been calls for revision and strengthening of regulatory processes—requiring lawmaker and regulator willingness to incorporate the vast body of evidence that pesticides do far more harm than good, and that organic regenerative agriculture is the surest path to human and ecological health. News reports out of Costa Rica in May brought public attention to drafted legislation to ban pesticides in the country that the World Health Organization (WHO) has defined as “extremely or highly hazardous, or those with evidence of causing cancer, genetic mutations, or affecting reproduction, according to the Globally Harmonized System (GHS).” The headline sparked a relook in this Daily News at the current and historical failure of U.S. policy, which allows cancer-causing pesticides in food production and land management, despite the booming success of a cost-effective and productive, certified organic sector for which petrochemical pesticides are not […]

(Beyond Pesticides, June 19, 2025) Juneteenth, officially recognized as a federal holiday since 2021, commemorates the arrival of Union soldiers in Galveston, Texas, to free enslaved people per the Emancipation Proclamation that was issued two and a half years prior. While June 19, 1865, does not mark the legal end of slavery nationwide, it was a crucial moment in the fight for freedom and continues to highlight the ongoing fight for human rights, equality, and environmental justice.  As Beyond Pesticides has previously shared in the Daily News, this commemorative day is a time for individuals and organizations to acknowledge and reflect on their past and current actions or inactions that perpetuate systemic racism. The father of environmental justice, Robert Bullard, Ph.D., defines environmental racism as any policy or practice that unequally affects or disadvantages individuals, groups, or communities based on their race. Dr. Bullard states that, until the 1980s, environmental conservation and pollution were separate. Many environmental organizations prioritized the preservation of “wilderness” rather than urban areas, predominantly comprised of POC, who continuously experience the disproportionate impacts of pollution and the effects of environmental racism.  Sharing the Science A recent study regarding the intersections of urban planning, wildlife management, […]

(Beyond Pesticides, June 17, 2025) Funding cuts in the current budget bill include drastic cuts in research essential to protect farmers, farmworkers, and their families. There are many federal agencies funding research, but among the most important of those funding research affecting farmers, farmworkers, and their families are the U.S. Environmental Protection Agency (EPA) and the National Institute for Occupational Safety and Health (NIOSH).  >> Tell Congress to restore funding that protects the health of farmers, farmworkers, and their families. EPA funding for the Bioecological Center for Research on Children’s Health (BeRCH) project was cut after almost two years. This project had the potential to address farmworker children’s health. Farmworker children can face many challenges–including poverty, language barriers, inadequate housing, discrimination, fear of family separation, exposure to agricultural chemicals, food insecurity, and migration. BeRCH was designed to identify, understand, and address the cumulative impacts on the health, development, and growth of farmworker children. The project goals were to examine farmworker children’s exposures to environmental toxins (pesticides, heavy metals, particulate matter) and non-chemical psychosocial stressors (poverty, food insecurity, trauma, discrimination, etc). Working in collaboration with the Florida State University (FSU) health clinic in Immokalee, the project would have examined threats, implemented strategies to improve health outcomes for farmworker children, and collaboratively established […]

(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 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, May 29, 2025) A study, published in Environmental Toxicology and Pharmacology, “investigates genotoxic effects on farmers in ParaĂba, 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 23-26, 2025) This Memorial Day, while honoring and mourning the U.S. military personnel who have died serving in the United States Armed Forces, Beyond Pesticides recognizes those who are still fighting the long-term impacts of exposure to toxic chemicals as a result of their use in warfare. A recent review in the Open Journal of Soil Science acts as a reminder of the effects that span multiple generations to both the environment and human health following the use of pesticides. The review analyzes the history and impacts of herbicide use during the Vietnam War, as well as emphasizes the importance and relevance for current and future generations. As the authors state, “The United States (U.S.) and other countries, including Russia and Ukraine, need to learn the historical lessons from the U.S. use of herbicides, containing dioxin TCDD and/or arsenic (As), as chemical weapons during the Vietnam War.” As previously reported by Beyond Pesticides, public attention generally focuses on the “rainbow herbicides,” particularly Agent Orange, used during the Vietnam War; meanwhile, it is the dioxin TCDD (2,3,7,8 tetrachlorodibenzodioxin), a byproduct of Agent Orange’s manufacturing process, that has caused the most lasting damage within the country. While the breakdown […]

(Beyond Pesticides, May 22, 2025) A medical study published in the Journal of the American Medical Association (JAMA) finds that “living within 1 mile of a golf course was associated with 126% increased odds of developing PD [Parkinson’s Disease] compared with individuals living more than 6 miles away from a golf course.” While organic land management offers a simple solution, current pesticide restrictions do not address chronic neurological diseases such as Parkinson’s Disease, which are linked to pesticide exposure. It has become increasingly clear that viable and cost-effective land management practices, including for golf course management, are critical to the protection of community health. Yet, the federal regulatory agencies, including the U.S. Environmental Protection Agency (EPA) and U.S. Food and Drug Administration (FDA), do not conduct an alternative practices assessment as part of their review process to determine whether the risks are “reasonable” (statutory language) or the risk assessments accept an unnecessary hazard. The complexity of pesticide exposure, which includes mixtures of multiple chemicals and undisclosed hazardous “inert” ingredients, raises broad questions about the threats to public health as well as biodiversity. See a recent Action of the Week, FDA Must Establish Tolerances for Pesticides Used in Mixtures, to see […]
