Organic Land Management and Conservation Maximizes Wildlife Biodiversity, Adding to Previous Studies

Thursday, June 4th, 2026

(Beyond Pesticides, June 4, 2026) In a study published in Perspectives in Ecology and Conservation, researchers in Brazil find that organic farming coupled with agroecological conservation practices “promote[s] biodiversity in agricultural landscapes.” The proxy for biodiversity in this study is anurans, a type of frog or toad native to the Brazilian Pampa—a section of the South American Pampas grasslands, a globally underrecognized biodiversity hotspot. According to a scientific report reviewed by Mongabay in 2024, “nearly a third of the Brazilian portion…has been lost since 1985, largely to agricultural expansion and forestry plantations.” In the U.S. context, public health and environmental advocates continue to call for the transition to organic land management as a solution that validates the ecosystem services that biodiversity-forward agricultural systems can provide under values-aligned stewardship. Methodology and Main Findings The authors in this study, researchers at the Universidade Federal do Rio Grande do Sul, surveyed 26 artificial ponds across 16 family farms with different land management systems—9 organic farms and 7 conventional farms—located in the Serra do Sudeste region of the Brazilian portion of the Pampa grasslands. All farms were sampled three times during the 2023 to 2024 breeding seasons (twice in the October to November 2023 […]

Public Health Advocates Call for Review of Adverse Synergistic Effects of Pesticides, Ignored by Regulators  

Monday, May 11th, 2026

(Beyond Pesticides, May 11, 2026) As studies stack up on adverse synergistic effects of chemical mixtures, serious deficiencies in the regulatory review of pesticides have come into sharp focus. As the hazards are shown to escalate and the regulatory review process is shown to fall short, public health advocates are telling Congress, the U.S. Environmental Protection Agency, and the Department of Health and Human Services that they must consider the effects of pesticides in the context in which they are used and with reference to the organic alternative.  A recent study in Toxics reviewed the current literature on pesticides, microplastics, or metal exposure in combination with per- and polyfluoroalkyl substances (PFAS) on aquatic vertebrates and invertebrates, finding that PFAS can modify, including intensify, the toxicity of co-occurring pollutants.   A commentary in Frontiers in Toxicology, by  Maricel Maffini, PhD, and Laura Vandenberg, PhD,  notes, “Current approaches also rely on the assumption that testing chemicals one at a time is appropriate to understand how chemicals act under real-world conditions. Numerous mixture studies, including ones that demonstrated cumulative effects, have disproven this assumption.”   As noted by the naturalist, writer, and conservationist John Muir, known as the “Father of the National Parks,” and those before and after him, including the English poet John Donne, […]

Developmental Neurological and Brain Damage in Children Intensifies Call for Ban of Organophosphate Pesticides

Friday, May 8th, 2026

(Beyond Pesticides, May 8, 2026)  A study from Ecuador establishes for the first time the developmental pattern of nervous system toxicants—still widely used in agriculture, mosquito control, and landscaping—on healthy neurological and brain development in children. It is firmly established that widely used organophosphate pesticides are severely toxic to a broad range of organisms. In what’s known as their “classic” mechanism of action, they inhibit acetylcholinesterase (AChE), an enzyme that breaks down the neurotransmitter acetylcholine (ACh), particularly in neuromuscular junctions in the brain. Not enough AChE leads to a buildup of ACh in motor neurons. Organophosphates deplete AChE, and an acute dose can paralyze the heart and lung muscles, causing death. Chronic exposures are implicated in numerous neurodegenerative diseases, including Alzheimer’s, Parkinson’s, and amyotrophic lateral sclerosis (ALS). Beyond Pesticides’ Gateway on Pesticide Hazards and Safe Pest Management has detailed information on the organophosphates malathion, chlorpyrifos, diazinon, and others. Acetylcholine and AChE are vital biological chemicals conserved across the animal kingdom, from humans to insects and everything in between. Yet there is no established baseline for normal levels of ACh and AChE in humans. Comparing biomarkers of organochlorine exposure with normal values would be a major step forward in assessing the influence […]

Habitat Biodiversity Protection, Not Harmed by Pesticides, Key to Mosquito Management

Monday, April 6th, 2026

(Beyond Pesticides, April 6, 2026) While mosquito season is not yet here, Beyond Pesticides has launched an action to remind people and policy makers that mosquito management requires the enhancing of natural ecosystems, including bird populations, in communities and residential areas to reduce the population of these biting insects. The campaign draws on the science showing that an unbalanced ecosystem eliminates some of the most attractive and helpful allies in mosquito management—birds. Incorporating the awareness of healthy ecosystems in communities and yards into local and state policies and practices is a critical pest management tool. The action calls on Governors and Mayors to ensure ecological management of mosquitoes by eliminating the use of pesticides that threaten mosquito predators. An article, “The Ecological Impact of Pesticides on Non-Target Organisms in Agricultural Ecosystems” (2024), captures the importance of land management and habitat to protect a a balance of organisms, including bird populations. The authors, in the context of agroecosystems but generally applicable, write: “Pesticide exposure reduces ecosystem resilience, changes community dynamics, and accelerates population reductions in a variety of organisms, including predatory arthropods, bees, and butterflies. Furthermore, bird populations—which are essential to agroecosystems—face a variety of difficulties as a result of habitat degradation, food […]

Pesticide Exposure Again Linked to Neurotoxic Effects in Humans and Wildlife in Comprehensive Review

Thursday, March 12th, 2026

(Beyond Pesticides, March 12, 2026) The science connecting pesticide exposure to neurotoxicity continues to mount. A study in Discover Toxicology highlights neurotoxic pollutants as significant environmental threats, showcasing the adverse impacts on vertebrates’ neurological health from pesticides, including organophosphates, carbamates, and organochlorines. “These substances disrupt normal neurophysiological functions by impairing neurotransmission, generating oxidative stress, provoking neuroinflammation, and initiating neuronal cell death,” the authors say. They continue, “Such disturbances are linked to cognitive deficits, motor impairments, and abnormal neural development.” Neurological conditions can manifest as headaches, muscle weakness, tremors, paralysis, coordination challenges, vision loss, hallucinations, vertigo, seizures, memory loss, slurred speech, trouble breathing with minimal exertion, and more. The range of adverse effects from low-dose, long-term exposure and low-dose (or subchronic) exposure during developmental phases of life raises serious questions about the adequacy of the regulatory review of pesticides, which focuses on acute high and lethal dose exposure. One study on the neurotoxicity of pesticides, published in Chemosphere, concludes, “New regulatory and preventive measures to mitigate the neurotoxic effects of pesticides are needed.” (See also Daily News.) Even at low concentration, chronic exposure to pesticides and other environmental contaminants “poses serious ecological and health concerns” that occur as these chemicals “bioaccumulate […]

Report Highlights U.S. Cities Facing Pollinator Declines Due to Multiple Pesticide Exposure

Wednesday, October 8th, 2025

(Beyond Pesticides, October 8, 2025) A study, Pesticides detected in two urban areas have implications for local butterfly conservation, published in partnership with researchers at Xerces Society for Invertebrate Conservation, University of Binghamton (New York), and University of Nevada, reports widespread pesticide residues in the host plants of butterflies located in green spaces in the cities of Sacramento, California, and Albuquerque, New Mexico. Just 22 of the hundreds of collected samples had no detectable residues, with all other samples containing some combination of 47 compounds of the 94 tested pesticides in the plant tissue. Of the 47 compounds, 4 are neonicotinoid insecticides linked to adverse effects for bee and pollinator populations based on previous peer-reviewed research. The fungicide azoxystrobin and the insecticide chlorantraniliprole were detected at lethal/sublethal concentrations, according to the report authors. “Residential landscapes have high conservation potential for butterflies and other invertebrates,” says Aaron Anderson, co-lead author of the report and pesticide program specialist at Xerces Society for Invertebrate Conservation. He continues: “But, these findings show how pervasive pesticide contamination can be in towns and cities, and underscore that protecting wildlife in these areas includes addressing pesticides.” The report’s results underscore the pervasiveness of pesticide drift and dispel the myth […]

Review of Scientific Literature Finds All Pesticide Classes Threaten Nontarget Organisms and Biodiversity

Wednesday, September 10th, 2025

(Beyond Pesticides, September 10, 2025) Published earlier this year, a review of over 1,700 studies in Nature Communications finds pesticides affect a diverse range of nontarget organisms and contribute to global biodiversity loss. The authors* reveal “negative responses of the growth, reproduction, behaviour and other physiological biomarkers within terrestrial and aquatic systems” for nontarget plants, animals, and microorganisms. “To our knowledge, there has been no systematic and overarching synthesis of how different types of pesticides affect the diversity of multiple non-target eukaryotic and prokaryotic organisms across all trophic levels,” the researchers write. They continue, “Furthermore, current syntheses have not considered how the impacts of pesticides differ globally across climatic zones or for major mechanisms of exposure, such as those acting in aquatic or terrestrial environments.” In particular, pesticide regulatory risk assessments analyze a limited range of model species, including rats, zebrafish, clawed frogs, honeybees, and earthworms, among others. As such, they are unlikely to capture the variety of responses to pesticide exposure seen across the diversity of species and communities found in both managed and natural systems,” the authors state. *Authors include Beyond Pesticides 2023 National Forum speaker Dave Goulson—see the Daily News on his keynote address here.

Scientific Studies Identify EPA Deficiency in Evaluating Safety of Toxic Chemical Interactions

Monday, September 8th, 2025

(Beyond Pesticides, September 8, 2025) Beyond Pesticides today called on Congress to require the U.S. Environmental Protection Agency (EPA) to incorporate real world science into its evaluation of pesticide safety calculations by recognizing that daily exposure involves multiple chemicals and synergistic interactions— a magnified effect greater than the individual chemical effects added together. The organization cites numerous scientific studies that call public attention to this issue; that a realistic assessment of the human and environmental harm potentially caused by pesticides cannot be evaluated based on single-chemical, single-species tests. Given the numerous complexities associated with this type of assessment, the group points to organic land management in agriculture and residential areas as a more cost-effective approach, sending this message to Congress: EPA must consider the effects of pesticides in the context in which they are used and with reference to the organic alternative. A recent study, covered by Beyond Pesticides in its Daily News, found that the presence of Varroa mites in combination with the neonicotinoid insecticide imidacloprid increases the risk of bee mortality and disrupts the larval gut microbiome. The study found synergy (a greater combined effect) between Varroa destructor, a parasitic mite that attacks and feeds on honey bees, and imidacloprid. The findings were published last […]

Research Highlights Regulatory Failures in Addressing Risks to Nontarget Organisms from Rodenticides

Tuesday, March 18th, 2025

(Beyond Pesticides, March 18, 2025) The November 2024 press release by the U.S. Environmental Protection Agency (EPA) for its Rodenticide Strategy includes the final biological evaluation (BE) of 11 rodenticides. Prior to the finalization of the BE, Beyond Pesticides commented to EPA’s Office of Pesticide Programs in early 2024, disagreeing with the categorical no effect (NE) determinations for all freshwater and marine fish, aquatic mammals, aquatic amphibians, aquatic reptiles, and aquatic invertebrates. (See related Daily News and Action of the Week.) The latest scientific literature highlights the impacts of rodenticides on nontarget organisms, including aquatic organisms that the agency failed to evaluate due to harm that was, as EPA says, “not reasonably certain to occur.” Many rodenticides, intended to target rats, mice, squirrels, nutria, and more, are anticoagulants and stop normal blood clotting. Active ingredients in these pesticides can include bromadiolone, chlorophacinone, difethialone, brodifacoum, and warfarin. Anticoagulant rodenticides (ARs), contrary to the agency’s assertions, can be transported to aquatic ecosystems, including both freshwater and marine environments. As mentioned in Beyond Pesticides’ comments, ARs have been detected in raw and treated wastewater, sewage sludge, estuarine sediments, suspended particulate matter, and liver tissues of sampled fish, demonstrating that the aquatic environment experiences […]

Catastrophic Harm to Women from Pesticides Drives Call for Their Elimination

Monday, March 10th, 2025

(Beyond Pesticides, March 10, 2025) Following International Women’s Day, celebrated on March 8, 2025, the poignant findings on women, gender, and hazardous substances in a United Nations report raise critical issues of concern and cause for urgent action to phase out petrochemicals. The Report of the Special Rapporteur on the implications for human rights of the environmentally sound management and disposal of hazardous substances and wastes, by Marcos Orellana, was delivered to the 79th Session of the United Nations General Assembly in July 2024. Excerpts from the report follow: “Women make up roughly 60 to 70 per cent of the agricultural labour force in developing countries where pesticides and pesticide handling are especially poorly regulated. In Zambia, for example, two thirds of the labour force is engaged in agriculture, and 78 per cent are women farmers and peasants. Women there play a significant role in pesticide application, often without any or adequate personal protective equipment, especially during activities such as weeding, harvesting, and washing pesticide-laden clothes.” “In higher-income countries, women who do agricultural work are often poor and/or migrants; pesticides are one of many dimensions of marginalization and damage to their well-being. The European agriculture sector uses many seasonal and […]

Public Urged To Tell EPA That It Is Time To Stop Killing Biodiversity with the Weed Killer Atrazine

Monday, January 13th, 2025

(Beyond Pesticides, January 13, 2025) The U.S. Environmental Protection Agency (EPA) is officially taking comments on whether to issue new restrictions on the herbicide atrazine’s use. Beyond Pesticides is telling the agency that it is time to recognize the biodiversity destruction that atrazine is causing and the viability of alternative organic management practices. The group has released an action and is asking the public to join this campaign to ban atrazine. As a yardstick for what is possible under existing federal pesticide law (the Federal Insecticide, Fungicide, and Rodenticide Act), EPA on August 7, 2024 announced that it was taking emergency action to ban the weed killer Dacthal (or DCPA–dimethyl tetrachloroterephthalate), leaving many people asking, “Why Dacthal and not other very hazardous pesticides?” The weed killer atrazine (in the triazine chemical family) poses similar elevated hazards to people and the environment, has proven to be impossible to contain, and has viable alternatives. Therefore, we need to challenge EPA to apply the same standard that removed Dacthal from the market to the long list of pesticides that are contributing to a health crisis, biodiversity collapse, and the climate emergency.  In its current proposal, EPA is choosing to downplay atrazine’s risk to ecosystems, allow more contamination with […]

Glyphosate Mixtures Show Lethal and Sublethal Effects to Embryos, Highlights Regulatory Deficiencies

Wednesday, November 13th, 2024

(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 […]

Nat’l Forum Nov.14 Focuses on Petrochemical Endocrine-Disrupting Chemicals; Calls for Paraquat Ban Continue

Tuesday, November 12th, 2024

(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 […]

Deadly Endocrine Disrupting Pesticides Subject to EPA Proposals that Fall Far Short, According to Advocates

Monday, November 4th, 2024

(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 […]

Lawsuit Settlement Tackles EPA’s Dramatic Failure to Regulate Endocrine Disruptors, Despite Fed Mandate

Tuesday, October 29th, 2024

(Beyond Pesticides, October 29, 2024) STARTS TOMORROW—NATIONAL FORUM: IMPERATIVES FOR A SUSTAINABLE FUTURE. A legal victory in federal court is the latest in a series of attempts to force the U.S. Environmental Protection Agency (EPA) to fulfill the mandate given to it by Congress in 1996 to test all pesticides for their endocrine disrupting effects and regulate them accordingly. The case in the U.S. District Court for the Northern District of California was brought by the Center for Food Safety (CFS) and a collection of agricultural workers’ organizations, farmers’ groups, and pesticide activists. Beyond Pesticides wrote in 2019, EPA’s “Endocrine Disruptor Screening Program (EDSP) began, then virtually stopped, its review and regulation of endocrine disrupting pesticides, despite [its 1996 Congressional mandate] to develop a screening program within two years and then begin regulating.” (See timeline, Figure 2, p11.) After the release of a  a damning 2021 Office of Inspector General (OIG) report (see Beyond Pesticides’ reporting) on the agency’s lack of progress in protecting the population from potentially damaging endocrine disruption impacts of exposures to synthetic chemical pesticides (and other chemicals of concern), CFS wrote: “The 2021 [OIG] report included the shocking revelation that some EPA staff were instructed to function as […]

Beyond Pesticides Urges Ban of Weed Killer Paraquat Using Same Criteria Used in the Landmark Dacthal Ban

Tuesday, October 1st, 2024

(Beyond Pesticides, October 1, 2024) While the Environmental Protection Agency (EPA) received accolades for its August 7, 2024, decision to ban the herbicide Dacthal (or DCPA—dimethyl tetrachloroterephthalate), it also leaves many people asking, “Why Dacthal and not other very hazardous pesticides?” Paraquat, for example, poses similar elevated hazards to people and the environment, has no antidote, and has viable alternatives. Therefore, Beyond Pesticides is challenging EPA to apply the same standard that removed Dacthal from the market to the long list of pesticides that are contributing to a health crisis, biodiversity collapse, and the climate emergency.  In the case of Dacthal, EPA used the “imminent hazard” clause of the federal pesticide law to immediately suspend the chemical’s use. At the same time, the agency is exercising its authority to prohibit the continued use of Dacthal’s existing stocks, a power that EPA rarely uses. Additionally, the agency, in coordination with the U.S. Department of Agriculture, found that there were alternatives to Dacthal. Based on the reasoning in the Dacthal decision, EPA should ban paraquat, Beyond Pesticides says. >> EPA must apply the standard of the Dacthal decision to paraquat and issue an emergency suspension and prohibit use of existing stocks.  Paraquat […]

Human Health Disregarded with Obsolete Regulations and Risk Management, Researchers Find

Tuesday, September 24th, 2024

(Beyond Pesticides, September 24, 2024) Recent commentary in Frontiers in Toxicology by two researchers, Maricel Maffini, PhD and Laura Vandenberg, PhD, highlights the pitfalls in the current regulatory systems in the United States (U.S.) for chemicals that threaten human health. Despite many advancements in science over the past few decades, and the wealth of studies that tie chemical exposure to negative health effects, risk assessments, and subsequent risk management, remain “static” and “outdated,” according to the authors. “There is increasing concern amongst public health professionals, environmental health scientists, and medical organizations about exposures to synthetic chemicals,” the researchers say. “These organizations’ concerns are based on the overwhelming evidence showing associations between chemical exposures and adverse health outcomes in human populations.” Such concerns have sparked a debate on current regulatory methods for chemicals that are present in highly used products, such as pesticides, plastic containers, and food.    The authors continue, “There are now thousands of studies showing associations between these chemicals and adverse health effects in humans including neurological disorders and learning disabilities, metabolic outcomes, infertility, thyroid dysfunction, and cancers.” Additional health effects can be seen in the Pesticide-Induced Diseases Database. Of the many harmful chemicals, per- and polyfluoroalkyl substances […]

Beyond Pesticides Rallies Public to Ban Weed Killer Atrazine with Standard EPA Used Earlier to Ban Dacthal

Monday, August 26th, 2024

(Beyond Pesticides, August 26, 2024) In July, the U.S. Environmental Protection Agency (EPA) announced it was raising the allowable levels of the highly toxic weed killer atrazine in the nation’s waterways from the 2016 level of 3.4 to 9.7 micrograms per liter (µg/L), which scientists and environmental advocates say is a serious threat to aquatic plants, fish, invertebrates, and amphibians, in addition to people who recreate in waterways or eat food from them. With EPA’s August 7 decision to ban the weed killer Dacthal (or DCPA–dimethyl tetrachloroterephthalate), Beyond Pesticides is rallying public support for the removal of atrazine from the market under the same standards of harm, inability to mitigate hazards, and the availability of alternatives. As Beyond Pesticides points out in its 2022 atrazine comments (2020 and 2016 comments included) to EPA, the agency in November 2021 released the final Biological Evaluation (BE) assessing risks to listed species from labeled uses of atrazine (in the triazine chemical family). The agency made “likely to adversely affect (LAA) determinations” for 1,013 species and 328 critical habitats, which it is now rejecting, while using a “community-equivalent level of concern (CE-LOC)” measure that is filled with uncertainty and lacks any sense of precaution with […]

Elevating the Urgent Need To Act on Biodiversity, Drawing on the EPA’s Emergency Ban of Dacthal Weed Killer

Monday, August 12th, 2024

(Beyond Pesticides, August 12, 2024)  When the U.S. Environmental Protection Agency (EPA) issued an emergency ban of the weed killer Dacthal (DCPA) last week, it said that there are no “practicable mitigation measures” to protect against identified hazards—a clear and honest assessment of the limits of pesticide product label changes and use restrictions. Now, the question is whether the same thinking can be applied across the EPA’s pesticide program, addressing the urgent need to protect biodiversity. In the Dacthal proclamation, EPA said it consulted with the U.S. Department of Agriculture (USDA) on “alternatives to this pesticide,” and presumably determined that there were “alternative chemicals” that could be used in chemical-intensive agriculture—while not considering “alternatives to chemicals.” This is the framework that is understood to be EPA’s process that keeps pest management on a pesticide treadmill except in extremely rare cases (this being the second in nearly 40 years). It is also the framework that has led to catastrophic events or existential crises on biodiversity collapse, health threats, and the climate emergency. On biodiversity, the mix of diverse and intricate relationships of organisms in nature that are essential to the sustaining of life, EPA’s pesticide program, the Office of Pesticide Programs, has […]

Biodiversity Critical to Mosquito Management Practices that Protect Ecosytems

Monday, July 22nd, 2024

(Beyond Pesticides, July 22, 2024) Mosquito management practices, typically reliant on toxic pesticides, can be antithetical to biodiversity protection. In this respect, consideration being given to biodiversity conservation goals in the Commonwealth of Massachusetts raise important issues critical of the chemical-intensive practices that are conventionally used to control mosquitoes. The state is taking public comments until August 30, 2024 on the development of biodiversity conservation goals. In an executive order (no.618), Biodiversity Conservation, issued September 21, 2023, Governor Maura Healey (D) directed the state’s Department of Fish and Game to “conduct a comprehensive review of the existing efforts of all executive department offices and agencies to support biodiversity conservation in Massachusetts [and] recommend biodiversity conservation goals for 2030, 2040, and 2050 and strategies to meet those goals.”  [Massachusetts residents, please look out for an action from Beyond Pesticides.] In response to development of biodiversity goals in Massachusetts, last week Beyond Pesticides testified before the Massachusetts Fish and Game Department and urged the state to adopt a broad government-wide strategy that establishes biodiversity protection and enhancement as a basic tenet for all programmatic decisions going forward. In this context, Beyond Pesticides identified the following issues, among others, which stand out as […]

Study Identifies Developmental Effects from Neonicotinoid Insecticides that Harm Biodiversity

Thursday, May 16th, 2024

(Beyond Pesticides, May 16, 2024) In a recent study at the Institute of Biochemistry and Molecular Biology at Ulm University in Germany, published in Current Research in Toxicology, scientists exposed embryos of South African clawed frogs (Xenopus laevis) to three neonicotinoids (NEOs), which led to developmental effects down to a molecular level. These frogs are a well-established model species often used in ecotoxicology studies as bioindicators for overall environmental and ecosystem health. When amphibian species like Xenopus laevis are exposed to contaminants in the water, it leads to negative impacts in the food chain and harms biodiversity. The study concludes that exposure to NEOs directly or through contaminated water leaves entire ecosystems vulnerable.    The NEOs that the embryos were subjected to include imidacloprid (IMD), thiamethoxam (TMX), and its metabolite clothianidin (CLO). NEOs are a class of insecticides that target the central nervous system of insects and lead to death. These insecticides pose a potential hazard to nontarget organisms, such as animals and humans, since they are persistent in the environment and “are found in natural waters as well as in tap water and human urine in regions where NEOs are widely used,” this study states.

EPA Draft Herbicide Strategy Update Further Weakens Plan to Protect Endangered Species

Wednesday, April 24th, 2024

(Beyond Pesticides, April 24, 2024) On April 16, 2024, the U.S. Environmental Protection Agency (EPA) posted an “update” to the Draft Herbicide Strategy Framework (Draft Herbicide Strategy Framework to Reduce Exposure of Federally Listed Endangered and Threatened Species and Designated Critical Habitats from the Use of Conventional Agricultural Herbicides) that was released last summer, weakening aspects of the agency’s efforts to “protect” endangered species from herbicide use. The update outlines three types of modifications to the Draft Strategy, including “simplifying” its approach, increasing growers’ “flexibility” when applying mitigation measures, and reducing the mitigation measures required in certain situations. By reducing the stringency of the Strategy, advocates are again questioning EPA’s commitment to fulfilling legal requirements under the Endangered Species Act (ESA) or protecting endangered species and their habitats in the midst of an unprecedented rate of global extinction. ESA is celebrated as one of the most far-reaching conservation laws globally, credited with preventing the extinction of 99 percent of those species the government targets for protection, according to the U.S. Fish and Wildlife Service (USFWS). ESA establishes a framework to categorize species as “endangered” or “threatened,” granting them specific protections. Under ESA, EPA is required to consult with relevant agencies […]

Pesticide Exposure Linked to Obesity, Type 2 Diabetes, and Metabolic Disease in Seniors

Tuesday, February 27th, 2024

(Beyond Pesticides, February 27, 2024) Popular culture and official policy continue to ignore a blatant source of the rise in obesity: chemical exposures, including pesticides. A study, “Associations of chronic exposure to a mixture of pesticides and type 2 diabetes mellitus in a Chinese elderly population,” contributes to the now-massive trove of evidence linking pesticides to diseases and shows that by the time people reach retirement age they are suffering from a heavy burden of contamination that raises their risk of complex disease. Since the 1960s, obesity in both adults and children has nearly tripled. More than half of U.S. adults were either obese or severely obese by 2018, according to data from the National Health and Nutrition Examination Study. The 55-year trend line is decidedly upward. More women than men are obese, and black women suffer the most, but men are racing to catch up. Between 1999 and 2018, Mexican American men shot up from the lowest percentage of obesity to nearly the highest. Obesity is a milestone on the road to Type 2 diabetes, heart disease, high blood pressure, kidney failure, joint replacement, and more. The causes of obesity are severely misunderstood. Most people believe that discipline and […]
