(Beyond Pesticides, August 26, 2019) U.S. Senator Cory Booker (D-NJ) recently released draft legislation that will – among other initiatives – promote carbon-sequestering practices in agriculture. The draft Climate Stewardship Act includes farmers as a critical component in the response to the climate crisis by encouraging “carbon farming” through incentives, training, and research. U.S. Representative Deb Haaland (D-NM) is championing companion legislation in the U.S. House of Representatives. The bill will likely be introduced in September when Congress reconvenes. Ask your U.S. Representative and Senators to Co-sponsor the Climate Stewardship Act and Help Farmers Save the Planet. July of 2019 was the hottest month ever recorded on Earth. The last time atmospheric carbon dioxide levels were this high (over 415 ppm) was during the Pliocene period – between 5.3 and 2.6 million years ago. The best time to have addressed global warming was 20 years ago, but the second-best time is now. Organic, regenerative agricultural practices help mend the earth from the ground up. In addition to incentivizing soil health practices that organic farmers already employ, the bill adds $75,000,000 to the organic research and extension initiative (OREI). The bill contains a requirement that no less than 50% of these funds apply to reducing […]

(Beyond Pesticides, August 22, 2019) In early August, experts from European Union (EU) member states and staff members of the European Food Safety Authority (EFSA) announced their conclusion that chlorpyrifos fails to meet criteria for renewed approval for use, potentially moving the EU a step closer to an outright ban. This ends the green light that chlorpyrifos (and its structurally close cousin, chlorpyrifos-methyl) have enjoyed at the EU level since 2006. That permitting is set to expire in January of 2020, although eight member states — Germany, Ireland, Finland, Denmark, Sweden, Latvia, Lithuania, and Slovenia — had already either banned or never authorized chlorpyrifos use in their countries. In the U.S., states are picking up the slack on efforts against chlorpyrifos use as, in the tenure of the current administration, the Environmental Protection Agency (EPA) has chosen to protect industry rather than human health and the environment. The step EFSA took was unusual in that the agency does not typically publish findings before ongoing peer reviews are completed. EUObserver.com reports that EFSA’s public statement was triggered by a July 2019 EU request for information “on the available outcomes of the human health assessment in the context of the pesticides peer […]

(Beyond Pesticides, August 21, 2019) A birth cohort study in Canada found elevated levels of fluoride exposure during pregnancy are associated with lower IQ scores in 3 to 4-year-old children. This new research, published in the journal JAMA Pediatrics, builds on previous analyses that suggest high fluoride exposure is related to adverse effects to children’s neurodevelopment. Researchers recommend that pregnant mothers should reduce fluoride intake during pregnancy. Noting the controversy of the study, JAMA Pediatrics editor Dr. Dimitri Christakis said it was subjected to “additional scrutiny for its methods and the presentation of its findings.” The Maternal-Infant Research on Environmental Chemicals (MIREC) program recruited pregnant mothers to participate in the study from 2008-2011. A total of 601 mother-child pairs from 6 major cities participated; 41% of them lived in cities with fluoridated municipal water. Exposure was measured through urine samples as well as self-reported maternal daily intake. Children were between ages 3 and 4 when tested for IQ. A 1mg/L increase in maternal urinary fluoride is associated with a 3.7-point decrease in IQ. These findings echo a previous study in Mexico that found a 6-point lower IQ score in school-age children associated with a 1mg/L in maternal urinary fluoride. Women who […]

(Beyond Pesticides, August 15, 2019) An article in the journal Plos One, “An assessment of acute insecticide toxicity loading (AITL) of chemical pesticides used on agricultural land in the United States,” shows that recent shifts in insecticide use—from organophosphates and carbamates to synthetic pyrethroids and neonicotinoids—have made a large contribution to the ongoing insect apocalypse. This shift to insecticides that target insects based on both selective toxicity and delivery method occurs within a context of shrinking habitat and biodiversity. The study, by Michael DiBartolomeis, PhD, Susan Kegley, PhD, Pierre Mineau, PhD, Rosemarie Radford, and Kendra Klein, PhD, presents a measure of acute insecticide toxicity loading that incorporates acute toxicity, quantity used, and the rate at which the insecticide degrades. Goulson et al. applied a similar measure in Great Britain that did not incorporate the rate of degradation. Both studies use the median lethal dose (LD50) to honey bees as a measure of acute toxicity and calculate the potential number of bee deaths based on the number of lethal doses of various insecticides applied in the field. In both cases, researchers used toxicity estimates for honey bees because they are widely available. Other insects may be more or less sensitive. The […]

(Beyond Pesticides, August 13, 2019) The U.S. Environmental Protection Agency (EPA) is refusing to approve product labels that disclose that the herbicide glyphosate may cause cancer, according to a press release published last week. The move comes after the state of California listed glyphosate on its Prop 65 list of chemicals known to cause cancer, birth defects or other reproductive harm. Health advocates are condemning the decision as the latest in a long string of EPA actions aimed at benefiting industry at the expense of consumer and public health. Many are concerned that the incessant stream of industry-friendly decisions is eroding public trust in the agency and its ability to act as an independent regulator. While a state judge gave the Prop 65 warning labels the go-ahead, a prior ruling from U.S. District Court Judge William Shubb in Sacramento placed a preliminary injunction on the California requirement that remains in place today. The state added glyphosate to its Prop 65 list after the International Agency for Research on Cancer (IARC) designated the chemical as a group 2A carcinogen.  Under Prop 65, California regulators are required to provide “clear and reasonable” warning labels when any one of four requirements in the […]

(Beyond Pesticides, August 12, 2019) Once again, the Environmental Protection Agency (EPA) has rejected the evidence provided by independent scientists and sided with the pesticide industry promoting its products; this time, removing a safety for factor for children on some of the most widely used insecticides, synthetic pyrethroids. When EPA cannot do its job, it is time for Congress to step in. Tell Congress: To Protect Children, EPA Must Consider the Independent Peer-Reviewed Science, Not Bend to Industry Lobbying. In a move that challenges the preponderance of independent peer-reviewed scientific findings on children’s health, EPA recently stripped away protections that limit children’s exposure to class of chemicals associated with childhood cancer, autism other learning disorders, and asthma. The result of the agency’s actions will be a dramatic increase in the use of synthetic pyrethroids, insecticides found in indoor and outdoor bug sprays, bug bombs, and often used on conventionally grown fruits and vegetables. EPA, under the leadership of former fossil fuel lobbyist Andrew Wheeler, is embracing the positions of the pesticide industry while ignoring independent science and health and environmental groups. In 2017, the agrichemical industry trade group, Croplife America, submitted comments to EPA during its review of synthetic pyrethroids. The organization urged EPA to rely on a […]

(Beyond Pesticides, August 5, 2019) The U.S. Department of Agriculture (USDA) appears to have forgotten the lesson learned 20 years ago when it was forced to ban genetic engineering (GE) in organic regulations. At a July 17 hearing called by the U.S. House Agriculture Subcommittee on Biotechnology, Horticulture, and Research on “Assessing the Effectiveness of the National Organic Program,” Greg Ibach, the USDA’s Under Secretary for Marketing and Regulatory Programs, stated, “There is the opportunity to open the discussion to consider whether it is appropriate for some of these new technologies, including gene editing, to be eligible to be used to enhance organic production.” In 1997, the U.S. Department of Agriculture (USDA) published a draft rule that would have allowed GE, irradiation, and sewage sludge (the “Big Three”) in organic production, which was met by the second largest number of comments the agency had ever received—well before the days of internet advocacy—overwhelmingly opposing the inclusion of the “Big Three.”  The prohibition of gene editing falls under the “excluded methods” provision of the organic regulations. The law prohibits “a variety of methods used to genetically modify organisms or influence their growth and development by means that are not possible under natural conditions […]

(Beyond Pesticides, August 1, 2019) Last month, the Brazilian Ministry of Agriculture approved the registration of 51 additional hazardous pesticides and brought the total to 262 newly approved pesticides this year. Moreover, Brazil’s health surveillance agency, Anvisa, approved new rules that establish risk of death as the singular criteria for determining toxicity of pesticides. Human Rights Watch, a nonprofit that conducts local investigations, reports that the government has simultaneously been unresponsive to incidents of pesticide poisoning. Brazil’s president, Jair Bolsonoro, is known for his far-right politics, and has been accused of corruption, scandals, and disregard for the environment. This rapid registration of novel pesticides is unprecedented in Brazil. Many of the products are generic versions of existing formulas, with government officials seeking to lower the price of pesticides. Products include insecticides with the active ingredient sulfoxaflor, a bee-toxic pesticide that has also recently gained traction in the U.S. despite pushback from beekeepers and environmentalists. While an American license for a pesticide, for example, lasts 15 years, Brazilian registration of pesticides never expires. Generic products lower the price barrier to amplified use of these interminable, toxic pesticides. In 1989, Brazil established one of the toughest pesticide laws in the world that […]

(Beyond Pesticides, July 30, 2019) Earlier this month, the U.S. Environmental Protection Agency announced a decision to register new uses for the bee-toxic pesticide sulfoxaflor. The decision closely followed a USDA announcement halting the Honey Bee Colonies Survey, combining blows to already suffering beekeepers. According to the nonprofit Bee Informed, this past winter tallied the most colonies lost in a decade—an estimated 37% between October 1, 2018 and April 1, 2019. “Proposing to register sulfoxaflor for use on bee-attractive crops, in the midst of an ongoing pollinator crisis, is the height of irresponsibility,” said Drew Toher, community resource and policy director for Beyond Pesticides in an interview for Bloomberg Environment. “When all of the available data points to significant risks to pollinators from use of this chemical we must face the facts: EPA is working towards the protection of pesticide industry, not the environment,” he said. Sulfoxaflor is a systemic insecticide whose mode of action is the same as neonicotinoid pesticides. After application, the chemical is absorbed and distributed throughout the plant, including pollen and nectar. These insecticides are selective agonists of insects’ nicotinic acetylcholine receptors—they bind to the receptor and cause it to activate. The impact on foraging bees […]

(Beyond Pesticides, July 29, 2019) A research study, published in March in Scientific Reports, uncovers a pesticide effect on a sugar-metabolizing enzyme common to all cells that has broad health ramifications ignored by the U.S. Environmental Protection Agency’s (EPA) safety testing protocol. This finding raises a larger question regarding the need for EPA to test for the synergistic effects of pesticides, whereby pesticides and chemicals in combination have an even greater effect than they do by themselves. The research, by T. Tristan Brandhorst, PhD, Iain Kean, PhD, and others in the lab of Bruce Klein, PhD, of the University of Wisconsin–Madison and UW School ofMedicine and Public Health, specifically sheds light on the mode of action of the fungicide fludioxonil. Fludioxonil, a phenylpyrrole fungicide, was developed to treat seeds during storage, and has come to be used commonly on grains, vegetables, fruits, and ornamental plants during cultivation, and produce after harvest to extend “shelf life.” As reported by the American Association for the Advancement of Science publication, EurekAlert, “The ability of [the fungicide] fludioxonil to act on a sugar-metabolizing enzyme common to all cells, and to produce the damaging compound methylglyoxal, may mean that the pesticide has more potential to harm non-fungal cells than previously […]

(Beyond Pesticides, July 25, 2019) Professors are experiencing damage to their soybean field research as a result of dicamba drift from neighboring agricultural fields. Experts worry that continued drift will make it impossible to carry out public research integral to non-genetically engineered soybean production. These reports, recent studies of dicamba drift potential, and numerous lawsuits counter Monsanto/Bayer’s claims that dicamba poses no drift threat when used properly. Monsanto, now owned by Bayer, manufactures both dicamba and genetically engineered, herbicide-tolerant crops. Dicamba mimics natural plant hormones, auxins, to cause uncontrolled and abnormal growth in non-tolerant plants; soybeans are especially vulnerable. Pengyn Chen, PhD, a professor of soybean breeding and genetics at the University of Missouri’s Fisher Delta Research Center, reports that his soybeans leaves curled up into cups and grew fragile unusual side branches due to dicamba drift. Dr. Chen has seen damage for the past three years as dicamba use has increased around his research station. The nature of Dr. Chen’s work bars him from switching to dicamba resistant crops, a switch many farmers make to avoid the impacts of drift. Dr. Chen studies many varieties of soybeans, including obscure types that private companies ignore. His research aims to find […]

(Beyond Pesticides, July 24, 2019) The U.S. District Court for the District of Hawai’i has found the state’s Agribusiness Development Corporation (ADC) guilty of violating the Clean Water Act. The case, brought by organizations including Surfrider Foundation, Pesticide Action Network North America, and others, represented by Earthjustice, accused ADC of dumping water contaminated with pesticides, including the cancer-causing herbicide glyphosate, into the Pacific Ocean off of West Kauai without a permit since 2015. Hawai’i bears the brunt of agribusiness wrongdoings, and Kauai in particular has faced past issues of pesticide injustice at the hands of the ADC. However, this new ruling marks a turn in past decisions that have favored agribusiness, as the judge found ADC violations. Advocates hope that this decision will highlight the need for government accountability, and increase transparency about what pesticides and chemicals are entering our oceans. The ADC system collects groundwater and storm water runoff through a series of canals, ditches, and pumps. The polluted water, full of toxic pesticides and chemicals, discharges into the Pacific Ocean along popular beaches that residents use for recreational activities, including surfing and fishing. The case brought against ADC accuses the department of dumping this water without a National […]

(Beyond Pesticides, July 23, 2019) Last week, U.S. Representative Nydia M. Velazquez introduced legislation to cancel all uses of the pesticide paraquat, which is acutely toxic and strongly linked to Parkinson’s disease. The move is supported by the Unified Parkinson’s Advocacy Council – a group led by The Michael J. Fox Foundation for Parkinson’s Research – as well as other health and environmental groups such as Beyond Pesticides. Paraquat, which is a dangerous, fast-acting nonselective herbicide that kills by burning living tissues, is also unnecessary. Organic agriculture provides an alternative that does not depend on toxic chemicals like paraquat. Tell your U.S. Representative to support H.R. 3817 to cancel the use of paraquat. According to the EPA, “one small sip [of paraquat] can be fatal, and there is no antidote.” Advocates are pushing for its elimination from the American agriculture system for many reasons, including acute toxicity and organ failure by inhalation, oral intake and dermal absorption; chronic toxicity affecting the eyes, lungs, liver, kidneys and endocrine system; and a higher incidence of various cancers after exposure. The EPA characterizes paraquat as “extremely biologically active and toxic to plants and animals.” The agency has previously determined that exposure to this herbicide […]

(Beyond Pesticides, July 22, 2019) The U.S. Environmental Protection Agency (EPA) will permit the continued use of a known neurotoxic insecticide on the food the Americans eat, the agency announced yesterday in response to a lawsuit filed by public health groups. Health advocates say the move to continue chlorpyrifos use is the latest example of the agency working to protect the profits of industry over the health of Americans. “By allowing chlorpyrifos to stay in our fruits and vegetables, Trump’s EPA is breaking the law and neglecting the overwhelming scientific evidence that this pesticide harms children’s brains,” said Patti Goldman, an attorney for Earthjustice. “It is a tragedy that this administration sides with corporations instead of children’s health.” Under a lawsuit filed in the 9th Circuit US Court of Appeals, EPA had 90 days to provide a justification for why the pesticide should remain on the market. EPA denied the petition yesterday, and rather than providing positive justification for continued use of the chemical, attacked the sound science claimants urged the agency to consider as “not…valid, complete, and reliable.” In the absence of EPA action, several states are leading in the protection of their residents by rejecting the agency’s determination regarding […]

(Beyond Pesticides, July 18, 2019) Pesticide products containing the weed killer dicamba become more volatile and drift-prone in hot conditions and when tank-mixed with glyphosate, according to a recent study conducted by scientists at the University of Tennessee. The findings help explain rampant complaints from farmers in the South and Midwest experiencing crop loss and economic hardship as a result of drift from new dicamba products, which are formulated with glyphosate for use on genetically engineered (GE) cotton and soy. While states have taken the lead in regulating the use of GE dicamba products, top political officials within Administrator Andrew Wheeler’s EPA overruled the findings from agency scientists urging larger buffer zones to protect neighboring crops and farm fields. During a 60-hour window, scientists applied various GE dicamba products (Clarity and XtendiMax) over a range of temperatures and took air samples. As temperatures increased, so did the volatilization and drift of dicamba, even in formulations touted as “low volatility.” Adding glyphosate to the mixture produced stark results, increasing concentrations of dicamba in the air up to nine times compared to dicamba alone. Tom Mueller, PhD, a professor in the UT Department of Plant Sciences, stated in a press release that […]

(Beyond Pesticides, July 17, 2019) A March 2017 bird kill incident in Modesto, CA can be traced directly back to an insecticide “soil drench” applied to the base of several elm trees by pesticide applicators hired by the city, as detailed in a study published last month in the Journal of Environmental Toxicology and Chemistry. The chemical in question, the neonicotinoid imidacloprid, is implicated in the ongoing pollinator crisis and insect apocalypse, but can also affect bird populations. Prior research estimated that a single seed coated with the insecticide is enough to kill a songbird; this study confirms that such a scenario can and does play out in the real world. Progress and improvement will only occur when pest management practices stop focusing on pesticide use to solve routine pest problems and emphasize prevention. As part of city-wide pest management activities, Modesto officials said that imidacloprid was applied to elm trees in several front yards in a local neighborhood. The application took the form of a “soil drench,” which is when pesticide products are applied to the soil around the base of a tree or shrub. The systemic property of imidacloprid and other systemic insecticides means that the chemical will […]

(Beyond Pesticides, July 12, 2019) The U.S. Department of Agriculture (USDA) announced, on Saturday, July 6 that it would suspend indefinitely the data collection for its Honey Bee Colonies survey and report. The move came, tellingly, less than three weeks after the Environmental Protection Agency (EPA) once again approved “emergency” uses of the pesticide sulfoxaflor, a bee-killing compound similar to the notorious neonicotinoids, insecticides that contribute significantly to the phenomena of pollinator collapse (“colony collapse disorder”) and massive insect loss (“insect apocalypse”) that are underway worldwide. Sulfoxaflor is one of the many toxic pesticides that threaten honey bees, which are critical pollinators responsible for one-third of the food we humans consume. Permitting its use and then ceasing to collect and report data on the status of honey bees that are likely to be impacted is not only a recipe for kneecapping the study of bee decline and imperiling the food supply, but also, another example of the corruption for which this administration is infamous. As The Huffington Post reported, “Critics say the USDA’s move is the latest evidence of the Trump administration’s war on science, and its goal of suppressing information about serious environmental harms increasing under Donald Trump’s presidency.” Union […]

(Beyond Pesticides, July 11, 2019) Pregnant mothers with higher concentrations of pesticide metabolites (breakdown products) in their urine are more likely to have children who develop symptoms of Attention Deficit/Hyperactivity Disorder (ADHD), according to research conducted by the University of Southern Denmark and Odense University Hospital. The results of this study are consistent with past findings from Rutgers University and Cincinnati Children’s Medical Center, indicating a need for researchers to determine causality, and pesticide regulators to rein in toxic insecticide use. The pesticides investigated by researchers were breakdown products of the organophosphate chlorpyrifos, and the synthetic pyrethroid class of insecticides. The residue of these chemicals are frequently detected on conventional, industrially farmed food products. Although chlorpyrifos is banned from residential use in the U.S., most household bug sprays such as RAID contain high amounts of synthetic pyrethroids. Among the 948 pregnant Danish women tested, 90% had some level of chlorpyrifos metabolites (3,5,6-trichloro-2-pyridinol) detected in their urine, and 94% were positive for the generic pyrethroid metabolite (3-phenoxybenzoic acid). Scientists continued to follow up with pregnant women’s children through the first five years of life. A child behavioral check list was completed to determine the relative level of ADHD symptoms. Concentrations of […]

(Beyond Pesticides, July 10, 2019) The California Coastal Commission will host a public hearing today on a U.S. Fish and Wildlife Service (USFWS) proposal to drop 1.5 tons of the rodenticide brodifacoum, an extremely potent anticoagulant, on the Farallon Islands National Wildlife Refuge. The Los Angeles Times headline on July 7 read, “Biologists say it’s for the best.” At the least, it is important to highlight that all biologists have not come to a consensus and the topic is very much still under debate. The commission has already received over 700 emails regarding the drop, with 600 opposing it. Home to rare, endemic seabirds such as the ashy storm-petrel, the Farallon Islands certainly have a serious mouse problem – 59,000 rodents occupy the rocky islands. Mice compete with native species for resources and attract an average of six burrowing owls a year. Owls feast upon ashy storm-petrels when mouse populations drop during the winter, killing hundreds of petrels annually. The global population of the ashy storm-petrel is small (10,000 – 20,000), but it is not considered an endangered species. The Audubon Society in California, which supports the brodifacoum program, worked with experts who say the eradication of invasive mice is […]

(Beyond Pesticides, June 8, 2019) Scientists studying the precipitous decline in populations of monarch butterflies are searching for causes, and pesticide use is one of the factors under their (figurative) microscopes. Purdue University entomology professor Ian Kaplan, PhD and doctoral student Paola Olaya-Arenas recently turned their attention to a poorly studied potential factor — exposure during monarchs’ larval stage to non-target pesticides on their primary host plant and food source, common milkweed (Asclepias syriaca). In Frontiers in Ecology and Evolution, the researchers report finding evidence of 14 different agricultural pesticides on milkweed near Indiana farm fields, including neonicotinoids clothianidin and thiamethoxam, the pyrethroid deltamethrin, and imidacloprid in a few samples. The research team’s primary aim was to identify and measure the range of pesticides to which monarch caterpillars might be exposed, or which they might consume, on milkweed plants in agricultural landscapes. Secondarily, they hoped to learn how pesticide presence varies with distance between milkweed plants and nearby agricultural sites. In the subject Indiana environs, where corn and soybeans are dominant crops, the study found neonicotinoid residues on milkweed, particularly those of the active ingredients in clothianidin and thiamethoxam. They note, “Although seed treatment data are no longer reported for U.S. […]

(Beyond Pesticides, July 5, 2019) This is a story about a chemical pesticide, a fungicide, in wide use for which the mode of action, i.e., the ability to cause harm, has not been fully understood. It is not a story unique to this pesticide. Rather, it is an important story to consider when deciding to use a pesticide or allowing a pesticide to be used. The question is whether the chemical could be broadly problematic beyond the target organisms, in this case fungi? In its coverage of a study published in March, the American Association for the Advancement of Science publication, EurekAlert, reported that, “The ability of [the fungicide] fludioxonil to act on a sugar-metabolizing enzyme common to all cells, and to produce the damaging compound methylglyoxal, may mean that the pesticide has more potential to harm non-fungal cells than previously thought. Although fludioxonil has been deemed safe for use, the authors . . . suggest that the effects of this widely used pesticide has upon animals be re-examined.” The research study, published in March in Scientific Reports and led by T. Tristan Brandhorst, PhD (in the lab of Dr. Bruce Klein at the University of Wisconsin–Madison and UW School of […]

(Beyond Pesticides, July 3, 2019) A disturbing association between urinary triclosan concentrations and osteoporosis has been identified in an epidemiological study. Drawing from the National Health and Nutrition Examination Survey (NHANES) results for 1,848 U.S. adult women, the authors conclude that higher concentrations of urinary triclosan are associated with lower bone mass density and higher prevalence of osteoporosis among U.S. adult women. The study, published in the Journal of Clinical Endocrinology and Metabolism, adds weight to previous laboratory results, which showed that endocrine-disrupting chemicals such as triclosan can interfere with bone metabolism. Triclosan and its byproducts are known endocrine disruptors and have been shown in laboratory studies to interfere with collagen and bone structure. Taken together with previous findings, the new epidemiological results demonstrate that the ubiquitous endocrine disruptor triclosan “could lead to lower BMD [benchmark dose] and increased prevalence of osteoporosis in U.S. adult women.” Triclosan is used as an antimicrobial agent in products regulated by both the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA), and cumulative exposure to triclosan registered by both agencies pose unacceptable risks to human health and the environment. Triclosan exposure has become so common that it has shown up in […]

(Beyond Pesticides, July 1, 2019) France made a decision in May to ban a widely-used fungicide because it damages the endocrine system. In contrast, there has been a stark failure to protect health in the U.S. Despite a Congressional mandate, EPA is not acting on endocrine disruptors linked to infertility and other reproductive disorders, diabetes, cardiovascular disease, obesity, and early puberty, as well as attention deficit hyperactivity disorder (ADHD), Parkinson’s, Alzheimer’s, and childhood and adult cancers. This is a tragedy. Ask your elected members of Congress to demand that EPA tests and acts on regulatory endocrine disruptors as required by law. In 1998, following a mandate in the Food Quality Protection Act (FQPA) of 1996, EPA established a program to screen and test pesticides and other widespread chemical substances for endocrine disrupting effects. Despite operating for 21 years, the Endocrine Disruptor Screening Program (EDSP) has made little progress in reviewing and regulating endocrine-disrupting pesticides.  As of 2019, the program has stalled entirely. To ensure appropriate follow-through, Congress gave EPA a timeline to: develop a peer-reviewed screening and testing plan with public input not later than two years after enactment (August 1998); implement screening and testing not later than three years after […]
