(Beyond Pesticides, January 17, 2018) The organophosphate insecticides chlorpyrifos, malathion, and diazinon are likely to jeopardize the continued existence of endangered species and adversely modify their critical habitats, according to the newly released report from the National Marine Fisheries Service (NMFS). The insecticide cholorpyrifos, whose ban was rescinded by the Trump Administration last year, despite overwhelming evidence of neurological and brain damage to children, is once again being shown to be too toxic for continued use. Under Section 7 of the Endangered Species Act (ESA), any agency action requires a finding that it “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” The December 31, 2017 Biological Opinion from NMFS followed an ecological assessment that relied upon multiple lines of evidence to determine effects to species and their designated habitats. These include “the direct and indirect toxicity of each chemical to aquatic taxa groups (e.g. fish, mammals, invertebrates); specific chemical characteristics of each pesticide (e.g. degradation rates, bioaccumulation rates, sorption affinities, etc.); expected environmental concentrations calculated for generic aquatic habitats; authorized pesticide product labels; maps showing the spatial overlap of listed species’ habitats with pesticide use areas; […]

(Beyond Pesticides, January 8, 2018) With a long-documented history of children’s exposure to pesticides that drift from agricultural fields to school yards, California’s new regulations establishing no-spray buffers took effort January 1, as labor and public health groups acknowledged the progress and inadequacy of the measure. The new rule, DPR 16-004 Pesticide Use Near Schoolsites, adopted by the California Department of Pesticide Regulation (DPR), prohibits many pesticide applications within a quarter mile of public K-12 schools and licensed child day-care facilities during school hours, Monday through Friday between 6 a.m. and 6 p.m. This includes all applications by aircraft, sprinklers, air-blast sprayers, and all fumigant applications. In addition, most dust and powder pesticide applications, such as sulfur, will also be prohibited during this time. The new rule was announced in November, 2017. Advocates say the new rules fail to address persistent low-level exposures associated with the use of the pesticides near schools, which are in agricultural areas that are disproportionately Latino and from farmworker families. There is continuing concern about children’s exposure to hazardous pesticides because children use school grounds after school hours and on weekends and residues from drift may remain on school grounds. Many pesticides used are persistent and systemic, lingering […]

(Beyond Pesticides, September 18, 2017) Ask California to ban the neurotoxic pesticide chlorpyrifos that’s on the food we eat from California –since the administrator of EPA refused to take the action agency scientists said is necessary to protect children. Tell California to ban chlorpyrifos! In view of EPA’s retraction of its proposal to revoke food residue tolerances of the highly neurotoxic insecticide chlorpyrifos, despite its own assessment that the chemical is too toxic to children, it is especially important that California take action to ban the chemical. California, the home of the largest agriculture industry in the country, used over 1 million pounds of chlorpyrifos on over a million acres in 2012. EPA’s assessment is also support for the classification of chlorpyrifos as a developmental toxicant, an issue being considered on a parallel track by California’s Office of Environmental Health Hazard Assessment (OEHHA), which oversees the “Prop 65” list. EPA’s assessment, which incorporates recommendations from a 2016 Scientific Advisory Panel (SAP), finds that children exposed to high levels of chlorpyrifos have mental development delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorders. The SAP agreed with EPA that there is an association between chlorpyrifos prenatal exposure and neurodevelopmental outcomes in children. […]

(Beyond Pesticides, August 29, 2017) Air monitoring in Kern County, California, finds levels of the highly neurotoxic pesticide, chlorpyrifos, in excess of the levels of concern established by the U.S. Environmental Protection Agency (EPA) for pregnant women. Chlorpyrifos is linked to low IQs, autism and other developmental neurological effects. Earlier this year, EPA Administrator Scott Pruitt refused to ban chlorpyrifos to the dismay of many scientists, medical professionals, and farmworker organizations. The California Department of Pesticide Regulation (CDPR) released its 2016 air monitoring data where it was revealed that chlorpyrifos air concentrations for a one-month period at the air monitoring site on the campus of Shafter High School in Kern County was 39.4 nanograms per cubic meter (ng/m3) – more than 18 times higher than EPA’s level of concern for pregnant women (2.1 ng/m3).  Shafter High School is some distance from fields in an area where chlorpyrifos use is not as high as in other parts of Kern County or elsewhere in California. More than 1.1 million pounds of chlorpyrifos was used in California in 2015, and more than a quarter of that is used in Kern County. High chlorpyrifos levels at a school means that children and unsuspecting teachers and […]

(Beyond Pesticides, July 27, 2017) Earlier this week U.S. Senators Tom Udall (D-NM) and Richard Blumenthal (D-CT) introduced a bill that would ban use of the insecticide chlorpyrifos. The Protect Children, Farmers and Farmworkers from Nerve Agent Pesticides Act, S. 1624, comes one week after an appeals court refused to require the U.S. Environmental Protection Agency (EPA) to make a decision over whether to ban the chemical. Removing this neurotoxic insecticide from the environment would significantly reduce health risks for children and farmworkers in underserved rural communities, build pressure to address all toxic organophosphates, and help push U.S. agriculture in a more sustainable direction. As with other organophosphate class chemicals, chlorpyrifos, first registered in 1965 by Dow Chemical, is derived from nerve agents used during World War 2. The chemical is linked to a range of negative health and environmental outcomes that warrant its prohibition. Children are at particular risk from the chemical due to their developing immune, organ, and nervous systems. As with other organophosphate nerve agents, the chemical acts on the body’s nervous system, inhibiting the movement of neurotransmitters called cholinesterase. Chlorpyrifos chemically binds to the site where cholinesterase would in the body, preventing normal nerve impulse transmission. […]

(Beyond Pesticides, June 30, 2017) Scott Pruitt, Administrator of the U.S. Environmental Protection Agency (EPA), met privately with Dow Chemical’s CEO several weeks before reversing EPA’s tentative decision to ban chlorpyrifos, according to records recently obtained by the Associated Press (AP). A copy of Mr. Pruitt’s schedule reveals he met with Dow CEO, Andrew Liveris, on March 9 at a Houston hotel and “twenty days later Pruitt announced his decision to deny a petition to ban Dow’s chlorpyrifos pesticide from being sprayed on food.” At a hearing this week, U.S. Senator Tom Udall (D-NM) pressed Mr. Pruitt to name a peer-reviewed study that indicates that chlorpyrifos is safe. Mr. Pruitt answered by saying that “he had relied on â€interagency dialogue’ with USDA [U.S. Department of Agriculture] before denying the petition to ban the chemical.” In a congressional hearing earlier this month regarding chlorpyrifos’ safety, Mr. Pruitt stated that his decision was founded on “meaningful data and meaningful science.” However, AP followed up with EPA to provide details on this science, and Mr. Pruitt’s office replied with quotes from trade groups and USDA, but failed to provide any scientific studies on the chemical’s safety. In March 2017, in an about-face, EPA’s Administrator […]

(Beyond Pesticides, June 13, 2017) Prenatal exposure to commonly used mosquito and agricultural insecticides is associated with decreased motor function in infants, according to a study published in Environment International by a team of Chinese and U.S. researchers. The results of the study should give pause to insecticide-heavy efforts to control mosquitoes as the season ramps up this summer and fall. Frequent spraying as part of efforts to control Zika in Southern Florida last year resulted in large protests and calls for a preventive management approach not dependent on toxic chemicals. For the current study, over 350 pregnant Chinese mothers were tested for the presence of organophosphate pesticides in their umbilical cord blood. Researchers looked at exposure to the insecticides naled, methamidophos, trichlorfon, chlorpyrifos, and phorate. After giving birth, their children’s motor function was tested at both six and nine months of age. Tests included an analysis of the infant’s reflexes, locomotion, grasping, stationary and visual-motor integration abilities. Scores were categorized based on gross, fine, and total motor skills, and standardized quotients were created for each of the categories. Of the over 300 mothers, roughly 240 had detectable levels of one of the insecticides in their samples. Although no differences […]

(Beyond Pesticides, June 8, 2017) On Monday, numerous organizations filed an administrative appeal to the U.S. Environmental Protection Agency (EPA), seeking to reverse Scott Pruitt’s order to continue allowing the toxic organophosphate insecticide chlorpyrifos in agriculture, and revoke all tolerances (allowed food residues) of the chemical. On the same day, Attorneys General (AGs) from seven states announced legal objections to Scott Pruitt’s order, also calling for a reversal of the decision and a revocation of all tolerances. Allowing the continued use of chlorpyrifos runs counter to findings of independent science and EPA’s own scientists, which establish unacceptable risks to humans and the environment. The administrative appeal, filed by Earthjustice on behalf of 12 environmental, labor, and civil rights organizations, resulted from the decision by EPA to allow the use of chlorpyrifos while it studies the safety of the chemical. The seven AGs, in their filing, are charging that EPA wrongfully approved the continued use of chlorpyrifos in agriculture without first gathering and assessing the full safety data, as required by the U.S. Food, Drug, and Cosmetic Act. Many environmental groups spoke out in favor of these filings. “There’s a good reason this dangerous toxin has been banned from indoor use for more […]

(Beyond Pesticides, May 12, 2017) Researchers from the University of California San Diego, School of Medicine, in collaboration with scientists from Ecuador and Minnesota, have found that exposure to heavy pesticide use during peak periods can impact neurobehavioral performance in children. The study focused on exposure to organophosphate pesticides, which have been associated with a broad range of diseases in both children and adults. The study, published in NeuroToxicology, involved 308 non-worker Ecuadorian children between the ages of 4 and 9. Neurobehavioral performance for each child was tested once between 63 and 100 days after the Mother’s Day flower harvest, which is a period of high pesticide use in Ecuador. The researchers found that children examined sooner after Mother’s Day had lower scores than children who were tested later. “Children examined sooner after the flower harvest displayed lower performance on most measures, such as attention, self-control, visuospatial processing (the ability to perceive and interact with our visual world) and sensorimotor (eye-hand coordination) compared to children examined later in a time of lower flower production and pesticide use,” said Jose R. Suarez-Lopez, MD, PhD, and lead author of the study, to ScienceBlog. Dr. Suarez-Lopez continued, “This discovery is novel because it […]

(Beyond Pesticides, April 24, 2017) After contributing $1 million to Donald Trump’s presidential festivities, pesticide maker Dow Chemical Co. is asking the Administration to set aside previous findings of federal scientists across multiple agencies that confirm the risks that organophosphate pesticides pose to about 1,800 critically threatened or endangered species. This comes after the Administration abandoned plans to restrict the brain-damaging pesticide chlorpyrifos, also an organophosphate pesticide created by Dow, despite mountains of evidence that show the chemical’s neurotoxic impacts on children’s brains. In letters sent to government officials, lawyers for Dow urge Administration officials and the U.S. Environmental Protection Agency (EPA) to set aside “biological evaluations” that detail how three highly toxic organophosphate insecticides –chlorpyrifos, malathion and diazinon– harm nearly all 1,800 threatened and endangered animals and plants, claiming the process to be “fundamentally flawed.” Federal agencies tasked with protecting endangered species –EPA, National Marine Fisheries Service, U.S. Fish and Wildlife Service and U.S. Department of Agriculture– have worked for years to identify the risks posed by pesticides to threatened and endangered species under to the Endangered Species Act (ESA). Under Section 7 of ESA, states that any agency action must find that it “is not likely to jeopardize […]

(Beyond Pesticides, April 7, 2017) On Wednesday, Earthjustice, representing the Natural Resources Defense Council (NRDC) and the Pesticide Action Network North America (PANNA) turned to the courts to order the U.S. Environmental Protection Agency (EPA) to ban chlorpyrifos. Their action comes on the heels of EPA Administrator Scott Pruitt’s decision last week to reject the conclusions of EPA scientists and reverse a proposed agency decision to revoke food residue tolerances of chlorpyrifos. In the new petition, the environmental groups assert that, “Because EPA has sidestepped this Court’s orders and failed to act on the substance of the petition, PAN/NRDC respectfully ask the Court to [give] EPA 30 days to act on its findings that chlorpyrifos exposures are unsafe and to establish deadlines for the next steps in the revocation and cancellation process.” In an interview with The Intercept, Patti Goldman, managing attorney of Earthjustice’s Northwest regional office in Seattle, WA, stated that, “It’s outrageous that the new EPA administrator would reject the scientific findings of its own agency and defy the law and court orders to keep this nasty pesticide on the market.” In its most recent analysis of chlorpyrifos, EPA determined that children between one and two years of age […]

(Beyond Pesticides, March 31, 2017) On Wednesday, Scott Pruitt, the new head of the Environmental Protection Agency (EPA), rejected the conclusions of EPA scientists, and independent scientific literature, and reversed a tentative decision from 2015 to revoke food residue tolerances of chlorpyrifos due to the chemical’s neurotoxic impacts. This would have effectively banned chlorpyrifos from agriculture. This decision stemmed from a petition and lawsuit filed by the Natural Resources Defense Council (NRDC) and Pesticide Action Network North America (PANNA)  ten years ago, calling for EPA to revoke all chlorpyrifos tolerances and cancel all registrations. A Federal Appeals court mandated that EPA take final action by March 31, 2017. Mr. Pruitt’s decision leaves the door open for continued neurotoxic dangers for humans, especially children, who have been shown to be especially vulnerable to chlorpyrifos. Chlorpyrifos is part of the organophosphate (OPs) class of pesticides, which were used in World War II as nerve agents. As potent neurotoxicants, organophosphates are extremely harmful to the nervous system, given that they are cholinesterase inhibitors and bind irreversibly to the active site of an enzyme essential for normal nerve impulse transmission. The scientific evidence of neurotoxic dangers associated with chlorpyrifos exposure is extensive and consistent. Epidemiological data also […]

(Beyond Pesticides, January 23, 2017) Last week, the U.S. Environmental Protection Agency (EPA)  released its final Biological Evaluations of Three Chemicals’ Impacts on Endangered Species, which finds that chlorpyrifos and malathion likely have detrimental effect on 97 percent of all species listed and protected under the Endangered Species Act (ESA), while diazinon adversely affects 78 percent. According to EPA’s release on the subject, this is the “first-ever draft biological evaluations analyzing the nation-wide effects” of these registered chemicals on endangered species after decades of widespread use. The evaluations stem from a legal settlement with the Center for Biological Diversity (CBD) in which CBD sued EPA in April 2014 for its failure to comply with ESA, which requires the agency to carry out consultations with federal wildlife agencies while registering pesticides. According to Nathan Donley, Ph.D., a CBD senior scientist, “We’re now getting a much more complete picture of the risks that pesticides pose to wildlife at the brink of extinction, including birds, frogs, fish and plants. When it comes to pesticides, it’s always best to look before you leap, to understand the risks to people and wildlife before they’re put into use. The EPA is providing a reasonable assessment of those risks, many of which can be […]

(Beyond Pesticides, December 19, 2016) The U.S. Environmental Protection Agency (EPA) last week filed a complaint against a Syngenta research farm in Kauai, Hawaii for exposing a dozen agricultural workers to an unregistered insecticide on the farm in early 2016. Syngenta Seeds, LLC is facing over $4.8 million in fines from EPA for allegedly violating multiple federal pesticide regulations meant to protect agricultural workers. At the time of the incident, 19 agricultural workers went to work on fields freshly sprayed with the insecticide chlorpyrifos, an organophosphate insecticide. The incident with this highly neurotoxic chemical sent 10 workers to the hospital for medical treatment. EPA’s complaint states that Syngenta Hawaii LLC misused the pesticide “Lorsban Advanced” and that violated EPA’s worker protection standard. Due to its neurotoxicity, EPA banned chlorpyrifos for residential uses in 2000, but retained most agricultural use. EPA maintains that Syngenta failed to provide a waiting period for the workers to re-enter the fields. Additionally, Syngenta did not provide workers with personal protective equipment, as well as proper decontamination supplies once the exposure had occurred. At the time of the incident, an inspector from the Hawaii Department of Agriculture (HDOA) was present on the Syngenta farm, which triggered an immediate investigation from the […]

(Beyond Pesticides, December 6, 2016) A new study released by researchers at the University of Washington, Seattle finds that exposure to organophosphate insecticides is associated with changes in oral bacterial diversity, particularly for exposed farmworkers. The study provides insight into the far-reaching changes pesticide exposure can cause to the human body, which are not captured by current risk assessment models used by the U.S. Environmental Protection Agency (EPA). Although past research has investigated the impact of pesticide exposure on the gut microbiome, this is one of the first studies to look at oral bacterial diversity. For the study, scientists took oral swabs from 65 adult farmworkers and 52 non-farmworker adults in the Yakima Valley of Washington State. Swabs were taken both during the spring/summer, when exposure to pesticides is high, as well as winter, when lower exposure is expected. At the same time the swabs were taken, researchers also took blood samples of individuals in the study. Scientists focused on exposure to the organophosphate insecticide Azinphos-methyl (AZM), which at the time of the study (2005-2006) had not begun its cancellation proceedings. Results show that farmworkers have greater concentrations of AZM in their blood than non-farmworking adults in the area. It […]

(Beyond Pesticides, November 15, 2016) Last week, the U.S. Environmental Protection Agency (EPA) updated its assessment of the toxic organophosphate insecticide chlorpyrifos, keeping in place a decision made last year to revoke food residue tolerances and effectively eliminate its use in agriculture. The agency indicated the change was necessary after a Scientific Advisory Panel convened by the agency suggested additional data to support its decision. This change opens up a 60-day public comment period, but EPA has said that it will make a final decision no later than March 31, 2017. “The revised analyses indicate that expected residues of chlorpyrifos on food crops exceed the safety standard under the Federal Food, Drug, and Cosmetic Act (FFDCA),” EPA noted in its announcement.  “In addition, the majority of estimated drinking water exposures from currently registered uses, including water exposures from non-food uses, continue to exceed safe levels even taking into account more refined drinking water exposures. “ To explain the decision to the public, EPA has put together a FAQ page on its website. EPA’s proposal to revoke chlorpyrifos’ food tolerances stems from a petition and lawsuit filed by the Natural Resources Defense Council and Pesticide Action Network North American nearly ten […]

(Beyond Pesticides, July 29, 2016)  A study released earlier this week finds lower IQ (intelligence quotient) in children born to mothers who during their pregnancy were living in close proximity to chemical-intensive agricultural lands where organophosphate pesticides were used. This study adds to the body of scientific literature that links prenatal exposure to organophosphate pesticides with lower IQ’s in children. Organophosphate pesticides, a relatively older generation of highly neurotoxic pesticides still widely used on farms in California, have been associated with a  broad range of diseases  in both children and adults.  This  latest study  supports health and environmental advocates’ call to eliminate these toxic pesticides in agriculture and move toward safer, sustainable, and organic management practices. The study, titled  Prenatal Residential Proximity to Agricultural Pesticide Use and IQ in 7-Year-Old Children, looks at 283 women and children from the agricultural Salinas Valley who are enrolled in the long-term Center for the Health of Mothers and Children in Salinas (CHAMACOS) study. Specifically, researchers looked at pregnant women living within one kilometer of agricultural fields where organophosphate pesticides were used. They found that at age 7, the children of those women had declines of approximately two IQ points and three verbal reasoning […]

(Beyond Pesticides, April 29, 2016) Traces of pesticides, including the long-banned organochlorine chemical DDT, have been found in Western pond turtles, insects, and soil sediment at Sequoia National Park, according to a study.  The study, entitled Organic contaminants in western pond turtles in remote habitat in California  and published in the journal Chemosphere, surveys a suite of 57 current- and historic-use pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in the western pond turtle, along with their potential prey items and habitat. California study sites include Sequoia National Park, Whiskeytown National Recreation Area, and Six Rivers National Forest, all of which are downstream of undeveloped watersheds and varied in distance from agricultural and urban pollution sources. Researchers found that organic pollutants are widespread in the western pond turtle, which has conservation status; that pesticides are prominent in Sequoia National Park, which is downwind of heavy agriculture; and that the legacy  pesticides and PCB concentrations indicate that bioaccumulation is occurring. Brian Todd, Ph.D., an associate professor of wildlife, fish, and conservation biology at University of California Davis, co-authored the study. Dr. Todd said controlling the flow of pesticides into national parks is pretty much impossible. “Sequoia National Park is very […]

(Beyond Pesticides, April 12, 2016) Two commonly used pesticides are “likely to adversely affect” 97% of species listed under the Endangered Species Act (ESA), according to a first of its kind national assessment by the U.S. Environmental Protection Agency (EPA). The determination is part of a settlement reached by EPA and the Center for Biological Diversity, which requires the agency to complete a review of the impact of organophosphate pesticides chlorpyrifos, malathion, and diazinon by December 2017, and two carbamate class pesticides, methomyl and carbaryl, by the end of 2018. Under ESA Section 7, any agency action that it  authorizes, funds, or carries out must find that it  “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” Under ESA, EPA is required to consult with the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) when registering a pesticide, in order to mitigate risks to endangered species. However, EPA routinely disregards this requirement, and has been sued numerous times for failing to ensure adequate protections for endangered species. Although CBD’s original lawsuit targeted potential pesticide impacts on California’s threatened red-legged frog, […]

(Beyond Pesticides, March 4, 2016) Honey bees experience a learning and memory deficit after ingesting small doses of the insecticide  chlorpyrifos, potentially threatening their success and survival, according to a study in  New Zealand. Chlorpyrifos is a highly neurotoxic organophosphate pesticide used worldwide on crops to protect against insects and mites. The study,  Measurements of Chlorpyrifos Levels in Forager Bees and Comparison with Levels that Disrupt Honey Bee Odor-Mediated Learning Under Laboratory Conditions,  published in  Ecology, examines chlorpyrifos levels in  bees collected from 17 locations in Otago, New Zealand and compared doses of the pesticide that cause sub-lethal effects on learning performance under laboratory conditions with amounts of chlorpyrifos detected in bees in the field. Researchers found chlorpyrifos in 17% of the sites sampled and 12% of the colonies examined. Honey bees are found to experience harmful effects to smell memory and learning, and reduction in specificity of memory recall. Chlorpyrifos is just one of many pesticides that have frequently been detected in honey bees. According to a study conducted last year by the U.S. Geological Survey (USGS), 72% of bees tested positive for pesticide residues, raising concerns about  unintended pesticide exposures where land uses overlap or are in proximity […]

 (Beyond Pesticides, January 20, 2016) Aldi SĂĽd, the German supermarket chain with stores in the U.S., has become the first major European retailer to ban pesticides toxic to bees, including the neonicotinoids imidacloprid, clothianidin and thiamethoxam, from fruits and vegetables produced for their stores. Aldi has requested suppliers comply at the earliest possible time. In light of the growing pollinator crisis and due to public pressure, retailers in Europe and the U.S. are slowly beginning to make the switch away from bee-toxic pesticides. Beginning January 1, suppliers of fruits and vegetables to Aldi suppliers will have to ensure that their cultivation practices do not include the following eight pesticides identified as toxic to bees (thiamethoxam, chlorpyrifos,  clothianidin, cypermethrin, deltamethrin, fipronil, imidacloprid and sulfoxaflor) to meet  the new requirement. According to a press release from Greenpeace, the chemicals are used on various commodities in Europe  —thiamethoxam (used in lettuce and endive), chlorpyrifos, clothianidin (used in kohlrabi, herbs, Brussels sprouts, head cabbage, cauliflower and kale), cypermethrin (leek, head cabbage and leguminous vegetables), deltamethrin (cauliflower, peppers, eggplant, zucchini, cucumber, pea, head cabbage, tomato and lettuce),  imidacloprid (applied to apples, peaches, apricots and lettuce). Sulfoxaflor was recently granted regulatory approval in Europe, despite calls […]

(Beyond Pesticides, November 3, 2015) The U.S. Environmental Protection Agency (EPA) is proposing to revoke all food tolerances for the organophosphate insecticide chlorpyrifos (also known as Dursban), a neurotoxic pesticide produced by Dow AgroSciences that poses particular risks to children and farmworkers. If EPA’s rule is finalized, chlorpyrifos would be effectively eliminated from use in agriculture 15 years after consumer uses were discontinued. However, other non-food uses, including golf courses, turf, green house and mosquito control are not affected by this decision and will remain. EPA’s proposed rule came on the day of a court-ordered deadline from the U.S. Court of Appeals Judge for the Ninth Circuit, M. Margaret McKeown. In August of this year, Judge McKeown ordered EPA to respond to a petition filed by Pesticide Action Network North America and the Natural Resources Defense Council nearly nine years ago. The lawsuit called on the agency to ban all uses of the insecticide in light of scientific evidence and public comments ignored by the agency after its cumulative risk assessment for organophosphate insecticides. In 2012, EPA imposed “no-spray” buffer zones around public spaces, including recreational areas, schools, and homes to reduce bystander exposure risks. Earlier this year, the agency […]
