(Beyond Pesticides, August 10, 2018) The U.S. Environmental Protection Agency (EPA) must ban a widely used organophosphate pesticide linked to brain damage in children, the 9th Circuit Court of Appeals ruled yesterday. The appellate court ordered EPA to finalize its proposed ban on chlorpyrifos, produced by DowDupont, based on undisputed findings that the pesticide is unsafe for public health, and particularly harmful to children and farmworkers. The ruling comes in a lawsuit brought by a coalition of labor and health organizations, represented by Earthjustice. In the absence of EPA action, states have started to stand up. In May, the state legislature in  Hawaii passed legislation, which took effect in May, to become the first state to ban the chemical. On July 30, the California Department of Pesticide Regulation (DPR) released its scientific assessment concluding that the organophosphate insecticide, chlorpyrifos, should be listed as a Toxic Air Contaminant (TAC) in the state based on evidence of its neurological effects and exposure risks of concern. Legislation is also pending in Congress to ban chlorpyrifos and similar pesticides nationwide. Chlorpyrifos is a dangerous nerve agent pesticide that can damage the developing brains of children. Prenatal and early life exposure to chlorpyrifos is linked to lower birth weight […]

(Beyond Pesticides, August 8, 2018) On July 30, the California Department of Pesticide Regulation (DPR) released its scientific assessment concluding that the organophosphate insecticide, chlorpyrifos, should be listed as a Toxic Air Contaminant (TAC) in the state based on evidence of its neurological effects and exposure risks of concern. This comes after the 2017 decision by the U.S. Environmental Protection Agency (EPA) reversed its decision to ban the dangerous chemical after intervention by its manufacturer. Decades of scientific data show that chlorpyrifos damages fetal brains and produces cognitive and behavioral dysfunctions, particularly in utero and in children. Even at low levels of exposure chlorpyrifos can impact the developing fetus in pregnant women resulting in impaired learning, change in brain functions, and alter thyroid levels of children into adulthood. A study conducted by the Columbia University Center for Children’s Environmental Health (CCCEH) found that chlorpyrifos in umbilical cord blood samples corresponded with a decrease in the psychomotor and mental development in three-year olds. Additional data collected by CCCEH researchers demonstrated that children exposed to high levels of chlorpyrifos experience developmental delays, attention deficit, hyperactivity, as well as other pervasive developmental disorders. But despite this, and the advice of the agency’s own scientists, EPA, under the direction […]

(Beyond Pesticides, July 17, 2018) Last week, closing arguments were made in the 9th Circuit Court of Appeals challenging the U.S. Environmental Protection Agency’s (EPA) refusal to ban chlorpyrifos, the pesticide science links to a host of neurological impairments in children. A coalition of labor and health organizations represented by Earthjustice asked a panel of three judges to overturn former EPA Administrator Scott Pruitt’s decision not to ban chlorpyrifos. In June 2017, a dozen health, labor, and civil rights organizations represented by Earthjustice filed an administrative appeal to EPA urging the federal government to ban chlorpyrifos. The attorneys general of New York, California, Washington, Massachusetts, Maine, Maryland and Vermont also filed their own appeal calling for a ban. The groups also filed a court case that asked the 9th Circuit Court in San Francisco to decide the issues presented in the administrative appeal because of the likelihood of a delayed resolution by the EPA. This was the last hearing where the health and labor groups, as well as states, were able to present their arguments to the court of appeals and answer the judges’ questions. The New York Attorney General’s office also presented arguments on behalf of seven states, which intervened in […]

(Beyond Pesticides, June 29, 2018) It is widely known that pollinators are in trouble. In light of this, Kroger (which includes numerous other grocery chains, like Harris Teeter) announced in a press release last week — during National Pollinator Week —  a phase-out by 2020 of live garden plants treated with the insecticides most closely associated with the decline of bee populations, the neonicotinoids. In May, Costco updated its pollinator policy, which “encourages” its suppliers of garden plants, fruits, and vegetables to limit the use of bee-toxic pesticides and adopt ecological practices. The company in 2016 announced a policy to encourage suppliers to change their pesticides. In a statement that has broad implications for pollinator and environmental protection, Kroger included the following statement about organic food in its press release: “Kroger also offers one of the largest organic produce departments in America, which is desirable for customers looking to minimize potential exposure to synthetic pesticides. Representing nearly 20 percent of America’s annual organic produce business, Kroger sales reached $1 billion in 2017. A dedicated procurement team partners with more than 300 organic produce growers and suppliers every year to bring customers a growing selection of organic fruits and vegetables.” Costco is also […]

(Beyond Pesticides, May 24, 2018) California’s Department of Pesticide Regulation (DPR) is falling short of protecting vulnerable communities in the state, especially low-income and communities of color. This, according to a new report by California Environmental Justice Alliance (CEJA), which assesses state agencies on eight environmental justice principles. The poor showing by DPR comes at the forefront of reports that the state’s pesticide use has increased, nearing record highs. The findings are from California Environmental Justice Alliance’s (CEJA) 2017 Environmental Justice Agency Assessment, which provides full assessments of nine key agencies in the state including, California Air Resources Board, Department of Pesticide Regulation, and the Department of Toxic Substances Control, and lists an additional six agencies to monitor. The assessment gave the California Department of Pesticide Regulation (DPR) poor grades for its persistent failure to prioritize community health over industry profits. The agencies were judged on eight environmental justice principles, with a score of good, fair or poor for each. DPR’s scores were evenly divided between “fair” and “poor.” Specifically, the report concludes, “Many state agencies are not successfully integrating [environmental justice] into their decision-making. Overall, many state agencies still make decisions that actively harm [environmental justice] communities and fail to […]

(Beyond Pesticides, May 22, 2018)  A staggering 209 million pounds of pesticides were used in California in 2016, according to the latest data released by the Department of Pesticide Regulation (DPR). This figure refers only to applied “active” pesticide ingredients and not “inerts,” which often account for 80 to 99 percent of pesticide products and can be equally hazardous to human health and the environment. Even though pesticide use in the state has dropped by 1.4 percent from the previous year, pesticide use in 2016 was still the third highest in recorded history, since the inception of DPR’s comprehensive data collection program in 1990. In fact, the total pesticide use was only six million pounds shy of the highest amount ever recorded – 215 million pounds in 1998. The land area treated with carcinogens is as large as the size of New Jersey and Connecticut combined. Nearly 102 million cumulative acres of land were treated with pesticides in the state, ranging in toxicity from low to high risk. Each time an acre is pesticide-treated in a given year, DPR adds the acre to its cumulative list, even if the treatment is repeated on the same land. The 2016 figure represents an […]

(Beyond Pesticides, May 3, 2018) Hawaii’s bill to ban the dangerous, neurotoxic pesticide, chlorpyrifos, passed its final hurdle this week in the state legislature. Governor David Ige is expected to readily sign SB3095 into law, in light of the unanimous support it received from lawmakers on both sides of the aisle. The statewide prohibition of chlorpyrifos will take effect beginning in January 2019. This legislative action marks the first time that any state in the country has passed an outright ban on the highly toxic organophosphate pesticide. While multiple scientific studies have determined that chlorpyrifos damages fetal brains and produces cognitive and behavioral dysfunctions, particularly in utero and in children, states have been slow to institute a complete prohibition, due to its widespread use in agriculture. Lawmakers in New Jersey and Maryland have recently tried unsuccessfully to pass similar bans. Hawaii’s bill contains a caveat that allows the state’s Department of Agriculture (DOA) to grant special permits for companies that argue that they need more time to phase-out chlorpyrifos, but that exemption will end at the close of 2022. The new law also requires restricted use pesticide (RUP) users to report to the Hawaii’s DOA which ones they are applying on […]

(Beyond Pesticides, April 13, 2018) Hawaii is poised to become the first state in the nation to prohibit the use of pesticides containing the developmental neurotoxicant, chlorpyrifos. SB3095, passed unanimously by the State House of Representatives this week, prohibits the application of restricted use pesticides (RUPs) within 100 feet of schools when they are in session, and it requires commercial agricultural entities to regularly report their RUP use to the Department of Agriculture (DOA). In the absence of adequate federal procedures to protect communities from hazardous pesticide drift, this bill represents the culmination of efforts by the people of Hawaii to ban and restrict the most egregious pesticides and to increase the transparency regarding their use. As bill supporters rallied in the Capitol’s Rotunda this week, SB3095 was sent to the Senate. No date has yet been set for its consideration, but Senators who support the bill hope to secure the 13 votes needed to pass it and avoid further weakening of its provisions. Beyond Pesticides has actively supported this and previous iterations of SB3095, arguing for the establishment of a much more protective one mile buffer zone between schools and RUP applications to safeguard school children where they learn. […]

(Beyond Pesticides, March 5, 2018) Even if you don’t live in California, chances are that you eat food that is grown there. Unless all that food is organic, some of it was probably sprayed with chlorpyrifos, exposing not only you, but also the farmworkers responsible for its cultivation and harvest. Farmworker families –especially children—who usually live close to the treated fields, suffer higher impacts than those living further away. Tell Governor Brown to ban chlorpyrifos now, for the sake of the children. Five months after the California Department of Pesticide Regulation (DPR) issued its weak and inadequate draft risk assessment for the brain-harming pesticide chlorpyrifos, the state’s Scientific Review Panel (SRP) ordered DPR back to the drawing board to produce a much stronger draft that properly considers the risk of harm to the developing brain. 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 one million pounds of chlorpyrifos on over a million acres […]

(Beyond Pesticides, February 15, 2018) The U.S. Environmental Protection Agency (EPA) settled claims against pesticide giant, Syngenta, after dozens of workers in Kuai, Hawaii were exposed to the neurotoxic pesticide chlorpyrifos in 2016 and 2017. EPA backed away from the $4.8 million settlement that it was initially seeking from Syngenta and negotiated a civil penalty of $150,000. Nineteen workers were exposed to chlorpyrifos after Syngenta sprayed the insecticide on a field of genetically engineered (GE) corn at its Kekaha farm. According to the complaint, the workers were allowed to reenter the field before the reentry period expired and without protective equipment. Ten workers were taken to the hospital and three were held overnight. This incident occurred in 2016, however a second incident occurred in 2017 when Syngenta failed to post warnings for worker crews containing 42 employees after applying chlorpyrifos. 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 state. Consequently, a civil administrative enforcement action was brought against Syngenta seeking $4.8 million for violating multiple federal statues including worker protection standards, allegedly affecting as many as 77 workers and leading […]

(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 ‘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 […]
