(Beyond Pesticides, October 18, 2017) Effective immediately, the European Parliament has banned Monsanto lobbyists, excluding the chemical company from access to committee meetings and digital resources, as well as no longer permitting Monsanto lobbyists to meet with any Member of the European Parliament (MEP). This limit to its influence is a serious blow to Monsanto’s advocacy campaign to promote the safety of its weedkiller glyphosate, (Roundup). The decision to ban came amid mounting public pressure to deny European Union re-licensing of glyphosate, one of the world’s most widely used herbicides. (See glyphosate listing in Beyond Pesticides’ Pesticides Gateway, the active ingredient in Monsanto’s Roundup herbicide.) Glyphosate is classified as “probably carcinogenic to humans” by the World Health Organization’s International Agency for Research on Cancer (IARC). Monsanto, the world’s largest GE-seed and seventh-largest pesticide company, is eager to suppress IARC’s ranking. In fact, before being banned, the European Parliament had questioned Monsanto’s funding of counter-studies in order to discredit independent scientists working to limit the public’s exposure to toxic chemicals. In a related development, independent scientists sent a letter to the scientific journal Critical Reviews in Toxicology, calling for the retraction of a 2016 paper that refuted glyphosate’s cancer risks after it was learned that […]

(Beyond Pesticides, October 17, 2017) In a letter to the scientific journal Critical Reviews in Toxicology, scientists called for the retraction of a 2016 paper that refuted glyphosate’s cancer risks after it was learned that the paper was secretly edited and funded by Monsanto, manufacturer of glyphosate. The paper in question, “An Independent Review of the Carcinogenic Potential of Glyphosate,” is a review of the 2015 decision by an expert Working Group of the International Agency for Research on Cancer (IARC) to designate glyphosate, the active ingredient in Monsanto’s flagship product, Roundup, as “probably carcinogenic to humans” (Group 2A). However, a new report this summer discovered conflict of interests not revealed at publication. Contrary to the journal’s conflict-of-interest disclosure statement, Monsanto directly paid at least two of the scientists who authored the paper, and a Monsanto employee substantially edited and reviewed the article prior to publication, in clear contradiction to the disclosure statement. The retraction-request letter highlights a range of failures involved in the published review: Failure to disclose that at least two panelists who authored the review worked as consultants for, and were directly paid by, Monsanto for their work on the paper. Failure to disclose that at least […]

(Beyond Pesticides, October 11, 2017) Last week, the Natural Resources Defense Council (NRDC) filed a lawsuit challenging the U.S. Environmental Protection Agency’s (EPA) registration of neonicotinoid pesticides – acetamiprid, dinotefuran, and imidacloprid, and the agency’s failure to first consult with the U.S. Fish and Wildlife Service on the pesticides’ impact on threatened or endangered species. The lawsuit, filed in the U.S. District Court for the District of Columbia, challenges the failure of the federal government to evaluate the impacts of neonicotinoid pesticides (“neonics”) on threatened and endangered species, like the rusty patched bumble bee, the black-capped vireo, and the San Bruno elfin butterfly. The suit cites widespread presence of neonics in the environment which presents serious risks to wildlife across large portions of the country. It contends that they pose significant adverse consequences to threatened and endangered species. According to the lawsuit, because of toxicity and pervasive environmental contamination, NRDC is now challenging EPA’s registrations of pesticide products containing one of three main neonic active ingredients—acetamiprid, dinotefuran, and imidacloprid—and seeks vacatur of those registrations until EPA complies with the law. “The EPA ignored endangered bees, butterflies, and birds when it approved the widespread use of neonics,” said Rebecca Riley, a senior […]

(Beyond Pesticides, October 2, 2017) Elementary school students at New York City’s PS 290 are taking a stand against toxic pesticide use in New York City parks, supporting Intro 800, a bill introduced by Manhattan Councilmember Ben Kallos. “We’re going to make a great big fuss,” the children in Mrs. Paula Rogivin’s kindergarten class chanted in a skit performed in front of the NYC Committee on Health this week. Since New York City (NYC) passed Local Law 37, Pesticide Use by City Agencies, in 2005 to stop toxic pesticide use on City owned and leased land, it turns out that some pesticides known to be hazardous were not captured by the law. As a result, the proposed legislation is intended to strengthen restrictions to ensure more comprehensive restrictions that limit pesticides to biological pesticides. Local Law 37 restricts the use of acutely toxic and carcinogenic pesticides as defined by the U.S. Environmental Protection Agency (EPA), and developmental toxicants as defined by the state of California under Prop 65. Exemptions allowing the use of these pesticides are granted based on a waiver review process that requires evidence that the chemicals are necessary to protect public health. Otherwise, City agencies are encouraged […]

(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 […]

EU(Beyond Pesticides, August 16, 2017) Millions of eggs and egg products have been pulled from supermarket shelves in 15 countries in Europe after it was discovered that the eggs were contaminated with the insecticide fipronil. Now,  the European Commissioner in charge of food safety has called for a meeting of ministers and national regulatory agencies to discuss the widespread European contamination. However, fipronil is not allowed for use in food production in Europe, raising concerns over food safety and regulatory oversight. This incident reminds U.S. consumers about the disarray of the U.S. food safety system, as reported by the U.S. Government Accountability Office (GAO) in 2014. According to the GAO report, Food Safety: FDA and USDA Should Strengthen Pesticide Residue Monitoring Programs and Further Disclose Monitoring Limitations, there is a lack of government coordination on food safety and the U.S. Food and Drug Administration (FDA) does not test food for several commonly used pesticides with established tolerance levels. The report sounds an alarm that GAO began sounding  in the 1980’s in several reports that identify shocking limitations of  FDA’s approach to monitoring for pesticide residue violations in food. (See Beyond Pesticides’ coverage.) Since that report, FDA announced, then withdrew its announcement, […]

(Beyond Pesticides, August 15, 2017) With increasing scientific understanding about the importance of beneficial bacteria in soil and the human body —microbiota in the soil and microbiome in the human gut, the summer 2017 issue of Beyond Pesticides’ journal, Pesticides and You, publishes two critical articles to advance the importance of community discussion and action on organic and sustainable practices. The lead article, Sustaining Life: From Soil Microbiota to Gut Microbiome by professor of geomorphology (University of Washington) and author David Montgomery, PhD, contains excerpts from Dr. Montgomery’s talk to Beyond Pesticides’ 35th National Pesticide Forum, documenting the importance of soil microbiota to healthy soil, resilient plants, and sustainability. His piece explains the essentiality of bacteria in the human gut to a healthy life, with profound implications for both agriculture and medicine. Dr. Montgomery points to a “bonafide scientific revolution” in recognizing the failure to nurture the ecosystem in nature and the human body and the associated adverse health effects resulting from pesticide use –21st century diseases, including asthma, autism, bacterial vaginosis, cardiovascular disease, cancer, Crohn’s disease, depression, inflammatory bowel disease, leaky gut syndrome, multiple sclerosis, obesity, Type 1 and 2 diabetes, and Parkinson’s. Also in the Journal, Monsanto’s Roundup (Glyphosate) […]

(Beyond Pesticides, August 11, 2017) On August 1, a second round of internal Monsanto documents became public, stirring up additional questions and speculation about Monsanto’s potential malfeasance — i.e., its efforts to hide information about impacts of its popular glyphosate-based herbicide, Roundup. This follows on the heels of the March 2017 unsealing, by federal judge Vince Chhabria, of internal Monsanto documents — the “Monsanto Papers” — that evidenced questionable research practices by the company, inappropriate ties to a top EPA official, and possible “ghostwriting” of purportedly “independent” research studies. This latest release, of more than 700 documents, came courtesy of Baum, Hedlund, Aristei & Goldman, one of many law firms representing thousands of families who claim that exposure to Roundup caused non-Hodgkins lymphoma (NHL), a blood cancer, in their loved ones. Such litigation has been triggered, in part, by the 2015 finding of the International Agency for Research on Cancer (a branch of the U.N.’s World Health Organization) that glyphosate is “probably carcinogenic to humans.” The plaintiffs allege that the combination of glyphosate and surfactants used in Monsanto’s Roundup products is even more toxic than glyphosate alone, and that Monsanto has sought to cover up that information. Monsanto has continued to […]

(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, July 21, 2017) A March 2017 review of studies on the agricultural use of glyphosate (the active ingredient in “Roundup” and other formulated herbicides) points to widespread persistence in soils subject to long-term, intensive glyphosate use, and myriad resulting concerns about impacts on soil and environmental health. The review, by Robert J. Kremer, PhD, of the University of Missouri School of Natural Resources, cites concerns that include: reduction of nutrient availability for plants and organisms; disruption to organism diversity, especially in the areas around plant roots; reductions of beneficial soil bacteria; increases in plant root pathogens; disturbed earthworm activity; reduced nitrogen fixing at plant roots; and compromised growth and reproduction in some soil and aquatic organisms. Globally, glyphosate is the most widely used herbicide compound: in 2017, worldwide use is estimated to be approximately 1.35 million metric tons. Use in the U.S. has risen dramatically — from 2.72–3.62 million kg in 1987 to approximately 108 million kg in 2014, and 15-fold since 1996, when genetically engineered (GE) glyphosate-tolerant crops were introduced. Use has grown for a number of reasons, including more-intensive use as resistance to the herbicide grows. Researchers have found that, after years of consistent application to […]

(Beyond Pesticides, July 20, 2017) In its recently released 2017 Preliminary Aquatic Risk Assessment for Imidacloprid, the U.S. Environmental Protection Agency (EPA) found that this neonicotinoid insecticide is not only toxic to bees but also, is destroying life in the nation’s streams, rivers, and lakes. This assessment finds that aquatic invertebrates, especially aquatic insects basic to aquatic food chains, are sensitive to imidacloprid, and that current imidacloprid levels detected in streams, rivers, lakes, and drainage canals exceed acute and chronic toxicity endpoints. Impacts occur at low concentrations, and can result in decreased species abundance, altered predator-prey relationships, and reduced nutrient cycling. Impacts to other wildlife that depend on these species raise serious cause for concern. Comment by July 24 and tell EPA to cancel these neonicotinoids to protect sensitive species and ecosystems. See sample comment language, below. Clothianidin, thiamethoxam, and dinotefuran are too toxic for honey bees and native bees EPA also finds that the other neonicotinoids –clothianidin, thiamethoxam, and dinotefuran– pose risks to bees both on and around treated fields, but the agency has not evaluated risks from soil, surface water, or contaminated seed dust, which underestimates exposure risks and continues to put our native bees at risk. Clothianidin and thiamethoxam are […]

(Beyond Pesticides, July 13, 2017) Over the past week, both Arkansas and Missouri issued bans on the sale and use of the weedkiller dicamba by farmers because of crop damage associated with the pesticide’s drift off treated fields. On Friday, July 7, the Arkansas Agriculture Department announced this emergency 120-day ban, which raised civil penalties for misuse of the toxic herbicide from $1,000 to a maximum of $25,000. The same day, the Missouri Department of Agriculture announced a temporary “Stop Sale, Use or Removal Order” on all dicamba products in the state labeled for agricultural use. Dicamba has been linked to damage of the kidney and liver, neurotoxicity, and developmental impacts. The chemical has a strong propensity to volatilize small particles of the herbicide into the air and drift far off-site. Sensitive crop species can be damaged by dicamba at levels in the parts per million. As of July 7, nearly 600 complaints of dicamba danage have been filed by Arkansas farmers in 23 different counties. In Missouri, as of July 3, there are 123 cases of dicamba injury complaints under investigation and according to the Missouri Soybean Association, “more than 200,000 Missouri soybean acres currently show signs of suspected dicamba […]

(Beyond Pesticides, July 11, 2017) South Florida resident Michael Hall, M.D., filed an emergency request in federal court last week to block Miami-Dade County’s continued use of the organophosphate insecticide naled to control mosquito populations. There have been two rounds of aerial naled applications in Miami-Dade this year. Widespread use of the chemical in efforts to control the transmission of Zika last year prompted protests from residents complaining of health effects from the spraying, and calls to focus on less toxic, alternative methods of mosquito breeding prevention and control. The present use of naled in Miami-Dade is not focused on Zika control, but addressing the native salt marsh mosquito, which does not transmit human diseases, but can be a significant nuisance in shoreline areas. According to WLRN, officials are no longer using naled for Zika control as the mosquito species that carries it, Aedes aegypti, usually stays well hidden under vegetation and shrubbery. A study released last year confirmed that the county’s use of naled did little to reduce mosquito populations. “Naled, a potent organophosphate adulticide applied aerially, produced a transitory suppression in Wynwood but lost efficacy after two or three applications. In Miami Beach, aerial application of naled produced […]

(Beyond Pesticides, July 10, 2017) The state of California has listed glyphosate, the active ingredient in the popular Roundup, as a known carcinogen under its Proposition 65 law. This listing went into effect July 7, 2017. Now, state officials have to develop guidelines for product labels and determine what level of exposure to the pesticide will put people at risk for developing cancer. Some have argued that the state’s proposed levels are not protective enough. Meanwhile, the state continues to face pressure from Monsanto, maker of glyphosate, which continues to challenge the decision to list the chemical as a known cancer-causing agent. California’s decision to list glyphosate as a carcinogen was prompted by the International Agency for Research on Cancer’s (IARC) finding in 2015 that it is a “probable” human carcinogen. This classification was based on sufficient evidence of carcinogenicity in experimental animals. Later that year, California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced that it intended to list glyphosate as a cancer-causing chemical under California’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).  Under California law, Proposition 65 requires that certain substances identified by IARC be listed as known cancer-causing chemicals. Glyphosate’s listing became effective […]

(Beyond Pesticides, July 7, 2017) The active ingredients in commonly used bug sprays such as RAID leave significant residues that persist for over a year in the home, according to a study published by Brazilian researchers in the journal Environmental Toxicology and Chemistry. The pesticides tested, synthetic pyrethroids, have been linked to a range of health effects, most notably in children. The results of this study add to calls for homeowners to rethink a chemical-based approach to home pest control, in favor of simple, non-toxic practices. In the recent study, researchers compared the breakdown time of two synthetic pyrethroids, cypermethrin and beta-cyfluthrin, between laboratory conditions and those in an average home. Under lab conditions, with temperature controlled and without sunlight or ventilation, both active ingredients broke down little within the 112 day test period observed. However, the test house, where insecticides were applied according to indoor label conditions, displayed breakdown times similar to the lab results during the first 112 days. Researchers continued their observation of pyrethroids in the home for up to a year, finding after that period 44% of beta-cyfluthrin and 70% cypermethrin remained in household dust samples from the singular, original application. A 2014 study published by […]

(Beyond Pesticides, July 6, 2017) The Washington State Department of Ecology (Ecology) is evaluating a new permit application for the use of imidacloprid, a toxic neonicotinoid, to combat a growing native population of burrowing shrimp that threatens oyster beds in Willapa Bay and Grays Harbor in Washington state. The application was recently submitted to Ecology by a group of oyster farmers from the Willapa Grays Harbor Oyster Growers Association (WGHOGA), who “propose to use the pesticide to treat tide lands to support their aquaculture practices.” Imidacloprid is known to be toxic to bees and aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. In April 2015, much to the dismay of activists and concerned local residents, Ecology approved a permit submitted by oyster farmers for the use of imidacloprid to combat burrowing shrimp in these aquatic ecosystems. But with a nationwide public outcry, the permit was withdrawn in May 2015. The recent request that was submitted differs in several ways from this 2015 permit, including: The new permit proposes treating 485 acres in Willapa Bay and 15 acres in Grays Harbor, compared to 2,000 acres combined from both water bodies in the 2015 permit. The oyster farmers […]

(Beyond Pesticides, July 3, 2017) A two-year long study conducted at 33 sites in multiple European countries to assess the effects of neonicotinoid (neonics) insecticides on three bee species in real-world environmental conditions confirms that these pesticides have a deleterious effect on bee survival. The study, the largest of its kind, explored the role of the agricultural use of neonics as seed coatings on bee health and fnds that the pesticides are persistent in the environment, contaminating pollen and nectar that bees forage, reducing colony fitness. The results of the study support ongoing calls for a ban on neonics, including a European Union (EU) wide ban proposed earlier this year. The new research, published in the prestigious peer-review journal Science, which was in part funded by Bayer and Syngenta – manufacturers of the pesticides, encompassed large field experiments to assess the effects of neonic-treated crops on various bee species –honey bees (Apis mellifera), bumble bees (Bombus terrestris), and solitary bees (Osmia bicornis)– across three European countries (Germany, Hungary and the United Kingdom). The study examines the impacts of clothianidin and thiamethoxam, the neonics frequently used as seed coatings of oil seed rape (canola), and used in the fields under study. […]

(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 27, 2017) French Prime Minister, Edouard Philippe, is retaining the neonicotinoid (neonic) pesticide ban, which is set to go into effect in 2018 and is stronger than the current European Union restrictions on neonics. This decision follows a disagreement with French Agriculture Minister, Stephane Travert, who was in favor of relaxing the ban and told media outlets that he wants to address “the possibility of a number of exemptions until we find substitution products.” In July 2016, lawmakers in France approved plans to ban neonicotinoid pesticides by 2018, based on their link to declining populations of pollinators, specifically bees. The outright ban on neonicotinoid pesticides in France was adopted by a narrow majority of the country’s National Assembly, as part of a bill to protect biodiversity. In March 2017, the European Commission (EC) proposed a complete ban of agricultural uses of the widely used bee-toxic neonicotinoid pesticides across Europe under draft regulations. The EC cites neonicotinoids’ “high acute risks to bees.” In 2013, three neonicotinoids were temporarily banned because of concerns about their high toxicity to bees. A vote by member states is still being awaited. In 2013, the European Commission voted to suspend the use of the neonicotinoid pesticides […]

(Beyond Pesticides, June 22, 2017) On Tuesday, a lawsuit was filed in a Wisconsin federal court against Monsanto, the manufacturer of Roundup brand herbicides, and Scotts Miracle-Gro Company, a marketer of Roundup brand products. The complaint, filed by six consumers from states around the country, focuses on the promotion, marketing, and sale of Roundup brand products, rather than physical injury from the pesticide products. The lawsuit alleges that the Monsanto and Scotts label, advertise, and promote their Roundup products with the “false statement that Roundup’s active ingredient, glyphosate, targets an enzyme that is not found ‘in people or pets.’” Plaintiffs assert that this is a false and deceptive claim, as this enzyme is found in the gut bacteria of people and pets and glyphosate can disrupt the health and functioning of their immune system. This suit follows on the heels of and mirrors the lawsuit filed by Beyond Pesticides and Organic Consumers Association in April 2017 against Monsanto for misleading the public by labeling the weedkiller Roundup as “target[ing] an enzyme found in plants but not in people or pets.” Monsanto aggressively markets Roundup as safe for humans and animals, despite newer studies indicating that glyphosate may be carcinogenic and affect […]

(Beyond Pesticides, June 21, 2017) More than 200 international scientists and medical professionals have signed the Florence Statement on Triclosan and Triclocarban, which states that triclosan and its chemical cousin triclocarban pose a risk to human health, and urges the international community to limit use of these antimicrobials, which are associated with bacterial resistance and no more effective than soap and water. In 2016 after manufacturers failed to prove efficacy, the U.S. Food and Drug Administration (FDA), which regulates cosmetic triclosan products, announced that manufacturers must, by September 2017, remove triclosan from over the counter hand soaps. The agency still allows the chemical in toothpastes and other products, such as hand wipes. The Environmental Protection Agency (EPA), which regulates triclosan in household items, textiles and plastics, still permits wide use of the chemical in a range of products. The Florence Statement on Triclosan and Triclocarban is “based on extensive peer-reviewed research,” and “concludes that triclosan and triclocarban are environmentally persistent endocrine disruptors that bioaccumulate in and are toxic to aquatic and other organisms.” The statement includes evidence of human health threats, and provides recommendations intended to mitigate harm from triclosan, triclocarban, and other similar antimicrobials. The recommendations are listed below: “Avoid […]

(Beyond Pesticides, June 15, 2017) Communities exposed to frequent aerial spraying for mosquito control experience elevated rates of autism diagnoses, according to new research. The study identifies the frequent use of synthetic pyrethroid insecticides, which are linked to neurocognitive and behavioral impacts, among other health effects. Pediatric researchers at Penn State University and the University of California examined communities in eight zip codes in Onondaga County, New York with frequent aerial spray programs for mosquito control, and contrasted these findings with communities in 16 zip codes that do not employ similar pesticide use programs. According to the study, between 2007 and 2009, the average yearly pesticide burden across the eight aerial exposed zip codes was approximately 11,000 kilograms, compared to approximately 4,000 kilograms of pesticide exposure across the 16 control zip codes. The study finds that the zip codes with frequent aerial pyrethroid exposure are 37% more likely to have higher rates of childhood developmental delays and autism spectrum disorder. The researchers acknowledge that the study establishes a correlational, not a causal, link between pyrethroid exposure and autism/developmental disorders, it adds to a growing body of research demonstrating an exposure-effect relationship between the two. Other studies have similarly linked developmental disorders and autism […]
