(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 […]

(Beyond Pesticides, June 14, 2017)  Oak trees in Iowa may be the latest victim of widespread chemical-intensive agriculture, according reports in the Des Moines Register. The newspaper indicates that the Iowa Department of Natural Resources (IDNR) has received roughly one thousand calls this spring from residents concerned about the state of their oak trees. Leaves are ‘tattered’ down to the vein, in an appearance one would first think was related to pest damage, according to the newspaper article. However, foresters with IDNR indicate the cause is likely the use of chloroacetanillide herbicides, which are applied throughout the state and region. Advocates say that this situation contributes to mounting environmental problems associated with chemical-intensive food production that support the need for the adoption of non-toxic weed management strategies. Past research has found associations between the use of chloroacetanillide herbicides, such as acetochlor and metolachlor, and oak leaf tatter syndrome. State officials indicate that the increase in resident complaints is likely related to a colder March, which may have retarded leaf development. By the time leaves began unfurling in early spring, herbicide use was at its height, leading to high ambient concentrations of the chemicals in the atmosphere, according to IDNR officials […]

(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 12, 2017) Once again, there are reports that soybean and cotton fields are being damaged by off-site drift of the toxic herbicide dicamba. Last summer, farmers in Missouri, Arkansas, and Tennessee reported widespread crop damage from dicamba drift, which led to reduced yields. The U.S. Environmental Protection Agency (EPA) launched a criminal investigation at several Missouri locations into what they said was the illegal spraying of dicamba in October 2016. This year, reports of dicamba drift and damage are already being reported in Arkansas, and 25 formal complaints have already been filed, according to the state Plant Board. In summer 2016, illegal applications of dicamba damaged thousands of acres of soybeans, cotton, ornamental trees and fruits and vegetables. After numerous complaints, EPA launched a criminal investigation into the illegal spraying of dicamba, an investigation that is still ongoing. Many suspect that farmers who planted Roundup Ready 2 Xtend® and XTENDFLEX® Cotton, the new dicamba-tolerant genetically engineered (GE) seeds in the region, when faced with a proliferation of pigweed, illegally sprayed dicamba across their fields leading to drift and off-site crop damage to other farmers. This year, although it is too early to say how many acres have been affected or what specific […]

(Beyond Pesticides, June 9, 2017) Last week, it was revealed that the inspector general for the U.S. Environmental Protection Agency (EPA) is investigating potential collusion on glyphosate-related matters between Monsanto and former EPA official, Jess Rowland. In a letter sent to U.S. Representative Ted Lieu, obtained by HuffPost, EPA Inspector General Arthur Elkins Jr. stated that he has asked the “EPA OIG Office of Investigations to conduct an inquiry into several agency glyphosate review-related matters.” According to Michael Hubbard, a retired Special Agent in Charge for the EPA’s criminal investigations division, in an interview with HuffPost, “Inspectors general have wide-ranging authority to investigate matters of corruption at federal agencies. With confirmation that the IG’s office is taking up a probe, it’s likely that IG investigators will begin interviewing Rowland’s former colleagues and bosses, pulling records and looking through his emails.” In March 2017, Congressman Lieu issued the following statement regarding the released files and questions on glyphosate safety. “Reports suggest that a senior official at the EPA worked to suppress a U.S. Department of Health and Human Services review of glyphosate, and may have leaked information to Monsanto. I believe that a Department of Justice investigation is warranted to look […]

(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, June 7, 2017) Fruit flies that developed a genetic resistance to the insecticide DDT have lower success at mating than those without similar changes, according to a study published last month in the journal Behavior Genetics. The results were surprising to researchers, given that the resistance developed through changes to a single allele (a variation of a single gene). “It is amazing that even if all the genes are exactly the same, having this one gene expressed at a higher level has all these effects,” said Professor Nina Wedell, PhD, of the Centre for Ecology and Conservation on Exeter’s Penryn Campus in Cornwall, UK to Phys.org. The study raises possible concerns about the effect of pesticide exposure to non-target (not the focus of pesticide use) insects that are integral to a healthy ecology and food web. In conducting their investigation, researchers studied the biological fitness costs associated with the development of an insecticide resistance gene. After scientists bred resistant flies in the lab, they set up a series of “competitive mating trials,” comparing both courtship behavior and the impact of size on male fruit flies’ mating success. In general, resistant males were found to be smaller than flies that […]

(Beyond Pesticides, June 5, 2017) Following the recent proposed 10-year extension for the approval of glyphosate use in the European Union (EU), internationally recognized toxicologist Dr. Christopher Portier, Ph.D. has delivered a letter to the European Commission (the Commission), calling the scientific findings of these agencies into question. Dr. Portier is former associate director of the National Institute of Environmental Health Sciences (NIEHS) and director of NIEHS’ Office of Risk Assessment Research. According to the letter, both the European Food Safety Agency (EFSA) and the European Chemicals Agency (EChA) “failed to identify all statistically significant cancer findings in the chronic rodent carcinogenicity studies with glyphosate.” Previously, the Commission, which is in charge of the approval of glyphosate, was forced to issue a limited license extension for the chemical because member states could not reach a consensus. The Commission was holding out for further information on carcinogenicity, which was assessed by the ECHA, and whose report was issued in March 2017. According to ECHA’s most recent assessment, glyphosate is not carcinogenic. Dr. Portier asks that the evaluations by EFSA and EChA be “repeated for all toxicological endpoints and the data underlying these evaluations be publicly released.” Based on these failures in data analysis, […]

(Beyond Pesticides, June 2, 2017) According to a new study, levels of triclosan spike in the bodies of children after they brush their teeth or wash their hands. Triclosan, a controversial antimicrobial, is frequently added to consumer care products. Last year, the Food and Drug Administration (FDA) banned the use of triclosan in hand soaps, but it is still allowed in toothpaste and numerous plastic and textile products regulated by the U.S. Environmental Protection Agency (EPA). Many companies had previously decided, due to consumer pressure, to remove triclosan from hand soaps years ahead of the FDA decision. Researchers collected and tested the urine of 389 mothers and their children –three times during pregnancy, and then took between 1-6 samples from children between the ages of 1 and 8 years old. The researchers found triclosan in over 70% of samples taken. In the group of 8 year olds, they report that levels were 66% higher in the children that used hand soap. For those that wash their hands over five times a day, the levels increase more than four times in comparison to children who wash their hands once or less per day. For toothpaste, researchers find that children who had […]

(Beyond Pesticides, May 31, 2017) Neonicotinoid-treated corn seeds produce lethal and sub-lethal exposure risks to honey bees and do not increase yields for farmers, according to a recent study by researchers at Purdue University. The study, published in the Journal of Applied Ecology, Planting of neonicotinoid-treated maize poses risks for honey bees and other non-target organisms over a wide area without consistent crop yield benefit, examines neonicotinoid (neonic) dust drift during corn planting in Indiana and the likelihood of honey bee exposure during foraging. The study results and subsequent analysis using public data of apiary locations indicate that over 94% of honey bee foragers in Indiana are at risk of exposure to varied levels of neonics, including lethal levels, during corn sowing. Researchers also performed a three-year field assessment of the purported benefits from neonic seed coatings for pest management, finding that there is no evidence of increased corn yields compared to sites with no neonic seed treatments. According to the lead author of the study, Christian Krupke, Ph.D., in an interview with Purdue Extension, “There was a misconception that any bees not living near corn were likely to be fine. But that’s not true, and it’s clear that these […]

(Beyond Pesticides, May 30, 2017) U.S. beekeepers lost an unsustainable 33% of their hives over the past year, according to new data from the Bee Informed Partnership. While this year’s numbers are lower than those recorded last year, which found nearly half of U.S. honey bee colonies died off, there is no cause for celebration. Declines are still well above acceptable loss rates of 15% or less, and the data indicate a continuing trend of substantial losses during the summer months. Without real changes to U.S. policy that effectively eliminate pollinator exposure to highly toxic and persistent pesticides such as neonicotinoids, there is little likelihood that these unsustainable losses will subside. Despite the overall dour projections for U.S. pollinators, Bayer, the major manufacturer of neonicotinoid pesticides implicated in pollinator declines, attempts to spin the news in its favor. Last week, the company put out a press release titled “Welcome News for Honey Bees,” and went on the praise itself for its efforts to protect pollinators. The chemical industry continues to use public relations tactics, in a similar vein to those previously employed by the tobacco industry, to downplay the nature of the crisis, spin the science, and blame everything but […]

(Beyond Pesticides, May 24, 2017) A Hawai’i woman is suing her former employer, DuPont Pioneer, stating that the company retaliated against her for bringing up concerns over pesticide safety. Shanbnell Grilho, who worked for DuPont Pioneer on Oahu’s North Shore, alleges the company required her to apply hazardous herbicides without the proper training or protection, and ultimately fired her after fabricating allegations against her. This lawsuit is the latest claim against multinational pesticide companies operating in Hawai’i, which have been at the center of local and state-level disputes over their use of toxic pesticides where Hawai’i residents live, work, and play. In her complaint, Ms. Grilho indicates that she began working at DuPont Pioneer as a temporary employee, during which time she was awarded a raise and named DuPont Pioneer employee of the month. At the time she did not have to apply pesticides. However soon after her award, she was hired as a full time employee and required to work with Roundup, Liberty, and Honcho herbicides, which contain the active ingredients glyphosate, glufosinate, and glyphosate, respectively.  “DuPont Pioneer required plaintiff to apply herbicides and biocides while wearing a backpack sprayer, driving an ATV while applying herbicides with a backpack […]

(Beyond Pesticides, May 19, 2017) In spite of a growing body of evidence implicating glyphosate in a wide range of human illnesses and environmental impacts, the European Union (EU) plans to propose a 10-year extension for the approval of glyphosate use. Previously, the European Commission (the Commission), which is in charge of the approval, was forced to issue a limited license extension for the chemical because member states could not reach a consensus. The Commission was holding out for further information on carcinogenicity, which was assessed by the European Chemicals Agency (ECHA), and whose report was issued in March 2017. According to ECHA’s assessment, glyphosate is not carcinogenic. Glyphosate is the active ingredient in Monsanto’s Roundup brand of weed-killers, and research by the World Health Organization’s International Agency for Research on Cancer (IARC) has found that it is a probable human carcinogen. Since IARC’s findings were released, Monsanto has made several efforts to discredit the research of this well respected, international body, including attempting to influence government agencies. According to a Bloomberg BNA article, “The commission will discuss with EU member nations the prospect of a 10-year reauthorization, said Anca Paduraru, spokeswoman for the commission.” Once the Commission proposes the […]

(Beyond Pesticides, May 18, 2017) A pesticide reduction plan proposed by investors in the Dr. Pepper Snapple Group (DPS) lacks a positive vision that could accomplish the investors’ goals. The shareholder proposal at DPS, which makes Mott’s, 7UP, Snapple, and Canada Dry, was filed by the Green Century Equity Fund, a company that offers environmentally and socially responsible mutual funds, seeks to pressure DPS to reduce toxic pesticide use in its supply chain. According to their press release, the shareholder proposal suggests that DPS “use quantitative metrics to track the amount of pesticides avoided, publish goals to reduce pesticide use or toxicity, and/or provide incentives to growers to minimize the use of pesticides.” However, the shareholder group could better achieve its goals by asking that DPS use certified organic ingredients. Beyond Pesticides has long sought a broad-scale marketplace transition that does not simply reduce or minimize pesticide use, but prohibits the application of toxic synthetic pesticides by law and promotes the widespread transition of conventional farmland to organic production, which is protective of health and the environment. Certified organic production, with its requirement of a detailed organic system plan and methods to foster and improve soil health, achieves the elimination […]

(Beyond Pesticides, May 17, 2017 Fraud among producers portraying products of chemical intensive agriculture as organic –including those recently identified by the U.S. Department of Agriculture (USDA) Agricultural Marketing Service (AMS) National Organic Program (NOP)— is costly to organic producers and consumers. Imported grains –corn and soybeans that are largely fed to livestock whose products are sold as “organic”— are the focus of claims that USDA is not doing enough to protect the integrity of the organic label. The fraudulent documents that are the subject of the USDA alert are typically produced with the intent to circumvent U.S. organic regulations and are often forged along the supply chain with the goal of increasing the value of agricultural commodities imported to the United States. The arrival of soy and corn crops labeled as organic but later testing positive for residues of pesticides prohibited in organic production, has been well documented in recent years. USDA encourages certifying agents and organic operators to remain vigilant when purchasing organic products from suppliers, and warns of fines for up to $11,000 for anyone found in violation of selling products fraudulently labeled as organic. Additionally, the agency encourages anyone suspecting a violation has been committed to […]

(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, May 11, 2017) On Monday, a federal judge in California ruled that the U.S. Environmental Protection Agency (EPA) violated the Endangered Species Act (ESA) when it issued 59 neonicotinoid insecticide registrations between 2007 and 2012 for pesticide products containing clothianidin and thiamethoxam. The original lawsuit against EPA, Ellis v. Housenger, was filed in March 2013, by beekeeper Steve Ellis and a coalition of other beekeepers and environmental groups, including Beyond Pesticides. The 2013 lawsuit focused on the EPA’s failure to protect pollinators from dangerous pesticides and challenged EPA’s oversight of the bee-killing pesticides, clothianidin and thiamethoxam, as well as the agency’s practice of “conditional registration” and labeling deficiencies. According to George Kimbrell, Center for Food Safety’s legal director and the lead plaintiffs’ counsel, “This is a vital victory. Science shows these toxic pesticides harm bees, endangered species and the broader environment. More than fifty years ago, Rachel Carson warned us to avoid such toxic chemicals, and the court’s ruling may bring us one step closer to preventing another Silent Spring.” The judge presiding over the case rejected claims by pesticide producers and their supporters that the plaintiffs failed to establish a causal link between the pesticides and the […]

(Beyond Pesticides, May 9, 2017) Last month, San Juan Capistrano (SJC) became the latest community in Orange County, CA to pass an organic landscaping policy for city parks and open spaces. The city’s move follows the passage of an organic land care policy in nearby Irvine, CA last year, and like Irvine, was brought forward by a strong contingent of local advocates, health practitioners, and city officials working together to safeguard public health and the environment. By a vote of 4-0-1, San Juan Capistrano’s City Council put the community on the cutting edge of local changes to pesticide use that are taking place across the country. SJC’s policy is the result of persistent pressure and engagement by community group Non-Toxic San Juan Capistrano with city officials. A change.org petition hosted by the group, which received over 300 signatures, detailed the discussions and responses the group received from local leaders. At the time the City Council took up the issue at a mid-April meeting, Mayor Kerry Ferguson made a strong statement indicating that, “Chemical pesticides and herbicides have been proven to be toxic to children, pets, and the general public.” Mayor Ferguson further said, “While [chemical pesticide] use is somewhat limited […]

(Beyond Pesticides, May 5, 2017) Walmart and True Value have announced that beginning on Wednesday they will be phasing out neonicotinoid (neonic) pesticides from all retail supply chains. These announcements follow numerous scientific studies that have consistently implicated neonics in the decline of honey bees and other wild pollinators. The decision stems from an ongoing consumer and environmental campaigns urging retailers to stop selling plants treated with neonics and to remove products containing them from store shelves. Neonicotinoids are systemic pesticides, or whole plant poisons, taken up by a plant’s vascular system and expressed in the pollen, nectar, and dew drops. They are also highly persistent, with research showing the potential for certain chemicals in the class, such as clothianidin, to have a half-life of up to 15 years. Studies show significant cause for concern when it comes to pollinators and exposure to these pesticides. Although little substantive action on these chemicals has been taken by the U.S. Environmental Protection Agency (EPA), the agency agreed that the pesticides do harm bees, though only in the limited situations and constrained scenarios that were actually investigated by EPA. The European Commission (EC) has proposed a complete ban of agricultural uses of the widely used […]

(Beyond Pesticides, May 4, 2017) This week, a study released in the Proceedings of the Royal Society found evidence of reduced egg development and impact on feeding behavior in wild bumblebee queens after exposure to the neonicotinoid thiamethoxam. The study, led by researchers from the University of London, investigates the impact of field-relevant levels of thiamethoxam exposure on four wild species of bumblebee queens. In a BBC News article, lead author, Dr. Gemma Barron, Ph.D., stated, “We consistently found that neonicotinoid exposure, at levels mimicking exposure that queens could experience in agricultural landscapes, resulted in reduced ovary development in queens of all four species we tested. These impacts are likely to reduce the success of bumblebee queens in the spring, with knock-on effects for bee populations later in the year.” The study focuses on sublethal effects of neonicotinoids, as wild bumblebees are more likely to be exposed to low doses of these chemicals, rather than higher lethal levels. The queen bumblebees of four species were collected in the spring of 2014, with a total of 506 being used in the initial study groups. These queens were divided into three treatment groups and exposed to either a high level, low level, or no […]

(Beyond Pesticides, May 3, 2017) Last week, researchers at the University of California San Diego revealed the first ever link between the use of neonicotinoid pesticides and the ability of bees to fly. Published in Scientific Reports, the study, “A common neonicotinoid pesticide, thiamethoxam, impairs honey bee flight ability,” builds on previous findings that neonicotinoid use interferes with bees’ ability to navigate, and concludes that exposure to thiamethoxam affects honey bee flight patterns as well as their physical ability to fly in ways that may be detrimental to their survival. The study is the latest in a growing body of science linking pesticide use to honey bee declines, raising concerns about overall honey bee health and longevity in the face of continued neonicotinoid use. According to the study, both acute and chronic exposure to thiamethoxam revealed significant alterations of the ability of bees to fly -affecting flight distances, duration of flights, and flight velocity. Researchers noted significant differences in bee behavior based on short versus long term exposure, which they summarized as having an “excitatory short-term effect and a depressive longer-term effect” on the bees’ ability to fly. This means that when bees were exposed to thiamethoxam for a short, […]

(Beyond Pesticides, April 27, 2017) Multinational chemical companies Dow Chemical Company and Shell Chemical Company knowingly sold and marketed fumigants contaminated with a cancer-causing chemical that had a strong propensity to leach into and remain in groundwater, according to a recent report from the Environmental Working Group (EWG) and a lawsuit against the companies. The contaminant of concern, 1,2,3-trichloropropene (TCP), was a manufacturing by-product found in Dow’s Telone and Shell’s D-D fumigant pesticide products with the active ingredient 1,3-Dichloropropene. The products, used to kill soil-dwelling nematodes, are toxic in their own right, but contained TCP in their formulation from the 1940s until the mid-1980s. EWG’s report details widespread contamination of drinking water in California’s agricultural regions, with detections found in 562 wells, and 94 public water systems identifying TCP above legal limits. Thirty-seven additional public water systems serving nearly 4 million U.S. residents throughout the country were also found to contain TCP. The U.S. Environmental Protection Agency has never set maximum contaminant levels for TCP in drinking water, but requires public reporting above the infinitesimally small amount of 30 parts per trillion, roughly six times higher than what the state of California requires. However, even proposed limits of 5 parts per trillion […]
