(Beyond Pesticides, October 9, 2019) Pesticide industry propaganda promoting the safety of glyphosate-based herbicides took another hit last month, as a study published by an international team of researchers found the chemical had the potential to induce breast cancer when combined with other risk factors. The study, Glyphosate Primes Mammary Cells for Tumorigenesis by Reprogramming the Epigenome in a TET3-Dependent Manner, led by scientists from Indiana’s Purdue University and the Institut National de la Santé et de la Recherche Médicale (INSERM)/Institut de Cancérologie de L’Ouest (ICO) in Nantes, France, provides an important new lens through which to view pesticide-induced cancer development. “This is a major result and nobody has ever shown this before,” says Sophie Lelièvre, PhD, a professor of cancer pharmacology in Purdue’s College of Veterinary Medicine and co-leader of IBCN. “Showing that glyphosate can trigger tumor growth, when combined with another frequently observed risk, is an important missing link when it comes to determining what causes cancer.” To make their determination, scientists exposed human breast cells low levels of glyphosate every three to four days over the course of 21 days. A control group was also dosed with a known cancer-promoting peptide. Glyphosate caused the same changes to exposed cells as […]

(Beyond Pesticides, September 24, 2019) In 2016, Canadians and Americans residing in Havana reported symptoms of headaches, dizziness, nausea. They described hearing strange buzzing and high-pitched sounds – some woke in the middle of the night fumbling for alarm clocks that were not going off. Media used the term “Havana syndrome” to describe the illness. Diplomats, scared by symptoms that seemed to only hit them in their hotel rooms or at home, speculated that a sonic weapon was being used against them. The Trump administration accused Cuban leaders of misconduct and removed all but essential employees. Later, some suspected that the diplomats could have experienced “mass hysteria.” A new Canadian study provides a more likely explanation to this mysterious illness that impacted diplomats in Havana: neurotoxic pesticide exposure. Researchers conducted testing on 14 individuals who had resided in Havana and a control group of 12 that had never lived there. Some of the experimental group had been recently exposed while others, tested 19 months after their return, were classified as “remotely exposed.” Tests included brain imaging and self-reported symptom questionnaires. They analyzed blood samples for routine biochemistry, kidney, liver, and metabolic functions. Individuals that showed symptoms of brain injury went […]

(Beyond Pesticides, September 11, 2019) Germany is the latest entity to take action on getting glyphosate-based pesticides out of the marketplace. Chancellor Angela Merkel has announced that, beginning in 2020, the country will phase out herbicides that contain glyphosate by the end of 2023. The phase-out will occur through a series of scheduled reductions in amounts allowed for use, with a goal of a 75% reduction over the next four years. The announcement comes after “nation-wide protests and demands from [Merkel’s] junior coalition partner, the Social Democrats, for more decisive action on environmental issues.” This action stands in telling contrast to the U.S. Environmental Protection Agency’s (EPA’s) repeated failures to protect people, ecosystems, and our food supply, from this toxic compound. The German government also plans to oppose any European Union (EU) request for renewal of licensing of these herbicides, according to the environment ministry. Bayer AG, maker of glyphosate-based herbicides and owner of original manufacturer Monsanto, has pushed back, saying that the government is “getting ahead of itself” by banning glyphosate-based herbicides prior to any decision by the relevant EU authority, and that EU laws disallow unilateral decisions by member states. (Pesticide licensing decisions lie with EU governance in Brussels, […]

(Beyond Pesticides, September 4, 2019) Sixteen organizations representing health, environmental, farmer, and farmworker communities joined together yesterday to call on EPA to remove glyphosate from the marketplace. The groups cite a combination of high-profile lawsuits, environmental impacts, increasing reports of weed resistance, and growing public concern over the health effects of glyphosate in their comments on EPA’s interim reregistration review decision for the chemical. The comments warn that EPA is at risk of damaging the public’s trust in the agency’s review process for toxic pesticides. “EPA’s myopic review and response to the dangers posed by glyphosate does a disservice to American farmers, farmworkers, and commercial landscapers wishing to use least-toxic products that do not put them at risk of health impacts, and consumers aiming to make the safest choice in regards to what to feed their family and how to manage their yards,” the comments read. The document likewise replies to EPA’s attacks against the World Health Organization’s International Agency for Research on Cancer (IARC), which determined glyphosate to be a probable carcinogen based on sufficient evidence of carcinogenicity in experimental organisms. EPA has indicated that its process for evaluating glyphosate, “…is more transparent than IARC’s process” and that IARC’s […]

(Beyond Pesticides, August 30, 2019) The indictment of organophosphate pesticides gained more traction with the publication, in the Proceedings of the National Academy of Sciences, of a new research study out of the University of California, Berkeley. The research, among the first to use advanced brain imaging to assess cortical activation, shows altered brain activity, during tasks that call on executive function, in teenagers from California’s Salinas Valley (the site of significant organophosphate use) whose mothers were exposed prenatally. The UC Berkeley study underscores the slow-motion calamity of the Trump administration Environmental Protection Agency’s (EPA’s) failure to ban the use of this class of pesticides, and of chlorpyrifos in particular, which compounds carry extreme risks for children. The effects of this prenatal exposure continue to unfold during children’s critical developmental periods. Researchers used fNIRS (functional near-infrared spectroscopy) imaging to monitor blood flow in the brains of the teens, 15–17, born and raised in the Salinas Valley. They used data from the California Pesticide Use Reporting program (which documents locations and times of pesticide spraying) to estimate the subjects’ mothers’ proximity to organophosphate (OP) applications during pregnancy. The subject adolescents — estimated to have relatively high levels of prenatal exposure to organophosphates — […]

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

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

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

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

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

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

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

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

(Beyond Pesticides, June 7, 2019) Fruit orchards and vineyards endure some of the most intensive chemical management in all of agriculture. What has not been investigated — until now — is how pesticide drift from such agricultural sites may be affecting nearby public spaces. A recent, first-of-its-kind study out of northern Italy tested 71 public playgrounds near to apple orchards and vineyards in four valleys of the North Tyrol, and finds that 45% are contaminated with a single pesticide, and 24% by more than one. Study authors note that the playground contamination will likely grow worse over the course of the growing season. This would likely amplify the impacts of such chemical trespass on nearby public spaces, never mind the varieties of harm to the sites themselves and the food produced on them. Organic agriculture, of course, remedies all these concerns. The study randomly chose 71 public playgrounds in the four South Tyrolean regions, and analyzed grass samples for potential contamination by 315 different pesticides. Because pesticides applied to agricultural fields, orchards, and vineyards are easily volatized, carried aloft by wind, and/or washed by rain off of the target site, the study also evaluated the impacts of those (and other) factors […]

(Beyond Pesticides, June 4, 2019) A class-action lawsuit is accusing Starbucks stores in New York of misusing a highly toxic, carcinogenic pesticide near food, putting the health of customers and employees at risk.  “Stores throughout Manhattan have for many years been permeated with a toxic pesticide called Dichlorvos [DDVP], which is highly poisonous and completely unfit for use in proximity to food, beverages and people,” the suit reads. According to the lawsuit, Hot Shot brand No Pest Strips were placed in food areas in violation of labels that prohibit the pesticide’s use in “the food/feed areas of food/feed processing or food/feed manufacturing or food/feed service establishments.” A pest control operator found the illegally placed products on a number of separate occasions, hidden under bagels or in pastry display cases, during a five year period from 2013 to 2018. This was not at only one location, but appeared to be a common occurrence at nearly every one of the 100+ stores serviced by the pest control operator. The case brings to light a number of issues with the use of synthetic pesticides. The unsanitary conditions permitted to persist within Starbucks stores, per the pictures provided in the suit (see page 14), […]

(Beyond Pesticides, May 23, 2019) Glyphosate weed killers may be contributing to the growing worldwide epidemic f non-alcoholic fatty liver disease (NAFLD), a condition that causes swelling of the liver, and can eventually lead to cirrhosis, cancer, or liver failure. Researchers at the University of California (UC) San Diego found that higher levels of glyphosate detected in urine corresponded significantly with individuals that have also been diagnosed with NAFLD. Advocates are urging lawmakers at every level to respond to the accumulating science on the danger of glyphosate herbicides, ban their use, and adopt policy changes that put into place organic land management practices. “There have been a handful of studies, all of which we cited in our paper, where animals either were or weren’t fed Roundup or glyphosate directly, and they all point to the same thing: the development of liver pathology,” said Paul J. Mills, PhD, professor and chief in the Department of Family Medicine and Public Health at UC San Diego School of Medicine in a press release. “So I naturally thought: ‘Well, could it be exposure to this same herbicide that is driving liver disease in the U.S.?’” Dr. Mills and his team received urine samples from […]

(Beyond Pesticides, May 20, 2019) The bans of chlorpyrifos in three important agricultural states show the support for a ban of the chemical nationwide. Hawai’i banned chlorpyrifos a year ago with a unanimous vote of the legislature. New York and California banned it this month. States have been pursuing bans since the Environmental Protection Agency rescinded its proposed ban in 2017. Tell Your Governor to Ban Neurotoxic Pesticides and Support Organic; Send Thanks to Your Governor in Hawai’i, New York, and California Like other organophosphate pesticides, chlorpyrifos has been linked to damaging and often irreversible health outcomes in workers, pregnant women, and children. A widely used pesticide, agriculture companies annually spray six million pounds on crops like citrus, apples, and cherries.  In the same family as Sarin gas, the substance was initially developed prior to World War II as a chemical weapon. It can overstimulate the nervous system to cause nausea, dizziness, and confusion. With very high exposures (accidents or spills), it can cause respiratory paralysis and even death. When applying the chemical to fields, workers must wear protective garments such as respirators. Workers are then blocked from entering the fields from 24 hours up to 5 days after application due to the chemical exposure risk. A group of leading toxics […]

(Beyond Pesticides, May 15, 2019) On Monday, a California jury awarded plaintiffs in the third federal Roundup case over $2 billion in punitive and compensatory damages. The jury found that Monsanto “engaged in conduct with malice, oppression or fraud committed by one or more officers, directors or managing agents of Monsanto.” Plaintiffs Alva and Alberta Pilliod, a married couple in their seventies, used Roundup weed killer since the 1970s to maintain their yard and other owned properties. The couple did not wear protective gear when using Roundup because Monsanto marketed the product as “safe.” Alva was diagnosed with non-Hodgkin’s lymphoma (NHL) in 2011; Alberta’s diagnosis followed in 2015. The Pilliod v. Monsanto jury came to their decision based on evidence, not only of the herbicide’s carcinogenicity, but also of Monsanto’s role in suppressing and discredit.ing independent findings regarding Roundup toxicity. In an interview with U.S. Right to Know’s Carey Gillam, co-lead trial counsel Michael Miller said, “Unlike the first two Monsanto trials, where the judges severely limited the amount of plaintiffs’ evidence, we were finally allowed to show a jury the mountain of evidence showing Monsanto’s manipulation of science, the media and regulatory agencies to forward their own agenda despite […]

(Beyond Pesticides, May 9, 2019) On Wednesday, the U.S. Environmental Protection Agency (EPA) issued a proposed interim decision on glyphosate’s registration review, ignoring widespread scientific consensus on the herbicide’s carcinogenicity and instead restating the agency’s firm position that glyphosate is “not likely to be carcinogenic to humans.” EPA’s bold statement stands in stark contrast to scientific consensus to the contrary. In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) found glyphosate to be a probable human carcinogen. In response to resistance from the European Food Safety Authority, 94 expert scientists published an article in support of IARC’s methodologies and findings. Since 2015, several more publications have added significant weight to the body of evidence supporting glyphosate’s carcinogenicity. A February 2018 meta-analysis of studies on glyphosate suggested “a compelling link between exposures to GBH [glyphosate-based herbicides] and increased risk of NHL [non-Hodgkin lymphoma]. A February 2019 University of Washington study found that glyphosate increased the risk of non-Hodgkin lymphoma by as much as 41%. Despite attempts by current and former EPA top officials to “kill” their report, Agency for Toxic Substances and Disease Registry (ATSDR), a agency at the U.S. Department of Health and Human Services, released its […]

(Beyond Pesticides, May, 7, 2019) Last week, the New York State legislature voted to phase out and eventually ban the use of the neurotoxic insecticide chlorpyrifos. The vote, 44-18 in the state Senate and 94-50 in the Assembly, is still awaiting the Governor’s signature, who is expected to sign the measure. As evidence of harm continues to accumulate, scientists have called for a ban, and a legal case works its way through the courts, pressure is mounting on the U.S. Environmental Protection Agency (EPA) to once and for all remove this harmful pesticide from use. New York’s legislation sets implementation dates that leapfrog a similar law banning chlorpyrifos that passed in Hawai’i last year. Although Hawai’i’s law takes effect beginning in July of this year, the state may provide temporary use permits for the chemical until December 2022. New York also phases in restrictions, first prohibiting aerial applications beginning January 2020, then prohibiting all use except on apple trees starting January 2021. The chemical will be completely banned for use in New York in December 2021. Chlorpyrifos is a highly toxic insecticide that has been linked to damaging and often irreversible health outcomes, particularly for pregnant mothers and their children, […]

(Beyond Pesticides, May 2, 2019) Researchers have documented an increase in food and drinking water residues of neonicotinoids, insecticides linked to breast cancer. Using the Pesticide Data Program (PDP), 1999-2015, of the U.S. Department of Agriculture, the researchers identified near-peak detection frequencies in 2015, after a decline from 2008-2013. Imidacloprid remains the most common neonicotinoid detected across imported commodities, while the neonicotinoids clothianidin, thiamethoxam, acetamiprid, and flonicamid are replacing imidacloprid in domestic production. Authors note that these newer neonicotinoids are potentially more toxic than imidacloprid, raising concerns for understudied human health and environmental impacts. The study, Trends in neonicotinoid pesticide residues in food and water in the United States, 1999–2015, published in the journal Environmental Health, finds the highest detection frequencies for neonicotinoids in drinking water, with 30% of treated drinking water turning out positive for imidacloprid in 2011. Certain fruits and vegetables are also frequently contaminated by neonicotinoids, with detection frequencies ranging from 20% to as high as 57% in the case of imidacloprid on cauliflower. While the study points to specific fruits and vegetables as posing higher risk, the main message reaches beyond individual commodity or individual neonicotinoid results. Authors uncover a systematic increase in detection of neonicotinoid […]

(Beyond Pesticides, May 1, 2019) Evidence of the dangers of glyphosate continues to mount: researchers at Washington State University have identified, in research that exposed pregnant rats to the compound, significant disease and pathology in subsequent generations. The rats were exposed, from day 8 through day 14 of gestation, to half the observable adverse effect level (NOAEL) of glyphosate. Although this study found negligible impacts on the pregnant rats themselves or on their first-generation offspring, dramatic increases in incidence of pathology showed up in the two subsequent generations, including reproductive (prostate and ovarian) and kidney diseases; obesity; and birth anomalies. The study, published in the journal Scientific Reports (an open access, multidisciplinary journal from Nature Research), and conducted by Michael Skinner, Ph.D. and five colleagues, is the first to assess the potential transgenerational impacts of glyphosate in mammals. Its results point to an emerging frontier in assessing the risks of glyphosate and other toxic chemicals, and add to the urgent and growing demand that the use of this particular toxic — and pervasive — pesticide be halted. The research team was interested in looking at possible transgenerational impacts of glyphosate in part because of its ubiquity: it is one of the […]

(Beyond Pesticides, April 26, 2019) Research by the youth participatory action team of the CHAMACOS of the Salinas Evaluating Chemicals in Homes and Agriculture (COSECHA) reveals that teenagers in the Salinas Valley, California are routinely exposed to concerning levels of multiple toxic pesticides, several of them known endocrine disruptors. In an interview with Kion News, COSECHA research director Kimberly Parra remarked that the study is especially important because teenagers are in a stage of rapid reproductive development. As the study authors emphasize, it is their developmental stage that makes teenagers more vulnerable to the effects of endocrine disrupting pesticides, with potentially devastating consequences for lifelong health. The COSECHA study quantifies exposure to 72 pesticides, captured through volatile-trapping silicone wristbands, across 97 teenage girls living in various areas of the Salinas Valley region. Of the 72 pesticides analyzed, authors report that subjects are exposed to as many as 20 and an average of 8 pesticides over one week of routine indoor and outdoor activity. Given the well-documented dangers of pesticide co-exposures, these multiple-exposure findings are particularly concerning. Ranking the highest for prevalence among the studied pesticides is fipronil sulfide, a breakdown product of the insecticide fipronil, detected in 86.6% of the analyzed wristbands. […]
