(Beyond Pesticides, January 29, 2026) A study of ecotoxicity risk from neonicotinoid insecticides, published in Environmental Chemistry and Ecotoxicology, finds that chemicals in this class of pesticides, particularly dinotefuron, increase the body temperature of Apis mellifera (European honey bee) and subsequently accelerate the translocation (movement) of contaminants into hives by the honey bees. The research indicates that neonicotinoids affect acetylcholine receptors in the nervous system, leading to an “elevation in octopamine titer [neurotransmitter/hormone] and subsequent increase in the body temperature of honeybees,” the authors report. They continue: “Furthermore, we observed a considerable upregulation [of] the expression of a flight gene flightin in honeybees. This gene accelerates the homing behavior of honeybees and facilitates the rapid and frequent transport of neonicotinoid pesticide-contaminated nectar to the hive.” In describing their results, the researchers state: “For the first time, we propose that neonicotinoid pesticides accelerate the homing ability of honeybees by affecting their body temperature, which leads to more neonicotinoid pesticides entering the hive and explains the prevalence of neonicotinoids and at higher concentrations in terms of their effects on the honeybee body temperature that enhances homing.” This accelerated movement of neonicotinoid pesticides into honey bee hives heightens the toxicity risks to honey […]

(Beyond Pesticides, January 28, 2026) A study published last year in Science of The Total Environment reports widespread pesticide contamination collected from beehive monitoring across the European Union (EU). “This study has produced the first EU-wide distribution map of terrestrial pesticide contamination and demonstrates widespread pesticide contamination of EU environments,” the authors write. The study, led by a cohort of citizen-scientists, documents pesticide drift across the European continent. The results found that 188 of the 429 targeted pesticide compounds were detected in noninvasive, in-hive passive samplers (APIStrips) across 27 EU countries between May and August of 2023. This finding emerges at a time when public health and environmental advocates raise concerns about the European Union’s backtracking on commitments to reduce pesticide use by 2030, although the European Commission announced in July 2025 that “the use and risk of chemical pesticides has decreased by 58% by 2023 [from the 2015-2017 reference period], while the use of more hazardous pesticides fell by 27% over the same period.” Results The study results reveal that no landscape is safe from pesticide exposure, despite the European Union having better regulations in place than most other countries/regions. The researchers found: “There was no sample site where […]

(Beyond Pesticides, January 22, 2026) Published in Environmental Research, a review of experimental studies by George Mason University researchers regarding reproductive toxicity of neonicotinoid pesticides (neonics) in rodents finds that all studies “demonstrated negative impacts on male reproductive endpoints in association with neonic exposure, including reduced sperm count, reduced sperm motility, and altered sperm morphology.” These studies highlight how neonics, designed to target insect nervous systems, can affect mammalian systems, representing risks to human health. Criteria for inclusion in the review was restricted to endocrine and/or reproductive outcomes in male rats and mice, leading the authors to analyze 21 studies published between 2005 and 2025. “This narrative review employed a systematic approach and determined that neonics exhibit reproductive toxicity in male rats and mice, particularly impairing testicular function and sperm quality at high exposure levels,” the researchers report. They continue, “Despite species-specific differences, the conserved nature [core mechanism] of reproductive processes across mammals supports the relevance of these findings to human health.” Study Background Neonicotinoids are a class of insecticides that share a common mode of action that affects the central nervous system of insects, resulting in paralysis and death. There is a wide body of science on the effects […]

(Beyond Pesticides, December 19, 2025) While still the exception rather than the norm, a growing movement of Christmas tree farmers across the United States is demonstrating that organically managed systems can also be applied when choosing a tree during this holiday season. Health and environmental advocates across the country are calling for a transition away from toxic pesticide dependency during the holiday season. Beyond Pesticides maintains a webpage, Christmas Trees and Pesticides, and Center for Biological Diversity and Alliance of Nurses for Healthy Environments urged the U.S. Environmental Protection Agency and U.S. Department of Health and Human Services to conduct a “special review of pesticides used on Christmas trees.” The groups sent a letter on December 4, the day the National Christmas Tree was lit at the White House, specifically citing the need to review the pesticides chlorpyrifos, carbaryl, dimethoate, bifenthrin, chlorothalonil, glyphosate, hexazinone, imidacloprid, simazine, and 2,4-D, among others. Christmas is one of the most celebrated holidays in the United States, with Christmas trees grown on Christmas tree farms being brought into homes as part of the celebration. On average, Americans purchase 25 to 30 million Christmas trees annually, according to the National Christmas Tree Association; however, certified organic […]

(Beyond Pesticides, November 20, 2025) Recent scientific literature finds heightened toxicity associated with pesticide metabolites, the transformation/breakdown products of the parent compounds, that threaten the health of the soil, wildlife, and humans. This research stresses the importance of the U.S. Environmental Protection Agency (EPA) evaluating metabolites, which is currently insufficiently included in regulatory processes. In a literature review in Global Change Biology, the researchers point out multiple areas in which regulations fail to address key criteria, including metabolites, saying: “Pesticide risk assessments currently rely on surrogate species and focus primarily on acute lethality metrics, failing to capture the broader impacts on non-target organisms and thus biodiversity. Under the directives of regulatory agencies worldwide, this traditional approach overlooks the complex interactions between multiple stressors, including climate change, land-use shifts, and pesticide transformation products. Pesticide risk assessments must therefore undergo a paradigm shift to account for these complex interactions, which disproportionately affect insect pollinators, other non-target species, and biodiversity at large.” A metabolite is a breakdown product that forms when a pesticide is used in the environment and mixes with air, water, soil, or living organisms. All metabolites fall under the category of transformation products, which is the broader term for any […]

(Beyond Pesticides, November 19, 2025) In the book, Biological Control Systems and Climate Change, published this month, Danilo Russo, PhD—a speaker during the first session of our 42nd National Forum, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature—and other researchers add to the existing literature on the climate change threat to ecosystem services. Dr. Russo’s chapter, entitled “Impact of Climate Change on Bats Involved in Biological Control,” explains one of the lost benefits of ecological balance attributable to the climate crisis. As explained in the book: “In conservation biological control, habitats surrounding and within crops are managed to favour an increase in natural enemy populations while suppressing pest populations. These agroecological systems can be complex, and are affected by climate change.” The ability of climate change to influence the effectiveness of biological control systems is explored, showing the “effects on the large diversity of macro- and microorganisms involved in biocontrol, and the possible increase or decrease in pest outbreaks following changes in characteristics (morphology, physiology, behaviour….), distribution or phenology.” Dr. Russo is a full professor of ecology at the University of Naples Federico II, an international leader in bat research, and coauthor of A Natural History […]

(Beyond Pesticides, October 29, 2025) The latest research on bats and beavers, ecosystem services, and biodiversity adds to a wide body of science on the importance of a balanced ecosystem. In both the Bulletin of the National Research Centre and Journal of Animal Ecology, the researchers highlight the interconnectedness not only between wildlife species but to broader ecosystem functioning and human health implications. Researchers in the Journal article add to the growing body of science connecting an abundance of bat species in areas with established beaver dams, highlighting how interconnected wildlife is. The reporting on this recent research coincides with Beyond Pesticides’ 42nd National Forum, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature, scheduled for today, October 29. As the author of the article in the Bulletin of the National Research Centre, entitled “The complex web between environmental disruption, pesticide use, and human health: lessons from the bat crisis,” states: “The close relationship between environmental balance, biodiversity, and human health has long been a concern of science and public policy. Disruptions in ecosystems often trigger cascading effects that extend far beyond the original ecological imbalance, affecting agricultural practices, food security, and public health.” Bat Declines and […]

(Beyond Pesticides, October 9, 2025) The 42nd National Forum Series, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature—scheduled to begin on October 29, 2025, 1:00-3:30pm (Eastern time, US), will focus on aligning land management with nature in response to current chemical-intensive practices that pose a threat to health (see Pesticide-Induced Diseases Database), biodiversity, and climate. The virtual Forum is free to all participants. ➡️ Register here. The Call to the Forum, states: We are all affected by how land is managed, food is grown, and nature is protected. Different experiences and perspectives may bring us to care about health and the environment and the devastating adverse effects of pesticides and toxic substances. However, ensuring a livable future requires us to cultivate a collective concern about daily decisions on the management of our personal and community spaces, the practices used to grow the food we buy, and the care that we as a society give to complex and fragile interrelationships that sustain the natural world on which we depend.   The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature challenges participants—as concerned families, community residents, purchasers of products, advocates for policy, decision makers, and workers—to think […]

(Beyond Pesticides, October 8, 2025) A study, Pesticides detected in two urban areas have implications for local butterfly conservation, published in partnership with researchers at Xerces Society for Invertebrate Conservation, University of Binghamton (New York), and University of Nevada, reports widespread pesticide residues in the host plants of butterflies located in green spaces in the cities of Sacramento, California, and Albuquerque, New Mexico. Just 22 of the hundreds of collected samples had no detectable residues, with all other samples containing some combination of 47 compounds of the 94 tested pesticides in the plant tissue. Of the 47 compounds, 4 are neonicotinoid insecticides linked to adverse effects for bee and pollinator populations based on previous peer-reviewed research. The fungicide azoxystrobin and the insecticide chlorantraniliprole were detected at lethal/sublethal concentrations, according to the report authors. “Residential landscapes have high conservation potential for butterflies and other invertebrates,” says Aaron Anderson, co-lead author of the report and pesticide program specialist at Xerces Society for Invertebrate Conservation. He continues: “But, these findings show how pervasive pesticide contamination can be in towns and cities, and underscore that protecting wildlife in these areas includes addressing pesticides.” The report’s results underscore the pervasiveness of pesticide drift and dispel the myth […]

(Beyond Pesticides, September 24, 2025) A novel study of chronic toxicity of the neonicotinoid insecticide thiamethoxam to honey bees (Apis mellifera), published in Insects, finds sublethal effects that threaten the survival of bee larvae and the health of bee colonies. “We evaluated the effects of thiamethoxam on the entire larval development cycle of reproductive bees and conducted a comparative analysis, demonstrating that thiamethoxam significantly alters ecdysone [a hormone that controls molting in insects] and juvenile hormone titers [hormones for insect growth] in both queen and drone larvae, impairing metamorphosis and reproductive development,” the authors state. Risk assessments and scientific literature focus primarily on honey bee workers, rarely including how pesticides can impact queen and drone bees that are necessary for stable colonies. In focusing on this data gap, the researchers reveal that the survival rate of bee larvae decreases gradually with increasing doses of thiamethoxam, adding to the wide body of science on pesticide-related threats to honey bee health. (See Beyond Pesticides’ What the Science Shows on Biodiversity page for more information, as well as Daily News coverage on risk assessments here, here, and here.) Honey bees provide crucial ecosystem services as pollinating insects and play a vital role in […]

(Beyond Pesticides, September 11, 2025) A study published in Agriculture, Ecosystems & Environment finds organic rice paddies in the Mediterranean region have greater ecosystem biodiversity, including increased presence of aquatic microorganisms and insects, than their chemical-intensive counterparts. While not a “cradle-to-grave” or holistic analysis of organic vs. chemical-intensive agriculture (see a similar example in previous Daily News here), the authors note that there is an increase in greenhouse gas emissions (GHGe) associated with compost use, which replaces synthetic fertilizers. Typically, compost builds biological life in the soil and contributes to a drawing down (or sequestering) of atmospheric carbon. As EPA notes, “[C]omposting lowers greenhouse gases by improving carbon sequestration in the soil and by preventing methane emissions through aerobic decomposition, as methane-producing microbes are not active in the presence of oxygen.” The transition to organically produced rice in the U.S. has come with challenges. One includes thorny debates over the inclusion of copper sulfate on the National List of Allowed and Prohibited Substances, which establishes materials permitted for use in certified organic production under the Organic Foods Production Act (OFPA). Under the law, USDA restricts copper sulfate in organic farming as follows: “For use as tadpole shrimp control in aquatic […]

(Beyond Pesticides, September 8, 2025) Beyond Pesticides today called on Congress to require the U.S. Environmental Protection Agency (EPA) to incorporate real world science into its evaluation of pesticide safety calculations by recognizing that daily exposure involves multiple chemicals and synergistic interactions— a magnified effect greater than the individual chemical effects added together. The organization cites numerous scientific studies that call public attention to this issue; that a realistic assessment of the human and environmental harm potentially caused by pesticides cannot be evaluated based on single-chemical, single-species tests. Given the numerous complexities associated with this type of assessment, the group points to organic land management in agriculture and residential areas as a more cost-effective approach, sending this message to Congress: EPA must consider the effects of pesticides in the context in which they are used and with reference to the organic alternative. A recent study, covered by Beyond Pesticides in its Daily News, found that the presence of Varroa mites in combination with the neonicotinoid insecticide imidacloprid increases the risk of bee mortality and disrupts the larval gut microbiome. The study found synergy (a greater combined effect) between Varroa destructor, a parasitic mite that attacks and feeds on honey bees, and imidacloprid. The findings were published last […]

(Beyond Pesticides, September 4, 2025) A review of agricultural neonicotinoid insecticide regulations, published in Pest Management Science, evaluates the varied approaches being taken for bans and exemption-based restrictions in the European Union (EU), Canada, and the United States (U.S.). Despite an ever-growing and overwhelming body of science linking neonicotinoids (neonics) to adverse effects on pollinators and other nontarget species, the regulations fall short in protecting the environment and wildlife. The review, with the history and current status of neonics, lends further support for a full transition to organic agriculture and land management that removes neonicotinoid exposure routes and subsequent health threats. With the application of this widely used class of neurotoxic system insecticides increasing, so too has the concern over the long-term chronic effects on pollinators and other species from exposure. This concern, backed by scientific literature, has “led to increased governmental regulations since the mid-2010s, particularly in agricultural settings,” state the authors from Iowa State University and Washington State University. They continue, “These regulations have varied in terms of approach, geography, and timeline, starting with a ban implemented by the European Union (EU) and evolving into exemption-based regulations across two Canadian provinces and five U.S. states as of this […]

(Beyond Pesticides, September 3, 2025) A study in Environmental Entomology shows that habitat and open space near agricultural fields become a killing field of pesticides, threatening biodiversity due to contamination from toxic drift. The study detected 42 pesticides, including several neonicotinoids, which are among the most lethal threats to pollinators. The research reveals the complexity of pesticide flow through the environment and the inadequacy of current methods of protecting nontarget organisms, including honey bees, bumblebees, and hundreds of other species of native bees worldwide. Their catastrophic declines is tied to pesticides in large part and highlights the inadequacy of current pesticide reduction strategies, such as integrated pest management (IPM) and now other loosely defined concepts like “regenerative,” in an attempt to protect the environment and nontarget organisms in chemical-dependent land management and agriculture. (See What the Science Shows on Biodiversity.) The researchers on the study, from the U.S. Department of Agriculture, Cornell University and Michigan State University, put silicone bands on fence posts in open areas adjacent to highbush blueberry fields on 15 farms in western Michigan. Silicone takes up chemicals in the atmosphere which can then be extracted and analyzed. The fence posts were placed at seven intervals ranging […]

(Beyond Pesticides, August 21, 2025) The presence of Varroa mites in combination with the neonicotinoid insecticide imidacloprid increases the risk of bee mortality and disrupts the larval gut microbiome, according to a study of the synergy (a greater combined effect) between Varroa destructor, a parasitic mite that attacks and feeds on honey bees, and imidacloprid. The study in Pesticide Biochemistry and Physiology adds to the growing body of science on the severely declining bee population by investigating the toxic effects of both the parasites and pesticide stressors in honey bees (Apis mellifera). “Given that V. destructor may increase bees’ sensitivity to imidacloprid by compromising their physiological health and immunity, this study systematically assesses the effects of V. destructor infestation and imidacloprid exposure on honey bee survival, detoxification enzyme activity, and gut microbiota,” the authors explain. The intestinal tract and gut microbiome are crucial for digestion, metabolism, nutrient absorption, immune regulation, and pathogen defense. Within honey bees, the gut microbiome is “highly susceptible to external environmental stressors, such as pesticide exposure and parasitic infections [and] these disturbances can lead to microbial imbalances, ultimately affecting bee health.” (See studies here and here.) Previous research earlier this year, captured in Daily News Variability […]

(Beyond Pesticides, August 20, 2025) As a part of a nationwide push to stop the use of petrochemical pesticides and fertilizers, Beyond Pesticides, in partnership with the City of Excelsior, Minnesota, and Osborne Organics, announced the transition of city park land sites to organic land management. Under its program, Parks for a Sustainable Future, Beyond Pesticides underwrites the development of organic transition plans and staff training on holistic practices. The goal of the program is to advance practical, resilient, cost-effective management techniques that confront urgent threats to public health, biodiversity, and climate that are exacerbated by toxic pesticide and fertilizer use. See the link to our press release here.  Excelsior City Councilmember Jennifer Caron said, “Excelsior has embarked on an exciting first step in organically managing our public parks and minimizing runoff into the lake.” Ms. Caron added: “By participating in the Parks for a Sustainable Future grant program with Beyond Pesticides, the city is learning how to eliminate herbicides, insecticides, and other pesticides on sites in the Commons, including the Ballfield and Great Lawn. The result will be a healthier Commons, particularly in areas heavily used by people, pets, and pollinators alike.”   Kevin Quinn, parks and natural resources manager for Excelsior, said: “Working with […]

(Beyond Pesticides, August 15, 2025) In analyzing the data present in an article in Data in Brief, concerning levels of pesticide biomarkers are present in the urine of adolescents and young adults that are linked to numerous health implications. The biomonitoring data, collected at two time points from participants in a longitudinal cohort study in the agricultural county of Pedro Moncayo, Ecuador, encompasses a total of 23 compounds used as herbicides, insecticides, and fungicides and their associated metabolites (breakdown products), which include organophosphates, pyrethroids, and neonicotinoids. The results highlight the disproportionate risks to a Latin American population that occur as a result of living in areas with heavy chemical-intensive agriculture. “This article presents urinary pesticide metabolite concentrations for 665 participants in the ‘Study of Secondary Exposure to Pesticides among Children, Adolescents, and Adults’ (ESPINA), which were collected during two follow-up assessments,” the authors describe. The first sampling period from July to October 2016, referred to as Follow-up Year [FUY]-8b, includes 529 of the participants, while the second sampling period from July to September 2022 (FUY-14a) includes 505 of the participants. All participants are within the agricultural community of Pedro Moncayo. As the authors note, “The ESPINA study aimed to include […]

(Beyond Pesticides, August 8, 2025) In a study published in Environmental Pollution, researchers have detected eighty pesticides (35 insecticides, 29 fungicides, and 11 herbicides, and metabolites) in the ambient air of a rural region of Spain (Valencia) between 2007 and 2024. Despite these dramatic findings, the authors conclude that there is “no [observable] cancer risk,” “no inhalation risk for adults,” and only one pesticide concentration (the insecticide chlorpyrifos) showing “a potential risk to toddlers.” However, the authors did not conduct an aggregate risk assessment that would typically consider all routes of exposure to the individual pesticides detected, including through water, food, and landscapes. Not considered by the authors are the potential effects of pesticide mixtures and full pesticide product formulations (with all potentially toxic ingredients), also a deficiency in the U.S. Environmental Protection Agency (EPA) registration of pesticides under federal law. Of concern, as well, are other contaminants in pesticide products, including but not limited to per- and polyfluoroalkyl substances (PFAS), heavy metals, plastics (including microplastics), which contribute to chronic diseases and health risks, and adverse effects to ecosystem stability exacerbated by the climate crisis. Background and Methodology “This work aims to conduct a further study on the situation of […]

(Beyond Pesticides, July 31, 2025) A study published in Environmental Advances finds that hundreds of honeybee hives across central and northern Italy are contaminated with various pesticides and their metabolites, including glyphosate and fosetyl.  “There was no significant difference in glyphosate presence between dead/dying and live bees, suggesting chronic exposure rather than acute toxicity. However, higher pesticide concentrations in dead/dying bees indicate potential sublethal effects contributing to colony distress,” according to the authors. This peer-reviewed study builds on the mounting evidence outlined in the literature connecting pesticide residues to nontarget harm to pollinators and other insects and animals that are critical to biodiversity. Background and Methodology “The primary objectives of this study were to develop and validate a reliable, sensitive method for analyzing polar pesticides [highly soluble in water] in honeybees and to investigate polar pesticides residue levels in honeybees across northern and central Italy,” say the researchers of this study, who conduct research at the Experimental Zooprophylactic Institute of Lombardy and Emilia Romagna “Bruno Ubertini”, Experimental Zooprophylactic Institute of Umbria and Marche “Togo Rosati”, and Experimental Zooprophylactic Institute of Lazio and Tuscany “M. Aleandri.” 314 honeybee samples were gathered voluntarily from local beekeepers in six regions of northern and […]

(Beyond Pesticides, July 18, 2025) A study in Royal Society Open Science shows intraspecific differences (between individuals of a species) in wild bumblebees (Bombus vosnesenskii) exposed to an herbicide (glyphosate), a fungicide (tebuconazole), and an insecticide (imidacloprid), with gut microbiome health as a factor. “Wild pollinator declines are increasingly linked to pesticide exposure, yet it is unclear how intraspecific differences contribute to observed variation in sensitivity, and the role gut microbes play in the sensitivity of wild bees is largely unexplored,” the authors explain. “Here, we investigate site-level differences in survival and microbiome structure of a wild bumble bee exposed to multiple pesticides, both individually and in combination.” In collecting 175 individuals of this wild, foraging species from an alpine meadow, a valley lake shoreline, and a suburban park and exposing them to a diet with individual pesticides and mixtures, the researchers assess the varying lethal and sublethal effects that can occur with pesticide exposure. Between the three sites, the survival differences “emphasize the importance of considering population of origin when studying pesticide toxicity of wild bees” and highlight how pesticide sensitivity not only varies between species but within individuals of the same species with site-specific impacts. (See previous Daily […]

(Beyond Pesticides, July 17, 2025) The widespread use of pesticides year-after-year, decade-after-decade, has been found to lead to unintended consequences not only for public health but also for broader ecosystem stability and biodiversity. These impacts include potential nontarget harm through adverse developmental and reproductive effects on the vinegar fly, Drosophila melanogaster, the subject of a peer-reviewed study in Royal Society Open Science. The authors, who studied the organochlorine fungicide chlorothalonil, conclude, “Chlorothalonil exposure decreases larval survival, extends developmental duration and reduces fecundity.” “Even at the lowest tested concentration, chlorothalonil exposure resulted in reduced body weight, ovariole count and egg production compared with non-exposed individuals,” the researchers find. This study builds upon years of scientific research findings and critiques of existing federal pesticide law, as well as the U.S. Environmental Protection Agency’s (EPA) failure to fully assess the adverse impacts on biodiversity and ecosystem stability during the pesticide registration review process. Methodology and Background The goal of this study is to evaluate the health impacts on a nontarget insect species (Drosophila melanogaster) from chronic exposure to chlorothalonil. This specific fungicide was chosen for various reasons, including its wide use across cereals, vegetables, and fruits; evidence linked to adverse health effects on […]

(Beyond Pesticides, July 16, 2025) A study following a mass mortality event of approximately 200 monarch butterflies (Danaus plexippus plexippus) in Pacific Grove, California, highlights the role of pesticides, synthetic pyrethroids in particular, in causing lethal and sublethal effects to nontarget organisms. The research, published in Environmental Toxicology and Chemistry, detects residues of 15 pesticides and associated metabolites in the bodies of 10 deceased butterflies collected from the January 2024 event that occurred near an overwintering site frequented by monarchs. “On average, each monarch butterfly contained 7 pesticides,” the authors report. They continue, “Notably, three pyrethroid insecticides—bifenthrin, cypermethrin, and permethrin—were consistently detected at or near each chemical’s lethal dose (LD50).” LC50, or Lethal Concentration 50, values represent the concentrations of chemicals lethal to 50% of a test population. To assess pesticide residues within ten of the deceased butterflies, the researchers use liquid and gas chromatography with tandem mass spectrometry (LC-MS/MS and GC-MS/MS) and find “a total of 15 pesticides and associated metabolites in the butterflies, including 8 insecticides (plus 1 associated metabolite), 2 herbicides (plus 2 associated metabolites), and 2 fungicides.” The study “present[s] evidence that the mortality incident at the Pacific Grove Monarch overwintering site was likely caused by […]

(Beyond Pesticides, July 15, 2025) A study published in Environmental Science and Technology finds that there are 47 current-use pesticides—products with active ingredients that are currently registered with U.S. Environmental Protection Agency (EPA) —detected in samples of indoor dust, drinking water, and urine from households in Indiana. This study builds on existing scientific literature documenting the public health threat of nonoccupational, indoor pesticide exposure. (See previous Daily News here, here, and here.) The study is a reminder that pesticides move into the indoor environment through the air, and on clothing, making exposure more widespread than the assumptions used in regulatory reviews. Background and Methodology “In this study, we collected matched samples of indoor dust, drinking water, and urine from 81 households in Indiana, United States, and analyzed these samples for 82 CUPs [current use pesticides], including 48 insecticides, 25 herbicides, and 9 fungicides,” say the authors. They continue: “Of these, 47 CUPs were identified across samples of indoor dust, drinking water, and urine with median total CUP (∑CUP) concentrations of 18 300 ng/g, 101 ng/L, and 2.93 ng/mL, respectively.” The herbicides (13) detected include 2,4-D (2,4-dichlorophenoxyacetic acid), Alachlor, Atrazine, CIAT (Desethyl-atrazine), Diuron, Metolachlor, Metolachlor OA (Oxanilic acid), OIAT (2-Hydroxy-4-isopropylamino-6-amino-s-triazine), OIET […]
