(Beyond Pesticides, September 17, 2025) A study in Environmental Science & Technology finds additive effects of a synthetic pyrethroid insecticide (cypermethrin) and two fungicides (azoxystrobin and prochloraz) on biological control, biomass of major invertebrate trophic groups (position in food web), and soil ecosystem processes in arable systems (land suitable for growing crops). The study authors further highlight the failure of pesticide regulations to consider elaborate trophic interactions and pesticide mixtures, as well as additive and synergistic effects within their assessments, calling attention to the complexity of real-world exposures and the lack of research to fully understand the implications of chemical use for agricultural and land management purposes. “Arable systems have a high dependence on diverse natural biota to support pest control, soil bioturbation, and nutrient recycling,” the researchers write. These communities rely on a balance of organisms within various trophic levels in order to function and provide vital ecosystem services. Disruptions caused by environmental contaminants, such as pesticides to nontarget organisms, impact entire ecosystems and overall biodiversity. As the authors state, current risk assessments underestimate the real-world risks of petrochemical pesticides and synthetic fertilizers that, despite a wide body of science connecting exposure to deleterious health and environmental effects, are […]

(Beyond Pesticides, September 16, 2025) As reported in the Daily News on August 28, the U.S. Environmental Protection Agency (EPA) announced that it “will hold a public webinar [today], September 16, 2025, at 2:00 PM ET to provide information on the ecological runoff/erosion and spray drift mitigation measures that can be used to protect endangered species from pesticides.” This follows closely behind an earlier announcement of a newly released Pesticide App for Label Mitigations (PALM) mobile tool to assist in implementing these mitigation measures. Despite boasting that the PALM tool is a “one-stop shop” for farmers to use EPA’s mitigation menu, which the agency claims helps to protect nontarget species, environmental critics say that self-directed mitigation without a rigorous reporting and enforcement apparatus fails to meet the level of protection that is necessary under the Endangered Species Act (ESA). As Beyond Pesticides has often reported, mitigation measures are not enforced through recordkeeping, inspections, and certification, and require no accountability from farmers and pesticide applicators. At the same time, EPA assumes compliance with mitigation measures as the basis for meeting statutory standards of reasonable risk from harmful chemicals, despite documented health and environmental harm. As a Daily News article earlier this […]

(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 10, 2025) Published earlier this year, a review of over 1,700 studies in Nature Communications finds pesticides affect a diverse range of nontarget organisms and contribute to global biodiversity loss. The authors* reveal “negative responses of the growth, reproduction, behaviour and other physiological biomarkers within terrestrial and aquatic systems” for nontarget plants, animals, and microorganisms. “To our knowledge, there has been no systematic and overarching synthesis of how different types of pesticides affect the diversity of multiple non-target eukaryotic and prokaryotic organisms across all trophic levels,” the researchers write. They continue, “Furthermore, current syntheses have not considered how the impacts of pesticides differ globally across climatic zones or for major mechanisms of exposure, such as those acting in aquatic or terrestrial environments.” In particular, pesticide regulatory risk assessments analyze a limited range of model species, including rats, zebrafish, clawed frogs, honeybees, and earthworms, among others. As such, they are unlikely to capture the variety of responses to pesticide exposure seen across the diversity of species and communities found in both managed and natural systems,” the authors state. *Authors include Beyond Pesticides 2023 National Forum speaker Dave Goulson—see the Daily News on his keynote address here.

(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, August 28, 2025) The U.S. Environmental Protection Agency (EPA) on August 12, 2025, released a statement, “EPA Announces Action to Protect Endangered Species from Insecticide Methomyl,” in which the agency announced label changes for methomyl, a carbamate insecticide, with mitigation measures that are being criticized as allowing great risks to biodiversity and human health. The label changes, following the National Marine Fisheries Service’s (NMFS) final biological opinion issued on January 1, 2024, actually establish mitigation measures to be determined by applicators using the Bulletins Live! Two website prior to use. EPA claims that this grower determined action will meet the standards of the Endangered Species Act (ESA) by “reduc[ing] runoff and spray drift from treated areas into species’ habitats.” However, the process does not include monitoring and oversight to determine whether the rigorous standards of ESA are being met. The agency says that mitigation tracking is “at the field or farm level,” but it is not required to be submitted to the agency. EPA announced on August 20 that it is holding a 90-minute public webinar on September 16, 2025, at 2:00 PM ET to provide information on the ecological runoff/erosion and spray drift mitigation measures that can […]

(Beyond Pesticides, August 27, 2025) A study published in European Journal of Agronomy finds that “organic farming equals conventional yield under irrigation and enhances seed quality in drought, aiding food security.” For decades, organic advocates have heard from defenders of chemical-intensive agriculture that organic farming is not commercially attainable for widespread adoption and cannot compete on productivity and profitability at a commercial scale. At the same time, chemical manufacturers, chemical-dependent farmers, and their allies greenwash their products (e.g., active ingredients, full formulations, and pesticide-treated seeds) and practices by insisting in regulatory comments, contract science studies, and lobbying campaigns that they are necessary for climate-smart, sustainable, regenerative, and/or integrated pest management agriculture and land management. In this context, the chemical industry alliance is now pushing deregulation, preemption of state and local authority to restrict pesticides, and immunity from lawsuits for the harm caused by their products and practices. An expansive coalition of farmers, farmworkers, conservationists, medical professionals, Indigenous communities, and environmental and public health advocates is fighting back, including Beyond Pesticides. Background and Methodology The researchers tested twelve common bean genotypes of Phaselous vulgaris L., with eight local [Basque Country] landraces (defined by Oxford Language as “a local cultivar [plant] or […]

(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.)

(Beyond Pesticides, July 30, 2025) The definition of per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals” due to their persistence, continues to be debated in regulatory agencies, with many scientists arguing that certain types of chemicals in this vast group are not accurately captured in risk assessments. A wide body of science on the adverse health and environmental effects of PFAS exists, as these synthetic chemicals have become ubiquitous in nature, wildlife, and humans, as demonstrated by biomonitoring studies. Recent research, documented in a literature review in Environmental Science & Technology and additional articles, highlights the importance of a universal, cohesive definition of PFAS that incorporates all fluorinated compounds, including the long carbon chain PFOA (perfluorooactanoic acid) and PFOS (perfluorooctanesulfonic acid) as well as the ultrashort-chain perfluoroalkyl acids (PFAAs). In order to protect health and the environment from the ever-increasing threat of both long and short chain PFAS’ adverse effects, including cancer, endocrine-disrupting effects, and immune system damage, a comprehensive definition of the compounds causing harm is critical to adequate protection and regulatory decisions. The multitude of sources of PFAS and various exposure routes leads to widespread contamination of the environment and organisms. PFAS in agriculture represents a […]

(Beyond Pesticides, July 25, 2025) The scientific literature shows that microplastics (MPs) and pesticides, both ubiquitous throughout the environment, have synergistic effects that threaten aquatic organisms. This means the combined toxicity of the two substances is greater than the sum of two individual exposures. The most recent study to demonstrate this, published in Ecotoxicology, focuses on the impacts of MPs and chlorpyrifos (CPF), a widely used organophosphate insecticide, on cladocerans, a group of microcrustaceans. As Beyond Pesticides has previously reported, microplastics are found in all environments and threaten not only human health but all wildlife in both aquatic and terrestrial ecosystems. The universal distribution of plastics means that they cannot be avoided. Humans and other organisms take up plastics in the form of microparticles and nanoparticles by inhalation, ingestion, and skin contact every day. Microplastics are about the width of a human hair; nanoplastics are much smaller, about twice the width of a DNA strand. Larger pieces of plastic are ground down to these tiny sizes by weathering, temperature, biological processes, and chemical conditions. (See additional Daily News coverage on the health and environmental hazards of plastics here, here, and here.) The authors of the current study, in exposing two […]

(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 10, 2025) A study in People and Nature, with the goal of better understanding the social acceptability of introduced species management (ISM), often labeled “invasive species,” in the U.S., “conducted an online experiment with vignettes describing hypothetical but realistic ISM scenarios, varying targeted taxon (insect or plant), control method (mechanical, chemical and biological), risk severity (low and high) and type of non-target risk (to humans or native species).” This study highlights the debate on defining “invasive” species, as well as the low levels of acceptability by the general public for chemical controls such as pesticides. In addition, as pesticide hazards increase, the authors note that the responses show acceptance for only mechanical controls that incorporate manual removal of species, such as through pulling, cutting, clipping, or mowing. “Surprisingly, there was no significant difference in how respondents ranked risks to people and risks to native species,” the researchers report. This shows the values placed on both human health and biodiversity and “highlight[s] the need for evidence-guided ISM, which includes evidence of harmful impacts of introduced species, as well as risks and benefits of management activities, as one potential way to increase the social acceptability of non-native species management.” […]

(Beyond Pesticides, July 3-4, 2025) On this Independence Day, Beyond Pesticides calls for holistic solutions that, as articulated in the Declaration of Independence, move the nation to ensure “certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.” The founders of the United States were aware of the existential threat of corruption to democratic institutions. Alexander Hamilton, the first Secretary of the Treasury, warned in Federalist No. 68 of The Federalist Papers that the presidency could be overtaken by a despotic figure without adequate safeguards. James Madison, the fourth president of the United States, in Federalist No. 10 speaks to the danger that factions—defined as a group of people or entities “… who are united and actuated by some common impulse of passion, or of interest, adversed to the rights of other citizens, or to the permanent and aggregate interests of the community”—impose on the general public, if not checked by safeguards in the country’s political system. The foundational principles in the Declaration of Independence and the Constitution have been challenged under the current administration and in the U.S. Congress. Communities are facing a fourfold attack on these principles and the centuries-old promise of the nation: […]

(Beyond Pesticides, July 1, 2025) Published in Water Research, a study highlights the various routes for pesticide contamination, with the results identifying the presence of over 80 substances in streams without adjacent agricultural land use. “Our findings underscore the necessity of further investigating the non-agricultural entry pathways of pesticides and biocides to effectively mitigate their impacts on streams in non-agricultural catchments,” the authors state. They continue, “These streams often serve as critical refuge habitats and sources of recolonization, making their protection essential for biodiversity conservation.” In analyzing nonagricultural streams, the researchers find pesticide contamination that, while lower than levels found in streams directly next to agricultural land, can occur through various routes and threatens biodiversity in essential ecosystems. As the authors describe: “Although pesticide concentrations were lower than in agricultural streams, the potential toxicity of pesticides was associated with a significant reduction in sensitive insect populations, as indicated by the SPEARpesticides index. Notably, 40% of the studied streams did not achieve a good status according to the pesticide specific SPEARpesticides indicator.” The SPEARpesticides indicator is used “to identify pesticide effects on the aquatic invertebrate community. It measures the abundance of pesticide-sensitive species (“species at risk”) in relation to the abundance […]

(Beyond Pesticides, June 26, 2025) A review article in Nature Reviews Earth & Environment highlights how the pesticides used in global crop production pose risks to ecosystems and human health through multiple pathways. As the authors note, “Once applied to crops, pesticides are transported through surface and groundwater flows, atmospheric dispersion and wildlife migration.” Residues in food products, such as fruits and vegetables, as well as bioaccumulation within animals that are consumed as food, also threaten consumers around the world, particularly those relying on international trade. The researchers note: “In this Review, we summarize the pathways through which synthetic pesticides transcend boundaries, focusing on the impacts of their use in food production… First, we explain how environmental flows contribute to transporting pesticides to regions far from their original source. Next, we examine the role of international food trade in causing transboundary exposure and impact of pesticide use.” As a result, the study calls for prioritizing biodiversity and human health through sustainable methods while maintaining yield to support the growing population. The use of pesticides in chemical-intensive agriculture has exponentially increased since their first synthesis in the late 1930s. “Globally, pesticides were applied on agricultural land at an average rate of […]

(Beyond Pesticides, June 23, 2025) At the close of National Pollinator week, Beyond Pesticides says in an action that all species—and their ecosystem—are threatened by the failure of the U.S. Environmental Protection Agency (EPA) to perform its statutory duties under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Endangered Species Act (ESA). Under FIFRA, EPA is required to register pesticides only when they pose no “unreasonable risk to man [sic] or the environment, taking into account the economic, social, and environmental costs and benefits.” Under ESA, EPA must, like all federal agencies, “seek to conserve endangered species and threatened species and shall utilize their authorities in furtherance of the purposes” of the ESA—which are “to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved, to provide a program for the conservation of such endangered species and threatened species, and to take such steps as may be appropriate to achieve the purposes of the treaties and conventions” through which “the United States has pledged itself as a sovereign state in the international community to conserve to the extent practicable the various species of fish or wildlife and plants facing extinction.” In this context, Beyond Pesticides […]

Image: Art Page submission from Sara Grantham, “Pollen Song.” (Beyond Pesticides, June 20, 2025) A study in Conservation Genetics, entitled “Organic farming fosters arthropod diversity of specific insect guilds – evidence from metabarcoding,” showcases the negative effect of chemical-intensive, conventional farm management on insect populations when compared to organically managed meadows. The researchers find that the diversity and biomass of flying insects are higher with organic land management by 11% and 75%, respectively. “We report a higher diversity on organic meadows in comparison with conventional ones, all over the diversity of flying insects and not only based solely on a few species-poor groups as in previous studies,” the authors state. They continue: “We found significant richness differences between management types and increased functionality on organic meadows. Our results imply the superiority of organic farming in comparison to conventional farming in the conservation of insect diversity.” The topic of insect biodiversity and the decline of insect populations over the last few decades, also referred to as the insect apocalypse, has been extensively covered by Beyond Pesticides. As previously reported in the Daily News, “Continued Decline in Insect Species Biodiversity with Agricultural Pesticide Use Documented,” insects provide many important services, such as […]

***Featured Art Page submissions for National Pollinator Week, highlighted with the gratitude of Beyond Pesticides: Jesse from Livermore, CA: “Honeybee Pollinating Citrus Blossom”; Yumi from New York, NY: “Birds and the Bees”; Gretchen from Helena, MT: “Butterflies”; Janet from Concord, MA: “Beneath the Big Dipper”; and Trix from Petersburg, NY: “Downy Woodpecker.” (Beyond Pesticides, June 16, 2025) Every year, Beyond Pesticides announces National Pollinator Week to remind eaters of food, gardeners, farmers, communities (including park districts to school districts), civic organizations, responsible corporations, policy makers, and legislators that there are actions that can be taken that are transformative. All the opportunities for action to protect pollinators, and the ecosystems that are critical to their survival, can collectively be transformational in eliminating toxic pesticides that are major contributors to the collapse of biodiversity. This is why Beyond Pesticides starts most discussions and strategic actions for meaningful pollinator and biodiversity protection with the transition to practicing and supporting organic. In launching National Pollinator Week, Beyond Pesticides makes suggestions for individual actions to increase efforts to think and act holistically to protect the environment that supports pollinators. The impact that people have starts with grocery store purchases and the management of gardens, parks, […]

(Beyond Pesticides, June 12, 2025) Thailand-based researchers, in a study published in BMC Veterinary Research, found significant documentation of the occurrence of anticoagulant rodenticide (AR)-induced toxicosis for nontarget organisms in the country. This includes the finding that “all submitted samples of suspected AR exposure in wild animals and exotic pets tested positive for ARs.” These findings signal the pervasive nature in which agrichemical products, including anticoagulant and nonanticoagulant rodenticides, encroach on broader ecosystem health. In an era of federal deregulation and increasing public scrutiny of the role of government in addressing public health, biodiversity, and the climate crisis, advocates continue to call for a wholesale transition to organically managed food and land management systems. Background and Methodology “In this retrospective study, we investigated the occurrence of AR poisoning in animal specimens analy[z]ed at the Department of Veterinary Pharmacology, Faculty of Veterinary Science, Chulalongkorn University (DVPCU), between 2018 and 2023,” say the authors on the primary focus of this study. “This study aims to provide a reference dataset for future research on the epidemiology of AR toxicosis in nontarget species.” The authors declared that there were “no competing interests” in engaging in this research. The anticoagulant rodenticides were detected through two […]

(Beyond Pesticides, June 5, 2025) A study conducted in Pennsylvania and published in Environmental Entomology highlights threats to nontarget organisms from neonicotinoid insecticide exposure. Using species of ground beetles as an example, the study documents sublethal behavioral effects as well as decreased week-long survival. This research fills a notable gap in current research, with the authors explaining, “Predatory soil arthropods are under-represented in insecticide toxicity studies, severely limiting our understanding of how insecticides affect soil-invertebrate communities in agroecosystems.”  The researchers continue, “As a step toward addressing this issue, we conducted novel acute oral, topical, and soil-based toxicity assays on 9 ground beetle species (Coleoptera: Carabidae) in response to the neonicotinoid insecticides clothianidin, thiamethoxam, and imidacloprid.” The nine carabid beetle species, all common to agroecosystems in central Pennsylvania, were exposed to clothianidin, while additional assays with thiamethoxam and imidacloprid were conducted on the two most abundant species. A wide body of science exists that connects neonicotinoid exposure to health effects in a variety of nontarget organisms. Neonicotinoids, a class of neurotoxic insecticides, act as agonists of nicotinic acetylcholine receptors, “persist under field conditions, and are water soluble, enabling them to translocate into plants and provide systemic protection of seedlings,” the […]

(Beyond Pesticides, May 13, 2025) A study in Environmental Pollution examines ecological and health risks in farmland soil with pesticide contamination. “Although agricultural soil pesticide residues have long threatened the environment, a relatively complete system for evaluating their health and ecological risks has not yet been developed,” the authors state. In addressing this research gap, the study finds that “more than ten pesticides were detected in 98.62% of the soil samples, which changed the soil environment” and threatens the health of the soil microbiome. The authors continue, “This study investigated the correlation between pesticide residue risks and soil ecological security and human health, revealed the response characteristics of soil microbial communities under pesticide stress, and identified microbes strongly related to pesticide ecological risks.” Pesticides, as the authors emphasize, “inevitably pollute agricultural soil, affect the ecological environment, and pose a threat to human health.” (See studies here, here, and here.) With this in mind, they assess 50 selected pesticides in 145 soil samples from agricultural land in Zhejiang Province, China and calculate the associated risks to ecosystems and public health. In describing the importance of this research, the authors explain: “Pesticides are prone to leakage and drift in environmental media, turning […]
