(Beyond Pesticides, December 12, 2025) A study concluding that the weed killer glyphosate did not cause cancer was retracted last week after it was revealed in lawsuit documents that the authors did not disclose their relationship with Monsanto/Bayer. The editor-and-chief, Martin van den Berg, PhD of Regulatory Toxicology and Pharmacology, which published the article 25 years ago, wrote in the journal, “Concerns were raised regarding the authorship of this paper, validity of the research findings in the context of misrepresentation of the contributions by the authors and the study sponsor and potential conflicts of interest of the authors.”  The study, titled “Safety Evaluation and Risk Assessment of the Herbicide Roundup and Its Active Ingredient, Glyphosate, for Humans” and coauthored by three researchers in New York, The Netherlands, and Canada, was referred to as a “Landmark glyphosate safety study” in a recent article by U.S. Right to Know.   While this retraction not only sheds light on Monsanto’s influence through ghostwriting, it adds to the wide body of evidence regarding the regulatory deficiencies currently in place. The revelation is a reminder of related incidents in which Monsanto (Bayer) and other companies have wielded excessive influence at the U.S. Environmental Protection Agency (EPA), undermining the integrity of the science needed to inform the regulatory decisions that safeguard health and the environment. (See Daily News Corruption Problems Persist at EPA.)  EPA Deficiencies  In addition to the initial registration process, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires that EPA conduct a registration review of all pesticide […]

(Beyond Pesticides, December 11, 2025) In an amicus brief published on December 1, 2025, the Office of the Solicitor General (SG) and the White House are calling on the Supreme Court of the United States (SCOTUS) to grant certiorari on Bayer’s petition to shield chemical companies that fail to warn people about the potential hazards of their pesticide products. The U.S. Solicitor General D. John Sauer (former Solicitor General of Missouri, home to Bayer-Monsanto’s U.S. headquarters), in siding with the Germany-based, multinational pesticide corporation, calls for SCOTUS to take on the case, which could lead to a prohibition on state-level failure-to-warn claims based on the arguments laid out in the amicus brief. This move sets the stage for SCOTUS to undermine the main legal argument used to hold pesticide corporations accountable for their harmful products, sending Bayer’s stock price to skyrocket 12 percentage points between December 2 and December 3 after the decision was made public. As of May 2025, Bayer has already paid at least 10 billion dollars in jury verdicts and settlements to cancer victims who have attributed their diagnoses to the use of Bayer/Monsanto’s glyphosate-based Roundup weed killer products, according to Lawsuit Information Center. Two previous petitions […]

(Beyond Pesticides, December 10, 2025) On November 21, 2025, the International Agency for Research on Cancer (IARC), a branch of the World Health Organization (WHO), designated the endocrine-disrupting herbicide atrazine (as well as the herbicide alachlor) as “probably carcinogenic to humans.” Manufactured by the multinational, China-based pesticide corporation Syngenta, atrazine has been linked to various adverse health effects and runoff into waterways across the continental United States for years. Tyrone Hayes, PhD, researcher and professor of Integrative Biology at the University of California, Berkeley, who studies the endocrine-disrupting properties of atrazine and other chemicals, has said that atrazine induces cancer by turning on the enzyme aromatase. Dr. Hayes told conferees of Beyond Pesticides’ 31st National Pesticide Forum that: “[W]hat is concerning about aromatase expression and estrogen in mammals is breast cancer and prostate cancer. With regard to prostate cancer, there is an 8.4-fold increase in prostate cancer in men who work in atrazine factories and bag atrazine. There is at least one correlational study, which I didn’t publish, that shows women whose well water is contaminated with atrazine are more likely to develop breast cancer than women who live in the same community, but don’t drink the well water. (Kettles, […]

(Beyond Pesticides, December 9, 2025) In the Journal of Environmental Quality, researchers at the U.S. Department of Agriculture (USDA) report that a 4-year organically managed corn-soybean-oat system reduces nitrogen (N) loads by 50 percent with corn and soybean yields “equivalent to or higher than conventional [chemical-intensive] in most years.” The findings from a 7-year study comparing nitrate loss in organic and chemical-intensive management found that organically managed perennial pasture reduced nitrogen loads significantly. The study, which focused on nitrate pollution in agriculture that harms biodiversity, threatens waterways, drinking water, and public health, and releases nitrous oxide (an extremely potent greenhouse gas), was conducted at USDA’s National Laboratory for Agriculture and the Environment. Organic and regenerative organic farmers and businesses posit that if commodity crops can be grown in organically managed systems with competitive yields, then this supports their argument for alternative systems not only feasible but economically sustainable and responsible. Background and Methodology The researchers note that, in the eastern and U.S. Midwest, “subsurface tile drainage” (the practice of manually draining fields below the surface soil to assist fields that are otherwise challenging to drain due to wet areas/highly compacted soils) has exacerbated nitrogen and nutrient runoff, ultimately leading to diminished soil health. […]

(Beyond Pesticides, December 5, 2025) A study published this month in Environmental Pollution analyzes the role of neonicotinoid insecticide exposure on bird populations, finding a significant negative effect of imidacloprid use on insectivorous bird abundance. In comparing the effects of the insecticide imidacloprid on bird abundance in France before and after the 2018 ban, the researchers show a weak recovery of bird populations after 2018. The persistent nature of imidacloprid, however, as well as the continued use of other petrochemical pesticides that have adverse effects on bird species, continues to impact populations of all types of birds and other wildlife, leading to cascading impacts on biodiversity.    “Our study shows that imidacloprid is a major covariate of the abundance of birds, in addition to other pesticides that are also negatively related to bird populations, and that these effects are not uniform across species,” the authors report. They continue in saying that the relationship between neonicotinoids and bird abundance varied across bird diets, as “the abundance of insectivorous birds was consistently lower under increasing pesticide use, in particular imidacloprid.” Background As shared in the study and on Beyond Pesticides’ Birds page, bird species can be exposed to pesticides directly through ingestion […]

(Beyond Pesticides, December 4, 2025) In a news release last week on November 26, 2025, the U.S. Environmental Protection Agency (EPA) “issued a comprehensive fact-check addressing dangerous misinformation circulating about EPA’s recent pesticide approvals” that, according to health and environmental advocates, continues to deceive the public about the true risks for health and the environment from petrochemical pesticides including, but not limited to, per- and polyfluoroalkyl substances (PFAS). Also published on November 26, coverage titled The EPA Is Embracing PFAS Pesticides. These Are The Health Risks in Time further highlights EPA’s deficiencies and the threats of PFAS, which Beyond Pesticides has extensively covered. (See here and here.)  The controversy erupted as a result of EPA’s latest proposal to allow a new fluorinated pesticide to the list of four other similar compounds now widely available for use in homes and gardens, buildings, and agriculture. The newest pesticide proposed for EPA registration, epyrifenacil (agricultural weed killer), joins cyclobutrifluram (soil fungicide/nematicide), isocycloseram (household and agricultural insecticide), diflufenican (lawn and agricultural weed killer), and trifludimoxazin (agricultural weed killer), making a total of five PFAS pesticide proposals this year that have been associated with national and worldwide contamination of food, land, and water. Two of these, cyclobutrifluram and isocycloseram, have been approved. “Instead of constraining the use of fluorinated pesticides—persistent and highly toxic […]

(Beyond Pesticides, December 2, 2025) Recently published in Reproductive Toxicology, researchers in Denmark and Iceland investigate the impacts of pesticides on sex hormones, finding that “prenatal exposure to [the insecticide] chlorpyrifos and [weed killer] 2,4-D may affect the reproductive hormones in girls, but not boys, during minipuberty, which may have long-term implications.” Based on their analysis of urinary maternal concentrations of the pesticides and their metabolites and hormone levels in infants, the authors report, “This study examined the association between maternal pesticide exposure and pituitary, gonadal, and adrenal hormones in offspring during infancy.” The sex-specific findings highlight a public health concern with potentially long-lasting transgenerational effects. “We recruited pregnant women from 2010 to 2012 in the Odense Child Cohort, including 489 mother-child pairs,” the authors state. They continue: “Maternal urinary concentrations of the generic pyrethroid metabolite 3-phenoxybenzoic acid (3-PBA), the chlorpyrifos metabolite 3,5,6-trichloro-2-pyridinol (TCPY), and the herbicide 2,4-D were measured at gestational week 28. Serum concentrations of luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone (T), estrone (E1), estradiol (E2), 17-hydroxyprogesterone (17-OHP), Androstenedione (Adione), and Dehydroepiandrosterone sulfate (DHEAS) were assessed in infancy.” The results of the analyses show that in girls, higher maternal urinary TCPY and 2,4-D concentrations are significantly […]

(Beyond Pesticides, November 26-30, 2025) The Beyond Pesticides team and board would like to thank those working in communities across the country and actively working to protect the health of our soil, air, water, and all life. In the spirit of uplifting the intersection of traditional ecological knowledge and science, we would like to share with you some excerpts from Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge and the Teachings of Plants—a collection of essays written by Robin Wall Kimmerer, PhD, founder and director of the Center for Native Peoples and the Environment, professor of environmental biology at the State University of New York (SUNY) College of Environmental Science and Forestry (ESF) in Syracuse, New York, mother, and enrolled member of the Citizen Potawatomi Nation.

(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 17, 2025) Beyond Pesticides ramped up its campaign to transition parks, playing fields, and schoolyards to organic land management after the release of a study showing synergistic effects of glyphosate (Roundup) and urea fertilizers on earthworms and soil health. The organization’s network is asking Mayors nationwide to lead the transition, pointing to the inadequacy of the current system of regulating pesticides based on risk assessments of individual chemicals or individual chemical families. Chemicals interact, causing increased impacts on human, ecological health, and biodiversity. Moreover, humans, other species, and the biosphere rarely experience exposure to single chemicals or chemical families; exposure to multiple chemicals is the rule, not the exception.   Synergistic effects associated with the use of the weedkiller glyphosate have been implicated in several studies showing magnified adverse impact in soil organisms and in mixture with other chemicals:  The extensive use of glyphosate is linked to effects on nontarget soil organisms, with the risks to soil ecosystems widely studied. (See here, here, here, here, and here.)   One study shows that frequent application in tropical systems of glyphosate “reduced soil macroarthropod richness by 21% and altered community composition.   “A recent global risk assessment of glyphosate further estimated that 67−93% of soils pose high risks to Collembola [springtails] and 43−67% pose medium to high risks to […]

(Beyond Pesticides, November 13, 2025) A study in Environmental Science & Technology shows that maternal exposure to organophosphate (OP) and pyrethroid insecticides adversely affects newborn health. Through amino acid and acylcarnitine metabolomics (the study of small molecules known as metabolites) with over 400 mother-infant pairs, this research analyzes metabolic pathways linking pesticide exposure to negative birth outcomes. “To our knowledge, this study is the first to reveal the effect of OP and pyrethroid insecticide exposure on neonatal metabolic signatures, which may elucidate a key role of metabolites in insecticide exposure and birth outcomes,” the authors state. In collecting maternal urine samples in the first and third trimesters, as well as neonatal blood samples after birth, OP and pyrethroid metabolites and metabolomic biomarkers are assessed. Notably, the authors report: “Results indicated that third-trimester maternal urinary levels of 3- phenoxybenzoic acid (3-PBA) and diethyl dithiophosphate (DEDTP) were negatively associated with birth weight. Specifically, a one-unit increase in their ln-transformed [natural logarithm form] concentrations was associated with a 1.508% decrease in birth weight for 3-PBA and a 1.366% decrease for DEDTP.” Additionally, the analyses show that OP and pyrethroid exposure is associated with “disrupted neonatal amino acids and acylcarnitine profiles, with patterns varying […]

(Beyond Pesticides, November 12, 2025) A ballot initiative to repeal a local ordinance in Maine that bans most uses of lawn chemicals was rejected by the voters last week by a 10-point margin. The voters of Falmouth, Maine, 55% to 45%, upheld an updated ordinance that was passed by the town council in February 2025 to protect the community’s health and the coastal environment from petrochemical pesticides and fertilizers, sending a strong message that ecological land management in conformance with organic standards is the responsible path, given pesticide-related health threats, biodiversity decline, and the climate crisis. The ordinance being challenged by the ballot initiative updated a 2020 rule with more stringent criteria and restrictions and the goal of ensuring a holistic approach to land management. Maine has become the bellwether nationwide for communities seeking to eliminate the use of petrochemical pesticides and fertilizers on public and private property, including parks, playing fields, open spaces, and yards. When applied, pesticides move off the target site through drift, volatilization, runoff, and leaching, creating community-wide poisoning and contamination. However, unlike Maine and five other states, most state laws preempt local jurisdictions from restricting pesticides. These states have adopted preemption language at the behest […]

(Beyond Pesticides, November 11, 2025) A study published in Cardiovascular Toxicology (July 2025) finds significant associations between Gulf War deployment-related toxic chemical exposure hazards and various adverse health outcomes, including heightened risk of atherosclerotic cardiovascular diseases (ASCVDs), such as “heart attack, coronary heart disease, stroke, transient ischemic attack, and peripheral vascular disease.” While there were no significant associations found directly between pesticide products and these adverse health effects, researchers attribute this to limited sample sizes and wide confidence intervals as part of the study methodology. Further research is necessary to build on this study, given the preponderance of scientific evidence linking pesticide exposure to heightened health risks to the cardiovascular system. On the issue of statistical significance, the authors state the following: “There may be difficulty [for survey respondents] remembering the[ir] military exposure history since the survey was completed nearly 25 years after the Gulf War.” While it is difficult to pinpoint pesticide exposure as a cause of illness among the toxic mixtures to which service members are exposed, there has been recognition by the Veterans Administration (VA) of diseases that are directly related to military service. Beyond Pesticides previously reported that the VA has established 20 burn pit and […]

(Beyond Pesticides, November 7, 2025) There is little dispute that modern industrial culture has produced a constellation of related chronic conditions contributing powerfully to human disease. In recent decades, attention has begun to focus on the developmental origins of health and disease—prenatal exposures to pesticides, for example, that contribute to diseases in adulthood, such as cardiovascular and metabolic problems, along with the combination, known as cardiometabolic syndrome. Cardiometabolic disorders include obesity, hypertension, cholesterol imbalances, and insulin resistance. The usual suspects blamed for the syndrome are poor diet, physical inactivity, and genetic predisposition. These are all well-established risk factors, but they fail to fully account for the sharp rise in cardiometabolic syndrome globally. Obesity prevalence has doubled and diabetes quadrupled over the last 40 years, according to the Non-Communicable Diseases (NCD) Risk Factor Collaboration. In a study on early life exposure to a pesticide mixture, researchers analyze sex differences in cardiometabolic outcomes from prenatal and early life. The study was conducted by an international team of scientists led by Ana M. Mora, M.D., of the Center for Environmental Research and Community Health at the University of California, Berkeley, using data from the Center for the Health Assessment of Mothers and Children of […]

(Beyond Pesticides, November 5, 2025) Environmental and public health advocates, farmers, and business leaders are raising a glass to the expansion of organic hop production, which aims to boost the viability and growth of organic-certified beer products in the UK. A 2024 report by UK-based Organic Research Centre, in partnership with farmers, follows three years of field trials to assess the suitability of various hop varieties in organically managed systems. At a time when organic hops production in the UK has dropped significantly due to varieties that are vulnerable to downy mildew and hop powdery mildew, the report offers a blueprint for additional on-farm, applied research in the United States, including from groups such as the Organic Farming Research Foundation’s (OFRF) Farmer-Led Trials Program. The report cites promising results for new hop varieties. The continuous use of pesticides not only contributes to biodiversity collapse, public health deterioration, and the climate crisis, but also to the ability to enjoy a beer without fear of exposure to toxic chemicals, including evidence of glyphosate residues found in popular beer and wine brands. (See Daily News here and here.) Background and Methodology The authors of this report reflect on their years-long field trials and […]

(Beyond Pesticides, October 31, 2025) A review in Lancet Neurology provides a clear snapshot of the state of scientific understanding of Parkinson’s disease and how medicine and policy could be improved by shifting focus to the primary causes of the disease, namely environmental toxicants, and to emphasize prevention rather than devoting resources only to treatments and a cure. The study, led by Ray Dorsey, M.D. of the Atria Research and Global Health Institute and the University of Rochester Medical Center, focuses on three classes of environmental toxicants: pesticides, dry cleaning and degreasing chemicals, and air pollution. Because these are pollutants introduced by humans, the authors say, they should be controllable, and “Parkinson’s disease could be thus largely preventable.” According to the review, in the last five years, new evidence has accumulated about three types of pesticides of particular concern. They are not all insecticides, which is the pesticide category most associated with neurological damage. Paraquat is a herbicide used on corn, soybeans, and cotton. Rotenone is used to kill rats and insects. Organochlorine insecticides comprise the third class. The review notes that there are many other pesticides that are neurotoxic and may have common mechanisms of action leading to Parkinson’s and […]

(Beyond Pesticides, October 29, 2025) A study published in Environment International evaluates residues of individual and mixtures of endocrine-disrupting chemicals (EDCs), including pesticides, and finds an association between exposure and hyperactive behavior in children. The researchers evaluated urine samples from over 800 preschoolers, identifying and statistically analyzing concentrations of 22 EDCs, and finding that nine of these chemicals are significantly associated with hyperactivity trajectories and EDC mixtures are positively associated with hyperactive behavior, noting the strongest association in girls.  “The current study indicates the adverse health effects of exposure to mixtures of EDCs among preschoolers, and suggests gender specificity in these effects,” the researchers state. They continue, “This highlights the importance of focusing on multi-pollutant exposure in early childhood.”  Study Importance  “Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children, which has become one of the main factors leading to the burden of disease in children and adolescents worldwide.” The authors continue: “Its core symptoms are high levels of inattention and/or hyperactivity/impulsivity during the preschool period. A meta-analysis showed that the overall prevalence of ADHD in children in China over the past 15 years was as high as 6.2%, and has been increasing over recent years.”  In comparison, according […]

(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 24, 2025) A literature review published in Science of the Total Environment reports numerous peer-reviewed studies associating prenatal and childhood pesticide exposure to measurable alterations to children’s immune systems, including indicators of immunosuppression and increases in pro-inflammatory cytokines, among other adverse health effects. These immune system alterations are linked to higher infection risk and potentially contribute to autoimmune diseases and allergies later in life. For over four decades, Beyond Pesticides has tracked the peer-reviewed science and identified a preponderance of evidence linking pesticide and chemical-dependent pest management to adverse human and ecological health effects. In this spirit, public health and environmental advocates continue to call for a wholesale transition to organic land management and organic pest management as biodiversity, public health, and climate crises continue to mount. This mission supports the growth of the Parks for a Sustainable Future Program, where nineteen cities in eleven states across the country engage in pilot projects to transition parks, playing fields, and schoolyards to organic management practices and protect the health of children. Background and Methodology “This study aimed to evaluate the extent of immunotoxicity and correlation between exposure to pesticides and immune system alterations in children under five years […]

(Beyond Pesticides, October 23, 2025) A global literature review of pesticide residues in marine seaweed, published in Marine Pollution Bulletin, highlights the widespread presence of pesticides in bioindicator species. As vital coastal primary producers, seaweed acts as a key indicator for regional pesticide contamination patterns. The bioaccumulation within seaweed species also threatens consumers, including humans, as the chemicals can biomagnify as they move through the food web. Pesticide contamination in waterways allows residues to bioaccumulate in seaweed species, presenting risks to public health, biodiversity, and ecosystem functioning. In addition to the support seaweeds provide for ecosystems, they provide food sources for a multitude of organisms and are of growing socioeconomic importance. “This systematic review identifies, critically evaluates, and synthesizes recent global literature (2015–2024) on pesticide residues detected in seaweeds to delineate contamination patterns,” the authors share. The findings highlight the harmful impacts of petrochemical pesticides on multiple species. Many aquatic species rely on seaweed as a food source, including fish, sea urchins, crabs, snails, brittle stars, and marine mammals such as manatees and sea turtles. Even bacteria and filter feeders consume seaweed when it is decomposed. Birds and land mammals also consume seaweed, including humans who utilize seaweed in various […]

(Beyond Pesticides, October 22, 2025) The release of scientific studies on contaminants in sewage sludge (biosolids) used as fertilizers coincides with two lawsuits filed by Beyond Pesticides against ScottsMiracle-Gro and GreenTechnologies, LLC, in which the organization alleged that each defendant engaged in false and deceptive marketing and sale of fertilizer products that were marketed as environmentally friendly, despite containing per- and polyfluoroalkyl substances (“PFAS”). PFAS have been linked to cancer and other adverse effects. (See settlement statement recently reached with ScottsMiracle-Gro.) Biosolids are widely used in agricultural production and nonagricultural land management, including parks and playing fields, but  prohibited from use in certified organic agriculture under the Organic Foods Production Act. Two recent studies raise serious concerns about a range of contaminants in treated sewage sludge. While widely advanced as supplementing organic matter with macro- and micro-nutrients, treated sludge “harbor[s] a concentrated presence of contaminants that have adsorbed onto the soil post-wastewater treatment,” according to a literature review published in Frontiers in Environmental Chemistry. The researchers identify 414 contaminants of emerging concern (CECs) in soils, untreated and treated sewage sludge (biosolids), and dust, across 151 peer-reviewed studies released between 2018 and 2023—emphasizing the range of potential exposure pathways across various […]

(Beyond Pesticides, October 20, 2025) With the release of a study that links the use of nitrogen fertilizer in combination with antibiotic pesticides to escalating bacterial resistance, public health advocates are renewing their call for the U.S. Environmental Protection Agency (EPA) and the U.S. Congress to eliminate antibiotic pesticide use in land management. This action comes on the heels of a World Health Organization (WHO) study finding that antibiotic resistance is evolving even faster than previously thought. WHO finds, “One in six laboratory-confirmed bacterial infections causing common infections in people worldwide in 2023 were resistant to antibiotic treatments. . .. Between 2018 and 2023, antibiotic resistance rose in over 40% of the pathogen-antibiotic combinations monitored, with an average annual increase of 5–15%.”  These findings, linking pesticides, antibiotics, and nitrogen fertilizers to antibiotic resistance, again raise serious concerns about the deadly impacts of conventional (chemical-intensive) agricultural practices on human health. The researchers found that nitrogen is a strong driver of resistance processes. The richness and diversity of phages—viruses that attack bacteria and can transmit antibiotic resistance genes (ARGs)—is highest in the groups exposed to both nitrogen and combined pesticides, and the abundance of ARGs in phages becomes “markedly elevated” in those same exposure conditions.  Bacterial […]
