Exposure to Glyphosate Herbicide Adversely Affects Perinatal Health, Study Finds

(Beyond Pesticides, February 20, 2025) Researchers at the University of Oregon found that the rollout of genetically engineered corn in the early 2000s, followed by exponential increases in glyphosate-based herbicides, “caused previously undocumented and unequal health costs for rural U.S. communities over the last 20 years.†Their results “suggest the introduction of GM [genetically modified] seeds and glyphosate significantly reduced average birthweight and gestational length.†The conclusions of this study emerge as fossil fuel advocates, including President Donald Trump, are mobilizing to pioneer “energy dominance†despite the market movement toward renewable energy. Just as chemical-intensive farmers and land managers continue to spray synthetic fertilizers and pesticides, a successful rollout of alternatives must rely on feeding the soil rather than the plant. Advocates continue to demand that elected officials and regulators embody the precautionary principle and scientific integrity in decision-making. Given the hostile federal climate on anything relating to holistic solutions, communities are coming together to move beyond input-dependent land management systems and adopt organic criteria of allowed and prohibited substances, mandatory public comment process, independent third-party certification, and a federal advisory board (National Organic Standards Board) consisting of farmers, environmentalists, consumers, scientists, economists, researchers, and other stakeholders, with binding recommendations […]

Bats in Organic Agriculture: Precision Foraging as Pest Management

(Beyond Pesticides, February 19, 2025) In Global Ecology and Conservation, a study of bat species in organic desert date palm plantations highlights the invaluable ecosystem services these beneficial organisms provide. “Bats are crucial in suppressing pest arthropods in agroecosystems, contributing vitally to sustainable agriculture,†the study authors share, which makes supporting bat populations important not just for biodiversity but to help enhance their roles in pest management.    There are various studies connecting organic agriculture and the value it provides for bats and their ecosystem services. (See studies here, here, and here.) While many studies also recognize bat species threatened by pesticides, habitat loss, and climate change, “the importance of bats in agriculture in extreme environments, such as deserts, has received far less attention,†the researchers state. (See previous coverage on pesticide exposure and bats here and here.) They continue, “Date palm plantations represent one of the few productive systems in hyper-arid regions,†noting the study’s novel design. The date palm, primarily grown throughout the Middle East and North Africa, is one of the earliest domesticated fruit trees. “The date palm cultivation’s monocultural nature increases susceptibility to pest infestations due to limited plant diversity, involving 112 mite and insect species.†[…]

Love Your Heart This Valentine’s Day by Following the Science on Pesticides

(Beyond Pesticides, February 14, 2025) A study in the European Journal of Preventive Cardiology finds that organic food consumption lowers the risk of developing atherosclerotic cardiovascular disease (ASCVD). Heart health is important not just on Valentine’s Day, but every day. While celebrating with friends and family, consider spreading love in ways that promote long-term health and wellness with an organic meal paired with organic flowers and chocolates. Eliminating exposure to petrochemical pesticides and synthetic fertilizers, such as with an organic diet, mitigates disease risks including brain and nervous system disorders, cancer, endocrine disruption, and cardiovascular disease (CVD). In this latest study, the scientists and doctors analyze registered diagnoses of ASCVD from the Danish National Patient Register in comparison with the diets of a cohort of middle-aged women and men from the Danish Diet, Cancer and Health study. The eligible study participants, including 41,407 men and women of which 5,365 developed ASCVD, filled in a detailed 192-item food frequency questionnaire and a lifestyle questionnaire on their consumption of organic vegetables, fruit, dairy products, eggs, meat, and bread and cereal products. The authors report that the results show overall organic food consumption is associated with a 6% lower incidence rate of ASCVD. […]

Study Finds Increased Offspring Mortality in Pesticide-Laden Bird’s Nests

(Beyond Pesticides, February 11, 2025) In a Science of The Total Environment study, scientists test over 100 blue tit (Cyanistes caeruleus) and great tit (Parus major) birds’ nests for pesticide residues in comparison with the number of dead offspring and unhatched eggs within the nest. Fur-lined nests, from animals treated with ectoparasitic chemicals, expose birds to compounds that can impact reproductive success. The authors found fipronil, a phenyl pyrazole insecticide, in all nests, with the majority also containing the neonicotinoid insecticide imidacloprid and synthetic pyrethroid insecticide permethrin. The data shows higher insecticide levels are linked to increased offspring mortality and threaten biodiversity. This study highlights an important exposure route that is overlooked. “Although not all bird species use fur for nest building, a substantial number do, especially cavity-nesting species,†the researchers share. “Previous research found that 74% of studied woodland bird species in central Europe incorporated fur into their nests.†Many bird species in the U.S. also line their nests with fur, such as black-capped chickadees, tufted titmice, and chipping sparrows. While there is a wide body of science showing reproductive effects from pesticides, the researchers highlight the study’s novel design, saying, “To the best of our knowledge, no previous […]

Neonic Insecticide Impairs/Kills Beetle Listed as Threatened and Important to Ecosystem Health, But Not Protected

(Beyond Pesticides, February 5, 2025) A study in PLOS One finds acute and chronic impacts of nontarget toxicity on the American burying beetle, Nicrophorus americanus, with neonicotinoid insecticide exposure. In assessing environmentally relevant concentrations of the neonicotinoid insecticide imidacloprid with N. americanus, the researchers note both mortality and behavioral effects that leave the species at high risk of predation. These effects mean the American burying beetle “may be at greater risk to insecticide exposure than previously thought and vulnerable to episodic, low-dose neonicotinoid exposure,†the authors say. This data sheds important light on a species that has been listed by the U.S. Fish and Wildlife Service (USFWS) as threatened. Burying beetles provide important ecosystem services within the environment such as “burying carrion, increasing available nutrients in soil, and expediting carrion decomposition, while acting as a food source for secondary consumers,†the researchers state. (See more on ecosystem services and beneficial insects here, here, and here.) The N. americanus species are habitat generalists and can be found in grasslands, wet meadows, and forested areas that neighbor agricultural lands and introduce the beetles to pesticide drift and soil residues. While acute and chronic effects vary in duration and severity, pesticide exposure resulting […]

Sleep Disorders in Farmers and Farmworkers Linked to Pesticide Exposure in Study Supporting Similar Findings

(Beyond Pesticides, January 31, 2025) A recent cross-sectional study in Heliyon highlights the link between sleep disorders in Thai farmers and pesticide exposure. The authors find pesticide exposure as an important risk factor for sleep disorders after surveying 27,334 farmers over the age of 20 who had work experience for at least five years. The importance of sleep health is reflected both physically and mentally, as studies find “sleep deficiency increase[s] mortality and various health complications, including hypertension, obesity and type 2 diabetes, cardiovascular diseases, mood disorders, and neurodegenerative disorder.†Additional studies find that these issues are compounded when sleep health is affected by environmental factors such as pesticide exposure. (See previous Beyond Pesticides’ coverage here and here.) The researchers report: “The study found a positive association of 19 individual pesticides (twelve insecticides, two herbicides, and five fungicides). Some associations demonstrated a dose-response pattern. Additionally, the study revealed that women are at a higher risk of sleep-related issues with pesticide exposure compared to males. These results not only substantiate existing literature but also unveil several new individual pesticides that may impact sleep health.†Focusing on study participants in Thailand, which is “characterized by heavy pesticide use and minimal protective measures, […]

Action Today: U.S. Fish and Wildlife Service Proposes Critical Habitat for Endangered Rusty Patched Bumble Bee

(Beyond Pesticides, January 27, 2025) A public comment period ends today, January 27, 2025, on the U.S. Fish and Wildlife Service’s (FWS) proposed critical habitat rule to protect the rusty patched bumble bee under the Endangered Species Act (ESA). This proposal is responsive to the agency’s 2024 stipulated settlement agreement resulting from years of advocacy and government review and a 2023 court order (NRDC et al. v. U.S. Fish and Wildlife Service, et al.). The proposal follows a 2017 determination by the agency that lists the bumble bee as an endangered species. (See previous Daily News here, here, here, here, and here.) >> Tell the U.S. Fish and Wildlife Service to fully protect the endangered rusty patched bumble bee by finalizing its proposed critical habitat rule with strengthening provisions. The FWS proposal grows out of a species status assessment (SSA) conducted by “15 scientists with expertise in bumble bee biology, habitat management, and stressors (factors negatively affecting the species).†University of Illinois Urbana-Champaign insect ecologist Jason Robinson, PhD concludes in his paper, “Project-specific bumble bee habitat quality assessment,†“As the first social insect listed under the ESA, the listing of RPBB has required new methods for biological assessment.

Reflections on Martin Luther King Day, Prioritizing Environmental Justice Given Disproportionate Existential Threats

(Beyond Pesticides, January 17-20, 2025) Martin Luther King Day recognizes the achievements of a remarkable civil rights leader while asking the nation to assess what more the country must do to ensure equality and environmental justice, as well as protection for those who suffer disproportionately from toxic chemical exposure. Advocates and disproportionately affected communities acknowledge the historic nature of the Biden Administration’s commitment to elevating environmental justice in the decision-making of the U.S. Environmental Protection Agency (EPA). However, according to Willy Blackmore, writer for Minnesota Spokesman-Recorder (“the oldest Black-owned newspaper in the state of Minnesota and one of the longest-standing, family-owned newspapers in the countryâ€), “[T]he more systemic change that [Administrator] Regan’s EPA tried to bring about was stonewalled by legal challenges that threatened to undermine the agency’s strongest tool for righting environmental injustices.†Black communities across the nation face disproportionate impacts to petrochemical infrastructure and toxic chemicals, including pesticides and fertilizers.

Multitude of Studies Find Epigenetic Effects from PFAS and Other Endocrine Disrupting Pesticides

(Beyond Pesticides, January 16, 2025) In Ecotoxicology and Environmental Safety, researchers highlight a multitude of studies on endocrine disrupting chemicals (EDCs) and endocrine disrupting pesticides (EDPs) showing epigenetic effects from exposure. These EDCs imitate the action of endocrine hormones and lead to gene damage and multigenerational adverse effects to health. “These chemicals can interfere with the normal functioning of target tissues by altering their response to hormonal signals, thereby affecting various physiological processes including reproduction, development, the nervous system, the immune system, and even the process of carcinogenesis [causing cancer],†according to the authors from Hebei Agricultural University and Chinese Academy of Agricultural Sciences.   In causing epigenetic modifications, the authors describe that EDCs can create changes “at the nuclear and mitochondrial DNA (nDNA and mtDNA) or RNA levels, without changing the underlying DNA sequence. These alterations modify the structure or conformation of DNA, influencing gene expression and, consequently, cellular function.†They continue, “The mechanisms of epigenetics include changes in DNA methylation, chromatin modifications and the involvement of certain noncoding RNAs.†In reviewing over 80 studies on EDCs, predominantly fluorinated compounds such as per- and polyfluoroalkyl substances (PFAS), the researchers provide a summary of linkages between pesticide exposure and the […]

Pesticides Harming Immune Cell Function Linked to Elevated Breast Cancer Rate in Young Women

(Beyond Pesticides, January 14, 2025) Women with occupational pesticide exposure have elevated rates of breast cancer, according to a study in Immunopharmacology and Immunotoxicology. Based on an analysis of clinicopathological data from 188 affected women, the study authors demonstrate “that occupational exposure to pesticides modifies the clinical presentation of disease in breast cancer patients, depending on their age at disease onset, affecting cytokine production, especially in those exhibiting early age at diagnosis.â€Â Â  “Breast cancer (BC) is the most common malignant neoplasm affecting women worldwide and the second leading cause of cancer-related death in this population,†the researchers report. They continue: “Aging is the primary risk factor associated with breast cancer development and mortality, resulting in a cumulative lifetime risk of 1 in 8 women developing the disease. Disease onset significantly impacts patient prognosis. While most cases are of late onset and occur in women over 50 years of age, early-onset BC is prevalent in certain populations and is associated with a poor prognosis and aggressive tumor behavior.â€Â  Data was collected and analyzed from May 2015 to December 2022, with the study population in Brazil spanning “27 municipalities in the southwest of Paraná, a region characterized by extensive pesticide use, predominantly […]

Federal Court Reverses Genetically Engineered Crop Deregulation Adopted by First Trump Administration

(Beyond Pesticides, January 8, 2025) On the brink of the second Trump administration, a legal victory just last month overturned a rule issued under the first Trump administration to “practically eliminate oversight of novel GE technology and instead let industry self-regulate,†as characterized by the Center for Food Safety (CFS). CFS served as counsel in the case for the plaintiffs, led by the National Family Farm Coalition. The U.S. District Court for the Northern District of California decision, responding to the lawsuit filed in 2021 on behalf of farm and environmental groups, remanded the case back to the U.S. Department of Agriculture (USDA) with instructions to follow. “This is a critical victory on behalf of farmers, the planet, and scientific integrity,” says George Kimbrell, legal director at the Center for Food Safety, also a plaintiff in the case. Mr. Kimbrell continued, “USDA tried to hand over its job to Monsanto and the pesticide industry and the Court held that capitulation contrary to both law and science.” It remains to be seen whether the incoming Trump administration will appeal this court decision.

Report Links Biodiversity, Water, Food, and Health In Critique To Avert Escalating Crises

(Beyond Pesticides, January 7, 2025) A report, released in December 2024 from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), confronts the problem of “siloing†environmental elements—food, health, water, biodiversity and climate change—when they instead intersect at a nexus from which each element affects all the others. The problem is essentially that all the elements are part of the same crisis, yet actions to address issues within each—and, importantly, to resist addressing them—are dealt with in isolation. A proper perspective, gleaned from the report, is to view each element from the center where all parts meet, thus addressing the issues in coordination. According to the IPBES report, “[F]ragmented governance of biodiversity, water, food, health and climate change with different institutions and actors often working on disconnected and siloed policy agendas, resulting in conflicting objectives and duplication of efforts.†The IPBES is an independent body analogous to the Intergovernmental Panel on Climate Change (IPCC) but structured similarly and in close contact with the United Nations (UN). The new report comes at the behest of IPBES’s 147 member countries—75 percent of the UN’s membership—to address the interconnections among the five global crises. The report strongly demonstrates that a holistic, globe-spanning frame […]

Proposed Protections for Monarch Butterflies Highlights Pesticide Threats to Biodiversity Essential to Life

Image: Art Page submission from Carol Moyer, “Monarch Butterfly Sideways with Closed Wings.“ (Beyond Pesticides, December 20, 2024) On December 12, the U.S. Fish and Wildlife Service (FWS) opened a public comment period on its proposal to list the monarch butterfly (Danaus plexippus) as a threatened species and to designate critical habitats for the species under the Endangered Species Act of 1973. Under the proposal, the designated habitats would span approximately 4,395 acres throughout overwintering sites in coastal California. The public comment period will be open until March 12, 2025. These suggested protections call attention to the role of chemical-intensive agriculture in affecting populations of pollinators and other beneficial organisms. George Kimbrell, legal director at the Center for Food Safety, shares in a press release that the “monarch listing decision is a landmark victory 10 years in the making. It is also a damning precedent, revealing the driving role of pesticides and industrial agriculture in the ongoing extinction crisis… But the job isn’t done: Monarchs still face an onslaught of pesticides. The Service must do what science and the law require and promptly finalize protection for monarchs.†In the docket, FWS states, “Under the Act, a species warrants listing if […]

Deadly Poisoning of Dozens of Children in South Africa Highlights Global Pesticide Threat to Human Life  

(Beyond Pesticides, December 19, 2024) As The New York Times reported last month, the government in South Africa declared a national emergency—23 children died and nearly 900 people were sickened from pesticide poisoning in Johannesburg’s Soweto township. The illnesses and fatalities have been traced to small amounts of highly neurotoxic pesticides, including the insecticides terbufos and aldicarb, found in local food items. These chemicals, described by South African President Cyril Ramaphosa as “street pesticides,†are being increasingly used (legally and illegally) for pest infestations in the townships and informal settlements of South Africa’s poorest communities, where poverty and inadequate waste collection exacerbates the pest management challenges. Without formal electricity, running water, or municipal garbage collection, many residents rely on highly toxic pesticides for pest infestations in their homes and makeshift markets, resulting in food inadvertently being contaminated with pesticides.  The announcement highlights the dangers of allowing these highly toxic agricultural chemicals to be used in farming, with tragic consequences for vulnerable communities when they are diverted for use in urban settings. This tragic situation also draws attention to the elevated threat that pesticides pose when stringent enforcement mechanisms are not in place to ensure compliance with pesticide restrictions, even with […]

Study Links Numerous Chemical Families of Pesticides to Endocrine Disrupting Effects, Including Obesity

(Beyond Pesticides, December 17, 2024) A systematic review of studies on pesticides as endocrine-disrupting chemicals (EDCs) on body weight, published in Biomedicines, evaluates 36 clinical and preclinical studies and links their agricultural use to obesity. The authors, with the lead researchers from the School of Medicine and Health Sciences at Catholic University of Valencia San Vincente, Valencia, Spain, assess studies on a range of pesticides, including organophosphates, pyrethroids, neonicotinoids, and others. In addition to concluding that the EDCs promote obesity, they report that the chemicals cause “other anthropometric changes by altering lipid and glucose metabolism, modifying genes, or altering hormone levels such as leptin.†Endocrine disruption and obesity are public health concerns, and there is a wide body of science linking pesticide exposure to these effects (see more here). “Obesity is considered to be a worldwide pandemic that leads to an increase in medical costs and thus becomes a public health problem,†the researchers share. They continue, “[Obesity] is also associated with the increased production of environmental chemicals, also called environmental obesogens, used mainly in agriculture, as disease vector control, helping to prevent harmful effects caused by fungi, bacteria, or even pests, using pesticides, insecticides, and herbicides, or endocrine disruptors […]

California Asked To Put an End to a Deadly Fumigant Used on Food Eaten Nationwide

(Beyond Pesticides, December 16, 2024) The fact that three-quarters of all U.S. fruits and nuts and one-third of all U.S. vegetables are grown in California means that all U.S. food eaters have a stake in how food is grown there. California is proposing the continued use of the fumigant 1,3-dichloropropene (1,3-D, also known as Telone), which can cause deadly effects to farmworkers and endocrine disrupting effects to communities of people exposed through nontarget chemical drift from farmland. So, it is with deep concern that Beyond Pesticides is urging the state of California, where the chemical is undergoing review, to ban the toxicant. Endocrine disruption, an adverse effect for which the U.S. Environmental Protection Agency (EPA) has never completed a pesticide testing protocol, adversely affects the functioning of glands and hormones and is linked to major life-threatening diseases in most organ systems in the body—contributing to attention deficit hyperactivity disorder (ADHD), Parkinson’s, Alzheimer’s, diabetes, cardiovascular disease, obesity, early puberty, infertility and other reproductive disorders, and childhood and adult cancers. In a recently released draft regulation, the California Department of Pesticide Regulation (CDPR) will allow highly elevated exposure to 1,3-D, ignoring the scientific literature and advice of the state’s own toxicologists at […]

EPA’s Registration of Herbicide under New Framework Puts Endangered Species at Elevated Risk, Advocates Say

(Beyond Pesticides, December 13, 2024) In October, the U.S. Environmental Protection Agency (EPA) approved the registration applications of BASF Corporation and Mitsui Chemicals Crop & Life Solutions, Inc. for the use of different formulations of the L-isomer of glufosinate (also known as “L-glufosinate†and “glufosinate-Pâ€) as new active herbicidal ingredients. This decision marks one of the first times that EPA has employed its new Herbicide  Strategy Framework to determine the level of mitigation necessary to protect listed species and critical habitat under the Endangered Species Act (ESA). Glufosinate is an organophosphate, with known neurotoxic, reproductive/developmental effects, toxic to aquatic life, and mobile in soils (see Beyond Pesticides Gateway). Scientists have found that formulated glufosinate is generally more toxic to aquatic and terrestrial animals than the technical grade active ingredient. Manufacturers are introducing newer glufosinate products as alternatives for glyphosate-based herbicides, like Bayer/Monsanto’s ‘Roundup’ and dicamba. The Center for Biological Diversity notes in comments submitted to EPA on this decision, “L-glufosinate has the potential to be used on tens of millions acres of land every year given the crops EPA has proposed to register it on. The scale of potential use is far above most new active ingredients.†This first significant application […]

Review Cites Memory and Learning Impairments; Children, Workers, and Nontarget Organisms at Risk

(Beyond Pesticides, December 12, 2024) A literature review of 161 articles in Discover Toxicology finds that pesticides with different mechanisms of action cause memory and learning impairments. These effects are noted in nontarget species including humans. Pesticide “[e]xposure during development, as well as chronic environmental and occupational exposure, can contribute to decreased cognitive performance,†the researchers say. With a focus on organophosphate pesticides, synthetic pyrethroids, and neonicotinoid insecticides, the authors highlight neurological impacts. Both learning and memory are crucial for the survival of many species. “Considering the importance of learning and memory for human and non-human animal behavior and the growing association between pesticide exposure and cognitive impairment, the aim of this review was to describe the studies showing the impact of pesticide exposure on memory and learning abilities in nontarget species, providing evidence of the impact of pesticides in central nervous system function,†the researchers state. The 161 articles included in the review were identified through database searches in PubMed/Medline and Scielo. The authors note, “Inclusion criteria for article selection included all articles published in English between 2015 and 2024 containing original studies in animals or humans with single or multiple pesticides exposure.†The articles consist of 132 preclinical […]

Studies Cite Risk Assessment and Regulatory Deficiencies in Protecting Ground-Nesting Bees

(Beyond Pesticides, December 3, 2024) In an article in Science, Sabrina Rondeau, PhD reviews her research from 2022-2024 showcasing species of ground-nesting bees, often found in crop fields, that are highly vulnerable to soil pesticide residues and subsequently suffer population declines. Dr. Rondeau, a postdoctoral fellow in the Department of Biology at the University of Ottawa, points to regulatory deficiencies, specifically in environmental risk assessments (ERAs), and the detrimental effects of pesticides on pollinators that threaten food security and biodiversity. “Modern intensive agriculture faces a critical paradox: The very pesticides designed to protect our crops endanger essential pollinators that sustain their productivity,†Dr. Rondeau says in the article. Her research (see here, here, here, here, here, and here) identifies important gaps overlooked in current assessments and regulations for bee species, including the common eastern bumble bee (Bombus impatiens) and the hoary squash bee (Xenoglossa pruinosa). Bumble bee queens in temperate climates hibernate for 6-9 months in the soil, while the hoary squash bee is a solitary ground-nesting species.

Pesticide Exposure in Early Childhood Linked to Neurobehavioral Disorders, Study Finds

(Beyond Pesticides, November 26, 2024) A study in Environment International finds that young children who exhibit higher levels of pesticide metabolites in their urine show more pronounced neurobehavioral problems at the age of ten. Researchers in China document how exposure during early childhood, especially during the sensitive window before the age of two, is linked to hyperactivity/inattention problems such as attention deficit hyperactivity disorder (ADHD). While adding to the body of science connecting pesticide exposure to learning and developmental disorders, this study offers a “novel perspective on characterizing the fluctuation in repeated measurements of multiple environmental chemicals and identifying the potential critical windows,†the authors share. (See previous Daily News coverage here, here, and here.) The researchers analyze data from questionnaires and urine samples through the ongoing Sheyang Mini Birth Cohort Study (SMBCS), which is a long-term prospective cohort study that associates environmental chemical exposure during pregnancy and childhood to negative health effects. This data addresses combined pesticide exposures in young children with neurobehavior analyses at the age of ten to determine any correlation.

Study Reinforces Importance of Biodiversity in Agriculture and Ecosystem Health

(Beyond Pesticides, November 6, 2024) An analysis in the International Journal of Research Publication and Reviews emphasizes the role of biodiversity in agriculture, adding to a wide body of science on its importance. The authors, from Western Illinois University in the United States and Rome Business School in Italy, find that biodiversity supports critical ecosystems and organisms needed for sustainable food production. Through literature reviews and case studies, the interconnectedness of agriculture with plant and animal diversity, beneficial insects, soil health, and climate change is highlighted, as well as the need to manage land organically to support biodiversity. Plant and Animal Diversity As the researchers note, “A diverse agricultural system can better absorb shocks and maintain productivity, ensuring food security in the face of uncertainty.†A wide range of species present within ecosystems protects from changing environmental conditions and improves resilience. When farmers use monocultures for their crops, this leads to reduced ecosystem services from beneficial insects and increased vulnerability to pests and diseases. “By contrast, diverse cropping systems can enhance resilience, providing a buffer against environmental changes and fostering sustainable food production,†the authors say. Research shows that higher plant diversity disrupts pest life cycles and promotes beneficial insects, […]

Study Shows Climate Change Exacerbates Synergistic Effects of Synthetic Pyrethroid on Biodiversity

(Beyond Pesticides, October 25, 2024) To better understand synergistic interactions between multiple stressors, researchers from the Helmholtz Centre for Environmental Research in Leipzig, Germany, analyze exposure to the pyrethroid insecticide esfenvalerate with two nonchemical environmental factors: elevated temperature and food limitation. In their recent publication in Environmental Pollution, the authors find the greatest synergistic effects when Daphnia magna (D. magna) are subjected to esfenvalerate under conditions experienced with climate change including lower food availability and increased temperature. D. magna, also known as daphnids or water fleas, are small planktonic crustaceans that represent an essential part of the food web in lakes and ponds. Impacts on populations of daphnids can lead to effects throughout multiple trophic levels that impact overall biodiversity. As the researchers state, “Global biodiversity is declining at an unprecedented rate in response to multiple environmental stressors… A key challenge is understanding synergistic interactions between multiple stressors and predicting their combined effects.†To study this, a Stress Addition Model (SAM), which predicts the cumulative effects of interacting stressors, was utilized and compared to laboratory data using 24-hour-old neonates of D. magna. The organisms were subjected to various conditions, singularly and in combination, including increased temperature, lower quantities of food, […]

Commentary: Expected Trump Blueprint, Project 2025, To Subvert Environmental Law as Crises Mount

(Beyond Pesticides, October 23, 2024) The stark contrast of two political parties emerged around this summer’s reporting of the Project 2025 blueprint—created by extreme right-wing conservatives—that proposes the gutting of environmental and public health policy and implementation. Many political observers say “Project 2025 Presidential Transition Project,” formally titled “Mandate for Leadership: The Conservative Promise,” will be embraced by a second Trump Administration, despite denials that are challenged by insiders as outright lies. While the public became aware of Project 2025 plans to gut the U.S. Environmental Protection Agency (EPA) and many other agencies, the Biden Administration was announcing the emergency ban (see also August 6 announcement), finalized yesterday, of the weed killer Dacthal, exercising an EPA authority that has not been used in 45 years since the banning of 2,4,5-T (50% of the mixture of Agent Orange). With this decision, EPA set an important precedent for proclaiming (i) an unacceptable harm, (ii) its inability to mitigate the pesticide’s hazards with typical risk mitigation measures, and (iii) the availability of alternatives that made the chemical unnecessary. In dramatic contrast, the Trump supporters behind Project 2025 are intent on politicizing science to undermine governmental structures and laws established to protect public health […]
