Latest State of the Birds Report Highlights Population Declines Indicative of Deteriorating Ecosystem Health

(Beyond Pesticides, March 20, 2025) An article, published by the National Audubon Society, titled “A Sweeping New Report Shows U.S. Birds Declining Sharply Across a Range of Habitats” reviews the latest State of the Birds 2025 report and finds concerning news for bird species across the country. As the article says: “Whether they hop around the prairie, dabble in wetlands, flit through forests, or forage along the shore, birds are suffering rapid population declines across the United States… If these habitats are struggling to support bird species, it’s a sign that they’re not healthy for other wildlife, or even humans—but working to restore them will have benefits across ecosystems.” The 2025 edition of the State of the Birds report, showcasing a status assessment of the health of the nation’s bird populations, was cultivated by scientists from bird conservation groups through the U.S. Committee of the North American Bird Conservation Initiative (NABCI). The report notes, “Despite ample evidence that conservation can work, the status quo approach to conservation is not turning bird populations around.” As NABCI shares, the report contains “[s]obering evidence that America’s birds continue to decline across the board.” They continue, saying: “Birds are telling us that the habitats […]

Historic Coexistence of Organic Agriculture and Nature Interrupted by Forced Farm Closures at Point Reyes National Seashore

*** Beyond Pesticides has recently received an insulting broadside from an environmental group; click here to read the original email and a response from the organization that includes a deep history of Beyond Pesticides’ commitment to ecological and organic farming practices in local food systems that are just.  (Beyond Pesticides, February 26, 2025) The National Park Service (NPS) recently announced a settlement agreement regarding the management of northern California’s Point Reyes National Seashore (PRNS) that will result in the closure of 12 out of 14 historic dairy and cattle ranches, including those organically managed, within the park. This decision comes after nearly a decade of legal disputes and negotiations between environmental groups, ranchers, and the NPS, ending 170 years of family ranching, displacing multi-generational farmers—at least 90 farmworker families—and abandoning 77 historic ranch buildings. Critics lambast the agreement as devastating local organic agriculture and food production in West Marin County, which is essential for creating long-term climate solutions. Over the decades since PRNS’ inception, local and national environmental groups have litigated against ranchers and the National Park Service, including demanding range expansion for the native tule elk, which were reintroduced to the park by NPS in the 1970s. However, the […]

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.” […]

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 […]

Study Finds Pesticide Exposure to Bees During Dormancy or Overwintering Disruptive of Reproductive Health

(Beyond Pesticides, January 30, 2025) A research article in Biology Letters, published by The Royal Society, finds that the neonicotinoid insecticide imidacloprid disrupts survival and reproductive patterns in Bombus impatiens bumblebees. The study adds to the wide body of science highlighting how exposure to pesticides “can result in immediate mortality or cause long-term detrimental effects on pollinators‘ health, lifespan and reproductive success,” the authors state. The researchers performed two experiments to assess the effects of various concentrations of imidacloprid, one of which focuses on bees during diapause, a period of dormancy. “Wild bees, which provide the majority of pollination services worldwide, undergo an annual life cycle that includes a winter diapause, that can span over 75% of their life cycle and during which their metabolism, growth and development are halted,” the authors note. They continue: “The time spent in diapause can have lasting effects on pollinator fitness and their ability to establish nests or colonies in the following spring. This period is especially critical for social bee colonies, which are founded by a single queen after diapause and play a vital role in large-scale pollination.” Exposure to pesticides during diapause can occur while bee species overwinter in contaminated soils.

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. This species has a complex life cycle requiring a mosaic of different habitat types, […]

Biodiversity Threatened by Pesticide Drift, Study Finds; Organic Agriculture Cited as a Holistic Solution

(Beyond Pesticides, January 3, 2025) Pesticides that are sprayed and become airborne significantly disrupt ecological balances and affect nontarget species that are crucial for maintaining biodiversity, according to an article in Environmental Pollution. In this review of studies throughout countries in North and South America, Europe, and Asia, among others, researchers from Germany, Norway, the United Kingdom, and Poland reinforce the science about pesticides’ direct effect on species and the cascading effects of pesticide drift through various trophic levels within food webs that lead to overall devasting population effects. This study “addresses the interconnectedness of these impacts and illustrates the complex threats that pesticide drift poses to biodiversity across multiple ecosystems,” the researchers state. They continue: “Impacts include reduced reproductive rates, changes in growth, development, and/or behavior, modification of diversity or community organization, disruption of food webs, and declines of important species. Pesticides disrupt the delicate balance between species that define a functioning ecosystem. Impacts can be local, transnational, or even continental.” Pesticide drift threatens beneficial species and subsequently the entire agricultural system. The process of pesticide drift, “in which up to 25% of applied pesticides are carried by air currents, can transport chemicals over hundreds or even thousands of […]

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 […]

Widely Used Insecticide Imidacloprid Negatively Impacts Soil Communities, Study Finds

(Beyond Pesticides, December 10, 2024) Scientists from the Engineering Research Center of Protection and Utilization of Plant Resources at Shenyang Agricultural University in China reveal adverse effects of imidacloprid on soil communities in a study published in Pesticide Biochemistry and Physiology. The researchers highlight risks to nematodes from imidacloprid exposure in maize soil, as well as potential resistance mechanisms that impact not only nematode populations but also overall soil health. Maize, or corn, a productive crop grown worldwide, is a source of food and biofuel. In assessing the soil and species in maize fields after exposure to imidacloprid at various concentrations, the study researchers assess the impact of neonicotinoid insecticides on nontarget organisms and the health of soil communities. The assessment includes an evaluation of nematodes’ survival, growth, reproduction, and chemotaxis/locomotion behavior. With a statistical analysis of lipid and lipofuscin accumulation, acetylcholinesterase (an enzyme necessary for neurotransmission) activity, and gene expression levels, the study results show that imidacloprid induces: significantly reduced abundance and diversity of nematode species. negative effects on body length, reproduction, locomotion, lipid accumulation, lipofuscin accumulation, and acetylcholinesterase activity in Caenorhabditis elegans ( elegans). the upregulation of gpa-1, cyp-35a2, fat-2, fat-6, hsp-16.41, and hsp-16.2, along with the downregulation […]

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. Reference additional Daily News coverage on ground-nesting bees here and here. “â€Our findings show that over 70% of wild bee species, which are crucial for pollinating our food crops, face significant risks […]

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, […]

Continued Decline in Insect Species Biodiversity with Agricultural Pesticide Use Documented

(Beyond Pesticides, September 11, 2024) A literature review in Environments, written by researchers from South Korea and Ghana, highlights the threat to nontarget species and the biodiversity of insects that occur as a result of agricultural pesticide use. “Insects have experienced a greater species abundance decline than birds, plants, and other organisms, which could pose a significant challenge to global ecosystem management. Although other factors such as urbanisation, deforestation, monoculture, and industrialisation may have contributed to the decline in insect species, the extensive application of agro-chemicals appears to cause the most serious threat,” the authors state. The so-called “insect apocalypse” has been reported with one-quarter of the global insect population lost since 1990.  The authors, seeking to summarize the decline in insect species richness and abundance, link reliance on petrochemical pesticides and synthetic fertilizers to cascading negative impacts. Insects provide many important services, such as maintaining healthy soil, recycling nutrients, pollinating flowers and crops, and controlling pests. These nontarget and beneficial species are at risk through pesticide exposure, both directly and indirectly, which then affects these essential functions.   “Extensive and indiscriminate pesticide application on a commercial scale affects insect species abundance and non-target organisms by interfering with their growth, […]

Healthy Ecosystems Essential to Cost-Effective Pest Management and Protection of Health

(Beyond Pesticides, September 10, 2024) Results from a natural experiment, published in Science, shows ecosystem disruption of bat populations with cascading impacts on human health. Eyal Frank, PhD, an assistant professor of the Harris School of Public Policy at the University of Chicago, links increased insecticide use in croplands in the absence of bat species to a rise in infant mortality. As Dr. Frank says in an article in Science Daily, “[B]ats do add value to society in their role as natural pesticides, and this study shows that their decline can be harmful to humans.”  Many farmers rely on bats as alternatives to pesticides to protect their crops from insects, but White-Nose Syndrome (WNS) has greatly impacted bat populations since 2006. With the collapse of many bat populations in counties in North America, these farmers turn to toxic chemicals to replace the ecosystem services bats usually provide. These chemicals, however, lead to ripples through the ecosystem and endanger human health.  WNS is an invasive fungus (Pseudogymnoascus destructans) found in caves that affects bats during hibernation. As highlighted in an article in the New York Times, three species of bats in North America have been decimated by this syndrome, and bats […]

Biofungicides Show Promise in Agriculture and Land Management, Study Finds

(Beyond Pesticides, September 6, 2024) A literature review in the Internal Journal of Molecular Sciences provides promising insights into biofungicides as a “sustainable and economically viable alternative” to synthetic fungicides in expanding organic agriculture. The authors note that organic “… is the most sustainable response to current crises of all kinds, as it can better anticipate and prepare for crises and create long-term equity and resilience in food systems.” The authors point out that fungal infections in crops are estimated to account for 20-40% of failures annually, and understanding how to control such agricultural diseases will be crucial to meeting the needs of a growing global population. Organic farmers and land managers note that biological tools can be integrated into practices that work with the ecosystem, rather than be utilized as “substitute” products or controls with practices that ignore soil health and beneficial organisms that enhance biodiversity and provide ecosystem services (see here and here). Conducted by researchers in Mexico, the review examines data on biosynthesis (how plants create their own fungicide, known as secondary metabolites or SMs); the mechanisms of action of secondary metabolites against phytopathogenic (plant-killing) fungi; extraction techniques and biofungicide formulations; the biological activity of plant extracts on phytopathogenic fungi; and […]

Scientific Findings Call for Urgent Action in Just Released Issue of Pesticides and You

(Beyond Pesticides, July 26, 2024) Beyond Pesticides released the latest issue of Pesticides and You this week, a compendium of scientific research on pesticide threats to human and environmental health. The issue is a breathtaking warning from the science community that environmental, health, and labor laws are not protecting the public. Beyond Pesticides says in its introduction that a shift away from toxic pesticide use is urgently needed. Included in this issue are scientific reviews of research reported by Beyond Pesticides in 2023, providing a critique of the independent peer-reviewed literature with a shocking range of adverse effects, including cancer, neurotoxicity, brain effects, reproductive impacts, diabetes and obesity, chronic kidney and liver disease, Parkinson’s, respiratory illness and asthma, learning and behavioral abnormalities, and more, as well as disproportionate harm to people of color. In addition, the science documents pesticides’ catastrophic harm to the ecosystems that sustain life. In total, these dramatic findings call for an end to the use of toxic pesticides, incompatible with respect for living organisms and, to environmental, health, and labor advocates, unconscionable given the availability of viable, cost-effective organic practices. This issue adds to the body of knowledge from two previous issues of Pesticides and You (Transformative Change: […]

Literature Review Analyzes Pesticide Sensitivity in Bee Species on a Molecular Level

(Beyond Pesticides, June 21, 2024) A recent review of the scientific literature, published in Science of The Total Environment, analyzes multiple species of bees on a molecular level to better understand the poisoning mechanisms that could, as the authors see it, inform chemical risk assessments with more precision. The mechanisms “implicated in the tolerance of bees to specific pesticides, and thus as determinants of insecticide sensitivity, … include metabolic detoxification, insecticide target proteins, the insect cuticle and bee gut microbiota,” the authors write. This review references more than 90 studies performed over the last 30+ years, with most being published in the last 5-10 years, as the understanding and importance of molecular determinants of bee sensitivity has emerged. Pollinators, such as bees, provide crucial ecosystem services by pollinating both wild plants and essential crops. The exposure these insects are subjected to threatens their existence, which occurs through pesticide contamination that can lead to impacts on growth and development or even colony collapse.    “While bees have only been exposed to human-made pesticides over the recent past (last 80 years) they have co-evolved with plants and fungi which produce a range of xenobiotics, including plant allelochemicals and mycotoxins,” the authors state.

Study Confirms Serious Flaws in EPA’s Ecological Risk Assessments, Threatening Bees and Other Pollinators

(Beyond Pesticides, June 13, 2024) A study published in Conservation Letters, a journal of the Society for Conservation Biology, exposes critical shortcomings in the U.S. Environmental Protection Agency’s (EPA) ecological risk assessment (ERA) process for modeling the risks that pesticides pose to bees and other pollinators. For the study, “Risk assessments underestimate threat of pesticides to wild bees,” researchers conducted a meta-analysis of toxicity data in EPA’s ECOTOX knowledgebase (ECOTOX), an EPA-hosted, publicly available resource with information on adverse effects of single chemical stressors to certain aquatic and terrestrial species. The meta-analysis found that the agency’s approach, which relies heavily on honey bee data from controlled laboratory studies, drastically underestimates the real-world threats from neonicotinoid insecticides (and likely other pesticides) to native bees and other pollinators. The study “challenges the reliability of surrogate species as predictors when extrapolating pesticide toxicity data to wild pollinators and recommends solutions to address the (a)biotic interactions occurring in nature that make such extrapolations unreliable in the ERA process.” Beyond Pesticides executive director Jay Feldman remarked, “EPA’s ecological risk assessment process is fundamentally flawed and puts thousands of bee species at risk of pesticide-caused population declines and extinctions.” Mr. Feldman continued, “This underscores the urgent […]

Pesticide-Contaminated Algae Found to Jeopardize Ecosystems and Human Well-Being [Study]

(Beyond Pesticides, June 12, 2024) A study of pesticide contaminated algae finds that the disruption of algal communities has a devastating effect on the health of the aquatic food web. The study findings show that contact with pesticides can result in changes to “algal physiology, causing tissue injury, developmental delay, genotoxicity, procreative disruption, and tissue biomagnification” that alters the dominance of algae species in the environment. This in turn “can impact higher trophic levels and have a domino effect on the aquatic food web. It is possible for biodiversity to disappear, reducing ecosystem stability and resistance to environmental alterations,” the authors state. The study, a worldwide literature review conducted by researchers from India, South Korea, and Saudi Arabia, appears in Aquatic Toxicology.  The health of aquatic ecosystems is at risk with indirect effects on nontarget species from pesticides in the environment. This includes impacts on species of fish, invertebrates, microbial communities, and marine mammals. In explaining the importance of extensively studying effects of pesticides, the researchers note, “Different pesticide classes have different chemical structures, which define their modes of action and affect how they interact with both target and nontarget organisms.” Because of this, the range of effects seen from […]

Chemical-Intensive Practices in Florida Citrus Lead to Harm and Collapse, as Organic Methods Offer Path Forward

(Beyond Pesticides, April 11, 2024) Scientists are moving forward in testing an agroecological method of “push-pull” pest management (reducing the attractiveness of the target organism and luring pest insects towards a trap) to fight the Asian citrus psyllid (ACP) in Florida orange groves, as it spreads a plant disease known as the pathogenic bacteria huanglongbing (HLB), also known as citrus greening, which is deadly to citrus trees. The disease is spread by the pathogenic bacteria Candidatus Liberibacter asiaticus (CLas).  The chemical-intensive, or conventional, citrus industry is under intense pressure to find alternatives, as synthetic antibiotic use for this purpose has been successfully challenged in court. ACP is the carrier, or vector, for HLB, spreading it through the citrus groves and killing the trees. The chemical-intensive industry has focused on using antibiotics, which the environmental and public health community has rejected because of serious medical concerns associated with life-threatening bacterial resistance to antibiotics used to protect humans. A federal district court decision in December 2023 found illegal the U.S. Environmental Protection Agency’s (EPA) decision to register the antibiotic streptomycin in Florida citrus without adequate review of its impact on endangered species. The streptomycin lawsuit, filed in 2021 by a coalition of […]

Synthetic Turf Fields, Forever Chemicals and the Safer Alternative: Organic Grass

(Beyond Pesticides, March 27, 2024) A preliminary experiment conducted by Public Employees for Environmental Responsibility (PEER) reveals concerning levels of toxic per- and polyfluoroalkyl substances (PFAS) on the skin of soccer players and coaches after playing on artificial turf fields. The Washington Post reported on March 12 on the PEER test results, which found PFAS levels increased on the skin in three out of four participants following soccer matches on artificial turf. In contrast, no similar increase was observed after games on natural grass fields. The presence of PFAS is alarming due to their association with several serious health issues, including cancer, birth defects, and developmental and immune deficiencies, among others. The U.S. Environmental Protection Agency (EPA) writes that PFAS exposure risks are particularly concerning for young children, who are more susceptible due to their developing bodies and at risk for higher levels of exposure than adults. Known as “forever chemicals” for their persistence in the environment, PFAS continue to accumulate in the human body, posing long-term health risks. Kyla Bennett, PhD, science policy director at PEER and a former scientist and lawyer with EPA, emphasized the need for further research. “Although this study is preliminary, it highlights the potential […]
