(Beyond Pesticides, July 31, 2024) The latest commentary on âforever chemicalsâ in Environmental Health Perspectives captures growing concerns for the class of per- and polyfluoroalkyl substances (PFAS) that are found in pesticide products and cause persistent contamination that threaten human health and the environment. The authors share, âGiven that pesticides are some of the most widely distributed pollutants across the world, the legacy impacts of PFAS addition into pesticide products could be widespread and have wide-ranging implications on agriculture and food and water contamination.â Fluorination, which adds fluorine to a compound, is used to modify properties, such as the stability of chemicals. It can also increase residual activity of pesticide ingredients. Fluorinated molecules, including PFAS, are âa serious environmental health concern owing to their highly persistent nature, often potent toxicities, potential to bioaccumulate, and widespread presence in people, animals, and the broader environment,â the authors state. They continue in saying, âThe long-term impacts of using mixtures of extremely persistent chemicals on potentially hundreds of millions of acres of US land every year is, to us, a cause for concern.â The commentary, titled âForever Pesticides: A Growing Source of PFAS Contamination in the Environment,â explores how and to what extent PFAS […]

(Beyond Pesticides, April 24, 2024) On April 16, 2024, the U.S. Environmental Protection Agency (EPA) posted an âupdateâ to the Draft Herbicide Strategy Framework (Draft Herbicide Strategy Framework to Reduce Exposure of Federally Listed Endangered and Threatened Species and Designated Critical Habitats from the Use of Conventional Agricultural Herbicides) that was released last summer, weakening aspects of the agencyâs efforts to âprotectâ endangered species from herbicide use. The update outlines three types of modifications to the Draft Strategy, including âsimplifyingâ its approach, increasing growersâ âflexibilityâ when applying mitigation measures, and reducing the mitigation measures required in certain situations. By reducing the stringency of the Strategy, advocates are again questioning EPAâs commitment to fulfilling legal requirements under the Endangered Species Act (ESA) or protecting endangered species and their habitats in the midst of an unprecedented rate of global extinction. ESA is celebrated as one of the most far-reaching conservation laws globally, credited with preventing the extinction of 99 percent of those species the government targets for protection, according to the U.S. Fish and Wildlife Service (USFWS). ESA establishes a framework to categorize species as âendangeredâ or âthreatened,â granting them specific protections. Under ESA, EPA is required to consult with relevant agencies […]

(Beyond Pesticides, April 17, 2024) With headlines drawing public attention to the contamination of drinking water after years of federal government neglect, the U.S. Environmental Protection Agency (EPA) announced on April 10 new standards to reduce public exposure to PFAS, or per- and polyfluoroalkyl substances, commonly referred to as âforever chemicalsâ because of their persistence. EPA has finalized a National Primary Drinking Water Regulation (NPDWR) for six PFAS, including PFOA and PFOS, which EPA has recognized have no safe level of exposure, regulating new chemicals for the first time since the 1996 amendments to the Safe Drinking Water Act (SDWA). PFAS persistence and bioaccumulation in humans, wildlife, and the environment is due to the strength of a resulting fluorineâcarbon atom bond. PFAS contamination of drinking water, surface and groundwater, waterways, soils, and the food supplyâamong other resourcesâis ubiquitous worldwide. PFAS is used in everyday products, including cookware, clothes, carpets, as an anti-sticking and anti-stain agent, in plastics, machinery, and as a pesticide. The action was welcomed by environmentalists and public health advocates as an important step but left many concerned that any level of exposure to these chemicals is unacceptable and critical of EPAâs ongoing failure to act despite years […]

(Beyond Pesticides, August 22, 2023) A U.S. Geological Survey (USGS) and National Park Service collaborative survey report finds a harmful mixture of pollutants, including pesticides, pharmaceuticals, caffeine, methylparaben, algal toxins, and fecal and parasitic bacteria, in Pipestone Creek at Pipestone National Monument in Minnesota, U.S.â adding to evidence of widespread pesticide contamination in waterways across the U.S. Pesticide contamination in waterways is historically commonplace. A 1998 USGS analysis revealed pesticides are commonly found in all U.S. waterways, with at least one pesticide detectable. Thousands of tons of pesticides enter rivers and streams around the US from agricultural and nonagricultural sources, which contaminate essential drinking water sources, such as surface water and groundwater. As the number of pesticides in waterways increases, it has detrimental impacts on aquatic ecosystem health, especially as some pesticides work synergistically with others to increase the severity of the effect. Reports like these are significant tools for determining appropriate regulatory action to protect human, animal, and environmental health. The survey collected water samples from Pipestone Creek, the pipestone quarries, and Winnewissa Falls, all of which are on the U.S. Environmental Protection Agencyâs (EPA) list of impaired waters for turbidity (reduced water clarity) and fecal coliform bacteria (E. coli). Turbidity and fecal coliform […]

(Beyond Pesticides, July 25, 2023) How can scientists fight the elimination of national pesticide data? More data! A new report surveys 58 academic institutions, nongovernmental organizations, government officials, and businesses to measure the scientific, educational, and policy use of the United States Geological Survey (USGS) Pesticide National Synthesis Project (PNSP), a database that is getting phased out by the current administration.  According to the report authors, Maggie Douglas, PhD, Bill Freese, Joseph G. Grzywacz, PhD, and Nathan Donley, PhD, the PNSP is the âmost comprehensive public description of pesticide use in U.S. agriculture.â Despite its widespread use across the government and 348 citations since 2010, the database has been degraded in recent years, including a shift from monitoring 400 pesticides to 72 pesticides in 2019. Moreover, starting in 2024, estimates of agricultural pesticide use will be released every five years (instead of annually). Advocates believe the loss of PNSP data could further hinder the ability to manage pesticide impacts on humans, agriculture, and the environment. These concerns are outlined in a letter to USGS and the Department of Interior, signed by more than 250 scientists. Beyond Pesticides extensively tracks USGS data and resulting findings to inform local and state […]

(Beyond Pesticides, July 19, 2023) A study in Environment International (August issue) by the United States Geological Survey (USGS) finds that almost half of U.S. tap water is contaminated with PFAS chemicals, with measured concentrations in both private wells and public water sources. Authors of the study âestimate that at least one PFAS could be detected in about 45% of U.S. drinking-water samples.â Although there are more than 12,000 different types of PFAS, only 32 are detectable by USGS lab tests, so 45% is likely a low estimate. Per- and polyfluoroalkyl substances (PFAS) are a group of chemicals found in a variety of common household products such as nonstick pans and stain resistant carpeting, as well as pesticides and biosolids used as fertilizer. Long-chain PFAS, such as PFOA and PFOS, are more widely known because of their high toxicity and controversial use in the past. Today, long-chain PFAS are often replaced with short-chain PFAS, as the latter are not as bioaccumulative; however, short-chained PFAS also pose a significant threat because they remain highly persistent in the environment. Past Beyond Pesticidesâ articles have described the prevalence of PFAS in products as well as their negative health consequences, including cancer, decreased fertility, […]

(Beyond Pesticides, June 15, 2023) The Supreme Courtâs recent ruling in Sackett v. Environmental Protection Agency (EPA) on the Clean Water Actâs jurisdiction dramatically limits the EPAâs ability to protect critical wetland ecosystems. On May 25, in a 5-4 majority decision, the Supreme Court ruled that EPA has authority to protect only âwetlands with a continuous surface connection to bodies that are âwaters of the United Statesâ in their own right.â Wetlands must appear âindistinguishableâ from larger waterways at a surface-level perspective. Wetlands next to a large waterway are no longer protected if they are separated by a manmade or terrestrial barrier. Water flows underground from upstream to downstream sources and exits the confines of its customary boundaries during periods of flooding, so to declare waterways distinct based merely on a surface-level perspective defies scientific understanding of ecosystem health. Critical Nature of Wetland Ecology The conservation of wetland ecology is critical to the health of our environment. The United States Geological Survey (USGS) states, âWetlands are among the most productive habitats on earthâ given their role in flood resilience, improvement in water quality, and coastal erosion control. Wetlands are essential nursery grounds for many species of fish and oases for […]

(Beyond Pesticides, May 1, 2023)Â The sheer number of different chemicals in the nationâs waterways and thus potential for toxic mixtures presents significant risks to health and the environment. However, the range of pesticides and the widespread contamination across the country would not be as fully uncovered without the work of the U.S. Geological Survey (USGS). Research conducted by USGS and the U.S. Environmental Protection Agency (EPA) on urban runoff across the country in 2019 found 215 of 438 sampled toxic compounds present in the water. The toxic soup in many U.S. waterways is unsustainable and threatens the foundation of many food chains. Imbalances in aquatic environments can ripple throughout the food web, creating trophic cascades that further exacerbate health and environmental damage. The data on water contamination has become one of the compelling reasons to abandon reliance on toxic chemicals in favor of organic land management to eliminate these threats. Tell Secretary of Interior Deb Haaland to expand USGS mapping of pesticide use and monitoring of waterways. Tell EPA Administrator Michael Regan that pesticides shown to contaminate rivers and streams must be banned. The USGS Water Resources Mission Area (WMA) researches pesticide use, trends in pesticide occurrence in streams, concentrations […]

(Beyond Pesticides, April 18, 2023) Health officials in France are alerting the public that a majority of drinking water samples tested by the government contain the presence of the highly toxic fungicide chlorothalonil. The findings highlight a stark divide between regulations and public health management in the European Union and United States. While EU member states have banned this chemical and are working to understand and address lingering effects, tens of millions of pounds of chlorothalonil continue to be sprayed throughout the U.S. annually. French officials say they conducted this research after researchers in Switzerland found evidence of the fungicide in drinking water. A few years ago, Swiss scientists released a report showing Evian bottled water, touted for its claims of purity, was found to contain measurable levels of chlorthalonil.  âThe fact that even the Evian springs in the French Alps, which are hardly affected by humans, contain pesticide residues is alarming and shows the far too careless handling of these substances,â Roman Wiget, president of the international drinking water association AWBR told the German-language Swiss weekly at the time. The EU banned uses of chlorothalonil in 2019, due to concerns over water contamination, the effects of such contamination on fish […]

(Beyond Pesticides, February 14, 2023) The waterways that flow into the Great Lakes are experiencing year-round pesticide contamination that exceeds benchmarks meant to protect aquatic life, according to research published in Environmental Toxicology and Chemistry by scientists at the U.S. Geological Survey (USGS). âWhat you use makes it into the water,â study coauthor Sam Oliver, PhD, told the Milwaukee Journal Sentinel. These data buttress growing calls from pesticide reform advocates that new laws are needed to protect the nationâs increasingly threatened waters. USGS scientists conducted their analysis on 16 tributaries that feed into the Great Lakes, including sites that correspond to urban, agricultural, and undeveloped land. Samples were taken at locations closest to the lake the tributary flowed into over a period of roughly one year from October 2015 to September 2016. Each sample was tested for 231 pesticides and their breakdown products. Researchers used aquatic life benchmarks set by the U.S. Environmental Protection Agency (EPA), and created a relative hazard index (RHI) for the study to evaluate whether specific sites should be prioritized for further protections. Â Across every sampled tributary, pesticides were found. Accordingly, 96% (190 out of 198) of samples taken contained pesticides or their breakdown products. […]

(Beyond Pesticides, February 1, 2023) Honey bee declines in the United States are âprimarily relatedâ to pesticide exposure, parasitic mites, and extreme weather conditions, research published by Penn State scientists have determined. Publishing the results in Scientific Reports, the researchers aim to provide a national overview of the range of factors harming bee colonies. “Some previous studies have explored several potential stressors related to colony loss in a detailed way but are limited to narrow, regional areas,â said study co-author Luca Insolia, PhD. âThe one study that we know of at the national level in the United States explored only a single potential stressor. For this study, we integrated many large datasets at different spatial and temporal resolutions and used new, sophisticated statistical methods to assess several potential stressors associated with colony collapse across the U.S.” The results reinforce calls from bee health advocates in the U.S. and around the world: eliminate toxic pesticide use, the lowest hanging fruit contributing to pollinator declines. In order to create a more comprehensive national overview, geographers, entomologists, and statisticians all participated in the study, reviewing publicly available data on colony health, land use, weather, and other environmental factors over a five-year period from […]

(Beyond Pesticides, June 4, 2021) The release of the most recent U.S. Geological Services (USGS) study of pesticide contamination of rivers on the U.S. mainland finds that degradation of those rivers from pesticide pollution continues unabated. USGS scientists looked at data from 2013 to 2017 (inclusive) from rivers across the country and offered these top-level conclusions: â(1) pesticides persist in environments beyond the site of application and expected period of use, and (2) the potential toxicity of pesticides to aquatic life is pervasive in surface waters.â Beyond Pesticides maintains that ultimately, water quality and aquatic organisms and their ecosystems will be fully protected from pesticides through a wholesale movement to organic land management practices. USGS undertakes periodic assessments of the presence and toxicity of pesticides in the countryâs surface waters under the agencyâs National Water-Quality Assessment Program. Recent news from these studies has not been good. In September 2020, Beyond Pesticides reported on another, related USGS survey, which found that nearly 90% of U.S. rivers and streams are contaminated with mixtures of at least five or more different pesticides. A March 2021 Beyond Pesticides Daily News article noted that USGS research demonstrated that, of 422 water samples taken from streams across […]

(Beyond Pesticides, October 27, 2020) The insecticide fipronil is more toxic to aquatic insects than previously thought, often present in U.S. waterways, and can trigger trophic cascades that disrupt entire aquatic ecosystems, finds new research published by the U.S. Geological  Survey (USGS). The data have important implications for waterways throughout the country, but particularly in the Southeast U.S. where the chemical was found at hazardous levels in over half of sampled steams. Despite the high quality of the findings by a U.S. government agency, pesticide regulators at the U.S. Environmental Protection Agency (EPA) do not adequately consider ecosystem-level effects when determining whether to register a pesticide. As a result, without public pressure on the agency, it is unlikely it will follow the science and take the action necessary to rein in use and safeguard the environment. Fipronil is a systemic pesticide that can travel through plant tissues and be expressed in its pollen, nectar, and dew droplets. Due to its systemic properties and similar toxicity profile, it is often targeted for restriction alongside the notorious neonicotinoid class of insecticides. Although fipronil is equally concerning, there is less data on the range of harm the chemical may cause. To better understand […]
