(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.— 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 Agency’s (EPA) list of impaired waters for turbidity (reduced water clarity) and fecal coliform bacteria (E. coli). Turbidity and fecal coliform […]

(Beyond Pesticides, August 23, 2023) Researchers are investigating a cutting-edge method to identify the impact of pesticides on reproductive health—shrinking the wait time from months to weeks. Scientists at the University of California, Davis, are developing a method for identifying harmful chemicals in pesticides with the help of glowing fish. This scientific breakthrough could revolutionize pesticide research and help prevent long-term health problems caused by exposure to these chemicals.  Pesticide exposure can cause acute and long-term health problems for the human endocrine system, the hormone system that regulates many biological processes from reproduction to blood sugar, growth, and more. Beyond Pesticides has written about the connections between EPA-registered pesticides and involuntary abortions, reproductive cancers, pregnancy loss, early-onset puberty, and more.   The American Academy of Pediatrics (AAP) has expressed concern over the limited or missing data regarding the health effects of pesticides and food additives on infants and children, who are more vulnerable to chemical exposures. AAP has identified several compounds as being of particular concern, including bisphenols, which are commonly used in the lining of metal cans; phthalates, which are used in adhesives and plasticizers; nonpersistent pesticides, which have been addressed in a previous AAP policy statement; perfluoroalkyl chemicals (PFCs), […]

(Beyond Pesticides, August 23, 2023) The use of pesticides on pets for fleas and ticks (parasiticides) has been traced to environmental contamination in a study that confirms earlier work both by the authors and internationally, according to researchers Rosemary Perkins, a veterinary surgeon, and David Goulson, PhD at the University of Sussex. The results are published in their recent study, “To flea or not to flea: survey of UK companion animal ectoparasiticide usage and activities affecting pathways to the environment,” which concludes that, “[T]he potential cumulative impact of parasiticide emissions [into the environment] from many millions of pets treated multiple times each year is of serious concern.” The UK provides an opportunity to pinpoint water contamination from pet use for ectoparasites (e.g., fleas and ticks) of hazardous pesticides since, unlike in the U.S., the country has banned outdoor use of those chemicals commonly detected—the insecticides fipronil and imidacloprid (the same neonicotinoid bug killer tied to devastating losses of bees and other organisms). These findings confirm the historical peer reviewed scientific literature and defy the assumption of regulators that home or veterinary use of pesticides do not reach levels of concern for environmental contamination, either through exposure from down-the-drain (DTD) contamination […]

(Beyond Pesticides, August 4, 2023) The results of an Australian study published in Nature strike a contrast between land and water contamination with pesticide active substances (PAS), highlighting contamination as pesticides are transported through waterways.  The study results on water transport raise serious contamination issues. Only about one percent of the pesticides entering rivers degrade, so that long stretches of waterways and the oceans suffer the direct impact of a pesticide’s active ingredient. The lack of degradation also means that water organisms are being exposed to levels of pesticides exceeding many of the regulatory threshold limits set by governments. Although observation data are highly variable, the authors note that measured concentrations of pesticides in some river reaches of North America, East Asia and Europe exceed one or more regulatory threshold limits “at least once a year.” Further, the pesticides can bioaccumulate at each level of the aquatic food web, which can multiply concentrations by a thousand or more in the highest trophic levels, according to the study authors. The study finds that more than four-fifths of PAS are degraded in the soil, leaving about 10 percent of the original chemical in the soil as residue. Nearly half of that residues […]

It’s hard to escape the impacts of the Barbie movie’s estimated $150 million marketing campaign. You may have noticed advertisements with Burger King’s pink burgers to Airbnb’s Barbie Dreamhouse. Perhaps you have seen viral memes or news stories about the movie’s takedown of the patriarchy or critiques that the movie is overly woke. The pink symbol of Barbie is often followed by a second symbol — plastic. The total mass of plastics on Earth now doubles the total mass of all living mammals, so would Barbie say life is fantastic? Or, might she urge the National Organic Standards Board to ban plastic mulch, an issue on the agenda at the Board’s upcoming October meeting? Plastic products, including those used in chemical-intensive and organic agriculture, and pesticides, play a seemingly necessary role in modern life, encompassing many items beyond straws and grocery bags. However, the convenience of plastic comes at a considerable cost to the planet and human health. The majority of plastics are manufactured using oil and gas, exacerbating climate change. Scientists are becoming increasingly alarmed by the repercussions of microplastics, which are plastic particles smaller than 5 mm in size. In 2022, Philip Landrigan, M.D., et al., announced the […]

(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 “estimate that at least one PFAS could be detected in about 45% of U.S. drinking-water samples.” 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 Pesticides’ articles have described the prevalence of PFAS in products as well as their negative health consequences, including cancer, decreased fertility, […]

(Beyond Pesticides, July 18, 2023) The Global Environment Facility (GEF) Council, the governing body for the world’s largest source of multilateral funding for biodiversity loss and climate change, has authorized $34 million USD to support the new high seas treaty agreement announced on March 4. The move marks a significant step toward safeguarding the delicate ecosystems of the world’s oceans and promoting sustainable practices on a global scale. The oceans suffer from severe pollution caused by various substances, including pesticides, agricultural runoff, industrial and petrochemical waste, and synthetic chemicals found in plastics. These pollutants pose a significant threat to human health. The ecological consequences of ocean pollution have long been highlighted by Beyond Pesticides. The March draft agreement was approved by 193 countries under the United Nations Convention on the Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction (BBNJ). Then in June, the BBNJ agreement was adopted by consensus at the United Nations meeting in New York. The agreement will be open for countries to sign on September 20, 2023, after the Sustainable Development Goal Summit. In order for the treaty to be entered into force, sixty countries must […]

(Beyond Pesticides, June 29, 2023) In the first major settlement amid an influx of PFAS litigation, industrial chemical giants DuPont, Chemours, and Corteva will pay $1.185 billion dollars to cities and towns across the U.S. to cover the cost of PFAS remediation and monitoring in public drinking water systems. The significance of this nationwide class-action settlement cannot be overstated, as citizens have battled powerful chemical corporations for decades with limited success. Dangerous toxicants have been indiscriminately discharged into the environment by chemical companies since the mid-1900s, and the PFAS litigation is important in the company’s acceptance of responsibility for contamination. Of course, the damage to health and the environment is incalculable, given the pervasive environmental contamination and poisoning that it has caused, and additional lawsuits are pending, with more expected. Advocates maintain that this case exemplifies the inadequacies of regulatory controls that do a poor job of capturing the long-term effects of chemicals before being introduced into the market and a worse job of questioning the essentiality of toxic substances for which there are alternative practices and products. PFAS bring into sharp focus the legacy of chemical contamination and the impact on  future generations—a problem well-documented with pesticides like DDT […]

(Beyond Pesticides, June 15, 2023) The Supreme Court’s recent ruling in Sackett v. Environmental Protection Agency (EPA) on the Clean Water Act’s jurisdiction dramatically limits the EPA’s 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 “wetlands with a continuous surface connection to bodies that are ‘waters of the United States’ in their own right.” Wetlands must appear “indistinguishable” 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, “Wetlands are among the most productive habitats on earth” 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) The sheer number of different chemicals in the nation’s 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.  “The 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,” 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, March 10, 2023) Following years of discussions and negotiations, 193 United Nations member countries have just approved — for the first time — a draft treaty for protection of the globe’s “high seas” and their denizens. The March 4 adoption of the draft marks the achievement of a potential legal framework for such protections, but is also the beginning of “a long journey to ensure the world’s oceans are adequately protected for future generations,” according to coverage by NewScientist. As research out of Boston College identifies, our oceans are badly polluted by multiple substances — including pesticides and other agricultural runoff; industrial and petrochemical waste; and the synthetic chemicals embedded in plastics — that threaten human health. The treaty, which must be adopted by member states and then ratified by at least 60 countries to take effect could be a critical development for meeting the COP15 “30 by 30” goal of protecting 30% of the world’s land and sea by 2030 to slow and arrest global biodiversity losses. Beyond Pesticides has long covered the ecological harms of ocean pollution.  The treaty represents a step toward implementation of President Biden’s 2021 “America the Beautiful Initiative,” proclaiming “the first-ever national conservation goal” established […]

(Beyond Pesticides, February 21, 2023) The recent train derailment in East Palestine, Ohio, should be a reminder to all of us that problems with our reliance on toxic chemicals go beyond broadcasting them on fields. In order to get pesticides to their point of use, toxic precursors and ingredients must be transported. Toxic waste products are also delivered to a location where they may be burned or deposited in a landfill. In weighing the hazards of toxic pesticides, these ancillary hazards should also be considered. Tell EPA and Congress that all impacts of toxic chemicals—from cradle to grave—must be considered before allowing their use.      The freight train that derailed February 3, 2023 in East Palestine was carrying a number of toxic chemicals. EPA notified the railroad, “EPA has spent, or is considering spending, public funds to investigate and control releases of hazardous substances or potential releases of hazardous substances at the Site. Based on information presently available to EPA, EPA has determined that Norfolk Southern Railway Company (Norfolk Southern or “you”) may be responsible under CERCLA [Comprehensive Environmental Response, Compensation, and Liability Act–Superfund] for cleanup of the Site or costs EPA has incurred in cleaning up the Site.” But […]

(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). “What you use makes it into the water,” 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 nation’s 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.   Across every sampled tributary, pesticides were found. Accordingly, 96% (190 out of 198) of samples taken contained pesticides or their breakdown products. […]

(Beyond Pesticides, December 6, 2022) Persistent organic pollutants (POPs)—including banned pesticides—present a health risk to humpback whales (Megaptera novaeangliae), according to a study published in Environmental Pollution. Regarding female humpback whales, levels of POPs in blubber are higher in juveniles and subadults than in adults, primarily from the transference of contaminants from the mother to her calf.  Organochlorine compounds (OCs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are well-known persistent organic pollutants. The international Stockholm Convention treaty (signed by 152 countries, but not the U.S.) banned these primary pollutants of concern (UNEP, 2009) in 2001 (taking effect in 2004) because of their persistence, toxicity, and adverse effects on environmental and biological health. These pollutants have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. However, these chemicals can remain in the environment for decades and interact with various current-use pesticides, including organophosphates, neonicotinoids, and pyrethroids. Although various studies demonstrate the volatile, toxic nature of POPs, much less research evaluates the impact POPs have on maternal offloading or transfer of contaminates to offspring and respective health consequences. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one […]

(Beyond Pesticides, December 5, 2022) A petition filed last week with the U.S. Fish and Wildlife Service (USFWS) urges increased protections for the West Indian manatee after dramatic declines in its population over recent years. In 2017, USFWS downgraded the classification of the manatee from endangered—a category that broadly protects against “take,” defined as “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct”—to threatened, for which an “acceptable” level of “take” is allowed. Following the downlisting of the species, manatee populations have declined dramatically. Tell the U.S. Fish and Wildlife Service to upgrade the Florida manatee to endangered and require protection from chemical pollution. Tell your Congressional Representative to cosponsor H.R. 4946 and your Senators to introduce identical legislation. Tell Florida’s Fish and Wildlife Conservation Commission to protect manatees. Florida manatees, a subspecies of the West Indian manatee (Trichechus manatus), can live as long as 60 years, weigh up to 1,200 lbs, and have no natural predators. The biggest threat to these peaceful marine mammals is human activity. Humans harm manatees directly through boat strikes and encounters with fishing equipment, canal locks, and other flood control structures, but the largest threat […]

(Beyond Pesticides, October 4, 2022) A study published in Environmental Pollution finds pyrethroid insecticides contribute to a secondary source of contamination in water resources. Various pyrethroids, including bifenthrin, are detectable in urban catch basins (storm drains) that collect runoff water before draining into the open environment. There is a lack of information regarding the pesticides’ presence in urban catch basins. However, pesticide contamination in water resources is historically commonplace and widespread throughout U.S. rivers and streams, with at least five different pesticides present in 90 percent of water samples. Moreover, thousands of tons of pesticides not only enter waterways (e.g., rivers, streams, lakes, oceans) around the U.S. through urban catch basins but agricultural and nonagricultural sources as well, contaminating essential drinking water sources, such as surface water and groundwater. Reports like these are essential for determining appropriate regulatory action to protect the human, animal, and environmental health from chemical toxicant contamination, especially if chemical contamination is highly detectable. The study notes, “The high detection frequency of bifenthrin and overall pyrethroid concentrations, especially for particle-bound residues, suggest that underground urban catch basins constitute an important secondary source for extended and widespread contamination of downstream surface waters by pesticides such as pyrethroids in urban […]

(Beyond Pesticides, September 14, 2022) The U.S. Environmental Protection Agency (EPA) is confirming that PFAS (per and polyfluorinated alykyl substances) forever chemicals leach into pesticides from their storage containers, and is taking steps to remove 12 “inert” PFAS ingredients that are currently allowed to be added to pesticide products. The agency’s move is a step toward some measure of health protections from chemicals that may have been widely sprayed throughout many American communities, and have been linked to cancer, liver damage, birth and developmental problems, reduced fertility, and asthma. However, many advocates indicate EPA’s actions on PFAS inerts do not go far enough, and the agency’s findings regarding leaching storage containers are accompanied by no meaningful restrictions on their use. Following reports and preliminary testing conducted in 2020 showing that PFAS chemicals are present in a widely used mosquito adulticide, EPA began investigating the source of this contamination. Testing on the product Anvil 10+10, produced by the company Clarke, resulted in detection of nine different PFAS chemicals. Early indications indicate that the high-density polyethylene (HDPE) containers used to store pesticides contained PFAS substances on their walls, and that those chemicals are leaching into the liquid pesticides stored in contaminated barrels. These […]

(Beyond Pesticides, August 31, 2022) No rainwater on Earth is safe for consumption and use as per-, and poly-fluoroalkyl substances (PFAS) readily contaminate the hydrological ecosystem (properties, distribution, and circulation of water), according to a study published in Environmental Science and Technology. This finding is concerning as it adds to research demonstrating chemical pollutants (e.g., pesticides, pharmaceuticals, PFAS, heavy metals, radioactive material, etc.) exceed the “planetary boundary” contamination and needs addressing. The Stockholm Resilience Centre, Stockholm University study, “Planetary Boundaries: Exploring the Safe Operating Space for Humanity,” emphasizes that there are nine “planetary boundaries” related to climate change, biodiversity loss, the nitrogen cycle, the phosphorous cycle, stratospheric ozone depletion, ocean acidification, global freshwater use, changes/intensification of land use, atmospheric aerosol loading, and chemical pollution. When crossing these boundaries, the risk of generating large-scale abrupt or irreversible environmental changes increases. In fact, anthropogenic (human) activities are increasing global contamination levels past safe thresholds. Studies have already found that current human operations are quantifiable in almost all nine planetary boundaries and exceed the threshold for at least four out of the nine boundaries. Most recently, a 2022 report concludes that humanity exceeds planetary boundaries related to environmental pollutants and other “novel entities,” including plastics and pesticides. […]

(Beyond Pesticides, August 17, 2022) Health and environmental advocates are urging Governor Kathy Hochul (D) to sign into law legislation that allows localities in the state to protect freshwater wetlands from toxic pesticide applications. The legislation, SB S8378C, sponsored by Senator Pete Harckham (D-WF) and passed by the state Senate and Assembly, represents an important affirmation of the local democratic right of communities seeking to protect their residents and local environments from hazardous pesticides. The state-level legislation comes at a time when local communities are under attack from pesticide industry allies in Congress, who are promoting legislation to “preempt” or prohibit states from enacting these laws, and localities from exercising their right to local control. The bill is awaiting the governor’s signature. Underlying Senator Harckham’s legislation is the principle that local communities should be able to set rules to protect their drinking water from contamination. Local officials, Sen. Harckham notes, know their wetlands and aquifer systems best. “Pesticides and herbicides should not have blanket application if a municipality chooses to regulate their local wetlands that way,” he told Spectrum News 1. Under the proposed legislation, a locality may enact pesticide restrictions only if the local government has already implemented a […]

(Beyond Pesticides, July 28, 2022) A report published in Chemosphere finds organophosphate (OP) insecticides readily contaminate drinking water resources, threatening human, animal, and ecological health. OPs have a wide range of biological uses—from insecticides to flame retardants—that make these chemicals ubiquitous, significantly contributing to ecosystem contamination. These compounds have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. OPs are highly toxic, and residues are consistently present in human and animal blood, urine, tissues, and milk. Considering 90 percent of Americans have at least one pesticide compound in their body, primarily stemming from dietary exposure, including food and drinking water, advocates maintain that current restrictions on their use must adequately detect and assess total chemical contaminants.  Water is the most abundant and crucial chemical compound on earth, essential to survival, and the main component of all living things. Less than three percent of that water is freshwater, and only a fraction of that freshwater is groundwater (30.1%) or surface water (0.3%) readily available for consumption. However, ubiquitous pesticide use threatens to reduce the amount of available freshwater as pesticide runoff, recharge, and improper disposal tends to contaminate adjacent waterways, like rivers, streams, lakes, or underground watersheds. With rivers and streams only accounting […]

(Beyond Pesticides, July 22, 2022) A preliminary report on two years of water sampling from sites in the Atlantic Ocean near the United Kingdom (UK), by a team from the Global Oceanic Environmental Survey Foundation (GOES), suggests that plankton populations may have plummeted by 90% since baseline 1940 levels. Just as insects are crucial as the basis of terrestrial ecosystems, plankton are the base of aquatic and marine food chains. As reported by Scotland’s Sunday Post, the reasons include chemical pollution in the ocean from plastics, synthetic fertilizer runoff, and pharmaceuticals. Beyond Pesticides adds that intensive use of synthetic pesticides also contributes to inhospitable conditions for the variety of plankton in our oceans. The researchers warn, “An environmental catastrophe is unfolding. We believe humanity could adapt to global warming and extreme weather changes. It is our view that humanity will not survive the extinction of most marine plants and animals.” The GOES website asserts, “The story that appeared on the front page of the Sunday Post was based on research and reports from www.GoesFoundation.com. We have just completed the largest Citizen Science project to map microplastic as well plankton productivity across the equatorial Atlantic. The results were so bad, we released an […]

(Beyond Pesticides, June 28, 2022) There is a strong connection between pesticide use and cancer rates in the Western United States, finds research recently published by scientists at University of Idaho and Northern Arizona University. Two studies (here and here) published in the peer-reviewed journal GeoHealth used geospatial data and publicly available pesticide databases to uncover the relationship between chemical heavy agricultural practices and cancer in both adults and children. As the rate of chronic diseases like cancer continue to increase in the United States, and more and more studies find these diseases to be pesticide-induced, it is imperative for the public to put increased pressure on regulators and lawmakers to enact meaningful measures that eliminate pesticide use and the hazards these chemicals pose. Of the two studies conducted by the research team, the first study modeled the connection between pesticide use and cancer incidence for adults and children in 11 western states (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming), while the second study focuses on childhood cancer rates in Idaho’s 44 counties. Both studies utilized databases established by public entities, including U.S. Geological Survey (USGS) Pesticide National Synthesis Project database, EPA Pesticide Industry […]
