(Beyond Pesticides, December 4, 2020) Amid the maelstrom of national political news related to the recent election, and the Trump administration’s upcoming exit, comes a release of the Environmental Protection Agency’s (EPA’s) draft biological evaluation (BE) of glyphosate. The assessment indicates that use of this ubiquitous herbicide likely threatens nearly every animal and plant species on the U.S. list of threatened and endangered species — 93% of them, in fact. Chemical and Engineering News reports that the EPA announcement was made public only a few days after the agency also reported that atrazine (another commonly used and toxic herbicide) probably harms more than half of those species. Given the Trump EPA’s eagerness, during the past four years, to serve industry interests rather than protect human health, biodiversity, and functional ecosystems, the timing of this released evaluation during the so-called “lame duck” period is puzzling. Glyphosate is the active ingredient in many herbicides, including RoundupTM, Monsanto’s (now Bayer’s) ubiquitous and widely used weed killer; it is very commonly used with genetically modified companion seeds for a variety of staple crops, as well as for weed control on managed landscapes. These seeds are genetically engineered to be glyphosate tolerant. Glyphosate-based herbicides are the most […]

(Beyond Pesticides, December 2, 2020) PFAS (per and polyfluorinated alykyl substances) ‘forever chemicals’ are being detected in a commonly used mosquito pesticide known as Anvil 10+10, according to reporting from the Boston Globe based on independent testing from a watchdog group and state regulators. PFAS are a large family of nearly 5,000 chemicals that may never break down in the environment and have been linked to cancer, liver damage, birth and developmental problems, reduced fertility, and asthma. The chemicals already disproportionately contaminate people of color communities, and there is evidence they reduce the efficacy of vaccines. While many may be familiar with PFAS for its use in nonstick cookware, electrical wire insulation, personal care products, food packaging, textiles, and other consumer goods, its presence within an already toxic pesticide is alarming. Perhaps most concerning, neither the manufacturer nor regulators have a good understanding of how exactly PFAS chemicals made their way into pesticide products. “This is an issue that cuts to the core of what’s wrong with our federal system for regulating pesticides,” said Drew Toher, community resource and policy director at Beyond Pesticides. “The finding makes it imperative that EPA review and disclose full pesticide formulations before allowing the […]

(Beyond Pesticides, November 20, 2020) Many pet owners likely do not consider what is actually in the flea treatments they administer to their animals. That should change, and recent research demonstrates why. Scientists sampling rivers in England found extreme contamination with two neurotoxic pesticides commonly used in flea products for dogs and cats: fipronil and the neonicotinoid imidacloprid. In many instances, the concentrations in the waterways were far higher than accepted “safe” levels. Though these compounds are banned for agricultural uses in the United Kingdom (UK), risk assessment for them, as used on animals, has been minimal because of the assumption that the amounts used for veterinary treatments would mean far-less-significant environmental impact than might be expected with agricultural-scale use. This research out of the University of Sussex voids that assumption, and the researchers recommend “re-evaluation of the environmental risks posed by pet parasite products, and a reappraisal of the risk assessments that these products undergo prior to regulatory approval.”   Apart from being an active ingredient in flea treatments for pets, fipronil is used in insect baits, and in turf management and agriculture in the U.S. It is highly toxic to insects, including bees, to birds, and to aquatic invertebrates. […]

(Beyond Pesticides, November 13, 2020) The toxic herbicide dicamba is once again at the center of a larger story about states’ authority to regulate pesticides beyond federal dictates. The Trump EPA (Environmental Protection Agency) has just made it much harder for state regulations to be more protective than federal rules are. It did so via a footnote embedded in dozens of pages of regulatory documents related to EPA’s registration of three new dicamba products. Given conservatives’ long-standing lip service to “states’ rights,” this EPA’s thwarting of the wishes of individual states to respond to their respective circumstances could easily be regarded as an odd — though, during this administration, hardly singular — stance. This latest development underscores EPA’s continuing failures to protect people and the environment, and the increasing tension between centralized, federal regulation and more-local regulation, whether by states or smaller localities. For nearly 30 years, state regulators have used a Section 24 provision of FIFRA, the Federal, Insecticide, Fungicide and Rodenticide Act — the law that gives EPA authority to regulate pesticides — to establish specific restrictions, on use of federally registered pesticide products, that go beyond what EPA has mandated. The agency has long allowed states to add […]

(Beyond Pesticides, November 11, 2020) Neonicotinoid insecticides inhibit honey bee sleep cycles, leading to stress and population declines, according to research from Vanderbilt University, published in Scientific Reports. Although there is already ample evidence of the dangers these systemic insecticides pose to pollinators – as evidenced by recent bans in the European Union and Canada – this new line of investigation add further detail to the ongoing crisis in the pollinator world. “I was thinking about honey bee disappearances and it clicked—if pesticides are killing bees indirectly but we don’t know exactly how, maybe it’s because they’re getting physically lost,” said study coauthor Michael Tackenberg, PhD.  Scientists conducted the experiment using honey bees located on Vanderbilt’s campus, which does not use neonicotinoid insecticides. After returning from pollen collection, forager bees were captured at their hive entrance and moved into monitoring tubes, which were subsequently transferred to the lab. In the lab, scientists were able to control light and dark cycles, and exposed bees to levels neonicotinoids they would likely experience if foraging on contaminated flowers. Foraging bees were first exposed to light/dark at 12/12 cycles, followed by four days of complete darkness, at which time some bees were provided neonics, […]

(Beyond Pesticides, November 6, 2020) Beyond Pesticides joined health and environmental groups suing the U.S. Environmental Protection Agency (EPA) late last month over its decision to reapprove the endocrine disrupting herbicide atrazine with fewer protections for children’s health. Despite the chemical being banned across much of the world, EPA continues to make decisions that benefit chemical industry executives. “EPA’s failure to remove atrazine represents a dramatic failure of a federal agency charged with safeguarding the health of people, wildlife, and the environment,” said Jay Feldman, executive director of Beyond Pesticides. “We seek to uphold the agency’s duty to act on the science, in the face of viable alternatives to this highly toxic weedkiller.” It is not hyperbole, but in fact scientifically documented, that atrazine exposure “chemically castrates” frogs, impairs fish reproduction, and can result in birth defects and cancer in humans. EPA decision comes on the heels of a rash of industry-friendly decisions. Within the last month, the agency has finalized rules weakening farmworker buffer zone protections, reapproving dicamba use on genetically engineered crops, and reregistering some of the most toxic pesticides on the market. The lawsuit, filed in the Ninth Circuit Court of Appeals, contends that before reapproving atrazine, […]

(Beyond Pesticides, November 5, 2020) Research at the University of California San Francisco (UCSF) finds that pesticide exposure increases the risk of developing Parkinson’s disease (PD), regardless of whether disease onset is idiopathic (spontaneous) or genetic (GBA genetic risk variant). Although the exact etiology of PD remains unknown, epidemiological and toxicological research repeatedly identifies exposure to pesticides, as well as specific gene-pesticide interactions, as significant adverse risk factors that contribute to PD. Furthermore, this study, “Gene Variants May Affect PD Risk After Pesticide Exposure,” suggests that environmental triggers like occupational exposure to pesticides can prompt PD in individuals with or without the genetic precursor. This research demonstrates the importance of assessing disease etiology concerning occupational pesticide exposure, especially if disease triggers are overwhelmingly non-hereditary. Since not all individuals genetically predisposed to the disease develop PD, with only 10 to 15 percent of PD cases being genetic, government officials need to consider alternate etiological pathways that include environmental risk factors. Study researchers note, “‘Environmental exposures may have differential effects in different genotypes’ and may predispose people with PD to different symptom burden.”  Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans living with PD and about […]

(Beyond Pesticides, November 4, 2020) Despite a recent court ruling voiding the registration of drift-prone dicamba herbicides on genetically engineered (GE) cotton and soybeans, EPA has renewed  the registration of these chemicals. The court’s ruling stated that EPA, “substantially understated risks that it acknowledged and failed entirely to acknowledge other risks,” in regards to the herbicides XtendiMax and Eugenia (dicamba), produced by agrichemical corporations Bayer and BASF for their genetically engineered (GE) crops. In announcing the decision, Administrator Andrew Wheeler said the agency made its decision “[a]fter reviewing substantial amounts of new information, conducting scientific assessments based on the best available science, and carefully considering input from stakeholders.” Yet, it is evident that the most important stakeholders for EPA continues to be chemical corporations. The history of dicamba’s use in GE agriculture reveal this to be the case. In the mid-2010s, Bayer’s Monsanto developed new dicamba-tolerant seeds and received approval to sell them from the U.S. Department of Agriculture. EPA had not yet approved its corresponding herbicide, but nonetheless, Bayer’s Monsanto urged farmers to plant its seed, claiming they would increase yields. The results of this were predictable: farmers began to use older, unapproved dicamba formulations on their new GE […]

(Beyond Pesticides, October 28, 2020) This month the U.S. Environmental Protection Agency (EPA) finalized decisions allowing continued use of a range of highly toxic pesticides, including the herbicide paraquat, and the synthetic pyrethroid class of insecticides. The move has been met with stinging criticism from the health and environmental community, but the decisions come as no surprise. Continued allowance of hazardous pesticides is a result of a weak law, lax regulations, and an administration that has consistently refused to follow even deficient protections. “The EPA’s pesticide office has sunk to a despicable new low in allowing farmworkers, small children and the environment to be sacrificial pawns in the profit schemes of its friends in the pesticide industry,” said Nathan Donley, PhD, senior scientist at Center for Biological Diversity. “In rushing to reapprove these deadly chemicals, it’s ignored its own scientists and independent researchers, refused to protect human health and the environment, and shown itself to be the panting lapdog of a morally bankrupt industry.” EPA reregistered paraquat despite overwhelming evidence that the chemical cannot be used without ‘unreasonable adverse effects on the environment’ — the lackluster standard in federal pesticide law to which the agency is required to regulate a […]

(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 […]

(Beyond Pesticides, October 23, 2020) In central California, what promises to be a landmark series of lawsuits against Corteva (formerly DowAgroSciences), maker of the pesticide chlorpyrifos, is under way, spearheaded by the case Alba Luz Calderon de Cerda and Rafael Cerda Martinez v. Corteva Inc., et al. This first suit, brought by the parents of Rafael Cerda Calderon, Jr. on his behalf, charges that his lifelong disabilities were caused by chronic exposures to chlorpyrifos. The parents are suing for general damages, compensatory damages (due to Rafael, Jr.’s loss of earning capacity), medical care costs, and “punitive damages for the willful, reckless, and recklessly indifferent conduct of the Defendants” in intentionally hiding the dangers of their chlorpyrifos products from customers and the public. As with so many dangerous pesticides, absent effective federal regulation, states, cities, and other entities are taking action to protect people from this compound, and as in this case, individuals are seeking redress for harms suffered. Beyond Pesticides has long advocated for a ban on the use of chlorpyrifos because of the grave risks it poses. The case was filed in mid-September in California Superior Court, Kings County, and names not only Corteva, but also, the cities of Huron and Avenal, Woolf […]

(Beyond Pesticides, October 21, 2020) Women now account for one in four agricultural jobs in the United States, and these important workers face unique challenges to their health and well-being, as outlined by a report published by Boise State University scientists. Farmworkers, often immigrants, or from communities of color, are frequently referred to as ‘invisible’, despite the essential job they perform getting food to American’s dinner tables. With their struggle and plight outside of the view of mainstream news, it is critical that U.S, residents better understand the lives they lead, and their daily obstacles, to inform how their conditions can be improved. “In this study, we tried to understand the women that we were working with what their concerns were and what their challenges were rather than coming in and just saying what we thought the concerns were,” Cynthia Curl, PhD, Associate Professor at Boise State University, told Idaho News 6 (IN6). To better assess the well-being of women farmworkers, researchers conducted mixed method data collection, through surveys, focus groups, and urinary analysis for pesticide body burden. Surveys were received from 70 Latina farmworkers, with 22 participating in focus groups and 11 in semi-structured interviews. An assessment of pesticide […]

(Beyond Pesticides, October 20, 2020) The additive stress of pesticide exposure and food scarcity leads to significant declines in wild pollinator populations, according to research published by scientists at University of California, Davis. Although it is well known that insect and pollinators populations are at risk from multiple stressors related to industrial agriculture, comprehensive evaluations are a challenging scientific undertaking. “Just like humans, bees don’t face one single stress or threat,” said lead author Clara Stuligross, a PhD. candidate in ecology at UC Davis. “Understanding how multiple stressors interplay is really important, especially for bee populations in agricultural systems, where wild bees are commonly exposed to pesticides and food can be scarce.” To better understand the interplay between these two stressors, researchers designed a field study. Mason bee pollinators were provided cages to nest in, and each stressor was separated out. One set of bees were provided high levels of food availability, while another received scant floral resources. Certain cages within each food level were treated with the product Admire Pro, a Bayer Cropscience insecticide containing the neonicotinoid imidacloprid. Scientists found significant impacts on the factors that deal with mason bees’ reproductive success. This includes the likelihood that a female […]

(Beyond Pesticides, October 15, 2020) A review of scientific literature on the correlation between respiratory diseases and pesticides exposure—published in the journal Annals of Agricultural and Environmental Medicine (AAEM), “Influence of pesticides on respiratory pathology—a literature review”—finds that exposure to pesticides increases incidents of respiratory pathologies (i.e., asthma, lung cancer, and chronic obstructive pulmonary disease [COPD]—or chronic bronchitis). The review by researchers at the Iuliu Hatieganu’ University of Medicine and Pharmacy Cluj-Napoca, Cluj-Napoca, Romania, looks at how pesticide exposure adversely propagates and reinforces respiratory diseases in humans. This review highlights the significance of evaluating how pesticide exposure impacts respiratory function, especially since contact with pesticides can happen at any point in the production, transportation preparation, or application treatment process. Researchers in the study note, “Knowing and recognizing these respiratory health problems of farmers and their families, and also of [pesticide] manipulators/retailers, are essential for early diagnosis, appropriate treatment, and preventive measures.” This study results are critically important at a time when exposure to respiratory toxicants increases vulnerability to Covid-19, which attacks the respiratory system, among other organic systems. The respiratory system is essential to human survival, regulating gas exchange (oxygen-carbon dioxide) in the body to balance acid and base tissue cells for normal […]

(Beyond Pesticides, October 14, 2020) Exposure to certain endocrine disrupting pesticides increases the risk men, and Hispanic men in particular, will contract testicular cancer, according to research presented at the American Association for Cancer Research Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved. The data show that living near the use of the insecticide acephate presents the greatest cancer risk. “Testicular cancer rates have been rising for decades and are rising especially quickly among Hispanics in the United States,” said Scott Swartz, an MD candidate in University of California Berkeley-UCSF Joint Medical Program, to Healio. “Given that Hispanics are disproportionately exposed to many endocrine-disrupting pesticides in California, we were interested in investigating the potential effects of nearby endocrine-disrupting pesticide application on testicular cancer among Hispanics in California.” Using public health databases, researchers assessed a group of 381 men diagnosed with testicular cancer while 15 to 19 years old, during the years 1997-2011. This cohort was compared to a control group of 762 otherwise healthy men of similar age, race and ethnicity during the same time. California’s Pesticide Use Report system was used to analyze agricultural pesticide applications within 1.8 miles of a study […]

(Beyond Pesticides, October 9, 2020) A new study demonstrates that emerging “novel” insecticides can cause significant, sublethal harm to beneficial organisms at typical “real life” exposure levels. As neonicotinoid insecticides have come under fire for their terrible impacts on a broad variety of beneficial insects — including their major contributions to the decline of critical pollinators — more such “novel” pesticides are being brought to market in response. The study results, the co-authors say, “confirm that bans on neonicotinoid use will only protect beneficial insects if paired with significant changes to the agrochemical regulatory process. A failure to modify the regulatory process will result in a continued decline of beneficial insects and the ecosystem services on which global food production relies.” Beyond Pesticides would add that the study outcome points, yet again, to the grave recklessness of the pervasive “addiction” to chemical pesticides in agriculture. The solution to this chemical morass is known, doable, and scalable: a transition to organic, regenerative agricultural practices that get everyone off the “toxic treadmill.” Neonicotinoid pesticides (neonics) are the class of chemical pesticides most commonly used worldwide, both on crops and as seed treatments. They are systemic, meaning they infiltrate all tissues of a […]

(Beyond Pesticides, October 8, 2020) Research from the University of Wisconsin—Madison (UWM), suggests that fludioxonil—a commonly used agricultural fungicide—decreases the human body’s ability to defend itself against illnesses, like COVID-19, and promotes disease permanency. Tristan Brandhorst, a Ph.D. scientist at UWM, notes that a pesticide-induced reduction in the antioxidant glutathione could be responsible for this lack of bodily defense against disease. Although many studies examine how pesticides adversely affect the human body (i.e., cancer, respiratory issues, etc.), very few studies assess how pesticides reinforce chemical disruption patterns that reduce levels of vital chemicals needed for normal bodily function. The steady rise in U.S. pesticide use, including disinfectants, threatens animals and humans, as exposure to indiscriminate dispersal of pesticides cause a whirlwind of health risks. As the total U.S. COVID-19 cases rise above 7.5 million, global leaders need to understand extensive pesticide spraying is not a viable solution to prevent illness and causes more chronic harm from exposure in the long run. Dr. Brandhorst stresses the need for proper reevaluation of pesticide risks stating, “The issue needs more study, [and] might also warrant a reworking of how [the U.S. Environmental Protection Agency] evaluates pesticides.” Amidst the outbreak of SARS-CoV-2 (COVID-19), the global demand […]

(Beyond Pesticides, October 7, 2020) This week the Baltimore, Maryland City Council passed an ordinance restricting the use of toxic pesticides on public and private property—including lawns, playing fields, playgrounds, children’s facility (except school system property [golf courses are exempt]—following an approach similar to legislation first spearheaded by Montgomery County, MD in 2015. While the legislation, 20-0495, An Ordinance Concerning Pesticide Control and Regulation, generally limits inputs to the allowed materials under federal organic law, it provides for allowances for glyphosate by the Department of  Recreation and Parks. If signed by the Mayor, as expected, Baltimore City will become the most recent Maryland jurisdiction to exercise its authority to regulate pesticide use on private property, after a ruling of the state’s highest court. Language in the Baltimore ordinance tracks a similar framework to the Healthy Lawns Act passed in Montgomery County, Maryland. Any pesticide that is not compatible with organic land care—allowed under certified organic by the U.S. Department of Agriculture (USDA) or considered minimum risk by the U.S. Environmental Protection Agency (EPA)—is subject to the bill’s restrictions. Use can only occur under limited exceptions, such as to manage particularly invasive species, as well as health or economic threats. Bee-toxic […]

(Beyond Pesticides, October 5, 2020)  Another example of trading health and environmental protection for the support of special interests, EPA announces the misleading and fraudulently named, “EPA Supports Technology to Benefit America’s Farmers.” This time, EPA announces plans to “streamline the regulation of certain plant-incorporated protectants (PIPs).” Named to sow confusion, PIPs are plants engineered with pesticides in them. PIPs are known in general for two problems arising from incorporating pesticidal ingredients into crops: residues that cannot be washed off and production of crop-eating insects that are resistant to the incorporated pesticide that blankets the agricultural landscape.  Tell Congress that EPA needs to listen to science, not pesticide manufacturers and biotech companies that are causing problems for farmers and the environment. This time, EPA is proposing to exempt from regulation certain PIPs created by biotechnological techniques that are cisgenic (using genes derived from sexually compatible species), such as CRISPR. The distinction that EPA seeks to make between cisgenic plants and transgenic plants (in which the gene of interest may come from any species) is not supported by science. In fact, cisgenic techniques make use of genetic material other than the targeted genes, and that may come from species that are not […]

(Beyond Pesticides, October 2, 2020) The U.S. Environmental Protection Agency’s (EPA) September 22 announcement asserts that, “despite several years of study, the science addressing neurodevelopmental effects [of the insecticide chlorpyrifos] remains unresolved,” as reported in The New York Times. This conclusion contradicts both ample scientific evidence and the agency’s own findings. Beyond Pesticides has repeatedly advocated for a ban on the use of chlorpyrifos because of the grave risks it poses. This organophosphate pesticide is used on approximately 60 different crops, including almonds, cotton, citrus fruits, grapes, corn, broccoli, sugar beets, peaches, and nectarines. It is also commonly employed for mosquito-borne disease control, and on some kinds of managed turf, including golf courses. Exposure to the pesticide has been identified repeatedly as problematic. Most residential uses were taken off the market in 2000, after the manufacturer, DowDupont (now Corteva) was faced with EPA action. Chlorpyrifos is a cholinesterase inhibitor that binds irreversibly to the receptor sites of acetylcholinesterase (AChE), an enzyme that is critical to normal nerve impulse transmission. In so doing, chlorpyrifos inactivates the enzyme, damages the central and peripheral nervous systems, and disrupts neurological activity. The compound is associated with harmful reproductive, renal, hepatic, and endocrine disrupting effects, and most […]

(Beyond Pesticides, October 1, 2020) A federal judge on September 24, 2020 dismissed an  environmental lawsuit seeking to reinstate a U.S. Fish and Wildlife Service (FWS) rule, killed by the Trump Administration, which banned the use of neonicotinoid insecticides, genetically engineered (GE) crops, and adopted a precautionary approach to pest management. The decision comes on the heels of a Center for Biological Diversity (CBD) analysis that reports a 34% increase in the pesticide use on U.S. national wildlife refuge acres over a two year period from 2016-2018. This analysis is an update to CBD’s 2018 report, No Refuge, which is the first of its kind to offer comprehensive details of agricultural pesticide spraying in national wildlife refuges. Wildlife refuges act as a sanctuary, providing habitat and protection essential for the survival and recovery of species nationwide. However, pesticide spraying in or around wildlife refuges threatens the survivability and recovery of species that reside there as many of these pesticides are highly toxic to human and animal health. Analyses like these are significant, especially since the globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one million species of plants and animals at risk of extinction. In 2012, […]

(Beyond Pesticides, September 30, 2020) Low doses of neonicotinoid (neonic) insecticides are known to disrupt insect learning and behavior, but new science is providing a better understanding of how these effects manifest at a cellular level. Published in the Proceedings of the National Academy of Sciences, this study finds that the neonic imidacloprid binds to brain receptors, triggering oxidative stress, reducing energy levels, and causing neurodegeneration. “Although many studies have shown that low doses of insecticides can affect insect behavior, they have not uncovered whether insecticides trigger changes at the cellular and molecular levels,” said lead author Felipe Martelli, PhD, of Monash University in Melbourne, Australia. “The goal of this work was to have a better understanding of the effects of low doses of the common insecticide imidacloprid at the cellular, physiological and behavioral levels.” Researchers used the fruit fly Drosophilia melanogaster, a common experimental organism, as it contains a number of nicotinic acetylchloline receptors, the primary site of action for imidaclorpid. The neonic binds to these receptors, which regulate a number of physiological processes, such muscle contraction. Binding closes these channels, leading to the range of harm researchers observed through their study. Larval fuit flies were exposed to imidacloprid […]

(Beyond Pesticides, September 24, 2020) A new report by the U.S. Geological Survey (USGS), National Water-Quality Assessment (NAWQA) Project, reveals the presence of pesticides is widespread in U.S. rivers and streams, with over almost 90 percent of water samples containing at least five or more different pesticides. Pesticide contamination in waterways is historically commonplace as 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 U.S. 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 a significant tool in determining appropriate regulatory action to protect human, animal, and environmental health. USGS concludes, “Identification of primary contributors to toxicity could aid efforts to improve the quality of rivers and streams to support aquatic life.” Water is the most abundant and important chemical compound on earth, essential to survival and the main component of all living things. Less than three percent of that water […]
