(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, March 10, 2023) Following years of discussions and negotiations, 193 United Nations member countries have just approved â for the first time â a draft treaty for protection of the globeâs âhigh seasâ 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 âa long journey to ensure the worldâs oceans are adequately protected for future generations,â according to coverage by NewScientist. As research out of Boston College identifies, our oceans are badly polluted by multiple substances â including pesticides and other agricultural runoff; industrial and petrochemical waste; and the synthetic chemicals embedded in plastics â 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 â30 by 30â goal of protecting 30% of the worldâs 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 Bidenâs 2021 âAmerica the Beautiful Initiative,â proclaiming âthe first-ever national conservation goalâ 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 chemicalsâfrom cradle to graveâmust 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, âEPA 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 âyouâ) may be responsible under CERCLA [Comprehensive Environmental Response, Compensation, and Liability ActâSuperfund] for cleanup of the Site or costs EPA has incurred in cleaning up the Site.â 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). 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, December 6, 2022) Persistent organic pollutants (POPs)âincluding banned pesticidesâpresent 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, Earthâs 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 endangeredâa category that broadly protects against âtake,â defined as âto harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conductââto threatened, for which an âacceptableâ level of âtakeâ 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 pesticidesâ 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, âThe 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 âinertâ PFAS ingredients that are currently allowed to be added to pesticide products. The agencyâs 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 EPAâs actions on PFAS inerts do not go far enough, and the agencyâs 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 âplanetary boundaryâ contamination and needs addressing. The Stockholm Resilience Centre, Stockholm University study, âPlanetary Boundaries: Exploring the Safe Operating Space for Humanity,â emphasizes that there are nine âplanetary boundariesâ 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 ânovel entities,â 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 âpreemptâ 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 Harckhamâs 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 usesâfrom insecticides to flame retardantsâthat 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 Scotlandâs 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, âAn 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.â The GOES website asserts, âThe 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 Idahoâs 44 counties. Both studies utilized databases established by public entities, including U.S. Geological Survey (USGS) Pesticide National Synthesis Project database, EPA Pesticide Industry […]

(Beyond Pesticides, June 16, 2022) Farmed salmon serves as an inferior food source, accumulating more toxic chemicals in fatty tissue with fewer healthy nutrient properties based on a study from the University of Bergen, Norway and Alternative Medicine Review. However, the issue of toxic chemical contamination in fish dates back decades with investigations demonstrating high levels of persistent organic pollutants (POPs), including polybrominated diphenyl ethers (PBDEs) flame retardants restricted or banned in the U.S. and U.K., polychlorinated biphenyl (PCBs), dioxin (a by-product of pesticide manufacturing), and ethoxyquin (a pesticide preservative in fish feed). The aquaculture industry (e.g., farmed seafood/fish) repeatedly faces sustainability issues, failing to adhere to environmental regulations and threatening marine health. Extensive use of pesticides in local marine ecosystems has induced coastal habitat loss and increased genetic and health risks to wild marine populations. Moreover, insecticides used to kill salmon parasites (e.g., fish lice) has led to widespread disease persistence and pest resistance. Marine species biodiversity is rapidly declining due to overfishing, global warming, pathogens, and pollution. Thus, further biodiversity loss can change aquatic and terrestrial ecosystem functions and reduce ecosystem services. Food analysis results find the consumption of farmed salmon fillets contributes to higher rates of metabolic disorders, including diabetes and obesity. These farmed salmon also contain levels […]

(Beyond Pesticides, April 12, 2022) A recent study published in Scientific Reports warns that parasitic salmon lice (Lepeophtheirus salmonis) in Pacific Ocean open-net fish farming operations are becoming resistant to emamectin benzoate (EMB), an active ingredient used to control salmon lice population in North America, both in the U.S. and British Columbia, Canada. Previously, researchers believed parasitic salmon lice only had high rates of chemical resistance in the Atlantic region due to the mixing of farmed and wild salmon. However, Pacific salmon lice are exhibiting similar rates of decreased sensitivity to EMB from various sources, including a decrease in the wild Pacific salmon population, overuse of chemical treatments, and reliance on single chemical treatments. The aquaculture industry (e.g., farmed seafood/fish) repeatedly faces sustainability issues, failing to adhere to environmental regulations and threatening marine health. Extensive use of pesticides to rid the parasite has led to widespread resistance to multiple pesticides, prompting increasing infection rates among North Atlantic salmon populations. These parasites endanger both farmed salmon and wild salmon, in addition to other local species of fish. In this context, pesticide treatments contributes to resistance among lethal pest populations, especially in ecologically vulnerable and interconnected ecosystems like ocean basins. The researchers caution, âSalmon […]

(Beyond Pesticides, February 17, 2022) Reusable plastic sports bottles can leach hundreds of different chemical substances into water, including a range of plasticizers, endocrine disruptors and surprisingly, an insect repellent. Researchers at University of Copenhagen, Denmark recently published their findings in the Journal of Hazardous Materials, calling for caution in the use of these products. “We were taken aback by the large amount of chemical substances we found in water after 24 hours in the bottles. There were hundreds of substances in the water â including substances never before found in plastic, as well as substances that are potentially harmful to health. After a dishwasher cycle, there were several thousand,” says Jan H. Christensen, PhD, Professor of Environmental Analytical Chemistry at the University of Copenhagenâs Department of Plant and Environmental Sciences. Scientists used three types of reusable plastic sports bottles, split between newly purchased and bottles that had been in regular use before the experiment. Glass bottles were used as a control. First a migration experiment was conducted. Newly purchased bottles were rinsed with tap water (which was then disposed), and then refilled with tap water and stored for 24 hours. A second experiment placed all the bottles in the […]

(Beyond Pesticides, January 27, 2022) Wildlife officials in Florida have resorted to supplementing starving manatees with cabbage and lettuce in an attempt to keep their rapidly dwindling populations alive. Massive Red Tides exacerbated by runoff from urban and agricultural pollution have directly killed off dozens of manatees over the last several years, but the indirect effects of these harmful algae blooms have been most catastrophic, resulting in significant loss of the seagrass beds upon which manatees rely. While Florida Governor Ron DeSantis has announced plans to spend $481 million on water quality improvement projects, conservationists note that the funds are primarily directed toward point source wastewater treatment, and more is needed to address nonpoint source herbicide and fertilizer runoff from agricultural, and urban and suburban yards. Florida manatees, a subspecies of the West Indian manatee, can live as long as 60 years old, weigh up to 1,200 lbs, and have no natural predators within their range. The biggest threat to these peaceful marine mammals is human activity and environmental stressors. Unfortunately, the former is well-known to exacerbate the latter. Humans harm manatees primarily through boat strikes, but the animals can also die from eating or becoming entangled in fishing equipment, […]

(Beyond Pesticides, January 4, 2021) Chronic exposure to pesticides used in conventional forestry operations runoff and harm soft shell clams, according to a recent study published in Science of the Total Environment, entitled âThe silence of the clams: Forestry registered pesticides as multiple stressors on soft-shell clams.â Rather than focusing on the impact of a single chemical, researchers analyzed the combined effects of several pesticides. âThis is an important data gap to fill as research on these compounds’ toxicity typically focuses on individual compound effects at high concentrations to determine lethality, which while necessary for understanding compound toxicity, can miss sublethal effects that can have long term impacts on these systems,â said lead author Allie Tissot of Portland State University. The soft shell clam, Mya arenaria, is found to be widespread in coastal areas in both the western and eastern U.S., and is often eaten in stews or chowders. A recent study found a range of chemical contaminants detected in Oregon populations of these species, prompting researchers to further investigate the impact of these exposures. An experiment was set up with tanks to mimic a seabed, and eight different groups of 11 clams were established and treated with various amount […]

(Beyond Pesticides, November 8, 2021) California state agencies, led by the California Natural Resources Agency (CNRA), released a draft Natural and Working Lands Climate Smart Strategy to guide and accelerate near- and long-term climate action across key California landscapes. All states need such strategies, and to be effective, they must be backed by ambitious targets focused on reduction of pesticides and support for organic agriculture. Tell your state legislators and governor to adopt a Natural and Working Lands Climate Smart Strategy that supports organic agriculture and land management. (CALIFORNIA RESIDENTS: Please use this form.) A Natural and Working Lands Climate Smart Strategy will identify our natural and working lands as a critical yet currently underutilized sector in the fight against climate change. These lands can sequester and store carbon emissions, limit future carbon emissions into the atmosphere, protect people and nature from the impacts of climate change, and build resilience to future climate risks. Climate smart management of our natural and working lands also improves public health and safety, secures our food and water supplies, and increases equity. The strategy should define the stateâs natural and working landscapes; describe how these lands can deliver on climate change goals; highlight priority nature-based climate […]

(Beyond Pesticides, October 7, 2021) The Arizona State Auditor General reports a lack of groundwater monitoring for pesticides and other contaminants by the Arizona Department of Environmental Quality (ADEQ). For over six years, the agency failed to monitor groundwater and soil for agricultural pesticide contamination. Furthermore, the agency did not implement key groundwater monitoring processes over four years, despite law requirements. This lack of waterway monitoring resulted in an increased number of impaired surface waters across the state.  Pesticide contamination in waterways is historically commonplace and widespread throughout U.S. rivers and streams, with at least five or more different pesticides present in 90 percent of water samples. Thousands of tons of pesticides enter waterways (e.g., rivers, streams, lakes, oceans) around the U.S. from agricultural and nonagricultural sources, contaminating essential drinking water sources, such as surface water and groundwater. Reports like these are essential in determining appropriate regulatory action to protect human, animal, and environmental health from chemical toxicant contamination. The report states, â[The] Department has not developed all required aquifer water quality standards, conducted key ongoing groundwater monitoring of the Stateâs aquifers, monitored for agricultural pesticides in groundwater and surrounding soil, or reduced the number of impaired surface waters in the State, limiting its […]

(Beyond Pesticides, September 15, 2021) Toxic pesticide use, and glyphosate in particular, degrades the health of freshwater ecosystems by harming species that form the basis of aquatic food chains, according to research published by scientists at McGill University. In a series of studies, scientists investigated how freshwater bacteria and zooplankton were affected by varying levels the weed killer glyphosate, the neonicotinoid insecticide imidacloprid, and nutrient levels. âBecause plankton form the foundation of the food chain in freshwater ecosystems, it is very important to understand how plankton communities respond to widely used pesticides,â said Jesse Shapiro, PhD, an Associate Professor in McGillâs Department of Microbiology and Immunology. âOur research shows that the structure of these communities can be impaired under currently acceptable North American water quality guidelines.â Two separate experiments were conducted under similar conditions in order to properly investigate the effects of pesticide exposure on either zooplankton or freshwater bacteria. For both studies, target species were exposed to varying rates of glyphosate, imidacloprid, or both chemicals at either high or low water nutrient levels. Researchers conducted this study by establishing a series of outdoor experimental ponds, intended to mimic freshwater ecosystems by using Lake water and evenly distributing organisms throughout […]

(Beyond Pesticides, August 5, 2021) A recent report by Turtle Rescue of the Hamptons finds Long Island, New York turtles are experiencing higher rates of deadly aural abscesses or ear blisters from pesticide use. Previous research documents the role chemical exposure from environmental toxicants play in inner ear abscess formation among turtles. However, synergism (collaboration) between viral infection and toxic chemical exposure increases aural abscess instances. Considering these infections are taking a toll on the Long Island turtle population, government and wildlife officials must assess how chemical exposure promotes disease development to safeguard human, animal, and environmental health. Karen Testa, executive director of Turtle Rescue of the Hamptons, cautions, “I’m urging Long Islanders to think about how these pesticides are negatively impacting the natural world. Is your perfect green lawn worth the life of a turtle?” Aural abscesses are painful ear blisters that can grow as big as a golf ball. Medical intervention is necessary to remove abscesses from turtles and treat them with an antibiotic regimen to prevent death. Turtle Rescue facility workers report a staggering 50 percent of turtles currently within their care to have aural abscesses. The percentage of turtles with this diagnosis is much higher than in past years. […]
