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

(Beyond Pesticides, February 20, 2024) With health risks including developmental, metabolic, cardiovascular, and reproductive harm, cancer, damage to the liver, kidneys, and respiratory system, as well as the potential to increase the chance of disease infection and severity, per- and polyfluoroalkyl substances (PFAS) and their toxic trail of contamination in the environment is wreaking havoc with all life. The use of PFAS in industrial and commercial applications has led to widespread contamination of water and biosolids used for fertilizer, poisoning tens of millions of acres of land and posing a significant threat to the biosphere, public health, gardens, parks, and agricultural systems. Farmers and rural communities, in particular, bear the brunt of this contamination, as it affects their drinking water, soil quality, and livestock health.   Tell Congress that the Farm Bill must include the Relief for Farmers Hit with PFAS Act and the Healthy H2O Act to protect farmers and rural communities from PFAS contamination.  Led by Chellie Pingree (D-ME), U.S. Senators Tammy Baldwin (D-WI), and Susan Collins (R-ME), a bipartisan and bicameral bill—the Relief for Farmers Hit with PFAS Act—has been introduced to provide assistance and relief to those affected by PFAS. A second bill, the Healthy H2O Act, introduced by Representatives Pingree and David Rouzer (R-NC) and Senators Baldwin […]

(Beyond Pesticides, May 2, 2023) On April 20, the European Commission’s new rules on endocrine disrupting chemicals took effect. Called “Classification, Labelling & Packaging” (CLP), the rules create four new hazard categories for endocrine disruptors. The categories range from “suspected of causing” or “may cause” endocrine disruption in the environment to “suspected of causing” or “may cause” endocrine disruption in humans. After a transition period, users will have to indicate on labels and packaging if a substance falls into any of the hazard classes. All actors in the supply chain are obligated to provide the information to every downstream participant. The  new CLP rules, implementing a 2022 measure adopted by the European Commission and then the European Parliament, also specify a minimum font size for the hazard information and for the first time include standards for labeling in online commerce and in places where customers use refillable containers to transport, store, and use the chemicals. According to the EU Directorate-General for the Environment: “The new hazard classes are the result of extensive scientific discussions and will provide easier access to information to all users of such chemicals, notably consumers, workers and businesses. They allow further action to address and mitigate […]

(Beyond Pesticides, February 13, 2023) As more and more communities across the country outlaw pesticides on their public land, parks, and playing fields, most states prohibit (or preempt) localities from restricting hazardous use on private property. As a result, pesticides used on landscapes—uses that can be replaced by organic management practices—result in chemical drift and runoff, putting the community in harms way and people involuntarily exposed. The Protect America’s Children from Toxic Pesticides Act of 2023 (PACTPA), S.269, includes a provision that grants communities under federal pesticide law (the Federal Insecticide, Fungicide, and Rodenticide Act—FIFRA) local authority to restrict pesticides on all property, public and private, within their jurisdiction. While the U.S. Supreme Court (in Wisconsin Public Intervenor v. Mortier) in 1991 found that FIFRA does not preempt local governments’ authority to restrict pesticide use in their town, cities, or counties, state governments have taken that authority away in 44 states at the behest of the pesticide lobby. Urge your Senators to co-sponsor PACTPA and reforms to the toxic core of FIFRA, including upholding the right of local governments to restrict pesticides. As local governments debate the hazards associated with pesticide use in their communities, many have decided to transition their […]

(Beyond Pesticides, October 28, 2022) The Maine Congressional delegation — Senators Collins (R) and Angus King (I), and Representatives Chellie Pingree (D) and Jared Golden (D) — along with New Hampshire Senator Jeanne Shaheen (D), have introduced a bipartisan and bicameral bill — the Relief for Farmers Hit with PFAS Act — to help farmers who have been impacted by the scourge of PFAS (perfluoroalkyl and polyfluoroalkyl substances) chemicals. (The Senate version of the bill is available; the House version should be soon.) PFAS contamination has, as Beyond Pesticides documented in two Daily News Blog articles (here and here), become a huge, life-altering problem for agricultural producers in Maine and many other states. An early 2022 Safer States analysis of state-level legislation on PFAS demonstrated the extent of the problem via the response: more than 32 states have begun to act on the issue. Beyond Pesticides has covered the presence of PFAS in pesticides and pesticide containers, and in so-called “biosludge” or “biosolids”— realities that only reinforce the call for a rapid transition off of chemical-dependent agriculture and to regenerative organic agricultural practices that do not carry the enormous health and environmental risks of pesticide products and contaminated fertilizers. There […]

(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, 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, May 9, 2022) While the U.S. Environmental Protection Agency (EPA) updated its guidelines for pollinator risk assessments in 2014, the agency continues to either fail to conduct full assessments, or dismiss concerning data it receives. EPA appears to discount threats like the insect apocalypse, evidenced by a 75% decline in insect abundance, which threatens not only global ecosystems, but also food production that depends on animal pollination. As pesticides move through the food web, birds are also at risk. Bird numbers are down 29% since Rachel Carson wrote Silent Spring in 1962. Tell EPA To Protect Against Other Threats to Pollinators. Tell Congress To Insist that EPA Does Its Job. The problem is highlighted by EPA’s recent Interim Decision on fenbuconazole, in which the agency notes that, “For larval bees, RQs (risk quotients) exceed the LOC (level of concern) for all pollinator attractive uses including when assessed at the lowest application rate of 0.0938 lb a.i./Acre (RQ = 1.1).” Yet in the same document, the agency declares that “…the benefits of fenbuconazole (e.g., efficacy in management of fungal pathogens) outweigh any remaining risk and that continuing to register fenbuconazole provides significant benefits, including its ability to increase crop […]

(Beyond Pesticides, April 27, 2022) Pesticides can accumulate in aquatic fly larvae, be retained through metamorphosis, and represent a source of chronic pesticide exposure to birds and bats, according to research published in Environmental Science and Technology earlier this month. As population declines among these critical wildlife continue to mount, findings like these highlight the complex ways in which human activities are further stressing natural systems. Pesticide reviews conducted by the U.S. Environmental Protection Agency (EPA) are limited to an outdated set of studies conducted by the pesticide industry, and generally reject and dismiss emerging science from independent literature. This myopic focus on industry studies has brought widespread contamination to the natural world that necessitates wholescale changes at EPA through Congressional action. With widespread acknowledgement that older pesticide chemistries, such as organochlorines like DDT and aldrin, bioconcentrate in living organisms, researchers aimed their study at present use fungicides and herbicides that have not yet undergone similar scrutiny. This includes seven fungicides—azoxystrobin, boscalid, cyflufenamid, fluopyram, tebuconazole, pyrimethanil, and trifloxystrobin—and two herbicides—napropamide and propyzamide. The study notes that formulated end use products, rather than technical grade active ingredients, were used in order to best mimic real world exposure conditions. Larvae of the […]

(Beyond Pesticides, April 19, 2022) Both houses of Maine’s legislature have just approved a bill that would, by 2030, ban pesticides that contain PFAS chemicals — the so-called “forever chemicals.” The bill’s next stop is the Appropriations Committee, for approval of $200,000 in annual funding to enact the bill; if successful there, it will move to the desk of Maine Governor Janet Mills for her signature. The legislation is one of a suite of lawmaker efforts in the state to address the growing PFAS problem with which localities across the U.S. are struggling. In this Daily News Blog article, Beyond Pesticides continues its coverage of the scourge of PFAS chemicals, particularly as it relates to pesticide use and the use of fertilizers made from PFAS-contaminated “biosludge” from municipal treatment facilities. PFAS — “per- and poly-fluoroalkyl substances” — are any of a family of more than 9,000 synthetic chemicals, invented in, and widely deployed since, the 1950s in a multitude of industrial and consumer products. PFAS molecules are made up of a chain of linked carbon and fluorine atoms; the carbon–fluorine bond is one of the strongest chemical bonds that exists, which means that these compounds do not break down in the […]

(Beyond Pesticides, April 4, 2022) Recent actions by the U.S. Environmental Protection Agency (EPA) highlight the urgent need to prevent pesticides from further endangering crucial pollinators, including birds, bees, and bats. Tell EPA To Ban Neonics and Protect Against Other Threats to Pollinators. Tell Congress To Insist that EPA Does Its Job. Despite EPA’s own findings of evidence of serious threats posed by neonicotinoid (neonic) pesticides to pollinators, aquatic invertebrates, and other wildlife, it issued interim decisions on these neonics in January 2020 that disregard the science on the pesticides’ impacts and it appears that the agency is prepared to finalize these registrations late in 2022. This would, barring further action, extend the use of these harmful compounds for 15 years. Now is the time to let EPA know that continued use of neonicotinoids is unacceptable. Furthermore, building on a history of unenforceable and impractical pesticide label restrictions resulting in EPA findings of ludicrously small or no risk, the agency spun its approval of the continued use of the deadly organophosphate insecticide malathion as “protecting threatened and endangered species.” As the nation and world sit on the brink of biodiversity collapse and deadly pesticide-induced diseases, EPA actions continue to protect pesticide […]

(Beyond Pesticides. January 7, 2022) Unbeknownst to most Americans when they woke up on New Year’s Day 2022, a new labeling system for genetically modified-engineered foods— promulgated in 2019 — which does not mention genetically engineered or GMO ingredients, went into effect. Consumer, food, and environmental advocates say that the new label is misleading, insufficiently transparent, discriminatory, rife with loopholes, and confusing for consumers. The new labeling requirement mandates that genetically engineered foods bear labels that indicate that they have been “bioengineered” or that provide a text-messaging phone number or a QR code as avenues for further information. (“Additional options such as a phone number or web address are available to small food manufacturers or for small and very small packages.”) The new labeling rule from the U.S. Department of Agriculture (USDA) aims, according to the agency, to eliminate the crazy quilt of labels affixed to foods and ingredients that have been scientifically altered. According to an agency spokesperson, the rule is designed to “balance the need to provide information to consumers with the interest in minimizing costs to companies.” Genetically altered food items and ingredients have heretofore been called, and labeled as, “genetically engineered” (GE) or “genetically modified” (GM), […]

(Beyond Pesticides, June 18, 2021) As the U.S. Environmental Protection Agency (EPA) continues to drag its feet on protective regulation of neonicotinoid pesticides, states continue to step up to restrict their use. In April, the Maine legislature passed, and Governor Janet Mills has now signed, a new law that will prohibit use of neonicotinoid pesticides with the “active ingredient[s] dinotefuran, clothianidin, imidacloprid or thiamethoxam used for application in outdoor residential landscapes such as on lawn, turf or ornamental vegetation” [links by Beyond Pesticides]. Though short of an outright ban, this law is a solid step forward for Maine in reining in use of these compounds, which are neurotoxicants widely implicated in pollinator (and other insect, bird, and mammal) harms or declines. Until a federal ban happens, Beyond Pesticides offers guidance on avoiding use of neonicotinoid pesticides through its fact sheet, Managing Pests Safely Without Neonicotinoids, and its Bee Protective web pages. This new Maine law does, however, include exemptions for wood preservation, indoor pest control, use on pets, treatment of structure foundations, and controlling invasive insect pests, such as the Asian long-horned beetle, emerald ash borer, and hemlock wooly adelgid. The statute leaves other large loopholes that will permit continued use […]

(Beyond Pesticides, March 29, 2021) New data on the hazards of neonicotinoid insecticides calls for urgent regulatory action. The same pesticides that are linked to the worldwide decline of insect pollinators also present significant risks to their avian counterparts, hummingbirds. Widely known for their nectar-fueled hovering flight powered by wings beating up to 80 times per second, hummingbirds display unique reactions to toxic pesticides. Research by scientists at the University of Toronto finds that hummingbirds exposed to systemic neonicotinoid insecticides for even a short period of time can disrupt the high-powered metabolism of this important and charismatic animal. Tell EPA and Congress to save the hummingbirds by suspending use of neonicotinoid insecticides and supporting the transition to organic practices. While hovering, a hummingbird consumes calories faster than any other bird or mammal. That’s why the finding that exposure to the neonicotinoid insecticide imidacloprid slows metabolism up to 25% is so disturbing. Systemic pesticides like imidacloprid and other neonics are transported throughout the plant, including nectar. Findings on the danger neonicotinoids pose to hummingbirds decades after the chemicals were first permitted to be used in the environment, and by independent scientists, not regulatory agencies, is indicative of a regulatory approach that fails […]

(Beyond Pesticides, February 23, 2021) The same pesticides implicated in the worldwide decline of insect pollinators also present significant risks to their avian counterparts, hummingbirds. Well known for their nectar-fueled hovering flight powered by wings beating over 50 times per second, hummingbirds display unique reactions to toxic pesticides. Research by scientists at the University of Toronto finds that hummingbirds exposed to systemic neonicotinoid insecticides for even a short period of time can disrupt the high-powered metabolism of this important and charismatic animal. Scientists began their experiment by trapping 23 wild ruby-throated hummingbirds and housing them in an animal care facility. One group of birds acted as a control and received no pesticide exposure, while the rest were assigned either low, middle, or high exposure (1 part per million [ppm], 2ppm, and 2.5ppm, respectively) to the neonicotinoid imidacloprid. Scientists determined these amounts based upon probable nectar contamination in the real world. The pesticide was incorporated into the sugar solution provided to the birds over the course of three days. Within two hours of exposure to the pesticides, hummingbird metabolism dropped significantly. While the control group increased energy expenditure between 1% to 7%, the low exposed group displayed a 6% average decline, […]

(Beyond Pesticides, February 11, 2021) California sea lions (Zalophus californianus) are experiencing high rates of urogenital carcinoma (UGC) cancer incidences from the combined effect of toxic “legacy” pesticides like DDT and the viral infection Otarine herpesvirus-1 (OtHV1), according to a new study published in Frontiers in Marine Science. Previous research documents the role herpesvirus infection, genotype, and organochlorine pesticides play in sea lion cancer development. However, synergism (collaboration) between viral infection and toxic chemical exposure increases cancer development odds. Pollution of the oceans with toxic chemicals lacks adequate regulation, is widespread and only getting worse. More than 80 percent of ocean pollution comes from land-based, anthropological activities. A recent study published in Annals of Public Health finds toxic chemicals from pesticides, heavy metals, plastics, and other sources readily contaminate the ocean, especially near coastal regions where chemical inputs occur in higher concentrations. Globally, pollution has major disease implications, causing the deaths of over nine million people annually. Therefore, it is essential to understand the co-effects of ocean pollution and diseases to protect human health. Authors of the study state, “This study has implications for human health, as virally associated cancer occurs in humans, and likelihood of cancer development could similarly be increased by exposure to environmental […]

(Beyond Pesticides, February 2, 2021) The U.S. Environmental Protection Agency (EPA) will evaluate the effect of the neonicotinoid insecticide imidacloprid on endangered species, after an agreement was reached between the agency and the Natural Resources Defense Council (NRDC). Imidacloprid is one of the most commonly used insecticides in the world today and, like other neonicotinoids in its chemical class, has been linked to a range of adverse impacts on wildlife and their habitat. While the agreement to the assess effects on endangered species is important, advocates note that EPA should already have conducted this review, and further, that imidacloprid and other neonicotinoids should already be banned. NRDC’s successful lawsuit follows a separate legal challenge by the Center for Food Safety, Beyond Pesticides, beekeepers, and other environmental organizations which was settled in 2019. The judge in that case, focused on the neonicotinoids clothianidin and thiamethoxam, did not order EPA to consult with the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) (which is required when registering a pesticide in order to mitigate risks to endangered species). Instead, she directed the parties, including the plaintiffs, defendant EPA, and intervenor Bayer CropScience (the manufacturer of neonicotinoids), to move forward […]

(Beyond Pesticides, January 11, 2021) Treatment of chemical companies as clients rather than regulated entities is not new at the Environmental Protection Agency (EPA), but corruption reached new highs during the Trump administration. With a new administration, it is time to end the rule of corporate deception at EPA. This goes beyond the use of the Congressional Review Act to reverse individual rules (adopted in the last six months) that defy scientific findings and compliance with environmental and public health standards. We can no longer rely on bad science and unscrupulous chemical manufacturers that put profits above concerns for the health of people and the environment. EPA must audit pesticide registrants for integrity to scientific process and set a moratorium on future pesticide registration until the agency can assure the public that their science is not corrupt, as it has been in the past. Tell President-elect Biden and Congress to clean up the corruption of science at EPA and set a moratorium on future pesticide registrations—until the agency can assure the public that the chemical manufacturers’ science supporting pesticide registrations is not corrupt. The Midwest Center for Investigative Reporting published a story in early December on yet another example of the […]

(Beyond Pesticides, December 18, 2020) The Midwest Center for Investigative Reporting published a story in early December on yet another example of the corporate malfeasance that exalts profit far above concerns for safety, health, and ecosystems. The Midwest Center’s investigation finds that Monsanto and BASF, makers of the extremely problematic herbicide dicamba, engaged in a variety of deceitful, unethical, and possibly fraudulent practices to enable its use. The bottom line is that the companies knew, before they released dicamba, about the massive damage it would cause — and then put it on the market. Beyond Pesticides has reported on the corporate greed that fuels the downstream public health, environmental, and economic devastation these pesticides cause, and advocated for their removal from the market. Such unscrupulous behavior is not confined to these companies; Bayer (which now owns Monsanto) and Syngenta are also implicated in similar actions related to other pesticides: glyphosate and atrazine, respectively. Over the course of the past couple of decades, large agrochemical corporations have pursued not only extreme market penetration for their toxic products, but also, vertical integration that, in the case of Bayer/Monsanto, “represents a near-monopoly on the agriculture supply chain.” Corporate ownership of the patent on genetically […]

(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 25, 2020) An investigation has revealed that companies in the United Kingdom (UK), as well as in some European Union (EU) countries, are exporting massive amounts of pesticides — banned in their own jurisdictions — to poorer countries. More than 89,000 (U.S.) tons of such pesticides were exported in 2018, largely to countries where toxic pesticide use poses the greatest risks. The UK has been the largest exporter (15,000+ tons, or 40% of the total in 2018); other significant exporters include the Netherlands, France, Spain, German, Switzerland, and Belgium. Among the countries receiving the bulk of these dangerous pesticides are Brazil, South Africa, Mexico, Indonesia, and Ukraine. Despite a flurry of attention to this problem in the U.S. in the early 2000s, little has changed, worldwide, to stop this practice of selling domestically banned pesticide products to parts of the world that continue to allow their use. This is an unethical practice that compounds the risks to workers in developing countries, who already endure heighted threats to health and local ecosystems. The investigation was conducted by Unearthed, a Greenpeace UK journalism arm, and Public Eye, a Swiss NGO (non-governmental organization) that investigates human rights abuses by Swiss companies. The collaborators […]

(Beyond Pesticides, September 17, 2020) The apparel industry becomes the latest contributor to global biodiversity loss, directly linking soil degradation, natural ecosystems destruction, and environmental pollution with apparel supply chains, according to the report, “Biodiversity: The next frontier in sustainable fashion,” by McKinsey & Company. Although there are many studies on the fashion industry’s impact on climate change, much less research discusses the impact the industry has on biodiversity. 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. With the increasing rate of biodiversity loss, advocates say it is essential for government agencies to hold the fashion industry accountable for the direct (i.e., excessive agrochemical use, water consumption) and indirect (i.e., water pollution from run-off) impacts on the environment, not only to protect the well-being of animals, but humans, as well. Researchers in the study note, “We expect biodiversity to become an even greater concern for consumers and investors in the coming years. Covid-19, instead of slowing the trend, has accelerated it—perhaps because people now understand more deeply that human and animal ecosystems are interdependent. It’s time for the apparel industry, which to date has contributed heavily […]

(Beyond Pesticides, September 15, 2020) Both wild and captive primates are being exposed to hazardous pesticides and flame retardants, according to research published this month in the journal Environmental Science and Technology. This is the first study to look at the threat anthropogenic (man-made) chemicals may present for this important order of animals. “We think a lot about habitat disturbance, logging, and hunting as threats to these species, while pollution has been overlooked,” study co-author Michael Wasserman, told Environmental Health News (EHN). Scientists conducted their research by first obtaining fecal samples from three distinct primate populations: captive baboons from an Indiana zoo, wild howler monkeys from a research station in Costa Rica, and wild chimpanzees, red-tailed monkeys, and red colobus monkeys from a Ugandan national park. Samples were then tested for a range of chemicals, including 50 pesticides, and nearly 70 flame retardants. Scientists discovered legacy pesticides (such as heptachlor, DDT, hexachlorohexane, chlordane, and related compounds) in every species tested, with the highest levels found in red colobus and red-tailed monkeys. In particular, DDT and its related compounds (DDD and DDE) were found to be widespread, with red colobus monkeys registering a median of 260 ppb DDE in its waste. […]
