(Beyond Pesticides, March 9, 2021) Last week, the Environmental Protection Agency (EPA) announced an interim decision to cancel of one of the most hazardous pesticides still used in the United States, pentachlorophenol (penta). Although long overdue, health advocates are hailing the agency’s action, taken due to significant risks to human health, the availability of alternatives, and the uncertain future of penta production. Many advocates hope that EPA’s announcement is the start of a pivot to science-based decision-making in the best interest of health and the environment, not the pockets of pesticide industry executives. Cancellation of this toxic chemical will bring  the U.S. into conformance with the Stockholm Convention, an international treaty to ban persistent organic pollutants (POPs) joined by over 150 countries that was never ratified by the U.S. “This has been a long time coming,” said Jay Feldman, executive director of Beyond Pesticides. “After decades of scientific reports, lawsuits, regulatory comments, and an international ban, we’re glad EPA finally acknowledged the intrinsic dangers posed by continuing penta’s registration. We urge the agency expedite its slow cancellation timeline so that we can finally eliminate this unnecessary pollutant.” Produced for its ability to preserve wood through pressure treatment, penta has been […]

(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, January 28, 2021) Persistent organic pollutants (POPs)—including banned pesticides—present a health risk to the endangered Qinling Panda (Ailuropoda melanoleuca qinlingensis), the rarest subspecies of giant pandas, according to a new Chinese study published in Environmental Pollution. Organochlorine compounds (OCs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are well-known persistent organic pollutants. They were banned by the Stockholm Convention treaty in 2001 and are primary pollutants of concern (UNEP, 2009) 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. The U.S. was a signatory to the treaty, but U.S. Senate never ratified it, relegating U.S. officials to observer status. Although various studies demonstrate the volatile, toxic nature of POPs, much less research evaluates the impact POPs have on biodiversity over time. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one million species of plants and animals at risk. With the increasing rate of biodiversity loss, advocates say it is essential for government agencies to research how previous and ongoing use of POPs can impact present-day species. Likewise, collaborative, […]

(Beyond Pesticides, September 8, 2020) Canada should be in accordance with international treaty to eliminate persistent pollutants.  Canada is considering the elimination of one of the worst persistent pollutants—pentachlorophenol (penta)—that dot our landscape in utility poles and railroad ties. This wood preservative—a cancer-causing chemical with dioxin, furans, and hexachlorobenzene that causes health and environmental degradation—has no place in society as we struggle with shared global challenges of public and worker health threats, the climate crisis, and biodiversity decline. We have a chance to urge Canada to move ahead with a pentachlorophenol ban, joining with Mexico to show leadership in the protection of health and the environment—something the U.S. has not done. Tell Canada to ban pentachlorophenol. Canada’s Pest Management Regulatory Agency (PMRA) is accepting comments on a proposal to ban the all uses of penta in Canada. Comments are due September 13. Canada is a signatory to the Stockholm Convention on Persistent Organic Pollutants, which voted 90-2 to ban penta in 2015. The United States is not a signatory to the Stockholm Convention and still allows the use of penta on utility poles and other “wood that is subject to decay or insect infestation, including supporting structures in contact with […]

(Beyond Pesticides, August 20, 2020) Persistent organic pollutants (POPs), including banned and current-use pesticides are present in snow and ice on top of Arctic glaciers, according to the study, “Atmospheric Deposition of Organochlorine Pesticides and Industrial Compounds to Seasonal Surface Snow at Four Glacier Sites on Svalbard, 2013–2014,” published in Environmental Science & Technology. Past research finds that air contaminated with these environmentally bioaccumulative, toxic chemicals drift toward the poles, becoming entrapped in ice under the accumulating snowfall. As the global climate continues to rise and the climate crisis worsens, studies like this become significant, as glaciers encapsulating these toxic chemicals are melting. Upon melting, some chemicals can volatize back into the atmosphere releasing toxicants into air and aquatic systems, with the ensuing consequences. Although this research demonstrates that specific computer programs can track the trajectory of chemically contaminated air parcels with practical precision, it falls to global leaders to curtail the continued manufacturing of these chemical pollutants. [For related pieces, see Silent Snow: The unimaginable impact of toxic chemical use and DDT in Glacial Melt Puts Alaskan Communities at Risk.] Countless scientists consider Arctic environments to be “pristine,” void of direct chemical inputs from pesticides and other POPs. However, the Arctic has become a sink for […]

(Beyond Pesticides, June 30, 2020) A review of scientific literature on the toxic effect of environmental contaminants—including pesticides—published in the journal Toxicological Science, “The Impact of Environmental Chemicals on the Gut Microbiome,” associates these chemicals to changes in the gut microbiome and other adverse health implications. The review, by researchers at the University of Illinois, looks at how environmental contaminants adversely effects and reinforce chemical disruption of the gut microbiome. It highlights the importance of evaluating how environmental contaminants, like pesticides, impact body regulation by gut microbiota. The study has significant implications for considerations that should be, but are not currently, a part of pesticide review and registration by the U.S. Environmental Protection Agency (EPA). Gut microbiota plays a crucial role in lifelong digestion, immune, and central nervous system regulation, as wells as other bodily functions. Through the gut biome, pesticide exposure can enhance or exacerbate, the adverse effects of additional environmental toxicants on the body. Since the gut microbiome shapes metabolism, it can mediate some toxic effects of environmental chemicals. However, with prolonged exposure to various environmental contaminants, critical chemical-induced changes may occur in the gut microbes, influencing adverse health outcomes. Karen Chiu, Ph.D., a graduate research fellow at the […]

(Beyond Pesticides, May 13, 2020) A pilot study at New York University (NYU) provides evidence of a direct relationship between increased risk for celiac disease (adverse immune response to eating gluten) and exposure to endocrine-disrupting chemicals, including DDE – a metabolite of the infamous, bird-killing pesticide DDT. Researchers at NYU set out to elucidate the connection between the autoimmune disease and persistent organic pollutants (POPs), also known as “forever chemicals” or “legacy chemicals” due to their persistence in nature and the human body. The new research, published in Environmental Science, highlights higher odds for celiac disease among participants with elevated POPs exposure and differing results among male and female participants. Considering the complexity of these initial results, researcher Leonardo Trasande, Ph.D. says, “It’s not as if these chemicals were designed with the human body in mind; These chemicals were designed with materials in mind.” [See video overview here] Celiac disease produces an immune-mediated inflammatory response to the consumption of gluten, a protein found in wheat, rye, and barley. Risk for celiac disease has long been associated with genetic factors, but increased prevalence of the disease inspired further research. Considering previous studies on the deleterious impact of POPs on the immune […]

UPDATE: The same day Beyond Pesticides published this piece, Gulbrandsen Chemicals announced it would drop its effort to produce pentachlorophenol in Orangeburg, SC, according to The State newspaper. (Beyond Pesticides, March 10, 2020) Orangeburg, South Carolina may be the last place in the world to produce one of the most toxic pesticides known to humanity, pentachlorphenol. Despite a global ban on “penta” in 2016, in force in 186 countries, the United States has continued to import and use this hazardous wood preservative on telephone poles and railroad ties throughout the country. Now, with Mexico set to close one of the last production plants in the world, Gulbrandsen Chemicals Inc. wants to make Orangeburg, a majority black community with a population three times the U.S. poverty rate, the new epicenter for penta manufacturing. Overview and History Penta is used to pressure treat wood, with the aim of prolonging its use in utility poles and railroad ties. Beyond Pesticides has sounded the alarm on penta and other wood preservatives for over 20 years, starting with the reports Pole Pollution and Poison Poles, which outlined the science on the hazards and and alternatives to preservative-coated utility poles. Penta is a particularly concerning wood […]

(Beyond Pesticides, December 17, 2019) South Asian immigrants to the U.S. may be at increased risk of diabetes due to prior exposure to high levels of DDT, research published by the University of California Davis earlier this month indicates. The study highlights a blind spot for health care in the U.S., researchers say. “Our findings evoke a new interpretation of Rachel Carson’s famous book Silent Spring, in that the high DDT exposures of South Asian immigrants in the U.S. currently fall on deaf ears in the U.S.,” said lead author Michele La Merrill, PhD an associate professor in the UC Davis Department of Environmental Toxicology. “Although DDT remains in use in other nations and migration globalizes these exposures, people in the U.S. often mistakenly regard DDT exposure as no longer relevant to our society due to its ban in this country nearly 50 years ago.” When compared to other race and ethnic groups, South Asian immigrants (individuals from India, Pakistan, Bangladesh, Nepal, Sri Lanka, and Bhutan), are at greater risk of developing diabetes, even when adjusting for potential confounders such as age and obesity. Authors of the study hypothesized that this was a result of past exposure to high levels […]

(Beyond Pesticides, November 8, 2019) A new report out from As You Sow — 2019 Pesticides in the Pantry: Transparency and Risk in Food Supply Chains — focuses on the risks that agricultural pesticide use represents for food manufacturers, and offers recommendations and benchmarks for improvement in the areas of management and transparency. The report concludes that companies typically have some sort of sustainable sourcing program within their supply chains, but that most of those “lack clear criteria,” and virtually none of them includes pesticide use as an indicator. As an organization that works on shareholder advocacy to “harness shareholder power to create lasting change that benefits people, planet, and profit,” As You Sow is responding to investor and shareholder demand that companies reduce the presence of synthetic pesticide chemicals in their supply chains. No doubt this report has arisen indirectly from increased public, judicial, and media attention to the harms — to human and environmental health — of intensive pesticide use in conventional agriculture. Beyond Pesticides maintains that the real fix for the problem is a transition to organic and regenerative agriculture. Highlights of the problem in the U.S. identified in the report include: more than 1 billion pounds […]

(Beyond Pesticides, October 17, 2018) The unsustainable life cycle management of pesticides during the past seven decades has created huge stockpiles of these (and other toxic) chemicals across much of the globe, including Eastern Europe, Africa, the Middle East, and Latin America. The journal Environmental Science and Pollution Research has published a special series of articles and reports from the International HCH & Pesticides Association (IHPA), titled “The legacy of pesticides and POPs stockpiles — a threat to health and the environment.” Stockpiles have accumulated because some products have been banned for health or environmental reasons, leaving stocks (aka waste) that are often stored inadequately, and which deteriorate and migrate to contaminate the environment and put people at risk. Those affected are very often in poor, rural communities that may be unaware of the threat in their midst. Beyond Pesticides covered this “chemical time bomb” problem in 2004 and again nearly a decade ago. The special issue of Environmental Science and Pollution Research responds to multiple fronts on this problem of accumulation and storage of toxic compounds, identifying the two largest issues as: (1) the stockpile of some 4–7 million tons of hexachlorocyclohexane (HCH) waste from lindane production; and the 240,000 […]

(Beyond Pesticides, October 20, 2016) Researchers at the University of Western Australia (UWA) and Murdoch University recently released a study whose findings show that levels of pesticides in breast milk have dropped significantly over the past forty years, though some major concerns remain. Published in the international journal Chemosphere, the research shows a 42-fold decrease in levels of pesticides detected in breast milk, and ties the reduction to government efforts to prohibit persistent organic pollutants (POPs) in Australia, which has lead to decreased exposure over time. Led by UWA’s internationally renowned human lactation researcher Emeritus Professor Peter Hartmann, Dr. Donna Geddes and Murdoch’s Associate Professor Robert Trengove, the study is a testament to the positive impact banning pesticides can have on the health of individuals, especially vulnerable populations like infants, but also shows that there is a long way to go before our bodies are void of any bioaccumulated toxic residues. Researchers often study breast milk because it can bioconcentrate, or accumulate, persistent organic pollutants (POPs). Multiple studies on breast milk have been performed throughout the years, many of them confirming the fact that common toxic chemicals, such as glyphosate and triclosan, build up in our bodies over time. Most […]

(Beyond Pesticides, September 14, 2016) According to a recent study by the U.S. Geological Survey (USGS), high concentrations of dioxins and furans have been detected in tree swallow eggs collected near several sites around the Great Lakes. Other chemicals detected include polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), which were at background levels. The study is part of efforts to clean up a toxic chemical legacy around the Great Lakes, and the researchers believe their results are critical to regulators to assess “bird or animal deformity or reproductive problems” The study, “Concentrations and spatial patterns of organic contaminants in tree swallow (Tachycineta bicolor) eggs at United States and binational Great Lakes Areas of Concern, 2010—2015,” used tree swallows to quantify current exposure to organic contaminants across all five Great Lakes including 59 sites within 27  Areas of Concern (AOCs)  and 10 nearby  locations. The Great Lakes Areas of Concern refers to a U.S.-Canada  Great Lakes Water Quality Agreement  (Annex 1 of the 2012 Protocol) that  defines AOCs as “geographic areas designated by the Parties where significant  impairment of beneficial uses  has occurred as a result of human activities at the local level.” An AOC is a location that has […]

(Beyond Pesticides, August 24, 2016) Researchers at Drexel University report that higher levels of some organochlorine compounds during pregnancy are associated with autism spectrum disorder (ASD) and intellectual disability (ID). The organochlorine compounds under study have long been banned in the U.S., and include pesticides like DDT, underscoring how pervasive and persistent these chemicals are, and their continued impact on human health. The research is reported in the study  Polychlorinated Biphenyl and Organochlorine Pesticide Concentrations in Maternal Mid-Pregnancy Serum Sam ples: Association with Autism Spectrum Disorder and Intellectual Disability,  which examines whether prenatal exposure to polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) influences offspring risk of ASD and intellectual disability without autism (ID). According to the research, children born after being exposed to the highest levels of organochlorines during their mother’s pregnancy are roughly 80 percent more likely to be diagnosed with autism when compared to individuals with the very lowest levels of these chemicals. The team looked at a population sample of 1,144 children born in Southern California between 2000 and 2003. Data was accrued from mothers who had enrolled in California’s Expanded Alphafetoprotein Prenatal Screening Program, which is dedicated to detecting birth defects during pregnancy. Participants’ children were […]

(Beyond Pesticides, November 10, 2015) Exposure to organochlorine chemicals, such as DDE and PCBs, is linked to increased rates of sperm abnormalities that may lead to fertility problems, according to a new study published in the journal Environmental Health Perspectives. This is the latest study in a long line of research implicating endocrine (hormone)-disrupting chemicals in reproductive diseases. Researchers investigated this issue by observing the blood serum and sperm quality of 90 men, aged 22-44, participating in health studies in the Faroe Islands, an archipelago under  Denmark’s control that is  located between Iceland, the UK and Norway. Faroe islanders consume a high seafood diet that often consists of pilot whale, integral historically as a  food source for the Faroese people. However, this practice exposes the Faroese to higher than average levels of environmental contaminants. For the study, data on umbilical cord blood and blood serum at age 14 was available for 40 of the participants, allowing a researchers to measure lifetime impacts. Faroese participants were screened for sperm aneuploidy, a condition which usually involves an abnormal number of X or Y chromosomes in sperm, and is suspected as contributing to congenital abnormalities and up to 50% of early pregnancy losses. […]

(Beyond Pesticides, June 24, 2015) The International Agency for Research on Cancer (IARC) has found that there is some evidence in experimental animals that the popular herbicide, 2,4-D, is linked to cancer and now classifies it as a Group 2B, “possibly carcinogenic to humans.” IARC also classified lindane, used commonly in the U.S. as a topical lice treatment, in Group 1,“carcinogenic to humans” based on sufficient evidence in humans with the onset of non-Hodgkin lymphoma (NHL). These latest cancer findings come just months after the agency classified the world’s most widely used herbicide, glyphosate (Roundup), as “probably carcinogenic to humans,” raising public concerns on the lack of action from U.S. regulators. This month, 26 experts from 13 countries met at the World Health Organization’s (WHO) IARC in Lyon, France to assess the carcinogenicity of the insecticide lindane, the herbicide 2,4-D, and insecticide DDT. The findings are published in the Lancet. The new IARC findings come months after the agency classified glyphosate, the ingredient in the popular Roundup weed killer, as a Group 2A “probable” carcinogen, citing sufficient evidence of carcinogenicity based on laboratory studies. This decision sparked renewed calls for the U.S. Environmental Protection Agency (EPA) to take action on […]

(Beyond Pesticides, June 19, 2015) A new study directly links exposure to dichlorodiphenyltrichloroethane (DDT) in utero to the development of breast cancer later in life. Published in the Journal of Clinical Endocrinology and Metabolism, the study looked at data that were taken from a California program that  evaluated  samples from women during 1960s, when DDT use was popular. DDT is known to be an endocrine disruptor, and is linked to serious health effects. Although DDT has been banned for many years, residues still linger in certain areas of the U.S. and continue to cause environmental and health hazards. The recent study, titled DDT Exposure in Utero and Breast Cancer,  focuses on 118 mothers who were members of Kaiser Foundation Health Plan from 1959-1967 and had daughters that were diagnosed with breast cancer by their 50s. Stored blood samples from these mothers gave researchers an idea of how much DDT they were exposed to during pregnancy or soon after giving birth. They found that elevated levels of DDT in the mother’s blood led to a four-fold increase in the daughter’s risk of developing breast cancer. Among those with cancer, 83% had a form of cancer called estrogen positive breast cancer, which […]

(Beyond Pesticides, May 18, 2015) Delegates from more than 90 countries took the unprecedented step of voting last week for a global ban on  pentachlorophenol (penta) — a proven toxic pesticide and contaminant found  in wildlife and human biomonitoring studies worldwide. The historic vote came at the combined meetings of the Basel, Rotterdam, and Stockholm Conventions — which usually make decisions by consensus — after India repeatedly blocked action. The U.S. is not a signatory to the Stockholm Convention, which provides the framework to moving persistent organic pollutants out of commerce. During the meeting, India surprisingly rejected the findings of the Stockholm Convention’s own scientific expert committee in which it participated. Switzerland triggered the voting procedure — the first in the history of the convention. Ninety-four countries voted in favor of  global prohibition of pentachlorophenol; two opposed; and eight countries abstained. “We commend the global community for this important decision which will help ensure that the Indigenous Peoples of the Arctic and the traditional foods on which they depend are protected  against toxic pentachlorophenol,” said Pamela Miller of Alaska Community Action on Toxics. The delegates of the Stockholm Convention also supported international bans on two other  industrial chemicals that harm […]

(Beyond Pesticides, March 10, 2015) U.S. Senator Charles E. Schumer (D-NY) yesterday called on the U.S. Environmental Protection Agency (EPA) yesterday to immediately investigate the specific use of pentachlorophenol  (penta or PCP), a toxic wood preservative, to treat  utility poles throughout Long Island and urged  Public Service Electric and Gas (PSEG) Long Island to immediately suspend further use of this chemical until a  federal review  is complete. PSEG has been installing new, chemically-treated utility poles throughout the Towns of North Hempstead and East Hampton. In his press  release, Senator Schumer expresses  serious concern about penta’s  health risks to utility workers, adults and children and its ability to  move  into water over the long-term as the chemical leaches from the poles. The Senator also notes that a private firm has conducted a study based on a very limited sample size that does not consider long-term risks as the pole decomposes and further leaches toward groundwater. EPA, which is responsible for evaluating penta’s health and environmental risk, has noted public health concerns related to the chemical when ingested or inhaled, including  neurological, respiratory, kidney and immune system effects. On Long Island, 95,000 of PSEG’s 324,000 utility poles have been treated with penta. […]

(Beyond Pesticides, September 15, 2014) The Town of North Hempstead on Long Island, New York has passed a new law requiring warning labels on the utility poles that are treated with the hazardous wood preservative, pentachlorophenol  (PCP). At the town board meeting on September 9, a vote of 7-0 mandated the labeling with the following warning: “This pole contains a hazardous chemical. Avoid prolonged direct contact with this pole. Wash hands or other exposed areas thoroughly if contact is made.” Since the Long Island Power Authority (LIPA), operated by Public Service Enterprise Group (PSEG), installed thousands of new hurricane-resistant utility poles that are thicker and taller, it shed  more light on the community hazards  associated with use of pentachlorophenol. Of the 324,000 utility poles on Long Island, about 95,000 have been treated with PCP. Even though there is a prohibition  of PCP for residential uses within the U.S., it still can be used on utility poles, railroad ties and other industrial uses under  federal law. The U.S. Environmental Protection Agency (EPA) defines pentachlorophenol as “extremely toxic” to humans even from short-term exposure and is listed as a “probable human carcinogen.” The inhalation or ingestion can lead to cancer, Hodgkin’s disease, […]

(Beyond Pesticides, August 7, 2014) Residents of St. Louis, Michigan aren’t used to seeing large excavators and dump trucks haul piles of dirt from their front yards or entire blocks of big, neighborhood trees felled. What they are used to seeing are dead birds ””sometimes even spontaneous, mid-flight deaths of the birds”” and because of a toxic series of events, disasters, and delays spanning decades, the two sights are inextricably connected. As one St. Louis resident described to the Detroit Free Press, dozens of dead robins and blackbirds had been collected from her backyard in the 18 years she has lived there, with the most recent just a couple weeks ago. This experience and other similar stories from the area prompted researchers at Michigan State University (MSU) to start figuratively and literally digging. Matt Zwiernik, Ph.D., an environmental toxicologist at MSU, and volunteers collected 29 dead birds, including 22 robins, last year from a nine-block residential area in St. Louis. The scientific sampling was only a small portion of the dead birds they could have collected, Dr. Zwiernik explained to reporters at the Detroit Free Press, as time, distance, logistics, and access to property sometimes limited collection efforts. Nevertheless, it […]

(Beyond Pesticides, June 30, 2014) Decades later there are still horrifying impacts from a legacy of dumping in the environment tens of thousands of pounds of chemical waste used in the production of pesticides. The production  by the Hooker Chemical Company of C-56, the progenitor of many now banned organochlorine pesticides, has resulted in contamination and hardship. Beyond Pesticides has long advocated for the elimination of hazardous synthetic pesticides, due to unnecessary risks that put the health of both people and entire communities in jeopardy. Long after the Depression Era in Montague, MI, there were still many families who were left jobless and looking for any means to bring back a better life. The town decided to stimulate the local economy by recruiting Hooker Electrochemical Company; a chemical manufacturer originally based in New York, where it had been using an old canal bed for disposal of waste in the 1940s and was looking for a new site to build a chlor-alkali plant. Ninety-six percent of local residents signed the petition to bring them in. The situation was perfect for Hooker, which needed the vast underground reserves of salt and the lake water in the town for cooling during its industrial […]

(Beyond Pesticides, April 15, 2014) A new study released last week by the National Park Service on contaminant use in Alaska, found traces of pesticides in fish ””pesticides which have long been banned and likely never been used within the Alaskan wilderness areas. Researchers examined three Alaskan parks renowned for their remote, pristine and protected wilderness ””Lake Clark National Park, Wrangell-St. Elias National Park and Katmai National Park”” only to find that contaminants, including PCBs at concentrations exceeding those in the lower 48 states. The study, Contaminants of Emerging Concern in Fish from Western US and Alaska National Parks””Spatial Distribution and Health Thresholds, published in the Journal of the American Water Resources Association, sought to compare contaminant level found within fish across the nation. Generally, researchers found that Alaskan fish were more likely to have traces of older chemicals, while those in the lower 48 tended to be dominated by newer chemicals. The most commonly detected chemicals are PCBs, endosulfan, sulfate and p,p’-DDE, a breakdown product of DDT.  Some of these long-banned chemicals actually exceed the U.S. Environmental Protection Agency’s (EPA) guidelines for human subsistence on fish and wildlife. Among those exceeding acceptable levels, dieldrin, chlordane, and p,p’-DDE have been […]
