72 Toxic Inert Ingredients No Longer Used in Pesticide Products Cancelled, 300 Others Still Not Listed on Labels

(Beyond Pesticides, December 23, 2016) The Environmental Agency (EPA) has finalized a proposal to ban 72 inert (or secret hazardous) ingredients from use in pesticide formulations following a long fight with environmentalists who, in 2006, asked that pesticide product labels disclose any of 371 inert ingredients that could be in products. While this finalization is a step in the right direction, ultimately the move is viewed by advocates as inadequate. The original petition, submitted by Northwest Coalition for Alternatives to Pesticides, along with Beyond Pesticides, Physicians for Social Responsibility, and nearly 20 other organizations, called on the agency to require disclosure of inerts. To put the announcement in perspective, EPA is acting on 72 inert ingredients that are no longer being used, such as turpentine oil, and nitrous oxide. An inert ingredient is defined as any ingredient that is “not active,” or specifically targeted to kill a pest. According to a 2000 report produced by the New York State Attorney General, The Secret Ingredients in Pesticides: Reducing the Risk, 72 percent of pesticide products available to consumers contain over 95 percent inert ingredients and fewer than 10 percent of pesticide products list any inert ingredients on their labels. The report also found […]

Nitrate Pollution in Groundwater Linked to Birth Defects, Cancers and Thyroid Problems

(Beyond Pesticides, October 6, 2016) According to a report published last week by the Iowa Environmental Council (IEC), the associations between elevated levels of nitrate in drinking water and health risks go well beyond the “blue-baby syndrome” and nitrate concentrations lower than the drinking water standard may be harmful through long-term exposure. The lead author of the report, Ann Robinson, Agricultural Policy Specialist at IEC, stated that the focus was on “significant findings that multiple studies have associated with nitrate in drinking water, including birth defects, bladder cancer and thyroid cancer.”  Nitrate is a common groundwater contaminant that is sourced mainly from chemical fertilizers and animal waste. Nitrate is a common contaminant of drinking water, particularly in agricultural areas where nitrogen fertilizers are used. In 1962, the U.S. Environmental Protection Agency (EPA) established the drinking water standard of 10 mg/L of nitrate to prevent blue baby syndrome, a fatal infant blood disease. In addition to Iowa, the U.S. Geological Survey has also identified the following states as areas with high risk clusters from nitrate contamination to groundwater: Oklahoma, Kansas, Nebraska, North and South Dakota, Illinois, Minnesota, Pennsylvania, and Maryland. The report reviewed studies conducted in the U.S., Canada, and Australia […]

Take Action to Ban Atrazine: EPA Must Protect Wildlife!

(Beyond Pesticides, September 16, 2016) Tell EPA to ban all uses of atrazine in the United States! Atrazine, widely used on food and feed crops, golf courses, and residential lawns, is a potent endocrine disruptor that is  strongly associated with birth defects, cancer, sex reversal and hermaphroditism in many different animals. The European Union and other countries have banned atrazine, however EPA continues to put U.S. citizens and the environment in harm’s way, allowing nonstop use of this toxic chemical. Sign Beyond Pesticides’ petition to ban atrazine by October 5, 2016. Atrazine is the second-most widely used pesticide in the U.S., with over 73 million pounds applied each year. Atrazine has washed into surface water and leached into groundwater, spurring community water utilities  across the U.S. to file class-action lawsuits to remove the pesticide from drinking water supplies. Even at levels established as “safe” or acceptable by EPA drinking water standards, atrazine is linked to endocrine-disrupting effects. EPA is not adequately assessing the effects of atrazine by using high dose testing models, which are not appropriate for hormonally-active substances  that  often show effects at minute doses. Studies by Tyrone Hayes, Ph.D., University of California, Berkeley,  and others have shown that […]

Legacy Contaminants Found in Swallow Eggs around the Great Lakes

(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 […]

Miami-Dade Stops Aerial Spraying on Weekdays to Reduce Exposure to Students

(Beyond Pesticides, August 25, 2016) The County of Miami-Dade announced Tuesday that it will no longer conduct aerial sprayings on weekdays, to avoid exposing children and teachers. In an effort to control the spread of Zika, the county is consulting with the Centers for Disease Control and Prevention (CDC) and the Florida Department of Health (FDOH), to spray a neighborhood in the county, Wynwood, with Bacillus thuringiensis israelensis (Bti) and Naled. Mosquito officials were conducting the spraying during the early hours of the morning, when fewer people were around, the first day of the school year in Miami-Dade started this week, putting teachers and students at risk of exposure at bus stops. The county’s move is encouraging, because as research has continuously shown, children and pesticides don’t mix.  Studies show children’s developing organs create “early windows of great vulnerability” during which exposure to pesticides can cause great damage. Childhood pesticide exposure has been linked to a range of adverse health endpoints, including cancer, asthma, impaired sexual development, ADHD and other learning disabilities. “We have adjusted our spraying schedule to avoid any inconvenience to our local school system, and the children, families, and teachers in our community,” the office of Mayor […]

Banned Chemicals Linked to Increased Autism Risk

(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 […]

Australian Study Finds Nearly Half of Insecticide Poisonings Affect Young Children

(Beyond Pesticides, August 16, 2016) Young children are disproportionately poisoned by toxic pesticides used indoors, according to a study published in the Australian and New Zealand Journal of Public Health. Data analyzed from the Queensland, Australia Poisons Information Centre (QPIC) finds that 49% of 743 insecticide-related calls in 2014 concerned young children. Given that children are more sensitive to pesticide exposure than adults because they take in more of a chemical relative to their body size and have developing organ systems, this data underscores the importance of educating the general public about alternatives to the use of toxic pesticides in and around the home. A significant share of childhood pesticide poisonings occurred in very young children. “Children in the one-year age group were at greatest risk — as they’re at that stage where they spend a lot of the time on the floor and put things in their mouth,” said Karin English, PhD candidate at the University of Queensland. As a result of children’s propensity for hand to mouth motion, cockroach baits and ant liquid were found to be the most common source of insecticide exposure for kids under five, covering 39% of calls. However, Ms. English notes that enclosing […]

Study Adds to Findings that Link Prenatal Pesticide Exposure to Lower IQs

(Beyond Pesticides, July 29, 2016)  A study released earlier this week finds lower IQ (intelligence quotient) in children born to mothers who during their pregnancy were living in close proximity to chemical-intensive agricultural lands where organophosphate pesticides were used. This study adds to the body of scientific literature that links prenatal exposure to organophosphate pesticides with lower IQ’s in children. Organophosphate pesticides, a relatively older generation of highly neurotoxic pesticides still widely used on farms in California, have been associated with a  broad range of diseases  in both children and adults.  This  latest study  supports health and environmental advocates’ call to eliminate these toxic pesticides in agriculture and move toward safer, sustainable, and organic management practices. The study, titled  Prenatal Residential Proximity to Agricultural Pesticide Use and IQ in 7-Year-Old Children, looks at 283 women and children from the agricultural Salinas Valley who are enrolled in the long-term Center for the Health of Mothers and Children in Salinas (CHAMACOS) study. Specifically, researchers looked at pregnant women living within one kilometer of agricultural fields where organophosphate pesticides were used. They found that at age 7, the children of those women had declines of approximately two IQ points and three verbal reasoning […]

Colombia Cautiously Declares End to Mosquito-Borne Zika Epidemic

(Beyond Pesticides, July 27, 2016) In South America, Colombia has officially declared an end to its Zika epidemic. The country, which previously had the highest cases of suspected Zika virus infection after Brazil, with a total of more than 99,721 people infected since September 2015 have registered a drop in the number of infections to 600 new cases a week, down significantly from a peak of more than 6,000 cases a week in February, according to health officials. Fernando Ruíz, M.D., Deputy Minister of Health and Service Provision in Colombia, said the numbers signaled that the epidemic had given way to an endemic phase of the disease, in which it continues to be present but spreads much more slowly. This news arrives following the publication of Zika Virus Disease in Colombia —Preliminary Report, which suggests that infe ctions late in pregnancy may pose less risk to the fetus than widely feared. The report follows thousands of women in Colombia who have had symptoms consistent with Zika virus disease during pregnancy to try to better understand the risk the virus poses. At the time of the report, the country had only seven official cases of microcephaly, a birth defect marked by […]

Health Canada Moves to Limit Exposure to Boric Acid Pesticides

(Beyond Pesticides, July 26, 2016)  Health Canada’s Pest Management Regulatory Agency (PMRA) announced this week it will cancel certain  formulations  of boric acid-based pesticides. The announcement reflects the latest science showing that certain products, such as those in dust formulations or open baits, put residents at inhalation and ingestion exposure risk, respectively, to the naturally occurring element  boron and borate compounds. PRMA’s decision  is part of the Health Canada’s registration review of boric acid, which, like that of the U.S. Environmental Protection Agency (EPA), is conducted every 15 years. PRMA is cancelling the following uses of boric acid and similar compounds All domestic dust formulation products All domestic granular formulation products Domestic solution formulation products, with the exception of enclosed bait stations and spot treatment with gel formulations For other uses, PRMA has amended label requirements to better protect handlers and users of the pesticide. For example, the agency will update label directions to specify that boron products can only be applied to areas inaccessible to children and pets. Jane Philpott, Minister of Health in Canada said in a press release, “even natural ingredients like boric acid can pose a risk to Canadians. That’s why Health Canada looks at all […]

California to List Atrazine and Other Triazine Weedkillers to Prop 65 as Reproductive Toxicants

(Beyond Pesticides, July 13, 2016) California’s Office of Environmental Health Hazard Assessment (OEHHA) has announced that atrazine, its chemical cousins,  propazine,  simazine,  and its break down triazine compounds des-ethyl atrazine (DEA),  des-isopropyl atrazine (DIA)  and  2,4-diamino-6-chloro-s-triazine (DACT)  would be added to the list of chemicals known to the state to cause reproductive toxicity for purposes of the state’s Proposition 65. The formal listing has been delayed and will not be effective until July 15, 2016 due to litigation from the manufacturer, Syngenta, which opposes the listing. In 2014 the state announced its Notice of Intent to list the triazines: atrazine, propazine, simazine and their breakdown products under Proposition 65 — the state’s law on toxic chemicals. The listing of these chemicals was initially to be effective on August 3, 2015. However, Syngenta, manufacturer of atrazine, challenged the listing decision, leading to a delay in the formal decision. Syngenta Crop Protection v OEHHA  (Sacramento Superior Court case#34-2014-800001868). Syngenta’s challenge was unsuccessful and now the official listing can move forward, in spite of Syngenta’s pending appeal. The six chemicals will now be known as reproductive toxicants in the state of California effective July 15, 2016.

Exposure to Pesticides Linked to ALS Risk

(Beyond Pesticides, May 16, 2016) Pesticide exposure may increase the risk of amyotrophic lateral sclerosis (ALS), according to a study entitled Association of Environmental Toxins With Amyotrophic Lateral Sclerosis, which was  published in JAMA Neurology. ALS, also known as Lou Gehrig’s disease, is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. The study, which investigated a total of 122 persistent environmental pollutants, including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and brominated flame retardants (BFRs), found that pesticide exposure increased ALS risk five-fold. Researchers conducting the study  looked at 156 patients with ALS and 128 without the disease. Participants were asked about occupational and residential exposure to environmental toxicants  and blood samples were taken to measure their concentrations. Researchers found that the organochlorine pesticides pentachlorobenzene and cis-chlordane increased ALS risk two-fold and nearly six-fold, respectively. This study does not prove that pesticides cause ALS, but it does build on an association suggested in previous research, study co-author Stephen Goutman, MD, told  HealthDay. Dr. Goutman recommends avoiding pesticides. This is especially wise for anyone with a family history of ALS, he added. The link between pesticide exposure and neurological damage has been studied extensively. In 2008, […]

Fungicides Linked to Autism and Alzheimer’s Disease

(Beyond Pesticides, April 1, 2016) A study published yesterday finds  that a certain class of fungicides, the strobilurins, causes genetic changes in the neurons of mice that are similar to genetic changes seen in humans with autism and Alzheimer’s disease. Since their introduction to the market over the past 20  years, these fungicides have been used increasingly on conventionally grown crops like cabbage, spinach, lettuce, kale, tomatoes, apples, pears and grapes. After exposing brain cells from mice to over 300 pesticides and fungicides, researchers found that the strobilurin class of fungicides produces patterns of genetic changes often seen in human neurodegenerative diseases. While the fungicides created autism-like signatures in the way the genes were expressed in mouse neurons, the results do not conclusively show that this class of fungicides causes autism or Alzheimer’s disease. Mark Zylka, Ph.D., lead scientist of the study and associate professor of cell biology and physiology at University of North Carolina, states,  “What this work provides is evidence that these chemicals are bad for neurons. They turn the same genes on or off that you see not only in autism brains, but also in neurodegeneration.” Strobilurins work by disrupting mitochondria, commonly known as the “powerhouse of […]

Congressional Reps Want EPA Review of Glyphosate-2,4-D Mixture Enlist Duo

(Beyond Pesticides, February 18, 2016) Last week, 35 members of Congress, led by Representatives Earl Blumenauer (OR-3) and Peter DeFazio (OR-4), signed a letter to Environmental Protection Agency (EPA) Administrator Gina McCarthy, challenging  EPA’s review process for the  glyphosate  and  2,4-D  herbicide mixture, known as Enlist Duo. It is produced by Dow AgroSciences for use in genetically engineered  crops. The letter requests “more information about EPA’s plan to reevaluate Enlist Duo’s health and environmental risks.” The letter comes just weeks after the 9th U.S. Circuit Court of Appeals denied a request from EPA to vacate its own decision to  approve the  toxic herbicide cocktail. Because of the court’s decision, EPA is solely responsible for the decision about Enlist Duo’s registration. “This is part of a vicious cycle that is leading to more potent, dangerous chemicals being widely used on crops across the United States,” said  Rep. Blumenauer. He continued, “With the rise of herbicide-resistant genetically modified crops, herbicides are more widely sprayed causing weeds to grow more resistant — ultimately, requiring the application of even stronger herbicides. EPA must take action to make sure products entering the market to be used on our food are safe for human health and […]

Pesticide Exposure Linked to Abnormal Sperm Development

(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.

Lawsuit Challenges EPA on Toxic Herbicide Cocktail for GE Crops

(Beyond Pesticides, October 27, 2015) Late Friday,  a coalition of public health, conservation and food safety groups filed their opening brief in the ongoing legal challenge to the U.S. Environmental Protection Agency’s (EPA) approval of the herbicide Enlist Duo for use on genetically engineered corn and soybeans. Enlist Duo, a blend of glyphosate and 2,4-D, was approved on October 15 for use on genetically engineered (GE) crops, despite concerns for human and environmental contamination. The challenge was originally brought in November 2014, shortly after the EPA approved the controversial herbicide for 6 Midwest states. Since then, EPA has expanded its approval to a total of 15 states, with more expected. Counsel from the Center for Food Safety (CFS) and Earthjustice are jointly representing Beyond Pesticides, Center for Biological Diversity, CFS, the Environmental Working Group, the National Family Farm Coalition, and Pesticide Action Network North America. “The Enlist Duo approval violated the laws protecting our communities, land, and farms,” said George Kimbrell, Center for Food Safety senior attorney, counsel in the case. “Regulators bowed to the chemical industry, but we are committed to holding them accountable.” The groups argue that in its approval of Enlist Duo, a combination of the herbicides […]

Reproductive Health Experts Call for Action on Toxic Chemicals

(Beyond Pesticides, October 6, 2015) Last week, the International Federation of Gynecology and Obstetrics (FIGO) released a statement encouraging broad-based policy measures that prevent exposure to toxic environmental chemicals. “The global health and economic burden related to toxic environmental chemicals is in excess of millions of deaths and billions of dollars every year,” the report unequivocally states. FIGO’s statement follows a similar call to action from the American College of Obstetricians and Gynecologists in 2013 and the American Academy of Pediatrics in 2012. The piece lays out broad themes surrounding exposure to toxic chemicals, including issues of environmental justice, prenatal exposure and subsequent health effects, and overall global health and economic burden. Based on these impacts, several recommendations are submitted for obstetricians, gynecologists, midwives, women’s health nurse practitioners, nurses, and other health professionals to follow to achieve a goal of “prevention for all.” FIGO highlights how people of low-income, particularly in poverty-stricken countries, bare a higher burden of toxic exposure than richer nations. “[A]t every stage of development, the consequences of exposure to toxic chemicals —including morbidity and mortality, loss of family income and productivity, and environmental degradation— are disproportionately borne by people with low incomes,” the piece states. FIGO […]

Yale Study Links Prenatal Pesticide Exposure to Tremors in Children

(Beyond Pesticides, October 05, 2015) According to a Yale University study, prenatal exposure to the widely used agricultural pesticide chlorpyrifos is linked to tremors — involuntary contraction or twitching of muscles — in childhood. Chlorpyrifos, a broad-spectrum chlorinated organophosphate insecticide also known as Dursban, may also affect the cardiovascular and respiratory systems and is acutely toxic to bees, birds, mammals, and aquatic life. The study, titled Prenatal exposure to the organophosphate pesticide chlorpyrifos and childhood tremor  and published in the journal Neurotoxicology, measured the presence of chlorpyrifos in umbilical cord blood samples in 263 low-income, inner-city minority children. In 2001, the U.S. Environmental Protection Agency (EPA) banned residential use of chlorpyrifos, which was prominent in urban areas at the time. However, the study participants  —263 minority mothers  and their children, all from low income  communities in New York  City— were assembled in 1997,  before the ban was imposed. In  1997, the initial measure of each  child’s prenatal exposure to CPF  was taken from umbilical cord  blood. The children were then followed until approximately 11 years of age, after which they underwent a neurophysical assessment, which included a short drawing test. Researchers found that compared to all other children, those who […]

Mosquito Fogging Kills Hundreds of Bees

(Beyond Pesticides, August 19, 2015) Local fogging for  mosquito control turned tragic for a Palo Alto, California beekeeper who lost hundreds of honey bees from his backyard hives. The beekeeper, who also produces organic honey, now fears his honey is contaminated. The fogging, which occurred last month, was in response to positive tests for West Nile virus in mosquito samples. Many mosquito control pesticides are toxic to honey bees and given the declining populations of pollinators, vector control officials are being asked to carefully consider the risks associated with pesticide spraying. According to the local NBC affiliate, beekeeper Rondolph Tsien believes he was not given sufficient time to protect his bees from the mosquito fogging and, despite trying to cover his hives with a tarp to protect his bees from drifting pesticides, many were lost. A mosquito sample tested positive for West Nile virus about one mile from Mr. Tsien’s home, putting his property in the catchment area for fogging. Mr. Tsien worries the surviving bees will produce contaminated honey that can no longer be labeled organic. A Santa Clara County Vector Control representative stated during an interview that the county uses  an “extremely low dose” of pesticides during fogging […]

Bee and Bird-Toxic Pesticides Found in Food Served at Congressional Dining Hall

(Beyond Pesticides, August 4, 2015) Nearly every food available for purchase at the U.S. Congressional Dining Hall contains detectable levels of neonicotinoids (neonics), chemical insecticides implicated in the global decline of wild and managed pollinators. The results of a new study, performed by the American Bird Conservancy (ABC) and the Harvard T.H. Chan School of Public Health, reveals how reliance on these toxic chemicals can both directly and indirectly affect  our food supply. Authors of the study hope the results will build Congressional support for the Saving America’s Pollinators Act of 2015, which would suspend the use of neonics while an independent review analyzes the chemical’s effects to birds, pollinators, and other wildlife. Researchers for the study conducted two rounds of food testing, the first in January, and the second in May 2015. Approximately half of samples were taken from the House Longworth Cafeteria and half from Senate Dirksen Cafeteria in Washington, D.C. In total, 66 food samples were tested for the presence of neonicotinoids. Of that, 60, or 91% of samples tested positive for one neonic, and 47, or 71% of samples had two or more neonics present. “We were surprised to find that most foods contained multiple neonicotinoids, […]

Carcinogenic Glyphosate Linked to DNA Damage, as Residues Are Found in Bread

(Beyond Pesticides, July 22, 2015) Months after the World Health Organization (WHO) formally associated the world’s most widely used herbicide  -glyphosate (Roundup)- with cancer, one of the world’s leading experts on cancer risk, and co-author of the WHO’s report, Christopher Portier, PhD, told a scientific briefing in London that the herbicide can damage human DNA, which could result in increased cancer risks. This finding comes on the heels of a call by the Soil Association for a United Kingdom (UK) ban on the use of glyphosate after finding residues of the chemical in bread. Earlier this spring, the WHO’s International Agency for Research on Cancer (IARC) classified glyphosate as Group 2a “probable” human carcinogen based on sufficient evidence of carcinogenicity in laboratory animals. Since then industry has hit back defending its champion product, even attempting to undercut the WHO’s findings with an industry-based  assessment that reached the opposite conclusion, based on classified industry reports.  Now an internationally recognized scientist, Dr.  Portier, former associate director, National Institute of Environmental Health Sciences, (NIEHS) and director of the Office of Risk Assessment Research at NIEHS, reiterated WHO’s findings at the UK Soil Association scientific briefing in Westminster on July 15.

EPA at Odds with Scientists on Endocrine System Effects of Weedkillers Atrazine and 2,4-D

(Beyond Pesticides, July 6, 2015) With the release of its  Tier 1 screening results  for the first 52 pesticide chemicals (active and inert ingredients) evaluated under  the Endocrine Disruptor Screening Program (EDSP), the U.S. Environmental Protection Agency (EPA) is at odds with a large body of scientific evidence worldwide that identifies many of these chemicals, most notably the herbicides  2,4-D  and  atrazine,  as interacting with the endocrine system or acting as endocrine disruptors. Independent scientific data has shown these chemicals to interfere with the hormone system. EPA’s EDSP is a multi-step process used to ensure that exposure to chemicals does not result in adverse human health and environmental effects that canoccur from the disruption of hormones. The two-tiered screening and testing system requires that EPA identify which chemicals are able to interact with the endocrine system, specifically with three hormonal pathways — estrogen, androgen, and thyroid — in Tier 1. Tier 2 is designed to go one step further, requiring EPA to determine endocrine effects across taxa (e.g. mammals, birds, amphibians, and invertebrates) as well as potential effects on non-endocrine systems (e.g. neurological, immunological, hepatic, and renal).  According to EPA, Tier 1 screening data are the best way to determine […]

Atrazine and Glyphosate To Be Analyzed by EPA for Impacts on 1,500 Endangered Species

(Beyond Pesticides, June 25, 2015) The U.S Environmental Protection Agency (EPA) announced Tuesday that it will analyze the effects of two of the most commonly used pesticides in the United States, glyphosate and atrazine, along with atrazine chemical-cousins propazine and simazine, for their impacts on 1,500 endangered plants and animals. The announcement marks an agreement between EPA and Center for Biological Diversity (CBD) on a proposed settlement amending a 2010 court order that  established a schedule to complete effects determinations for 75 chemicals on 11 species in the San Francisco (SF) Bay Area. According to EPA, 59 of the 75 pesticides have been evaluated and subject to  effects determinations, however for the remaining 16 pesticides, EPA and CBD agreed that it would be more efficient and environmentally significant to complete nationwide effects determinations, rather than limit their focus to the SF bay area listed species. The agency has committed to completing the assessments by June 2020. The initial lawsuit was filed by CBD in May 2007 against EPA for violating the Endangered Species Act by registering and allowing the use of scores of toxic pesticides in habitats for 11 San Francisco Bay Area endangered species without determining whether the chemicals […]
