New research on birth defects at extremely low concentrations and documentation of widespread ground- and drinking-water contamination has strengthened the case for banning the toxic compound atrazine, the most commonly used herbicide in the US.
Atrazine is a widely used weed killer that chemically castrates male frogs at extremely low concentrations and is linked to significant human and wildlife health concerns, including endocrine disruption, birth defects, fertility problems, and certain cancers.
“It’s time to ban atrazine to protect our drinking water and our most imperiled wildlife,” said Jeff Miller, a conservation advocate with the Center for Biological Diversity. “There is no reason to continue use of this poisonous contaminant given the building evidence of harm to humans and endangered species.”
Atrazine is a potent chemical that is the most common contaminant of ground-, surface, and drinking water across the US. Recent research published in peer-reviewed journals suggests that small amounts of atrazine in drinking water can be harmful at much lower concentrations than federal standards, and link the pesticide to birth defects, low birth weights, premature births, and menstrual problems. Previous research has provided evidence linking atrazine to prostate cancer and decreased sperm count in men, and higher risk of breast cancer in women.
Articles this week in the New York Times, Washington Post, and Huffington Post discuss how the Environmental Protection Agency is ignoring unsafe atrazine contamination levels in surface and drinking water in the Midwest and South. Agency documents show that numerous watersheds and drinking-water systems are contaminated with atrazine, which was banned by the European Union and in Switzerland, the home country of its parent company Syngenta, because of dangers to both people and wildlife.
Atrazine is linked to declines of endangered amphibians and fish in California such as the California red-legged frog, California tiger salamander, Delta smelt, coho and chinook salmon, and steelhead trout. Atrazine also harms many other endangered species throughout the country, including sea turtles in Chesapeake Bay, Barton Springs salamanders in Texas, endangered mussels in Alabama, shortnose sturgeon in Midwest waters, the Wyoming toad, and the Illinois cave amphipod.
Numerous studies have definitively linked pesticides and herbicides with significant developmental, neurological, and reproductive damage to amphibians. Pesticide contamination can cause deformities, abnormal immune system functions, diseases, injury, and death.
Studies by Dr. Tyrone Hayes at the University of California show that atrazine is an endocrine disruptor that interferes with reproduction and “assaults male sexual development.”
Dr. Hayes demonstrated that atrazine chemically castrates and feminizes male frogs at concentrations 30 times lower than levels allowed by the EPA. Although exposure levels as low as 0.1 parts per billion (ppb) result in frog hermaphrodites, the agency’s atrazine criterion for the “protection of aquatic life” is 12 ppb.
Conservationists sued the EPA in 2003 for failing to review the impacts of atrazine on several endangered species. The registration for atrazine was revised later that year, revealing the agency’s obeisance to the agrochemical industries it was intended to regulate. Despite numerous studies and overwhelming evidence linking atrazine to significant human and wildlife health concerns, the agency imposed no new restrictions on its use.
The Center for Biological Diversity has mounted a Pesticides Reduction Campaign to hold the EPA accountable for pesticides it registers for use and to cancel or restrict use of harmful pesticides within endangered species’ habitats.
The Center's 2004 report, Silent Spring Revisited: Pesticide Use and Endangered Species, details the decades-long failure of the agency to regulate pesticides harmful to endangered species. In 2006 the Center published Poisoning Our Imperiled Wildlife: San Francisco Bay Area Endangered Species at Risk from Pesticides, a report analysing the agency’s dismal record in protecting Bay Area endangered species and the agency’s ongoing refusal to reform pesticide registration and use in accordance with scientific findings.
