EPA Takes Emergency Action To Stop Use of Dangerous Pesticide

An anonymous reader quotes a report from the Washington Post: For the first time in 40 years, the Environmental Protection Agency has taken emergency action to stop the use of a pesticide (source may be paywalled; alternative source) linked to serious health risks for unborn babies. Tuesday's emergency order applies to dimethyl tetrachloroterephthalate, also known as DCPA, a weedkiller used on crops such as broccoli, Brussels sprouts, cabbage and onions. When pregnant farmworkers and others are exposed to the pesticide, their babies can experience changes to fetal thyroid hormone levels, which are linked to low birth weight, impaired brain development, decreased IQ and impaired motor skills later in life. "DCPA is so dangerous that it needs to be removed from the market immediately," Michal Freedhoff, assistant administrator for the EPA's Office of Chemical Safety and Pollution Prevention, said in a statement. "It's EPA's job to protect people from exposure to dangerous chemicals. In this case, pregnant women who may never even know they were exposed could give birth to babies that experience irreversible lifelong health problems." The European Union banned DCPA in 2009. But the EPA has been slower to act, frustrating some environmental and public health advocates. In an interview, Freedhoff said that EPA scientists have tried for years to get more information on health risks from the sole manufacturer of the pesticide, AMVAC Chemical. But she said the company refused to turn over the data, including a study on the effects of DCPA on thyroid development and function, until November 2023. "We did make some good-faith efforts to work with the company," Freedhoff said. "But in the end, we didn't think any of the measures proposed by the company would be implementable, enforceable or effective." "DCPA has been used in the United States since the late 1950s," notes the report. "After the pesticide is applied, it can linger in the soil, contaminating crops later grown in those fields, including broccoli, cilantro, green onions, kale and mustard greens." "The emergency order Tuesday temporarily suspends all registrations of the pesticide under the Federal Insecticide, Fungicide and Rodenticide Act. The agency plans to permanently suspend these registrations within the next 90 days."
