Environmental Protection Agency (EPA) head Scott Pruitt denied a 10-year-old petition late Wednesday to ban the use of chlorpyrifos, a widely-used pesticide that harms children\u0026#039;s brains, in a decision that outraged public health advocates and environmentalists.In greenlighting the dangerous chemical, the EPA defied its own research—and acquiesced to Dow Chemical, the maker of chlorpyrifos, which has been lobbying the agency for years to allow the pesticide\u0026#039;s continued use.EPA Chief Pruitt\u0026#039;s move rejecting his scientists\u0026#039; advice to ban a pesticide?That\u0026#039;s exactly what the pesticide maker, DowChem, asked for. https://t.co/TJo5wUpCCY— ProPublica (@ProPublica) March 30, 2017\u0022Without the ban, farmworkers, their children, and others can\u0026#039;t escape exposure because the poison is in [the] air they breathe, in the food they eat, the soil where children play.\u0022—Erik Nicholson, United Farm WorkersAs the Natural Resources Defense Council (NRDC) observed: \u0022The Trump EPA\u0026#039;s denial of the NRDC and Pesticide Action Network 2007 petition to ban chlorpyrifos contradicts EPA\u0026#039;s own analysis from November 2016 (just five months ago!) that found widespread risk to children from residues of the pesticide on food, in drinking water, and in the air in agricultural communities. Up until last night, EPA explained that because of these risks a ban was needed to protect children\u0026#039;s health.\u0022Environmental law group Earthjustice listed the risks the EPA discovered through its own research into chlorpyrifos:All exposure to chlorpyrifos through food exceeds safe levels of the chemical. The most exposed population is children between one and two years of age. On average, this vulnerable group is exposed to 140 times the level of chlorpyrifos the EPA deems safe.Chlorpyrifos contaminates drinking water.Chlorpyrifos drifts to schools, homes, and fields in toxic amounts at more than 300 feet from the fields.Workers face unacceptable risks from exposures when they mix and apply chlorpyrifos and when they enter fields to tend to crops.There is little doubt about the science. Mother Jones\u0026#039; Tom Philpott reported that \u0022Stephanie Engel, an epidemiologist at the University of North Carolina and a co-author of [a major study on chlorpyrifos at Mount Sinai], says the evidence that chlorpyrifos exposure causes harm is \u0026#039;compelling\u0026#039;—and is \u0026#039;much stronger\u0026#039; even than the case against BPA (bisphenol A), the controversial plastic additive. She says babies and fetuses are particularly susceptible to damage from chlorpyrifos because they metabolize toxic chemicals more slowly than adults do. And \u0026#039;many adults\u0026#039; are susceptible, too, because they lack a gene that allows for metabolizing the chemical efficiently, Engel adds.\u0022And the New York Times reported that \u0022Jim Jones, who ran the chemical safety unit at the EPA for five years, and spent more than 20 years working there until he left the agency in January when President Trump took office, said he was disappointed by Mr. Pruitt\u0026#039;s action. \u0026#039;They are ignoring the science that is pretty solid,\u0026#039; Mr. Jones said.\u0022The decision is in line with Pruitt\u0026#039;s anti-science, pro-corporate stance. Yet advocates and researchers who have followed the years-long campaign to end the use of chlorpyrifos were still shocked by Pruitt\u0026#039;s outrageous move.We\u0026#039;re all a little stunned; poisoned produce and brain-damaged babies not as important to @EPA as corporate profits https://t.co/LXbw9eYHZx— carey gillam (@careygillam) March 30, 2017UPDATED: Trump\u0026#039;s EPA just approved a pesticide known to damage kids\u0026#039; brains. https://t.co/YQiXeYPNtt [not sure why this stuns me; it does]— Tom Philpott (@tomphilpott) March 30, 2017As a result of Pruitt\u0026#039;s decision, children and farmworkers nationwide are endangered, rights advocates and environmental groups charge.\u0022Without the ban, farmworkers, their children, and others can\u0026#039;t escape exposure because the poison is in [the] air they breathe, in the food they eat, the soil where children play,\u0022 observed Erik Nicholson, national vice president of United Farm Workers. \u0022We all have a basic right to a healthy life.\u0022Some further argued that the decision breaks the law.\u0022We have a law that requires the EPA to ban pesticides that it cannot determine are safe, and the EPA has repeatedly said this pesticide is not safe,\u0022 Patti Goldman, managing attorney at Earthjustice, told the New York Times.Earthjustice has vowed to fight Pruitt\u0026#039;s decision in court, reported NPR.
