Huffington Post: Dr. Jennifer Lowry shares concerns after refusal to ban brain-damaging pesticide

EPA Chief refused to ban the pesticide after his own agency scientists found the chemical can cause irreversible harm

Defying the recommendation of his own agency’s scientists, Environmental Protection Agency Administrator Scott Pruitt has refused to ban a widely used pesticide that’s been linked to learning disabilities in children.

Pruitt’s order allows chlorpyrifos, an organophosphate insecticide that’s been used on crops from broccoli to cranberries since the 1960s, to remain on the market for agricultural use. The EPA proposed in November 2015 under the Obama administration to permanently ban the chemical on food crops, citing potential risks to human health. The move stemmed from a 2007 petition filed by the Natural Resources Defense Council and the Pesticide Action Network North America.

Critics condemned Pruitt and President Donald Trump for showing they value corporate profits over public health. The move, less than two months after Pruitt was confirmed as the nation’s top environmental officer, signals far looser regulation of harmful substances under the Trump administration.

“If the new administration is willing to support corporate interests over public safety in the face of such strong scientific evidence, then we should expect clear sailing for many other questionable pesticides in the future,” Carey Gillam, a HuffPost contributor and research director for U.S. Right to Know, a nonprofit consumer advocacy group, told The Huffington Post in an email.

Pruitt, a lawyer who has shown disdain for scientific research, said the Obama-era proposal to ban the pesticide relied largely on studies “whose application is novel and uncertain, to reach its conclusions.”

“We need to provide regulatory certainty to the thousands of American farms that rely on chlorpyrifos, while still protecting human health and the environment,” Pruitt, a longtime antagonist of the agency he now leads, said in a statement. “By reversing the previous Administration’s steps to ban one of the most widely used pesticides in the world, we are returning to using sound science in decision-making — rather than predetermined results.”

Chlorpyrifos, also known by its trade name Lorsban, is used in nearly 100 countries on more than 50 different crops, including corn, soybeans, cranberries and broccoli. Produced by Dow Chemical Co., it was largely banned in 2000 for at-home use in the U.S., but continues to be widely used on thousands of American farms.

Sheryl Kunickis, director of the the U.S. Department of Agriculture’s Office of Pest Management Policy, was among those who applauded Pruitt’s decision, which she said was “grounded in evidence and science.”

“It means that this important pest management tool will remain available to growers, helping to ensure an abundant and affordable food supply for this nation and the world,” Kunickis said in a statement.

Dow called it the “right decision for farmers” and said the chemical giant “remains confident that authorized uses of chlorpyrifos products offer wide margins of protection for human health and safety.”

Annual testing reports by USDA show chlorpyrifos residues in nectarines, peaches, cucumbers and other crops. Even low-dose exposure to organophosphates, particularly in the womb, has been found to harm brain development in children, leading to higher risk of disorders like autism.

For years, environmental groups and medical professionals have pushed for an all-out ban on the chemical. In a January letter to EPA, dozens of doctors, nurses and professors urged the agency to revoke all tolerances of chlorpyrifos in food.

“Children especially experience greater exposure to organophosphate pesticides due to their increased hand-to-mouth action, and relative to adults they eat more fruits and vegetables, drink more, and breathe more,” the letter states. “With each year of delay in cancelling food tolerances and agricultural and other uses of chlorpyrifos, more children are unnecessarily at elevated risk for problems in learning, social skills, motor function, and other developmental domains.”

Jennifer Lowry, a pediatrician and toxicologist at Children’s Mercy Kansas City and chair to the Council on Environmental Health for the American Academy of Pediatrics, told HuffPost she was “deeply troubled” by Pruitt’s decision, which she said denies science that chlorpyrifos causes irreversible harm to children. Multiple studies, she said, have shown that children exposed to organophosphate pesticides, such as chlorpyrifos, have an increased risk for abnormal neurodevelopment, including persistent loss of intelligence and behavior problems.

Lowry added that Pruitt’s decision allows the continued exposure of Americans to a substance that will harm children.

The Natural Resources Defense Council, the Pesticide Action Network North America, and Earthjustice have vowed to fight the EPA in court.
