PhotoAs environmentalists are learning, the Trump administration takes a very different approach to environmental matters than its predecessor.

At midweek, the Environmental Protection Agency (EPA) denied a petition to ban the use of chlorpyrifos, a widely used pesticide in agriculture. Under the Obama administration, the EPA had planned to impose a rule that would have effectively banned its use, citing research linking it to damage to the central nervous system.

Because of a court order, the current administration said it had until the end of this week to decide whether or not to ban the chemical, as environmental groups had filed suit to force it to do. EPA Administrator Scott Pruitt announced the agency would not ban the pesticide as he issued an EPA Order.

“In this Order, EPA denies a petition requesting that EPA revoke all tolerances for the pesticide chlorpyrifos under section 408(d) of the Federal Food, Drug, and Cosmetic Act and cancel all chlorpyrifos registrations under the Federal Insecticide, Fungicide and Rodenticide Act,” Pruitt wrote. “The petition was filed in September 2007 by the Pesticide Action Network North America (P ANNA) and the Natural Resources Defense Council (NRDC).”

The petition was never formally acted upon during Obama's two terms, but in 2015 the administration announced its intentions to impose rules that would not allow for any trace residues of the chemical on food. In announcing his decision to deny the petition, Pruitt said it was based on science rather than “pre-determined results.”

Environmental groups react

“EPA turned a blind-eye to extensive scientific evidence and peer reviews documenting serious harm to children and their developing brains, including increased risk of learning disabilities, reductions in IQ, developmental delay, autism and ADHD,” said Miriam Rotkin-Ellman, Senior Scientist at NRDC.

Kristin Schafer, policy director at PANNA, accused the EPA of caving to corporate pressure and of failing “to follow overpowering scientific evidence of harm to children’s brains.”

According to a pesticide information network, established by Cornell and several other universities, Chlorpyrifos is known as a broad spectrum insecticide. It was introduced in 1965 and used primarily to kill mosquitoes, but it's no longer approved for that use.

It is effective at controlling a variety of insects and is currently used on both food and non-food agricultural products.

The network also notes the chemical is “moderately toxic to humans.” It says studies have show that poisoning from chlorpyrifos may affect the central nervous system, as well as the cardiovascular system, and the respiratory system.
