Help Get Neurotoxic Pesticide, Chlorpyrifos, Out of Agriculture

(Beyond Pesticides, January 22, 2019) Earlier this month, U.S. Representative Nydia VelĂĄsquez (D-NY) introduced The Ban Toxic Pesticides Act, H.R.230 which bans the insecticide chlorpyrifos from commerce. Chlorpyrifos is a toxic chemical that has been linked to damaging and often irreversible health outcomes in workers, pregnant women, and children. As a result of a revised human health risk assessment, the Environmental Protection Agency (EPA) developed a regulation to ban chlorpyrifos in 2016. Under the Trump Administration, the EPA has taken steps to reverse the regulation. “It’s unconscionable for EPA to turn a blind eye as children and workers are exposed to this poison,” VelĂĄzquez said.  “If the EPA won’t do its job when it comes to chlorpyrifos, then Congress needs to act – and do so quickly.” Ask your U.S. Representative to Co-Sponsor H.R. 230 to Stop the Use of the Toxic Insecticide Chlorpyrifos, which Is Damaging Children’s Brains.  Chlorypyrifos is a widely used pesticide. Agriculture companies annually spray 6 million pounds of the substance on crops like citrus, apples, and cherries.  In the same family as Sarin gas, the substance was initially developed prior to World War II as a chemical weapon. It can overstimulate the nervous system to cause […]

California Criticized for Adopting Inadequate Measures to Restrict the Highly Toxic Chlorpyrifos

(Beyond Pesticides, December 4, 2018) In mid-November, the state whose agricultural operations used more than 900,000 pounds of chlorpyrifos in 2016 (down from two million pounds in 2005) moved to establish some temporary restrictions on its use. Regulators at the California Department of Pesticide Regulation (CDPR) issued interim restrictions on the compound while the agency works on a formal regulatory process to list chlorpyrifos as a “toxic air contaminant” and develop permanent restrictions on its use. A neurological toxicant, chlorpyrifos damages the brains of young children: impacts of exposure, even at very low levels, include decreased cognitive function, lowered IQ, attention deficit disorder, and developmental and learning delays. It was slated to be banned for food uses by the U.S. Environmental Protection Agency (EPA) last year, but the decision was reversed by the Trump administration. The interim measures in California include: banning aerial application of chlorpyrifos; ending its use on many crops — except for those determined to be “critical” by virtue of there being few, if any, alternatives (as determined by the University of California Cooperative Extension and listed on DPR’s website); establishing a quarter-mile buffer zone for 24 hours after any application of the pesticide; and requiring a 24/7/365, 150-foot […]

Evaluation Used to Support Registration of Neurotoxic Chlorpyrifos Found To Be Fundamentally Flawed

(Beyond Pesticides, November 20, 2018) Scientific conclusions used to support the registration of the insecticide chlorpyrifos were flawed and omitted key health impacts, according to a fresh analysis of the original data by a team of independent scientists from northern Europe and the U.S. This re-review not only casts further doubt on the safety of the neurotoxic chlorpyrifos, it highlights a major flaw within federal pesticide regulation that allows pesticide producers to submit their own safety evaluations to the U.S. Environmental Protection Agency without public oversight. “One conclusion we draw is that there is a risk that the results of industry-funded toxicity tests are not reported correctly,” says co-author Axel Mie, PhD. “This makes it difficult for the authorities to evaluate the pesticides in a safe and valid way.” In both the U.S. and European Union, pesticide producers contract with laboratories to perform required safety tests of active ingredients they hope to register for use. While these studies are generally considered ‘confidential business information’ and not available to the public, using Swedish freedom of information laws, researchers were able to obtain two key studies relating to the developmental neurotoxicity of chlorpyrifos. Although not disclosed within the study, it is well […]
