Toxic chemicals called PFAS are in pesticides sprayed on food and included in pet flea treatments and home bug repellants, a new study found.
Called “forever chemicals” because of how long they remain in the human body and environment, perfluoroalkyl and polyfluoroalkyl substances, or
in pesticides used in both agricultural and residential pest control, including pet flea treatments. “This is really the first study in the US to comprehensively look at how pesticides can be contributing to global contamination that scientists see occurring in our waterways.” The , the chemicals are not often considered in federal pesticide regulatory efforts or in toxicologic evaluations of pesticides, said Stephanie Eick, an environmental and reproductive epidemiologist and assistant professor at Emory University in Atlanta. She too was not involved with the new study. “The regulations surrounding pesticides are currently outdated and ineffective, so this discovery of
ingredients from pesticide manufacturing, the spokesperson added. The American Chemistry Council, an industry association, told CNN that pesticides are among the most stringently regulated products in the United States. “We would need time to review closely, but it appears these researchers are lumping many pesticides in as
components to pesticides because it also increases the stability of the pesticide in the fields,” he said. “The pesticide is less likely to be broken down as quickly, and so it can stay effective for a longer period of time without reapplication.

New method to degrade PFAS 'forever chemicals' found effective in the labPer-and poly-fluoroalkyl substances (PFAS) are known as 'forever chemicals' because they are notoriously resistant to degradation. Due to their stable chemical structure, PFAS—which are found in thousands of variants—are used in oil and grease-resistant food packaging, non-stick cookware, cosmetics, clothing, and fire-fighting foams.
