What the brain really thinks about forever chemicals
News

“It is thought that the shorter chain PFOAs are less toxic,” Cannon said. “But I would say we truly don’t know that. The data is not there. We have all these alternatives in the environment with little to no toxicity testing. In some cases that may be true. They may metabolize and leave the body faster, but from a neurological standpoint the smaller compounds usually penetrate the brain better. So that is something we need to pay attention to.”
