[Public comment] Draft scientific opinion on the risks to human health related to the presence of perfluoroalkyl substances in food
Policy
24 Feb 2020
The European Food Safety Authority is holding consultation for the proposed PFOA+PFOS+PFHxS+PFNA tolerable weekly intake of 8 ng/kg of body weight per week. Parts of the European population exceed this level with fish, fruit, and eggs being the largest sources of exposure. Comment period ends on April 20, 2020.

What the brain really thinks about forever chemicals
News
4 Feb 2020 | Purdue News Service
“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.”
