The regulation of fluorinated products just got a lot closer this week. The American
Chemical Society has published an article calling for governments to regulate and ban non-essential use of PFA (poly fluorinated alkyl) compounds due to their "extreme persistence and potential for harm". In "The Scientific Basis for Managing PFAs as a Class", researchers point to the the toxicity and extreme longevity of these "forever chemicals" as a threat to human health for the next 100 years. Extreme persistence and bioaccumulation is why PCBs were regulated in the 1970s; manufacturers who used PCBs spent billions of dollars cleaning those forever chemicals out of their factories and replacing equipment that had been filled with them. That fate for PFAs just got a lot closer.
