Last Thursday (June 21), the Agency for Toxic Substances and Disease Registry (ATSDR) within the Centers for Disease Control and Prevention (CDC) released for public comment a draft Toxicological Profile of 14 perfluoroalkyls (PFAS). PFAS chemicals are used to make nonstick and waterproof products.
The draft report includes data suggesting that these chemicals pose a greater risk to human health than previously realized. ATSDR is advocating safe concentrations to be seven to ten times lower than EPAs previous guidelines. EPA originally considered PFAS under 70 parts per trillion (ppt) to be safe. CDC believes that numbers should be around 10 ppt.
The public comment period on the ATSDR Profile ends July 23, 2018.
