EPA releases draft safety levels for GenX, a PFAS chemical manufactured in North Carolina

Long-term exposure to GenX—a PFAS chemical compound made in North Carolina and used for making nonstick coatings—appears to be dangerous, even in minute amounts, according to draft findings released Wednesday by the Environmental Protection Agency. Animal studies cited by EPA show the potential of affecting the kidneys, blood, immune system, liver and developing fetuses.

The draft chronic reference dose for GenX is about 300 ppt, states STEEP’s Laurel Schaider, which is four times EPA’s chronic reference dose for PFOA and PFOS, the two chemicals that GenX was developed to replace after EPA called for their phase out due to human health impacts.
