EPA Webinar on Human Health Toxicity Assessment for GenX Chemicals
EPA will host a webinar on Friday, November 12, 2021, from 10:00 – 11:00 am (eastern time) to provide an overview of the, “Final Human Health Toxicity Assessment for Hexafluoropropylene Oxide (HFPO) Dimer Acid and its Ammonium Salt (GenX Chemicals).” This assessment focuses solely on the potential human health effects associated with oral exposure. It provides hazard identification, dose-response information, and derives oral reference doses (RfDs) for chronic and subchronic exposures using new data and uncertainty factors which resulted in lowering the toxicity value to be more protective than EPA’s 2018 draft toxicity assessment for GenX. EPA will use this information to develop a national drinking water health advisory for GenX, to be published in Spring 2022. For more information about the toxicity assessment, visit EPA’s website.
