This SERDP and ESTCP webinar focuses on DoD-funded research efforts to study PFAS bioaccumulation in aquatic species. Specifically, investigators will discuss impacts to marine food webs and benthic biota exposed to impacted marine sediments associated with aqueous film-forming foam (AFFF) impacts, as well as research on acute and chronic toxicity of PFAS-free foam alternatives. There will be three presentations titled: 1) "Factors Influencing PFAS Bioaccumulation and Biomagnification in Marine Food Webs Associated with AFFF Sources in a New England Estuary" 2) "Bioavailability, Bioaccumulation, and Toxicity of PFAS in Benthic Biota Exposed to Impacted Marine
Sediments" and 3) "The Relative Toxicities of Current Use AFFF and Next Generation Alternatives to Aquatic Species for Informing Risk Assessment".
