Understanding PFAS Toxicity in Aquatic Ecosystems

Created using ChatSlide

This lecture examines the aquatic toxicity of PFAS, emphasizing PFOS and PFOA effects on fish and amphibians. It compares evidence across zebrafish, medaka, minnows, marine species, Xenopus, and Rana, addressing developmental, reproductive, immune, hormonal, oxidative, hepatic, and genetic damage. The presentation also explores mixture toxicity, species-specific sensitivity, tissue accumulation, and the variable risks of PFAS substitutes. It concludes by connecting internal and external...
