Toxicity of PFAS to Aquatic Biota: A Literature Review (WP-21-03)

Per- and polyfluoroalkyl substances (PFAS) are a group of high-performance chemicals used in some firefighting applications and to impart properties such as water and stain resistance to various products. Many PFAS are persistent in the environment and are of interest due to their toxicity profiles. This report summarizes the state of knowledge regarding the toxicity of PFAS to aquatic organisms and identifies knowledge gaps that could potentially be filled by targeted studies.
