Ecological Toxicity and Risk of PFAS in the Environment

The DoD is responsible for the management of installations impacted by per- and polyfluoroalkyl substances (PFAS) and understanding the ecological impact of these chemicals improves decision-making related to mitigation of exposures and future environmental cleanup. Over the years, efforts to close knowledge gaps in ecological toxicity and risk have aided in the development of appropriate site-specific risk assessments. This session addressed the ecological toxicity and risk of PFAS, and PFAS-free firefighting formulations on avian, aquatic, and terrestrial species.
