Impact/Purpose:
The National Exposure Research Laboratory (NERL) Human Exposure and Atmospheric Sciences Division (HEASD) conducts research in support of EPA mission to protect human health and the environment. HEASD research program supports Goal 1 (Clean Air) and Goal 4 (Healthy People) of EPA strategic plan. More specifically, our division conducts research to characterize the movement of pollutants from the source to contact with humans. Our multidisciplinary research program produces Methods, Measurements, and Models to identify relationships between and characterize processes that link source emissions, environmental concentrations, human exposures, and target-tissue dose. The impact of these tools is improved regulatory programs and policies for EPA.
Description:
Worldwide attention has recently been focused on Per- and Polyfluorinated Alkyl Substances (PFAS) due to the growing body of evidence indicating that many of these compounds are toxic, bioaccumulative, and persistent in the environment. Advances in analytical chemistry have played the key role in our developing understanding of how these compounds behave in the environment, how organisms and people become exposed, and what risks may be associated with their occurrence.
