Impact/Purpose:
The National Exposure Research Laboratory′s (NERL) Human Exposure and Atmospheric Sciences Division (HEASD) conducts research in support of EPA′s mission to protect human health and the environment. HEASD′s research program supports Goal 1 (Clean Air) and Goal 4 (Healthy People) of EPA′s 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:
Perfluorinated compounds (PFCs) have been used extensively in consumer and industrial products and are not found in environmental and biological samples around the world. Recent research suggests that fish consumption may be an important human exposure pathway to perfluorooctane sulfonate (PFOS). In response to growing interest in human exposure to Perfluorinated compounds (PFCs) the state of Minnesota (MN) has made measurements of PFCs in fish collected in the Minneapolis-St. Paul area. Some elevated levels of PFOS have been found, and the state has issued fish consumption advisories to limit potential exposures. To better describe the geographical distribution of PFC contamination and to more fully evaluate potential sources in MN, composite fish samples were collected from 59 lakes and several areas along the Mississippi River in 2007. Samples were analyzed using a recently evaluated method using solid phase extraction (SPE) and LC/MS/MS.
