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:
Several methods have been used to account for measurement error inherent in using the ambient concentration of particulate matter < 2.5 µm (PM2.5, ug/m,3) as a proxy for personal exposure. Common features of such methods are their reliance on the estimated correlation between ambient and personal PM2.5 concentrations (r). However, extant studies of r have not been systematically and quantitatively assessed for publication bias or heterogeneity.
