Assessment of the Health Impacts of Particulate Matter Characteristics

Research Report 161,
2012

This report describes a study by Dr. Michelle Bell of Yale University to evaluate the effects of exposure to components of the PM2.5 mixture on short-term morbidity and mortality, using data on 52 components of PM2.5 for 187 US counties. The report explores regional and seasonal variation in the chemical composition of PM2.5 and whether this variation affects the association between short-term exposure to PM and health effects. This study was funded under the Walter A. Rosenblith New Investigator Award.
