Abstract Number: 479 Working Group: Linking Aerosol Oxidative Potential with Chemical Composition and Biological Endpoints
Abstract People in cities are exposed to various types of particulate matter from numerous emission sources such as motor emissions, biomass burning aerosols and resuspended road dust. The biological effects of due to exposure to such particles may depend on chemical components in these particles and on the exposure extent. We will describe seasonal variations in the biological effects and oxidative potential of pollution particles from Beijing and of resuspended road dust from large cities in Europe. Specifically, we will describe in vivo and in vitro studies that highlight the interplay between oxidative stress, inflammation and activation of defense mechanisms in the overall biological effects of exposure to pollution
