The overall objective of this study is the development of refined probabilistic exposure models for particulate matter (PM) suitable for predicting PM10 and PM2.5 exposure of an urban population. New statistical methods will be used in the development of the PM exposure models that will incorporate both the variability and the uncertainty in the relevant exposure factors. Specifically, these models will include time-activity data to account for the way people interact with their environment as a function of time, location and outdoor conditions. These models will also account for the way PM pollution is spatially dispersed relative to the various urban area ambient monitors. In the course of building PM exposure models, new measurements, mostly in non-residential micro environments, will be made when critical concentration data are lacking. The development of these improved, user-friendly PM exposure models will provide better capability to set, more rational and defensible National Ambient Air Quality Standard (NAAQS) for particulate matter, PM10 and PM2.5. Moreover, this work will also prove valuable for improving the power of epidemiological studies of the impact of PM pollution on mortality and morbidity.
