The United States Environmental Protection Agency's (EPA) National Exposure Research Laboratory is developing improved methods for modeling the source through the air pathway to human exposure in significant microenvironments of exposure. As a part of this project, the authors developed a microscale emission factor model for predicting real-world real-time motor vehicle particulate matter PM(sub 10) and PM(sub 2.5)(MicroFacPM) emissions, which uses available information on the vehicle fleet composition. This paper presents the use of MicroFacPM to calculate the contribution of PM(sub 2.5) per vehicle class, age-wise, gasoline, diesel, brake wear and tire wear sources. The contribution of emission factors is presented for two scenarios: first the Tuscarora Mountain Tunnel, on the Pennsylvania Turnpike, PA and second for Capital Boulevard, in Raleigh, NC.
