Description / Table of Contents:
Atmospheric particulate matter (PM) is known to have far-ranging impacts, from human health to climate forcing. The characterization of emission sources and the quantification of specific source impacts to PM concentrations significantly enhance our understanding of and our ability to eventually predict the fate and transport of atmospheric PM and its associated impacts on humans and the environment. The source apportionment of PM has been realized through combinations of chemical analysis (of elemental tracers, particle size, isotopic composition, and organic composition via unique tracers and molecular fingerprints) and numerical modeling (e.g., diagnostic source ratios, chemical mass balance modeling, positive matrix factorization, and Monte Carlo simulations).
Recent advances in source apportionment applications have contributed unique combinations of chemical and numerical techniques for determining the contributions of specific sources, including diesel exhaust and biomass burning. These advances also identify and help characterize the contributions of previously uncharacterized sources. Numerical modeling has also enabled estimations of contributions of emission sources to atmospherically processed PM in urban and rural regions.
