【 摘 要 】

This is a final report of work done in support of DOE interests in air quality assessment or managemnt and tropospheric aerosol chemistry. A central focus for the activities was support for the North American cooperative, NARSTO. Leaderrship and oversight was provided for NARSTO products including two major state-of-science assessments on airborne particles (particulate matter) and the fundamentals of pollutant emissions characterization. In addition, review sof so-called 'policy related air quality science were prepared addressing multi-scale atmospheric phenomena, snowpack chemistry and pollution, and North American aerosol baseline or background conditions. The relationship between the identification of pollution sourcees and human exposure to outdoor particles was investigated, and results critiqued. This work led to a major review of the integration of atmospheric chemistry, epedimiology and toxicology in linking airborne particles with human health effects. The last topical area of work in the project related to the carbon component of tropospheric aerosols. Work was done in support of a project to obtain samples of power plant effluents to estimate the carbon present in palnt emissions. The results suggsted only a minor amount of ambient particles were carbon from coal-fired plants. Another studied provided a conceptual plan for using isotopic carbon data to provide a vapor and condensed phase carbon balance for particles, including fossil and biogenic sources.
