The research program of the Aerosol Research Branch includes research grants and contracts at institutions in many parts of the United States, in addition to an intramural program. The purpose of these projects is to study the chemical and physical properties of aerosols, identify the mechanisms of aerosol formation and removal, and conduct experiments to measure these rates. The results of the research are being used (1) to establish the contribution of the various sources to the ambient atmospheric aerosol loading, (2) to characterize urban, natural, and primary and secondary aerosols, (3) to develop quantitative descriptions of the generation and removal rates associated with each major aerosol source and sink, (4) to quantify the effects of aerosol on atmospheric chemical reactions, and (5) as a scientific basis for recommending regulatory actions concerned with air quality improvements. The research projects funded under EPA's base program are described.
