Abstract

Fine aerosol emissions have been collected from a variety of urban combustion sources, including an industrial boiler, a fireplace, automobiles, diesel trucks, gas-fired home appliances, and meat cooking operations, by use of a dilution sampling system. Other sampling techniques have been utilized to collect fine aerosol samples of paved road dust, brake wear, tire wear, cigarette smoke, tar pot emissions, and vegetative detritus. The organic matter contained in each of these samples has been analyzed via high-resolution gas chromatography. By use of a simple computational approach, a quantitative, 50-parameter characterization of the elutable fine organic aerosol emitted from each source type has been determined. The organic mass distribution fingerprints obtained by this approach are shown to differ significantly from each other for most of the source types tested, using hierarchical cluster analysis.

We gratefully acknowledge the many groups who made the source sampling experiments possible, including the personnel at Caltech’s Central Plant (boiler experiments), Housing Office (fireplace and home appliance experiments), and Physical Plant (sampling of road dust, brake dust, and roofing tar pot); the staff of the California Air Resources Board’s Haagen-Smit Laboratory in El Monte, CA (automobile and truck dynamometer tests); the employees of Continental Food Service in Pasadena, CA (meat-cooking experiments); and the staffs of the Los Angeles County Arboretum, Rancho Santa Ana, and Eaton Canyon Park (vegetation sampling). Lynn Salmon assisted in the development of the vegetation sampling protocol and in the collection of the leaf samples. Michael Jones and Heather Mason assisted in GC database management. Ken McCue provided valuable guidance on error analysis.
