Determination of Key Organic Compounds Present in the Particulate MatterEmissions from Air Pollution Sources

摘要

The purpose of the research is to provide a molecular characterization of theprimary organic particulate matter emitted from urban pollution sources, to provide parallel data on the concentration of these compounds found in ambient air, and to use this information to compare emissions data to air quality data for many organic compounds. A dilution source sampling system was employed to collect primary fine aerosol emissions from 18 major urban source types that contribute close to 80% of the fine organic aerosol emitted in the Los Angeles area. Ambient fine particle samples were collected for one entire year at four urban locations and at one remote offshore sampling site. The identification and quantification of organic compounds present in these samples has been conducted
