Atmospheric particulate matter in urban areas include carbon as a major component. Particulate organic carbon (POC) may be emitted directly by stationary and mobile sources. However, a large fraction of the urban POC is formed in-situ by reactions involving gas phase hydrocarbons. These hydrocarbons react with the hydroxyl radical (olefinic HC also react with ozone) to form a complex mixture of reaction products, some of which are not volatile and condense as aerosols. Volatility considerations indicate that most lower molecular weight (MW) hydrocarbons react in polluted air to yield products that remain in the gas phase. Aerosol formation is expected to become substantial for higher MW hydrocarbons with at least 7-8 carbon atoms. Thus, this study focuses on three representative C{sub 7}-C{sub 8} hydrocarbons, namely the paraffin n-octane, the olefin 1-octene, and the cyclic paraffin methylcyclohexane.
