Incomplete combustion is a well known source of polycyclic aromatic hydrocarbons(PAHs), however, limited data are available on emissions of particle-phase PAHs from motor vehicles, municipal solid waste incinerator, and commercial factory stacks in Korea. Particle-phase PAHs emissions were measured in Seoul, Korea, from March 2000 to April 2000. On-road vehicle samples were collected in two tunnels. Stationary samples were collected at two municipal solid waste incinerators and two industrial stacks
Sixteen particle-phase PAHs were quantified by GC/MS. The emission factors of total PAHs were 1.98ug/km and 2.52ug/km in Bookak and Namsan Tunnel. Pyrene, fluoranthene, and chrysene in total PAHs were important emission factors to control vehicle emissions. For stationary emissions, total PAHs emission factors from two municipal incinerators were 0.85ug/kg-fuel and 0.46ug/kg-fuel. The patterns of individual PAHs emission factors in both utilities were similar. The percentage of naphthalene and anthracene emission factors in total PAHs was abundant in comparison to other 14 PAHs. Total PAHs emission factor from the industrial facility using B-C oil was 0.74ug/kg-fuel and total PAHs emission factor from the industrial facility using LNG fuel was 0.26ug/kg-fuel. The patterns of individual PAHs emission factors in both facilities were not different with the patterns in two utilities.
In summary, Fluoranthene and benzo[a]pyrene which cause health effects were not detected from stationary emissions but detected from vehicle emissions. This study suggested that the control of vehicle emission might reduce possible health risk caused by carcinogenic PAHs.
