Abstract: Real-world vehicle emission factors for seventeen gas and particulate polycyclic aromatic hydrocarbons (PAHs) were quantified in the Shing Mun Tunnel, Hong Kong during summer and winter 2003. Naphthalene, acenaphthylene, and acenaphthene were the most abundant gas PAHs while fluoranthene and pyrene were the most abundant in the particle phase. Most (98%) of the gas PAHs consisted of two- and three-aromatic rings whereas most of the particle-phase PAHs were in four- (?60%) and five-ring (?17%) for fresh exhaust emissions. Average emission factors for the gas- and particle PAHs were 950-2564??gg?veh-1?km-1 and 22-354??gg?veh-1?km-1, respectively. Good correlations were found between diesel markers (fluoranthene and pyrene; 0.85) and gasoline markers (benzo(ghi)perylene and indeno(1,2,3-cd)pyrene; 0.96). High
