MOBILE SOURCES OF ATMOSPHERIC POLYCYCLIC AROMATIC HYDROCARBONS: A ROADWAY TUNNEL STUDY

Suspended particulate matter samples were collected by high volume samplers in a heavily traveled roadway tunnel to characterize the mobile source emissions (diesel- and gasoline-fueled vehicles) for polycyclic aromatic hydrocarbons (PAHs). Liquid and gas chromatographic techniques were employed to isolate and quantify individual PAHs in dichloromethane extracts of Teflon and glass-fiber filters. Mobile-source PAH emission estimates were generated from the particle- and vapor-phase samples collected in the tunnel and agree with emission estimates reported previously for roadway tunnels in Japan. Factor analysis of PAH concentrations from 47 filter samples yielded two factors; one of which possibly represented the diesel-fueled vehicles (heavy-duty trucks) and the other, either gasoline-fueled vehicles or a composite of the gasoline and diesel sources.
