Determination of Polycyclic Aromatic Hydrocarbons in Airborne Particulate Matter in Goeteborg

摘要

During February 1978 particulate samples of urban air were taken at the Swedish Water and Air Pollution Research Institute's sampling stations in central Goteborg and at Rorvik, about 40 km south of Goteborg. The difference in source and age is reflected in the PAH-profiles, that is, the distribution of individual PAH. In the profile of the locally emitted PAH, the ratio between indeno (1,2,3-cd) pyrene and benzo(ghi) perylene indicates motor traffic and fuel combustion to be the main sources. Working up data of soot and PAH in accordance with Spearmann's ranking method gives a good correlation between the concentrations of PAH and soot (OECD-method).
