Surface soils sampled at several sites in Seoul, Korea were analyzed to determine the concentrarions and distributions of PAHs. Results are as follow; 1) The Bap concentration in soils was found to be the highest in the industrial area (128 ng/g) and lowest in the residential area(19 ng/g). 2) The Py concentration in soils was highest in the tunnel area (1,110 ng/g) and the lowest in the Achasan area(18 ng/g). 3) The BghiP concentration in soils was higher in road (538 ng/g) and tunnel (532 ng/g) areas than in others areas. 4) It was shown that the PAHs concentrations in residential areas were affected by combution of fossil fuel, those in industrial, road, tunnel, terminal and commercial areas were affected by vehicle exhaust.
