Priority PAHs recommended by USEPA were all detected, and the mass concentrations of individual PAHs was between 1.49 and 87.43ngg^(-1), The PAHs with low molecular weight, such as Nap, Flu, Ace were observed in relatively low mass concentrations. The PAHs with high molecular weight, such as Chrysene, Indeno [1, 2, 3-cd] pyrene, Benzo perylene were relatively abundant and the mass congcentration of BghiP was the highest. The total mass congcentration of 16 PAHs exceeded standard of Holand from 10 to 40 times, and in middle pollution level comparatively with other districts.
