Abstract
The present study characterized the distribution, sources as well as carcinogenic potency of PAHs in surface soil from metropolitan region of northern China. The total PAHs in topsoil ranged from 322.6 to 23244.7 microg kg(-1). The mean and median concentrations of 16 PAHs were 1040.8 and 626.7 microg kg(-1), respectively. Source analysis revealed that pyrogenic sources played a major role at the locations and pyrogenic PAHs were mainly from incomplete combustion of coal, biomass and petroleum. The calculated mean BaP-equivalent values for individual carcinogenic PAHs were 148.4 microg kg(-1).Entities:
