Characterization of PAHs Contamination in Soils from Metropolitan Region of Northern China

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 μg kg⁻¹. The mean and median concentrations of 16 PAHs were 1040.8 and 626.7 μg kg⁻¹, r...

Description
Summary: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 μg kg⁻¹. The mean and median concentrations of 16 PAHs were 1040.8 and 626.7 μg 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 μg kg⁻¹.
