We studied the source, concentration, spatial distribution and health risk of 16 polycyclic aromatic hydrocarbons (PAHs) in urban soils of Beijing. The total mass concentration of 16 PAHs ranged from 93 to 13 141 mu g kg(-1) with a mean of 1228 mu g kg(-1). The contour map of soil PAH concentrations showed that the industrial zone, the historical Hutong district and the university district of Beijing have significantly higher concentrations than those in remainder of the city. The results of sources identification suggested that the primary sources of PAHs were vehicle exhaust and coal combustion and the secondary source was the atmospheric deposition of long-range transported PAHs. The incremental lifetime cancer risks (ILCRs) of exposing to PAHs in the urban soils of Beijing for adult were 1.77 x 10(-6) and 2.48 x 10(-5), respectively under normal and extreme conditions. For child, they were 8.87 x 10(-7) and 6.72 x 10(-6), respectively under normal and extreme conditions. Crown Copyright (C) 2010 Published by Elsevier Ltd. All rights reserved.
