This study evaluated the level of PAH pollution in typical contaminated coking sites in Shenyang. Sixty surface soil samples were collected from an area of 1.3 × 10(5) m(2) polluted by PAHs. The concentrations, sources and possible health risks of 16 PAHs in the area were analyzed. The average content of Σ16 PAHs was 6.1 × 10(3) mg/kg. In oral intake, benzo(a)pyrene (BaP) presented the largest exposure risk (hazard quotient HQ = 1.17 × 10(-5)), followed by dibenz(a,h)anthracene (DbA) (HQ = 1.14 × 10(-5)). The non-carcinogenic hazard indices and carcinogenic risks of the PAHs were arranged in the order of BaP > DbA > benzo(b)fluoranthene (BbF) > benz(a)anthracene (BaA) > indeno(1,2,3-cd)pyrene (InP) > benzo(k)fluoranthene (BkF) > chrysene (Chr). Bap and DbA were the principal pollution sources, followed by BbF, BaA, InP, BkF and Nap successively. Oral intake was the main route of PAH entry into the human body.
