AbstractConcentrations, sources and risk of 16 priority polycyclic aromatic hydrocarbons (PAHs) were investigated in surface sediments from 19 representative tributaries in a regional scale of Chongqing City. The total concentration of 16 PAHs (Sigma PAHs) ranged from 221 to 3205ngg(-1) with a mean of 1055ngg(-1). Most tributaries of the Jialing River exhibited significantly higher Sigma PAHs concentrations (mean 1864ngg(-1)) compared to those flowing into the Yangtze River (mean 787ngg(-1)). Isomeric ratio and hierarchical clustering analysis showed combustion may impact sedimentary PAHs at most center sites of the City, while PAHs at most sites were mixed of petrogenic and pyrogenic sources. Toxicity equivalency concentration for carcinogenic PAH were 2-4 times more than the Dutch limit. More comprehensive assessment of safety is suggested to reduce environmental risk of PAHs in sediments.
