Zhoushan Archipelago and the adjacent Xiangshan Harbor are important commercial, tourism, fishing, and mari-culture areas. Considering the concern on the effects of anthropogenic activities on the environment, the level and source apportionment of polycyclic aromatic hydrocarbons (PAHs) in surface sediments were investigated. The sum of 16 PAH (S16 PAH) concentrations in the Zhoushan Archipelago ranged from 3.67 to 31.30 ng g-1 d.w., with a mean of 15.01 ± 1.21 ng g-1 d.w., and that in Xiangshan Harbor varied from 11.58 to 481.44 ng g-1 d.w., with a mean of 62.52 ± 32.85 ng g-1 d.w. Diagnostic ratios and factor analysis were per-formed to identify PAH sources. Results show that PAHs have mixed origins (i.e., traffic-related sources, coal combusion, petrogenic sources, and biomass buring), with pyrolytic-related pollution as the dominant source. This study provided a baseline to promote environmental protection and pollution episode monitoring in the East China Sea.
