Distributions of 16 PAHs and 82 PCBs (including dioxin-like PCBs, DL-PCBs, and non-dioxin-like PCBs, NDL-PCBs) were investigated in sediment and seafood samples collected from the Gunsan coast, Korea. Total PAH (Σ16PAH) concentrations in sediments were in a range of 0.09~108 (mean: 57.9) ng/g-dry and gradually decreased outwardly. PAHs in marine sediments were originated from both combustion processes and petroleum sources. The total PCB (Σ82PCB) concentrations in sediments were in a range of nd (not detected)-0.64 (mean: 0.27) ng/g-dry, and DL-PCB (Σ12 dioxin-like PCB) were in a range of nd-0.293 (mean 0.054) pg-TEQ/g-dry. DL-PCB concentrations were correlated with NDL-PCB concentrations. In this study, the concentrations of PAHs and PCBs in marine sediments did not exceed the ecotoxicological values. Total PAH concentrations ranged from nd to 24.3 (mean: 5.35) ng/g-wet, benzo[a]pyrene (BaP) was not detected in seafood samples and the concentrations of Σ4PAH (BaP, chrysene, benzo[a]anthracene, and benzo[b]fluoranthene; nd-18.5 ng/g-wet) were lower than the maximum level (30 ng/g-wet) set by EU. The concentrations of NDL-PCBs in seafood samples were in a range of nd-0.19 (mean: 0.08) ng/g-wet less than 1% of the EU-set maximum level. The DL-PCB concentrations were below 0.1 pg-TEQ/g-wet, less than 1% of the EU-set maximum level. Human risk assessment of PAHs and PCBs via seafood consumption was carried out, and both lifetime cancer risk and non-cancer risk were low.
