Abstract

This study involved a comprehensive investigation of heavy metals and polycyclic aromatic hydrocarbons (PAHs) in seawater, sediments, and seafoods in an important open fishing area connecting China and Japan. Cu, Pb, Cd, Cr, As, and PAHs were detected in all the studied environmental media. Specifically, Pb and low molecular weight PAHs (LMW-PAHs) were observed at high levels, due to intensive ship activities and accidental crude oil spills. Additionally, source diagnosis of PAHs suggested a potential impact from combustion. Bioaccumulation factors (BAFs) and biota-sediment accumulation factors (BSAF) suggested moderate or low bioaccumulation potentials of the analytes from water and sediments, respectively. Noncarcinogenic risk assessment, based on target hazard quotients (THQs), indicated a potential low risk by consuming the studied seafoods, while the incremental lifetime carcinogenic risk assessment (ILCRs) suggested “acceptable risk” or “potential risk.” However, it should be noted that there have been possibilities that the carcinogenic risk could be elevated due to bioaccumulation of the PAHs in the seafoods after long-term exposure. In summary, it is necessary to evaluate the seafood security carefully in this open fishing area due to the potential health risks.
