PAHs and PCBs residues and consumption risk assessment in farmed yellow croaker (Larimichthys crocea) from the East China Sea, China

Large yellow croaker (Larimichthys crocea) purchased from five different farming sites in Zhoushan Archipelago and Xiangshan Harbor in the East China Sea, China were analyzed for polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). Concentrations of PAHs and PCBs in the edible muscle of L. crocea ranged from 83.14 to 174.68 ng/g wet weight (or 266.89 to 695.24 ng/g dry weight) and 3.89 to 17.40 ng/g wet weight (or 15.50 to 54.25 ng/g dry weight), respectively. Incremental lifetime cancer risk (ILCR) associated with the dietary intake of PAHs and PCBs in L. crocea was assessed. Results showed that levels of PAHs in L. crocea were high enough to cause potential carcinogenic risks for human consumption, while, levels of PCBs in fish samples were of low significant carcinogenic risk.
