ABSTRACT- Organochlorines in fish muscle collected from coastal water and purchased from the local markets of Korea were quantitatively determined. In addition, fish consumption risk assessment was carried out for human. Polychlorinated biphenyls (PCBs) and DDTs were the predominant contaminants whose concentrations ranged from 2.96 - 96.6 ng/g and 0.84 - 27.0 ng/g (wet weigh basis), respectively. The highest PCB concentration was found near the industrial complex. Hexachlorocyclohexane, chlordane-related compounds, and hexachlorobenzene concentrations were relatively low ranging 0.64 - 5.6 ng/g, 0.17 - 4.24 ng/g, and 0.08 - 1.58 ng/g, respectively. The collected fish showed approximately two times higher concentrations of PCBs and DDTs than the purchased ones, which means that recreational fisher have high latent possibility of exposure to organochlorine compounds. Risk-based screening value (SV) was calculated by using the EPA approach to identify the primary chemical of concern. Total PCB concentrations in all collected and purchased samples exceeded the SV value (6.49 ng/g), but the other compounds were mostly below the each SV value. Based on the estimated screening values, PCB compounds were identified as potential chemicals of concern throughout the coast of Korea.
