| Peysistent oyganochlorine compounds (OCs) weve determined in sediments and bivalves from Gwangyang Bay. The concentrations of ¢²PCB, ¢²DDT, ¢²HCH and ¢²CHL in sediments were in the range of f 2.25¡11.4 ng g$^$-1/, 0.16¡1.16 ng g$^$-1/, nd¡0.51 ng g$^$-1/, and 0.05¡0.79 ng g$^$-1/, respectively. The overall OCs concentrations in sediments were below the effect range -median (ER-M) values toy benthic organisms suggested by NOAA (1991). Levels of PCB compounds a re relatively lower than other industrialized bays (Pusan Bay, Ulsan Bay, and Youngil Bay). OCs accumulated in bivalves were higher than those in sediments. In bivalves, the concentration ranges of ¢²PCB, ¢²DDT, ¢²HCH and ¢²CHL were 9.97¡31.7 ng g$^$-1/, 7.54¡22.6 ng g$^$-1/, 0.49¡2.0 ng g$^$-1/, and 0.82¡7.32 ng g$^$-1/, respectively. Relatively high PCB concentrations in both environmental matrices are found at the inner bay than the outer part, indicating that the sources of PCBs were located inside the bay. DDT compound showed relatively high concentrations in the vicinity of the mouth of river and urban area, whereas other organochlorine pesticides show homogeneous distributions over the bay. Homologue profile of PCB compounds shows that low-chlorinated congeners (especially, di-, tyi- and tetra-) are abundant in Gwangynng Bay, which is diferent from other areas in Korea. |
