Japan has emarged as a leading industrialized nation and an economic power in the world scene from the Far East. The rapid modernization and industrial growth have also left behind marks of environmental deterioration and incidents of human health effects. Considering organochlorine contaminants such as PCB, DDT arid HCH as markers of environmental quality, this introspective review examines the coastal health of Japan. A case study on these compounds in Seto-Inland Sea region in Japan revealed that the environmental load of persistent organochlorines, as typified by PCB is in coastal sediments. Temporal observations on these compounds in Japanese environment indicate that these classical pollutants have gradually decreased through years after restricting their usage. However, new environmental challenges are also recognized. Compounds such as Chlordane, TDCPP, PCDDs, PCDFs and coplanar PCBs still contaminate Japanese coastline. Environmental impact of exceptionally toxic PCDDs, PCDFs and related compounds in under strutinization.

To assess present status of polychlorinated biphenyls (PCBs) contamination in Kyeonggi Bay, Namyang Bay, and Lake Shihwa, 63 sediment samples were analyzed and applied to equilibrium partitioning approach. Sediment quality criteria (SQC) for exposure to Kanechlor mixture (KC-mix) was calculated as a value of 16 ${\mu}$g/g-organic carbon (OC). Two sites (Sites Kl8 and Kl9) within Incheon North Harbor (INH) with total PCBs concentrations 48 and 38 ${\mu}$g/g-OC, respectively, exceeded SQC, indicating a potential of adverse biological effects. The advantage and disadvantage of equilibrium partitioning approach has been discussed.
Butyltins in Surface Sediments of Kyeonggi Bay, Korea
Kim, Gi-Beum,Tanabe, Shinsuke,Koh, Chul-Hwan The Korean Society of Oceanography 1998 Journal of the Korean Society of Oceanography Vol.33 No.3
Forty sediment samples from Kyeonggi Bay, Korea were analyzed for butyltins, including tributyltin (TBT), dibutyltin (DBT), and monobutyltin (MBT) to determine their distribution and source in this area. Total butyltin concentrations in Kyeonggi Bay sediments ranged from 0.8 to 297 ng/g dry wt. with a mean value of 38 ng/g. The highest butyltin concentration was found in the innermost site in Incheon Harbor basin. The mouth of Han River had higher butyltin levels in sediments compared to open ocean. Butyltin levels correlated well with organic carbon content of sediment, but the major factor was the distance from the source area where antifouling paints were used for vessels and marine structures. Butyltin concentrations in the study area were lower than those reported for bays in other parts of the world. Considering the high toxic potential and sediment/water partition coefficient of TBT, further studies are needed to assess its biological effect in the marine ecosystem of Kyeonggi Bay.
