Abstract
Surface sediments, suspended particulate matters (SPM) and surface waters were collected from Lake Shihwa and coastal areas of Kyeonggi Bay, Korea and were analyzed for polycyclic aromatic hydrocarbon (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCP). Relatively high concentrations of PAHs were found in the sediment samples from S1 to S3, which were located near harbor areas. Combustion of fossil fuel was thought to be the main sources of PAHs in the sediments from Lake Shihwa and coastal areas of Kyeonggi Bay. Total PAH concentrations in the sediments showed a significant positive correlations with total organic carbon (TOC), while no correlations could be found between the concentrations of PAHs and TOC in surface water. It was shown that resuspension of the sediments and flushing effects by tidal current can be an important factor to control contaminants levels in the coastal areas of Kyeonggi Bay. PAHs, PCBs and OCP concentrations in sediments from this study area were relative lower than other industrialized coastal area in Korea. PCA analysis of PCB concentrations in the sediments showed a discriminate congener specific compositional difference among the sampling sites.
