Abstract

The residue levels of total PCBs in the surface samples were detected low concentration compared to the coastal area in Korea, and the PCBs pattern were very similarly to the arochlor mixture(1016+1232+1248+1260). The selected area divided into three area(Kanghwa:A, Yellow:B and Jangdo:C) by depending on the chlorine ratio. The PCBs were mainly detected dichlorinated and trichlorinated biphenyls in far sea, and heptachlorinated and octachlorinated biphenyls in the near the Incheon coastal area. The residue levels of PCBs were detected 0.72${\sim}$9.20 ng/g in the surface samples, 1.60~3.00 ng/g for Kanghwa and 0.34~9.20 ng/g for Jangdo in the core samples, and the PCBs concentration increased from bottom to top.
