| ABSTRACT |
|
In this study, physico-chemical properties and heavy metal contents of sediment samples were determined to characterize the current pollution levels of the sediments. Ignition loss of the samples obtained from outside of the harbor was relatively lower than that from the samples obtained inside of the harbor. Heavy metal pollution was not serious except Ni. Concentrations of Ni for J1, J3, and J4 exceeded 16 mg/kg. Thus, these areas were classified as lowest effect level according to Ontario sediment quality guidelines. Evaluation of sediments pollution using Igeo and R resulted as non-pollution for all considered metals, which indicated that no outer pollutants entered in the Jeju outport harbor. However, drastic increase of Cu concentrations was observed. Its concentration obviously increased toward the inside of the outport harbor. Therefore, careful attention and plan for the protection and remediation of sediments is required to maintain the cleanness of the Jeju outport harbor. |
