We measured various geochemical parameters including texture, chemical oxygen demand (COD), ignition loss (IL), acid volatile sulfide (AVS), nonmetallics, alkali metals, alkaline earth metals, transition elements and heavy metals in order to determine the characteristics of spatial distribution in the surface sediments collected from 19 stations in the Deukryang Bay. It was observed that chemical oxygen demand (COD) and acid volatile sulfide in most stations were below the criteria proposed by Japan Fisheries Resource Conservation Association (JFRCA) to evaluate the pollution status of marine sediment. The pollution level was estimated by Enrichment factor (Ef) and Index of geoaccumulation (Igeo). For elements, the Enrichment factors (Ef) were smaller than 1 except for arsenic (As) which had highest Ef value of 1.72 and the Index of geoaccumulation (Igeo) for nonmetallic and metallic elements ranged between 1 and 2, indicating that the pollution levels by these elements were not serious. However, for the sustainability of the Deukryang Bay, continous monitoring should be necessary for with these harmful elements.
