발전소 가동에 따른 퇴적물내 중금속원소의 오염 가능성을 알아보기 위하여 삼천포화력발전소와 영광원자력 발전소 주변해역의 표층퇴적물을 대상으로 중금속 함량 분석을 실시하였으며 선정된 일부 퇴적물에 대해서는 화학적 존재형태를 파악하기 위해 연속추출분석을 실시하였다. 퇴적불 중의 금속원소 함량 분포는 대체적으로 평균입도에 의해 조절되고 있으며 탄산염 함량 및 유기불 함량에 의해서도 영향을 받고 있는 것으로 나타났다. 또한 화학적 존재형태별 분석에서도 Mn을 제외한 대부분의 중금속이 잔류상으로 존재하고 있어 인위적인 오염에 의해서라기 보다는 자연적인 분산에 의해 존재하고 있는 것으로 나타났다. In order to examine the degree of heavy metal pollutions around Samcheonpo and Youngkwang power plants, marine sediment samples were analyzed to determine heavy metal contents. Some of these sediment samples were also analyzed by using of a sequential extraction technique to know geochemical forms of the metals. The results showed that the spatial distribution of heavy metals coincided very well with those of mean grain size, carbonates and organic matters. The chemical speciation data using sequential extraction analysis also showed that a considerable amount of heavy metals except for Mn were bounded in the residual fraction, which mode of occurrence of heavy metals was generally interpreted as being the result of the lithogenic origin.

An environmental geochemical survey of heavy metal distribution in marine surface sediments around the ocean of Samcheonpo coal-fired power plant was conducted to investigate the possibility of coal-ash leakage from ash pond and the associated heavy metal pollution in sedimental deposits due to the operation of the coal-fired power plant. The X-Ray Diffractometry (XRD) analysis showed that the main leakage point of coal-ash was limited to a single site of the first ash pond. It also appeared that the amounts of organic carbon and metal elements were positively correlated to the grain size distribution, and that Co, Cr, Cu, Fe, Ni, and Zn were bounded to organic ligands. However, the distributions of Cd, Hg, and Mn did not have any significant correlation with the sediment grain size and organic matters. In particular, the distribution of Cd appeared to be affected by the concentration of the carbonate materials in the study area.
