Abstract
Heavy metal concentration of Fe, Zn, Cu, Cd and Pb were analysed from seaweeds (Ulva pertusa, Sargassum thunbergii, Caulacanthus okamurae), sediments and seawater at the two experimental sites of Daebul and Sabjin industrial complex in Mokpo coastal area with a control site (Heugsando). Highest values of heavy metals were found at two experimental sites influencing by various pollution sources such as industrial drains, sewage and harbours. In contrast, the lowest concentrations was observed at the control site without any pollution source. The concentration levels of accumulated heavy metals were in the following order: seaweeds > sediments > seawater. Similar spatial distribution patterns were observed at the seaweeds, sediments and seawater for the highest mean values of the different heavy metals. This result show that seaweeds could be used as a biomonitors of heavy metals at coastal region.
