ABSTRACT

This paper reports that the heavy metal accumulation in marine seaweeds. Algal samples collected from Korean coast were analyzed to determine the concentrations of Cu, Cd, Cr, Zn and Pb. In general, heavy metals were found to be concentrated in many kinds of Korean seaweeds. The concentration levels of accumulated heavy metals in the marine seaweeds was in the following order: Zn>Cu>Cr>P{b>Cd. The concentrations of the heavy metals in the seawater were the highest in lyajin harbor. Sargassum horneri, a brown alga accumulated high concentrations of Cu (80.66㎍ㆍg-1 dw) and Cr (31.54 ㎍ㆍg-1 dw). The high concentraitons of heavy metals were accumulated in the brown algae.

Key words: accumulation, East Cost, heavy metal, seaweeds
