초록

This study was carried out to investigate the contents of heavy metals with respect to the depth, particle size and Tessier et al. method in surface sediment of the Nakdong river. The contents of Cd, Cu & Pb were high or similar with increasing depth, but Mn & Zn were high to middle depth. Generally, the contents of heavy metals were found to be high as the particle size become more small and more deep. Because the more particle size was small, the specific surface area was large, the contents of heavy metals was high for increasing affinity. It was estimated that the types of heavy metals contained in surface sediment by Tessier et al. method was dissimilar with anaerobic condition, pH and degradation of organic matter, etc.
