Abstract
The purpose of this study is to evaluate the concentrations of heavy metals in the marine sediments near the Masan bay and the Nakdong estuary, and to investigate the pollution intensity levels of six heavy metals using the existing pollution intensity assessment method. According to the US environmental protection agency, in the case of Cu, the B1 area was classified as severe pollution, while in Ni and Zn, it was classified as moderate pollution in some areas. According to the classification of Igeo, EF and PERF, the A and B regions were polluted by Cd. In particular, in the B1 region, Igeo, EF, and PERF values were the highest in all regions, and were regarded as serious pollution. According to the mean PEL quotient classification, which takes into account the effects of all six heavy metals, there is a 21% probability of toxicity from heavy metals in all regions. The highest concentration of Cd in the B1 region is 1.5 mg/kg. Therefore, the contamination of Cd contained in sediment near Masan Bay is serious, so it is necessary to clarify the cause and take careful approach to future treatment.
