We measured the concentrations of various geochemical parameters (grain size, ignition loss [IL], chemicaloxygen demand [COD], acid volatile sulfide [AVS], total organic carbon [TOC], total nitrogen [TN] and tracemetals [Fe, Cu, Cd, Pb, Cr, Mn, As, Zn, and Hg]) in surface sediments in order to evaluate the pollution levelof organic matter and trace metals in sediment around Ulsan Harbor. Although the mean grain sizes (Mz) werein the wide range of 1.9 to 8.7Ø, the surface sediments consist of mainly finer sediments such as sandy mudand mud. The high concentrations of IL, COD, Fe, Mn, and Cr were observed in the Ulsan outer port, whilethe high concentration of AVS, TOC, TN, and most of trace metals (Cu, Cd, Pb, Zn, Hg) were observed nearthe Jangsaengpo port. Based on the TOC/TN ratios, the organic matter in the sediments of the study regionis likely to originate from oceanic source such as body or fragments of dead plankton. The organic matterssuch as IL and COD showed a good positive correlation with Mz, while the correlation between trace metals(except Fe, Cr, and Zn) and Mz no displays, indicating that trace metal concentrations in sediment are notsolely dependent on the grain size of sediment. The overall evaluation results for organic matter and metalpollution using the sediment quality guidelines and geochemical assessment techniques (enrichment factor andgeoaccumulation index) suggest that the surface sediments in the study regions are not polluted by organic matterand trace metals (except As).
