| Abstract: | The geochemical characteristics of heavy metals, organic carbon, oil, sulfide, nitrogen, and phosphorus in surface sediments of the Changjiang estuarine and its adjacent regions were reported in this paper. The distributions of heavy metals, organic carbon, oil, sulfide, nitrogen and phosphorus in surface sediments were very irregular, and the high values of Cu, Pb, Zn, Cd, Hg, As, OC, oils, TN, and TP appeared in the Changjiang estuarine and the northeast region of the Hangzhou Bay; but the high sulfides, which was similar to the distribution of hypoxia area, in the outside of the Changjiang estuarine, the near top coastal region of the Hangzhou Bay, and the southeast region of the Zhoushan islands. The main sources of heavy metals, organic carbon, oil, sulfide, nitrogen, and phosphorus in surface sediments of the Changjiang estuarine and its adjacent regions were the input of the Changjiang river and land pollution matter. The Changjiang river input could affect the whole sea region, and the land pollution matter input only had influence on the coastal region. The sediment quality of the Changjiang estuarine and its adjacent regions were suitable for the sediment assessment. |
| Keywords: | heavy metal distribution source surface sediment Changjiang estuarine and its adjacent region |
