| 英文摘要 | This study investigated the organic carbon, reduced inorganic sulfur, and heavy metal distribution in superficial sediments at an estuary, a wastewater discharge area, and a mariculture area, as compared with an unpolluted distal site, in the north Yellow Sea, China. Sediment grain size, acid volatile sulfur (AVS), chromium (II)-reducible sulfur, elemental sulfur, total sulfur, total organic carbon (TOC), total nitrogen and trace metal content were determined for each site. These results indicate that pollution leads to increased TOC at all affected sites, which in turn leads to elevated AVS. The resultant change in diagenetic environment leads to changes in the mineralogical fate of Mn. Pb, Zn, Cu, and Cd: all are present at elevated concentrations, and with more metal in the non-residual fractions. Cd shows by far the most elevated concentrations and most significant increase in non-residual fractions and consequently poses the most significant pollution risk.; This study investigated the organic carbon, reduced inorganic sulfur, and heavy metal distribution in superficial sediments at an estuary, a wastewater discharge area, and a mariculture area, as compared with an unpolluted distal site, in the north Yellow Sea, China.
