| 摘 要： | Introduction Hailing Bay located in western Guangdong province is an important marine aquaculture base and a famous scenic spot. Moyang River which flows across Yangjiang is the major runoff and polluted source in the sea area of Hailing Bay. Hailing Bank ( approximately 5 000 m ) which was built to connect Hailing Island and the continent in 1964 has blocked the natural circulation of suspended sand and pollutants in seawater. Water flux through the Yangjiang harbor extensively decreases …

| Abstract: | The geochemical properties of sediment in the nearby seawater areas of Hailing Bay of the western Guangdong province were first time investigated in the dry period of 2001 and the flood period of 2002, respectively. The temporal and spatial characteristics of Cu, Pb, Zn, Cd and Hg concentrations, organic carbon and total sulfides contents, and granulometric distribution in the surface sediment from the Hailing Bay were analyzed. Results demonstrated that there were no remarkable changes in the composition of sediment between the dry period and the flood period;the average concentrations of Cu, Pb, Zn, Cd and Hg were 32.1 ± 17.5, 36.1 ± 10.0,respectively; surface sediments were dominated by clayey silt and sand, and their mean grain size was 4.62 ± 2.36 φ and in the range 0.52-7.55 φ; there existed obvious correlation between the concentrations of Cu, Pb, Zn and Hg, and among Cu, Pb, Zn and Hg concentrations, organic carbon contents and grain size of sediments. |
