Abstract  

In order to reveal the pollution state of sediment in dump site,we determined the acid volatile sulfides (AVS)and simultaneously extracted metals(SEM)of surface sediment collected from the marine dump site of Cangnan,and the AVS,SEM,ΣSEM-AVS and their distributions were also analyzed.The result showed that the AVS in the surface sediment of dump site was between 0.19-1.88μmol·g-1,and the AVS in sediment near dump site was higher than the circumjacent areas.The mean value of SEM was 2.4μmol·g-1,and the contents of SEM were increased toward to dump site.At the mention of the contribution to ΣSEM from single heavy metal,the order was Zn > Cr > Cu > Pb > Cd,and the contribution of zinc basically was higher up to 50%,while the cadmium was less than 1%;therefore,the distribution was mainly controlled by zinc.The rations were larger than zero of ΣSEM-AVS;furthermore,ΣSEM-AVS in the dump site and nearby area was higher than the seacoast stations.The metals(SEM) in the surface sediment of dump site posed toxicity to the organisms,thus,there could be potential heavy metals ecological risk in the dump site.
