Distribution and Pollution Assessment of Heavy Metals in Surface Sediments of Intertidal Wetland of Globally Important Shorebird Stopover Sites in Southern Jiangsu Province, China
摘要
Abstract
Total of 36 surface sediment samples were collected from 18 sampling sites of intertidal zone,and the distribution,contamination and source of heavy metals in the globally important shorebirds stopover sites of south Jiangsu were investigated.The results showed that the average content of heavy metals were Zn＞Pb＞As＞Cu＞Cr＞Cd＞Hg both in spring and autumn,and there were no significant differences in the contents of heavy metals,except for As and Hg in different season,Cu and Zn in different intertidal zones,and Cd in different transects.The geoaccumulation index assessment indicated that the pollution status was Cd＞Pb＞As＞Cu＞Zn＞Cr＞Hg in spring,and Cd＞As＞Pb＞Cu＞Zn＞Hg＞Cr in autum.The potential ecological risk index indicated that As,Pb,Cu,Hg,Zn and Cr were all at the low ecological risk level,and Cd was at slightly high level.The principal component analysis indicated that the heavy metals mainly came from industrial emissions of the Rudong Economic Development Zone,motor vehicle exhaust and the ship pollution emissions of the local fishing ports.关键词
