Assessment of Heavy Metal Levels in Sediment of the Xiangjiang River Section Flowing through Changsha

Abstract:

In order to assess polluting condition of heavy metals in sediment of the Xiangjiang River Changsha section, the spatial distribution of four heavy metals were determined in river sediments at six sampling stations. Geo-accumulation Index of heavy metals in superficial sediment of the Xiangjiang River Changsha section was in the decreasing order of Cd>Zn>Pb>Cu. On the whole, the pollution level was moderate-high, and the order of four heavy metals pollution lever was noted in the sequence of Liuyang River entrance of Xiangjiang> Juzizhou Bridge >Houzishi Bridge> the Second Xiangjiang River Bridge > Xiangjiang Super Bridge > Xiangjiang Sanchaji Bridge. The Potential Ecological Risk Evaluation showed that heavy metals ecological risk in sediment of the Xiangjiang River Changsha section was very high, Cd was the primary contribution element, followed by Pb.
