Abstract:

The upper stream of Huangpu River is the main surface drinking water sources of Shanghai.The quality of the water in this area has a direct impact on the residents' daily life and healthy security.There are nearly 17 million residents living in Shanghai now.The surface water,surface sediment and the surface soil surrounding from the upper stream of Huangpu River were collected.The content of the Pb,Cd in the surface water,surface sediment and the surface soil surrounding were analyzed.The results show that in the main current of Huangpu River,the average content 〖JP2〗of lead is 3234 μg/L and the cadmium is 022 μg/L.〖JP〗In the branch water,the average content of lead is 086 μg/L,the cadmium is 013 μg/L.In the surface sediment of the branch,the average content of lead is 327 μg/g,but is 218 μg/g in the main stream.In the surface soil surrounding,the content of the lead is between 2022 to 3903 μg/g.In the surface sediment,the average content of the cadmium is 03 μg/g.In the surface soil surrounding,the content of the cadmium is basically in 015 μg/g.In this article,the anthors judged the main home medium of lead,cadmium in drinking water sources of Huangpu River by analyzing the accumulate characteristics.According to the conclusions of this article,the lead,cadmium concentrate mostly in the surface sediments of this region.Lead pollution is mainly affected by the surrounding soil.Some low concentration of heavy metal cadmium have been input in the regions of sampling points 2 (intersection point of Xie tang and Yuan xiejing) and 4 (intersection point of  Shu liaojing and Heng liaojing) in a shortterm.In the end of this article,some scientific suggestions for the protection of drinking water source of Huangpu River,Shanghai were put forward.
