| Abstract: | The sediment samples were collected from Hechuan Wetland and Fenglingdu by the national standard method.The contents of Pb, Cd, Cr, Cu, Zn and Mn were detected and the potential ecological risk was estimated by the the potential ecological risk index.The result shows the wetland was seriously ecological hazarded.The main cause is that the content of Cd Seriously ex-ceeds the standard. |
