对黄河洽川湿地进行样品采集,采用国标法消化,测定了湿地土壤中Pb、Cd、Cr、Cu、Zn和Mn的含量,利用潜在生态危害指数法评价土壤重金属的潜在危害程度。结果表明该湿地属于很强生态危害,主要原因是Cd污染严重超标。
The soil samples were collected from Hechuan wetland and digested 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 was that the content of Cd Seriously exceed the standard.
