In this article,the Cd and Pb contents of soil were determined and their contaminations were studied in several miners tailings of Guangxi Debao.The results showed that the Cd and Pb contents in soil had all surpassed the background value of soil environment quality standard of Guangxi in concentration(Cd 0.08 mg·kg^-1 and Pb 20 mg·kg^-1).Moreover,the Cd content was obvious exceeding.Pb had no pollution according to the soil environment quality standard of China,but it had already achieved mild pollution according to the standard of GuangXi.The Cd content of soil in copper mine tailing arrived to 2.16 mg·kg^-1 and exceeded the tertius standard of our country and it had begun to affect the environment.The Pb content in lower reaches soil of the sulphurous iron ore tailing was 83.53 mg·kg^-1 and had no impact on the environment.The Cd content in soil increased significantly with pH increasing,while Pb content was decreased with pH increasing.The Cd content in soil arrived to serious pollution level as far as the environmental quality standards and individual pollution index were concerned.It should mitigate the harm to the ecological environment.There fore the correlated departments should emphasize the soil contamination by Cd and Pb in miners tailings,and adopt promptly some measures to control the pollution source and reduce the pollution degree.
