| 摘 要： | 对堆积15、25年左右的铅锌矿渣堆周围10、20、50 m农田土壤中的重金属铅和铜的含量及其变化规律进行调查研究。结果表明,堆积时间越长的渣堆周围土壤中总铅的含量越高,而总铜的含量相对较低;距渣堆越近的土壤中重金属总量越高;在50 m内距渣堆越远的土壤中有效铜的含量随距离的增加而升高,有效铅的含量却相反,在距铅锌矿渣堆周围50~100 m甚至更远范围内的土壤都会受到重金属铅的污染。

| Abstract: | The content and the change rules of lead and copper were investigated in the soils around the lead-zinc tailing for 10,20,50 m distance,which was piled up about 15 to 20 years.The results showed that the longer accumulation of tailing was,the higher content of lead in the soils around the tailing was,while the lower content of copper was relatively.The closer to the tailing,the higher the content of heavy metals in the soils around the tailing was.In 50 m distance,there were negative correlation between effective lead and distance,but the effective lead and distance had positive correlation.The soils around the Lead-Zinc tailing about 50～100 m or even further was possibly polluted by the lead. |
