- 摘要:
- 对徐州北郊农田土壤中Pb、Zn、Cu、Cr、Cd 5种重金属的含量及对土壤的污染情况进行了测定和评价分析。结果表明:徐州北郊农田土壤受到了污染,该区域内有固体残渣、煤矸石和粉煤灰等的常年堆放,经过雨水淋溶后,这些固废中的重金属元素会向周边土壤中迁移,致使污染土壤中Pb、Zn、Cu、Cr、Cd 5种重金属的含量均高于当地土壤背景值。采用地质累积指数Müller指数分析表明,Zn、Cr没有表现出污染;Pb、Cu污染强度不大,表现出轻度污染;而Cd则呈现出极强污染,污染程度顺序Cd>Pb>Cu>Zn>Cr。
- Abstract:
- The contents of elements Pb,Zn,Cu,Cr and Cd of heavy metals in the farmland soil in the Northern suburb of Xuzhou city were measured and studied.The results showed that the area had solid wastes,coal gangues and fly ash.The elements of heavy metals in the soil will transfer to the aroundings by raining.The concentrations of heavy metals was higher than the background level.According to the geo-accumulation index,the contamination degree from strong to weak in soil was:Cd>Pb>Cu>Zn>Cr,among which Zn,Cr expressed no pollution,Pb,Cu light pollution and Cd heavy pollution.
