摘 要: 通过现场采样及实验室分析测试,对潮州市工业区及郊区农田表土中重金属(Cd、Cr、Cu、Pb、Zn和Ni)的含量及分布进行了研究.结果表明,潮州市工业区土壤中Cd、Cr、Cu、Pb、Zn和Ni的含量均高于郊区农田土壤.以土壤环境质量标准(GB15618-1995)作为评价标准,计算出各工业区土壤的单因子污染指数和综合污染指数.结果显示,各工业区土壤均已受到不同程度的污染.分析结果认为,工业区土壤重金属的主要来源是企业"三废"的排放和汽车尾气的污染. The concentration and distribution character of Cd, Cr, Cu, Pb, Zn and Ni in industrial district of ChaoZhou City and suburb cropland was studied. The concentrations of Cd, Cr, Cu, Pb, Zn and Ni in industrial districts were higher than those in suburb cropland. According to the soil environmental quality standards (GB15618--1995),the status of soil pollution by heavy metals was evaluated by using single factor pollution index and integrated pollution index.The results showed that the soils in industrial area were polluted by Cd, Cr, Cu, Pb, Zn and Ni.The main sources of heavy metals in soils of industrial district were industrial pollutant discharge and vehicle emission.
