以玉林市一些典型工业区的土壤为研究对象,用岛津AA-6601F原子吸收分光光度计测定土壤中Pb 、Zn、Cu 三种重金属元素的全量和有效态含量,并对含量状况进行分析和评价.结果表明:这些工业区的土壤铅含量明显高于国家土壤背景值,按土壤环境质量评价的二级标准,已达轻度污染程度; Zn元素除了在工业品住宅小区附近菜地的污染等级达到轻度污染外,其余的采样点都未受到污染; Cu元素除了在师院东校区德兴造纸厂排水沟的污染等级达到轻度污染外,其他地方均是安全的.

Taking a typical soil of industrial area in yuilin city as an example, the content of soil heavy metal Pb、Zn、Cu were determinated by AA-6601F atomic absorption spectrophotometer. the analysis of soil heavy metals Pb 、Zn and Cu were discussed in this paper . The results showed that: the total contents of Pb are higher than national background value obviously and have re-ached the criterion of slight pollution according to the second standard of soil environment quality.The pollution level of Zn element have reached the slight pollution only at the residential community near the vegetable industrial ,the other places had not been contaminated. It is only at the East Campus Dexing paper that Cu element’ pollution level have reached the slight pollution, the other places are safe.
