摘要
本文选择提钒炼钢厂内部分土壤为研究对象,测定了重金属元素(镉、铜、铬、铅、锌)的含量,并与样品粒度大小的关系进行了探讨,结果表明金属(铜、铬、铅、锌、镉)的浓度最大值出现在粒径较小(100目或160目)的样品中,同时将测定结果与土壤环境质量标准比较,结果表明镉、锌存在污染,其余元素均未超标。
In this paper,the soils inside the Panzhihua Vanadium Extraction Steel Works were sampled as study objects.The contents of metals such as cadmium,copper,chrome,lead and zinc were determined and the correlation of every metal content and the soil particle size was discussed.The results showed that the maximum contents of copper,chrome,lead,zinc and cadmium appeared in soil samples with smaller particle size（100 meshes or 160 meshes）.Besides,the results were compared with soil environment quality standards.The results showed that there were pollutions of cadmium and zinc in soils,meanwhile the contents of rest elements were not higher than the standards.
