| 摘 要： | 分析了浙中某地2 300个表层土壤样品中8类重金属元素的含量,并与1987年区域化探数据比较,发现Cd、Hg、Pb、Cr、Ni、Cu、Zn等重金属出现了显著升高,升高的区域与工业区分布吻合。研究区内大约6.09%的土壤受重金属中—重程度的污染,40.26%的土壤达到轻污染,污染区的分布主要与交通干线和五金企业聚集区吻合,而与地质背景无关,表明研究区重金属污染主要来源于五金企业。

| Abstract: | Based on data of heavy metals concentrations of 2 300 topsoil samples collected in central Zhejiang Province and regional ge-ochemical exploration conducted in 1987, the authors analyzed the characteristics of Cd, Hg, Pb, Cr, Ni, Cu and Zn concentrations. The concentrations of these 8 heavy metals increase significantly in the industrial districts. Approximately 6.09% and 40.26% of the soil is respectively subjected to moderate to heavy and slight pollution of heavy metals. The distribution of contaminated districts is consist-ent with the traffic trunk and hardware enterprise areas, and has nothing to do with the geological background, which indicates that the heavy metals are derived from local hardware enterprises. |
