摘要: 采集了钢铁厂周边的苔藓植物,分析了苔藓植物中6种重金属Cr、Ni、Cu、Zn、Cd和Pb的含量。结果表明,钢铁厂周边苔藓植物重金属含量大小表现为Cu>Cr>Zn>Pb>Ni>Cd,其平均值分别为788.836、311.851、124.773、117.519、58.406、2.842 μg/kg,Cu含量最大值为2 186.866 μg/kg,Cd元素含量最小值为0.027 μg/kg。通过相关分析和聚类分析得出,Cr、Ni、Zn、Cd和Pb 5种重金属可能来自同一污染源,Cu独自来源于某一种污染源。通过计算得出,钢铁厂周边苔藓植物的综合污染指数为362.17,污染负荷指数为79.33。

Abstract: The moss were collected around the steel plant, and analyzed the contents of 6 heavy metals elements Cr,Ni,Cu,Zn,Cd and Pb in moss. The results showed that the order of heavy metal content moss in the surrounding steel plant was Cu>Cr>Zn>Pb>Ni>Cd, the average was 788.836,311.851,124.773,117.519,58.406,2.842 μg/kg, respectively, the maximum content of Cu was 2 186.866 μg/kg, the minimum content of Cd was 0.027 μg/kg. Through the correlation analysis and cluster analysis in the steel plant, it was concluded that Cr,Ni,Zn,Cd,Pb in all the elements may be from the same pollution source, and the Cu element came from a single source of pollution. The comprehensive pollution index of moss was 362.17, and the pollution load index was 79.33.
