Abstract

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.

Key words: moss, heavy metals, steel mill, pollution index
