| Abstract: | A field survey on the content of heavy metals in soils and plants in lead-zinc mining area of Duyun Niujiaotang was carried out,and the absorption and accumulation characteristics of heavy metals between plants and soil were compared.Results showed that the soils and plants in the mining area were highly contaminated by Cd and Pb.Among 9 species of the collected herbaceous plants,the contents of Pb,Cd in the stem and leaf of Ficus tikoua Bur are the highest,with BCF 1.32 and 0.96 separately,and translation ... |
