Abstract
- This paper analyzes heavy metal content in the soil of abandoned tailings and dominant plants, and absorption and bioconcentration capability as well as cumulative characteristics of the four kinds of dominant plants such as Phragmites australis, Typha angustifolia, Miscanthus sinensis, Equisetum fluviatile for heavy metals Pb, Zn, Sb, Cu, Cr, Cd, As and Mn through investigating samples of the zinc antimony ore abandoned tailings. The results manifest that investigated eight heavy metals contents in the abandoned tailings all exceed soil background values of both Guangxi and the whole nation. Abandoned tailings soil is polluted most seriously by Mn, Sb and Cd, followed by As, zinc and Pb.
