A study was conducted to investigate heavy metal contents in dominant plant species and their associated soils in a Zinc-Lead mining area in Ganluo County of Sichuan Province. Contents of such heavy metals as Pb, Zn, Cd, Cr and Cu were determined in 13 plant species in order to assess their potentials in phytoremediation of heavy metal polluted areas. The study revealed that soils of the mining area were highly contaminated by Pb, Zn and Cd. The Pb concentration in the 13 plant species was over 10 times greater than that in other plant species, indicating their potentials in in-situ remediation of the heavy-metal contaminated soils. Among the studied plant species, both the highest transfer factor (TF) and the highest bioaccumulation factor (BF) of plant species 1 were greater than 1, and this species can be designated as hyperaccumulator. It can be used in phytoremediation of contaminated soil in mining areas. Pteris cretia Linn. var. nervossa (Thunb.) ching et S.H.Wu, Clinopodium gracile (Benth.) Matsum., Anemone tomentosa (Maxim.) Péi, Erianthus rufipilus (Steud.) Griseb, Conyza canadensis (L.) Cronq. and Solanum surattense Burm. can accumulate Zn. Cd concentrations in C. canadensis and Eupatorium adenophorum were 17~61 times higher than that in other plants. In addition, both TF and BF of E.adenophorum were over 1 for Cd and its absorption characteristic of Cd is worth further research.
