Five species of herbaceous plants such as Xanthium sibiricum, Lagopsis supina, Taraxacum mongolicum, Chenopodium glaucum and Poa annua were used to study the uptake, bioaccumulation and translocation of soil heavy metal lead (Pb) and to explore the restoration capacity of plant to soil severely polluted by Pb near the western hills of Linfen City. The results showed that the biomass accumulation of Poa annua was the highest among the tested plants under Pb treatment; the contents of Pb in above-ground biomass of all plants were greater than 1 000 mg/kg in 10 000 mg treatment group, particularly in Lagopsis supina, it illustrated the highest content and reached to 5 447.25 mg/kg. In the under-ground biomass, the similar trend as the above-ground biomass was observed, and the contents also reached up to 1 000 mg/kg in 10 000 mg treatment group, the maximum content was 13 448.5 mg/kg in the Xanthium sibiricum. The biological concentration factor and translocation factor of Lagopsis supine were all the highest, therefore, the results suggested that the Lagopsis supina was the Pb hyperaccumulation plant, and the other four kinds of plants have strong ability of Pb uptake, and they all can be used to remedy soil polluted by heavy metal.
