摘要： Phytoremediation can play an important role in remediating the lead (Pb)-contaminated soils. Thus, capability of the plant species to absorb and transport Pb from root to the shoot is vital for successful phytoremediation. This study focuses on exploring the potential of Houttuynia cordata to treat Pb in soil. The results indicate that H. cordata could tolerate a high concentration of Pb (up to 1000 mg kg(-1)) and the main part of Pb accumulation is plant root. Furthermore, the inoculation of common soil bacteria Bacillus subtilis wb600 can facilitate Pb absorption by both root and shoot of H. cordata. The inoculation of Bacillus improves the transportation of Pb from the root to the shoot, suggesting that the combination of H. cordata and Bacillus might be used for treating Pb in the future.
