Abstract: Considering the serious pollution of lead (Pb) in soil, it is urgent to effectively select Pb-tolerant plant species. Pot experiments were conducted to investigate the remediation efficiency of Brassica juncea and Vetiveria zizanioides L. for Pb-contaminated soil through phytoextraction and phytostabilization, with Pb concentrations of 400, 800, 1200, 1600 and 2000 mg/kg respectively and the experiment cycle as 30 d. The tolerability, accumulation and immobilization capacity of these two plants for Pb were compared. The results showed: (1) Pb was mainly accumulated in the roots, and the accumulation capacity of V.zizanioides L. was higher than that of B.juncea, with the concentrations of B.juncea and V.zizanioides L. reaching 206.62-902.40 mg/kg and 288.42-1102.47 mg/kg in roots respectively, and accumulation amounts as 70.75-138.31 μg/plant and 99.09-220.49 μg/plant respectively. This indicated that V.zizanioides L. displayed a better remediation efficiency than B.juncea. (2) The Pb removal rates of V.zizanioides L. and B.juncea decreased with the increase of Pb content in soil, while the immobilization rates increased with the increase of Pb content in soil. The maximum removal rates were as low as 1.02% and 1.78% respectively, and the immobilization rates reached 11.22% and 16.78% respectively. The remediation pathway of the two plants was identified as phytostabilization rather than phytoextraction. (3) The results of principal component analysis showed that proline played an important role in accumulating Pb. V.zizanioides L. could be used as an alternative plant for phytoremediation of Pb-contaminated soil.
