This study evaluated lead (Pb) and zinc (Zn) accumulation in Carex gentilis Franch. grown in nutrient solution in order to assess its phytoremediation ability to remove the contaminations from soil and water. C. gentilis plants were grown in pots containing a nutrient solution amended with increasing doses of Pb (0, 200, 400, 600 and 800 mg/L) and Zn (0, 50, 125 and 250 mg/L) in a completely randomized design with three replications. The results showed that C. gentilis showed a significant characteristic of Pb accumulation, and its highest accumulation of Pb in shoots (Pb for 600 mg/L and Zn for 125 mg/L, respectively) reached 1834.17mg/kg, while its bio-concentration factor was 3.1 and the transfer coefficient was 1.3, and it also found that Zn could enhance the shoots bio-concentration capacity of Pb. The results demonstrated highly that C. gentilis was a plant of Zn accumulator and Pb hyperaccumulator, which provided a new material to study the mechanisms of Pb bio-concentration, transport, tolerance and phytoremediation for soil contaminated with Pb.
