Effects of Heavy Metals (Copper, Lead, Zinc) Stress on Absorption and Accumulation Characteristics of Sedum aizoon L.

Abstract:

By using artificial water culture, transportation and accumulation of Sedum aizoon L. under heavy metals (copper, lead, zinc) stress were studied .The result showed that aizoon had a certain ability of accumulating heavy metals. When Cu2+ concentration was more than 40umol/L, the enrichment of copper ability had reached to the level of hyperaccumulation plants did. Besides, when Pb2+ concentration was more than 60umol/L, the aboveground part saturated; while when Pb2+ concentration was about 730 mg/kg, the underground part Pb2+ enrichment was increasing to the extent of Pb2+ concentration was 9600-16000 mg/kg. It will provide a new kind of material for phytoremediation applied in polluted environment.
