Study on the Potential Remediation of Rape to Soils Contaminated by Cadmium and Lead

Abstract

Abstract:

Pot experiment was conducted to study the tolerance and accumulation indexes of rape under different Pb and Cd
concentration. Low level of cadmium, lead compound on rape biomass, nitrate reductase activity and some catalytic play an active role, while high levels showed a inhibitory effect. Absorption of cadmium, lead in rape is different . Transfer coefficient of cadmium in rape is higher than that of lead. It shows that rape can be use of cadmium well. Studies have shown that rape can grow in the soils contaminated by cadmium and lead, get a high biomass ,and have strong absorptive capacity of cadmium. So it can serve as a kind of plant with repairing cadmium, lead contaminated soil.

Key words: heavy metal, Cd , Pb, oilseed rape, phytoremediation
