Effects of EDTA, EDDS and Citric Acid on Growth of Maize and Uptake of Lead by Maize in Contaminated Soil

Abstract:

EDTA, EDDS and citric acid were added to moderate artiﬁcial contaminated soil to investigate the effects of the organic acids on growth of maize seedlings and phytoextraction of lead by maize. The results show that the effects of the organic acids on plant growth are different in Pb contaminated soil. The organic acids can change the dry matter distribution of the shoots and the roots and can increase the shoots biomass in most case. EDTA and EDDS can signiﬁcantly increase the concentrations and uptake of Pb in the shoots of maize, indicate that EDDS is a potential phytoextraction intensifier in phytoremediation of Pb-contaminated soil.
