Paper Title:
Effects of Natural Organic Acids on Growth of Maize and Uptake of Copper and Lead by Maize in Contaminated Soil
  Abstract

Seven kinds of natural organic acids were added to moderate artificial contaminated soil to investigate the effects of natural organic acids on growth of maize seedlings and phytoextraction of copper and lead by maize. The results show that the effects of organic acids on plant growth are different in Cu and Pb contaminated soil. The natural organic acids can change the dry matter distribution of the shoot and the root, oxalic acid and tartaric acid can increase the root biomass in different degrees. Oxalic acid and tartaric acid can significantly increase the concentrations and uptake of Cu and Pb in the shoots of maize, indicate that oxalic acid and tartaric acid are potential phytoextraction intensifiers in phytoremediation of Cu and Pb contaminated soil.
