An integrated greenhouse experiment was conducted to examine the level of Pb, Cd and Cu uptake into Brassica juncea. The chelators ethylene diamine tetraacetate (EDTA) and ethylene glycol tetraacetic acid (EGTA) were compared. A brief analysis of the role organic matter content plays in tying up Pb bioavailability was conducted. Contamination levels of Pb, Cd, and Cu in soil were investigated by nitric acid digestion and water extraction methods. Results showed that EGTA was most effective at enhancing uptake of Pb, Cd and Cu into shoots and roots (p=0.005302), (p=1.72E-08) and (p=4.14E-06). Organic matter had a significant difference in the bioavailability of Pb between soil type treatments (p=1.55E-06). Pb, Cd, and Cu amounts determined in soil varied significantly between nitric acid digestion and water extraction methods.
