Abstract
Heavy metals contamination is a major environmental problem which requires immediate human attention. The use of plant species to remove pollutants from soils, generally defined as phytoextraction. In order to evaluate phytoextraction of contaminated soils, a pot experiment conducted using two plants Barley, Canola three kinds of heavy metals (Cd, Pb, Ni) with 3 levels in a completely randomized factorial design with three replications. A reverse relationship was found between heavy metal concentration in treatments and biomass production of selected plants. Uptake Index showed that Canola had a better potential for Cadmium, Lead and Nickel phytoextraction.
