Studies on Hyper accumulation of Copper, Zinc and Nickel using plant Chromolaena odorata from contaminated soil

Anthropogenic activities of human being have led to heavy metal contamination in soil especially on the banks of rivers. However, for this heavy metal removal, many plant species called as metal accumulators show amazing property of accumulating metal from soil and help in soil clean up. Chromolaena odorata is one of such plant which shows hyperaccumulator activity with Bioconcentration factor ranging from 1.42 to 7.8 at different sites for Cu & Zn metal, whereas for Ni metal tolerance is observed. (BCF-0.043 to 0.076). This plant’s potential is useful for technologies like phytoremediation and phytoextraction. It is greener method of soil filtration.
