Heavy Metal Uptake Capacity Of Some Trees For Phytoremedial Application

The concentration of Pb, Mn, Ni, Cu and Cd were determined in leaf and bark sample of roadside trees (Tectona grandis, Shorea robusta, Azadirachta indica, Ficus religiosa, Saraca indica and Eucalyptus citriodora) as a means of assessing the potential of the trees to bioaccumulate heavy metal. The results concluded that the bioaccumulation of metals varied between the leaf and bark. The plant as indicator, accumulator and excluder depend on the concentration of metal present in different plant part with respect to their concentration in soil. All the studied tree species are accumulator, indicator and excluder for heavy metals and used in phytoremediation purpose especially with respect to Cu, Ni and Mn pollution in soil.
