Abstract

In the present study phytoextction of Pb from soil by macrophytes was performed. Two emergent macrophytes Alternanthera philoxeroides and Hygrophila shoolis removed amount Pb during 2 months experiment. Dry biomass of plant and concentration of Pb were measured at different portions of plants. Dry biomass of plants decreased with increase of Pb concentration in soil which Alternanthera philoxeroides was more affected. Root accumulated higher metal concentrations for the macrophytes than shoots thus Transfer Factor (root: stem and leaves) clearly revealed that low transportation of Pb from root to stem and leaves however in low concentration of Pb in soil Alternanthera philoxeroides shows higher transportation. The results indicate that Hygrophila shoolis showed much greater tolerance and extraction to metal though the uptake was low, as a result Hygrophila shoolis can be more efficient for Pb phytoremediation but could not be useful in soil treatments for removal of Pb.
