Phytoremediation of heavy metal using L. leucocephala

Generally the percentage reduction of metals in all the treatments increased during the second harvest. The highest percentage reduction of As were 27.84% and 41.32% which were seen in T5 for the first and second harvests respectively. This could be as a result of the PKC alone which was mixed with the tailings during the treatment preparation even though it did not help in increasing the biomass.
