Screening of Plants for Phytoremediation of Lead (Pb) on soils contaminated with Fly Ash

Traces of Heavy metal are found in fly ash. Fly ash generation is on the rise because requirement of power is on the rise in the developing countries going for industrial development. In the last few decades, newer methods of fly ash managements have been tried. Some of the innovations are technology dependent. These are rarely sustainable and are costly too. Phytoremediation has been tried with much success. This process is beneficial due to two major reasons. It is sustainable and cost effective. Backfilling and reclamation is a major way of disposal of fly ash. Phytoremediation of Lead (Pb) by locally available plants growing in Nagpur region (Maharashtra,India) is explored in this work. The observations suggests us to believe that that Vitex Negundo is the most efficient phytoextractor amongst the plants chosen. However, Cymbopogon Citratus displayed a steady increase in absorption over the entire year of experimentation. Cymbopogon citratus is found abundantly in Nagpur region and requires very little attention and care. Thus, this specie could be used for further studies with microbial inoculations and amendments for hyperaccumulation.
