Abstract: An engineering based remediation technologies of heavy metals from contaminated soil are time consuming, expensive, create noise to the environment. Accumulation of heavy metals such as Pb, Cd, Hg, Cr, Ni is destructive to not only plants and animals but also to complete ecosystem. Lead contamination keeps on increasing day by day from industrial waste, paints, ceramics, use of biosolids and many more. Metals cannot easily degrade so effective remediations need to be required to reduce the toxicity. Phytoremediation is most promising approach to degrade the contamination, this is environmental friendly approach, cost effective, socially accepted, easy to maintain and it also has long term applicability. It involves the growing hyperaccumulator plant species to detoxify and remove environmental contamination by biological, chemical, physical processes of plants. Hyperaccumulators are plant species that achieve shoot to root metal concentration ratio greater than one. Brassica juncea and Vetiveria zizanioides grass are well known Pb hyperaccumulator. This review article describes the Lead contamination, effects of Lead toxicity in plants, phytoremediation of lead using Brassica juncea and vetiveria zizanioides, effects of Reactive Oxygen Species (ROS) in phytoremediation and chelate assisted phytoremediation.
Keywords: Phytoremediation, Hyperaccumulator plant species, environment friendly, ROS, Chelate assisted phytoremediation.
