Increasing urbanization, industrialization and over population is one of the leading causes of environmental degradation and pollution. Heavy metals (HMs) such as Pb, Zn, Cd, As etc. are one of the most toxic pollutants which show hazardous effects on all living creatures. Lead is one such pollutant which disrupts the food chain and is lethal even at low concentrations. The aim of phytoremediation research is to identify metal-tolerant plants that are capable of uptake and efficient translocation of HMs to harvestable above-ground organs. The main objective of this study was to assess the metal tolerance of Eleusine coracana (Ragi) and Pennisetum glaucum (Bajra) after exposure to lead (Pb) solutions. Plants were grown hydroponically using coconut coir and were exposed to different concentrations of Pb (300 ppm, 400 ppm, 500 ppm, 700 ppm and 1000 ppm). Various physio-biochemical parameters were studied. Determination of heavy metal in the residual water from coir and from plant samples was done using the spectrophotometer. The concentration of Pb in Eleusine coracana was found to be much higher compared to Pennisetum glaucum. The results of this research showed that Ragi and Bajra of the family Poaceae are hyper accumulator plants that can concentrate heavy metals in their different parts, thus they can be used for remediation of polluted area. This report shows the ability of these plants to accumulate Pb. The benefit of this technology is the potential for low cost remediation.
