The present study analyses the potential capacity of aquatic macrophytes to accumulate heavy metals from contaminated waters of three different aquatic bodies namely Mahil Talab, Sumera Talab and Kothi Talab (lake). Four different macrophytes taken for study due to their abundance, are named as Eichhornia crassipes (Mart.), Hydrilla verticillata (L. F.), Chara spp. (L.) and Lemna minor (L.) Samples for the analysis of heavy metals were collected from these ponds during the period of October 2015 to September 2016. Five heavy metals named as Fe, Cd, Cu, Cr, Pb and Ni were analyzed in water, sediments and selected plant species which were abundant in water. The amount of metals and their accumulation status recorded in the studied macrophytes are arranged in the given sequence Fe>Pb>Cd>Cr>Cu>Ni. On the basis of metal concentration in different aquatic plants, water bodies and sediment, Pb and Cd was found to be target metal for the removal from the selected water bodies. The present experiments were carried out in the laboratory to analyze the Pb and Cd uptake capacity by above mentioned aquatic macrophytes. From the aspect of phytoremediation in present research, out of the four different macrophytes as above E. crassipes and Chara spp. may be considered as more affective for remediation of contaminated water bodies of Bundelkhand region especially for Pb and Cd removal.
