Fast growing industrialization has put a serious threat on environmental safety. Phytoremediation is emerging as a cutting edge area of research gaining commercial significance in the contemporary field of environmental science. Phytoremediation is the common, in situ, eco-friendly, cost effective, easily deployable, solar energy driven and aesthetically pleasing method for remediation of polluted soils, sediments, and wastewaters contaminated with single or multiple pollutants. Factory effluent toxicity was studied by analytical method (hydro-chemical variables), by phytosociological method (community structure) and by assessment of toxicity on Cicer arietinum. The diurnal variation in dissolved oxygen concentration in aquatic ecosystem was also studied. The study fairly demonstrates the role of Lemna minor and Sphagnum squarrosum mosaic as efficient and viable phytoremediator tool as a cleanup option for surface water contamination.
