Contamination of freshwater resources continues due to domestic effluents, industrial discharges and use of chemicals in agriculture. Sugar manufacturing industry produces a large amount of wastewater that contains different chemicals and various heavy metals. Heavy metals are toxic to human and also cause water and soil pollution. The objectives of this study were: to find a cost-effective phyto-remediation and biosorption method to reduce heavy metal contamination, i.e., Cd, Cr and Pb by evaluating the potential of Euphorbia Prostrata an indigenous plant species, in in situ and ex situ experiments.Euphorbia Prostrata were grown on different concentrations (100%, 50% and 0%) of wastewater in controlled conditions of 23 °C with 12 hr. dark and light cycle for 45 days and compared with underground extracted tap water collected from the same area, as control. Three harvests were taken after 15, 30 and 45 days of plant germination. Plants grown on wastewater show reduced growth on fresh and dry weight basis (80% and 50%), respectively as compared to plants grown on control. In phyto-remediation experiment, plants germinated on wastewater in field accumulated higher amount of heavy metals (20-55%) over a period of 45 days. Whereas, in biosorption experiment, biomass collected from plants germinated in lab adsorbed higher amount of heavy metals (>70%). The results suggest Euphorbia Prostrata as a promising plant for both phyto-remediation and biosorption of heavy metals.
