Green Revolution-Removal of Lead from Battery Industrial Effluent by Phytoremediation using Eichhornia Crassipes

Lead (Pb) being very high poisonous heavy metal, non-biodegradable affects the food chain and are hazardous to all living beings. This paper investigates about the removal of lead from lead- acid battery effluent by phytoremediation technique using Eichhornia Crassipes (Water Hyacinth). Synthetic Chelator (EDTA) is induced to increase the mobility and uptake of lead by the plant from the effluent. Removal of lead from the contaminated effluent is varied by concentrations of 5 ppm, 10 ppm, 15 ppm and it is tested with the time interval of 15 days. The parameters like concentration of lead in the effluent, concentration of root and shoot uptake by the plant, degradation of lead by the plant, proline, chlorophyll, carotenoid characteristics of the plant is considered. The factors such as Bioconcentration Factor (BCF), Metal accumulation in plant and water, Enrichment Factor (EF), and Translocation Ability (TA) are calculated. The uptake of lead by the plant has been transferred from root to various other parts of the plant. Accumulation of lead in various parts of the plant, soil and water sample is analyzed by using Atomic Absorption Spectroscopy.
