Abstract: The research was carried out to estimate the potential of Hydrilla verticillata in phytoremediation which can be an innovative approach to check the increased heavy metals pollution in aquatic ecosystem. The present study also emphasized on the ability of different parts, stem, root and leaves of fresh Hydrilla plant in terms of tolerance & degradation of lead pollution in water bodies. The plants were treated to 3 different lead (Pb) concentration of 10, 20 & 30 ppm for 15 days. Heavy metal analysis was done with atomic absorption spectroscopy. Significant differences were found in
removing capacity by plant for Pb in all concentrations of 10, 20 and 30 ppm during experiment period. The highest removal ratio for Pb was 7.98 ppm, in the roots 6.67 ppm in leaf and lower removal was 5.28 ppm in stem at concentration of 30 ppm for 15 days. There was accumulation in the root more than the stem & leaf. It was root> leaf> stem> respectively.
Keywords: Phytoremediation; Hydrilla verticillata; Accumulation, Atomic spectrophotometer.
