NELUMBO NUCIFERA (INDIAN LOTUS) COULD BE USED AS METAL HYPER ACCUMULATOR FROM AQUATIC BODIES OF BUNDELKHAND REGION OF UTTAR PRADESH, INDIAJAMSHED ZAIDI, RAJEEV NIRANJAN AND AMIT PAL
Aquatic plant based remediation innovation is increasing more consideration everywhere throughout the world especially in developing countries because of their metal removal efficiency and economic value. In the base of above citation the present study was conducted for assessment of metal accumulation ability of Nelumbo nucifera Gaertn. (Indian Lotus) for Lead (Pb) and Cadmium (Cd). To assess the accumulation ability of above mentioned metals of Nelumbo nucifera an experiment was set up in the laboratory. Firstly the plant was collected from the selected water body and washed clearly under tap water after that the plant samples were kept in Hoagland solution for three consecutive days and later on plant samples was dipped in the different heavy metal concentration tub such as 0.5 mg/L, 1 mg/L , 1.5 mg/L and 2mg/L and picked up at different time intervals, i.e. 24 hrs, 48hrs and 72 hrs. and then prepared for metal analysis. The result of metal accumulation in Nelumbo nucifera shows that in both metal it accumulated Pb (242 Î¼g/g) to maximum level in 2mg/L dose at 72 hrs and accumulated Cd ( 1.01 ) to minimum in 0.5 mg/L dose at 24 hrs. The present study showed that N. nucifera could be used for removing metals especially Pb from aquatic bodies which are contaminated by heavy metals.
