impact of hindon river water on selected riparian flora (azadirachta indica and acacia nilotica) with special reference to heavy metals

The present study aims to identify the impact of polluted aquatic body i.e. river hindon on two selected riparian flora i.e. azadirachta indica and acacia nilotica. during the course of study the average concentration of different metals in river water was found as iron (fe) 11.27ppm±3.50, manganese (mn) 4.00ppm±1.26, cadmium (cd) 0.08ppm±0.07, nickel (ni) 0.63ppm±0.17 and zinc (zn) 1.46ppm±0.38 respectively. the average concentration of heavy metals in a. indica of sampling site was found as iron (fe) 24.76ppm±6.25, manganese (mn) 5.04ppm±1.38, cadmium (cd) 0.05ppm±0.05, nickel (ni) 0.34ppm±0.20 and zinc (zn) 53.92ppm±19.29 respectively while in control site plant average concentration was found as iron (fe) 17.18ppm±3.96, manganese (mn) 3.63ppm±1.63, cadmium (cd) 0.02ppm±0.03, nickel (ni) 0.16ppm±0.06 and zinc (zn) 31.26ppm±12.11 respectively and average concentration in a. nilotica of sampling sites was found as iron (fe) 45.78ppm±10.67, manganese (mn) 42.08ppm±11.98, cadmium (cd) 0.59ppm±0.51, nickel (ni) 40.83ppm±12.16 and zinc (zn) 144.10ppm±49.94 respectively while average concentration in control site plant was found as iron (fe) 27.76ppm±9.49, manganese (mn) 22.75ppm±7.09, cadmium (cd) 0.42ppm±0.27, nickel (ni) 23.53ppm±8.02 and zinc (zn) 96.61ppm±24.78 respectively. one way anova shows statistically significant difference between sampling site plant and control site plant for all the studied metals except cr in a. nilotica f (3, 42) = 0.589, p= 0.626. a big difference was found in the concentration of metals between sampling site plants and control site plant. in case of metal uptake a. nilotica was found more efficient as comparison to a. indica.
