Abstract:
The present research has been carried out during rainy season, to estimate the changes in biochemical, anti-oxidative activity changes in E. crassipes along with the estimation of heavy metal content in water sample of waste water bodiespresent in trans-nearby regions of river Ganges/Yamuna in Allahabad city. The increasing oxidative stress levels caused due to heavy metal contents showed significant linear increase in antioxidant enzyme activities, i.e., catalase (CAT), peroxidase (PX), ascorbate peroxidase (AXP) and superoxide dismutase (SOD) of E. crassipes root and shoot growing in polluted water and along with the analysisof chlorophyll and protein content. Oxidative stress is essentially a regulated process, the equilibrium between the oxidative and anti-oxidative capacities determine the fate of the plant. At higher pollution concentration chlorophyll and protein content of E. crassipesis slightly affected.Conclusively, the present study demonstrates that E. crassipes can tolerate higher oxidative stress andit can be used forbioremediation in polluted water. Therefore, E. crassipes is helpful in reducing the aquaticpollution andthe study provides a cost effective management to water pollution.
