Determination of the level of some heavy metals from medchal lake in Telangana

The aim of this study is to review the research work on concentration   of heavy metals in drinking water sources of Medchal Lake. Industrial effluents discharged into the environment, aquatic ecosystem pose a serious threat to our agricultural Products and health. In view of this, levels of some of the heavy metals in Medchal Lake were determined by Atomic Absorption Spectrophotometry. The results obtained show that the mean values of all heavy metals (with the exception of Zn) in water samples from the polluted areas studied were significantly higher than in the control sites, Zn, Pb, Cr, Cu, Ni, Co, Ag, Fe and Mn were determined in water samples collected from Medchal lake. The results for heavy metals analyzed indicated that they are below the limit of admissible concentrations. Although low level of heavy metals was discovered in the lake water and they are within the permissible limits.
