Potability Studies Of Drinking Water In Villages Of Aundha, Hingoli District, Maharashtra, India

摘要

Iron is an essential trace metal, required as a constituent of oxygen carrying and oxidative-reductive micro-molecules such as haemoglobin, myoglobin and cytochrome. Amongst various components, iron is an important trace metal required for all biological systems. Owing to the universal presence of fluoride in earth's crust, all waters contain fluoride in varying concentrations. Fluoride is an element of high biological activity and has a tendency to accumulate in organisms, making detrimental effects in very low and high levels of exposure. Inorganic nitrogen may exist in the free state as nitrogen gas, or as nitrate, nitrite or ammonia. Nitrate represents the highest oxidized form of nitrogen. Many groundwaters have significant quantities of nitrates due to leaching of nitrate with the percolating water. Iron, fluoride and nitrate concentration along with temperature and colour, in the drinking water from some villages of Aundha taluka of Hingoli District were studied monthly during January to June 2005. The samples were analysed with standard methods and observed results were compared with prescribed limits set by WHO and ICMR.
