Abstract

The present study was carried out to estimate the concentration of heavy metals (Pb, Cd, Mn, Cu & Ni) in drinking water collected from different fields located in Mysuru, Karnataka. Atomic Absorption Spectrophotometer was used to determine the concentration of heavy metals. The purpose of study was to assess heavy metals in drinking water and determining human health associated water contamination by heavy metals. The result show that average heavy metals in drinking water sample in winter seasons followed a descending order Mn>Cu>Ni>Pb>Cd and summer seasons followed a descending order Mn>Cu>Ni>Pb>Cd. It was observed that heavy metals not exceeded the maximum permissible limits in drinking water as specified by regulatory bodies except cadmium which was below standard and pollution index result confirmed significant pollution of Manganese and copper.
