Evaluation of Physico-chemical Parameters of Manchar Lake Water and Their Comparison with Other Global Published Values

Abstract

The aim of current study was to evaluate the status of the Manchar lake water with respect to different physico-chemical parameters (electric conductivity, pH, chloride, phosphate, sulfate, total alkalinity, potassium, calcium, magnesium, manganese, iron, cadmium, copper, arsenic, nickel, zinc, chromium lead and selenium) in 2005-2007. Among the elemental investigation of Manchar Lake water except Co, Cr, Cu and Mn, other elements (Al, As, Ca, Cd, Fe, Mg, Na, K, Ni, Pb and Se) have higher values as compared to the permissible level of these elements in drinking water. The results were compared with WHO water quality guidelines as well as with literature values reported for global lake water.
