摘要：Water samples from 25 different stations along the Neeru stream and its tributaries / sub-tributaries has been collected and analysed for anions viz., Fluoride, Chloride, Nitrate, Phosphate and Sulphate for two years (Jan 2014- Dec 2015) by using Ion chromatography with 3.2 mM sodium carbonate and 1 mM sodium bicarbonate as mobile phase and 50 mM solution of sulphuric acid as suppressor. The observed values of Fluoride, Chloride, Nitrate, Phosphate and Sulphate were found to be in the range of BDL - 0.85, 0.11 - 9.88, 0.02 - 7.78, BDL - 0.39 and 0.26 - 9.56, respectively. Possible reasons for the fluctuations of these anions in the Neeru stream have also been discussed. All analysed anions have been found within WHO and BIS permissible limits.
