042881 ARA N, JAMIL S (Botany Dep, L.N.M Univ, Darbhanga, Bihar) : Analysis of selected physico-chemical parameters of two ponds of madhubani. Indian J Sci Res 2020, 10(2), 85-91.
Present study was aimed to observe the monthly variations in selected physico-chemical parameters of surface water of two perennial ponds of Madhubani district of Bihar state. Selected parameters were determined for one year that is from January to December in 2018. The maximum value of water pH, temperature, turbidity, alkalinity, transparency, total dissolved solids, dissolved oxygen, free carbon dioxide, Biological Oxygen Demand, Chemical Oxygen Demand, Chloride contents Nitrates and Calcium and Total hardness of the pond situated near R.K. College, Madhubani were found as 8:5, 350 c, 48.0, 158.74, 150.0cm, 1270 mg/l, 852 mg/l, 7.38 mg/l, 42.28, 58.74, 29.62 mg/l, 8.34 mg/l, 48.64 mg/l, 151.60 mg/l respectively, while the maximum values of same parameters of an abandoned pond were, 8.3, 360 c, 46.0, 155.18, 142 cm, 1228 mg/l, 8.62 mg/l, 7.46 mg/l, 42.78, 59.58, 31.24 mg/l, 9.52 mg/l, 49.85 mg/l, and 146.62 mg/l. Present study indicates the existing health of these two perennial water bodies being used by the local people. Based on the above data suitable measures may be taken by the administrators to reduce the different loads of pollutant to maintain the purity of these perennial resource of water bodies.
