Monthly variation and interrelationship of physicochemical characteristics of a perennial pond at a biological park in Patna, Bihar, India

Abstract

The present study was designed to observe the monthly variation and interrelationship among the physicochemical characteristics of the surface water of a perennial pond situated at Biological park also known as Sanjay Gandhi Jaivik Udyan, Patna. The different physicochemical parameters was determined for the period of two years i.e from May, 2016 to April, 2018 to analyse the pond water quality. The maximum value of water temperature, transparency, total solids, total dissolved solids, total suspended solids, turbidity, pH, conductivity, dissolved oxygen, biological oxygen demand, chemical oxygen demand, total alkalinity, chloride, total hardness, calcium hardness, magnesium hardness, nitrate, inorganic phosphorus, sodium, potassium were found as 32.6 ± 0.24 °C; 24.57 ± 0.18 cm; 1510.66 ± 4.50 mg/l; 1210 ± 0.89 mg/l; 478.33 ± 2.11 mg/l; 37.46 ± 0.22 NTU; 8.54 ± 0.0245; 542 ± 11.57 µ S cm¯1; 8.216 ± 0.01 mg/l; 6.73 ± 0.074; 14.27 ± 0.114 mg/l, 269.36 ± 0.157 mg/l, 63.51 ± 0.13 mg/l, 333.33 ± 2.581 mg/l; 101.2 ± 0.089 mg/l; 19.13 ± 0.068 mg/l; 1.56 ± 0.004 mg/l; 1.43 ± 0.0078 mg/l; 7.726 ± 0.025 mg/l, 4.81 ± 0.215 mg/l respectively during the study period. This study therefore gives insight about the existing health of the pond and will be helpful to take suitable measure by the authorities to maintain the healthy environment and wholesomeness of the pond.
