An Investigation into Chemical Parameters of Water of Dhaleswari - A River alongside Tannery Village of Bangladesh

This investigation attempts to assess the chemical parameter of water of Dhaleshwari river Savar, Dhaka alongside the newly constructed tannery village of Bangladesh. The chemical parameters like pH, Electrical Conductivity (EC), Dissolve Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Salinity are determined. The result reveals that the pH of water collected at different points and at different times of year were ranges from 7.60 to 6.50. EC of water collected at different points and at different times of year were ranges from11.80 µS/cm to 2080 µS/cm. The average value of DO at spot-1 was 4.79166±3.23 mg/l. Spot-2 showed average DO about 6.571667±1.47 mg/l. Biological Oxygen Demand (BOD) of water collected at different points and at different times of year ranges from 1.13 to 17.1 mg/l. Throughout the study period the monthly value of COD were within the range of 218.12mg/L (as minimum value) to 1276.6 mg/L (maximum value). In the study area Salinity of water collected at different points and at different times of year ranged from 0 (minimum) to 0.1 (maximum).Read Complete Article at ijSciences: V82019052073 AND DOI: http://dx.doi.org/10.18483/ijSci.207
