Analysis of dissolved oxygen of the tributaries of River Kosi in Madhepura region

Khushbu Kumari, Dinesh Yadav & Arun Kumar


Dissolved Oxygen (D.O) is the major means of respiration for all aquatic aerobic flora and fauna. It is the amount of oxygen absorbed at the water surface. Decrease in the dissolved oxygen levels can be lethal to aquatic organisms. The rate of dissolved oxygen depends on a variety of climatic conditions like temperature, wind speed, humidity etc. A range of D.O. fluctuations exists owing to the seasonal changes. In this study, analysis of dissolved oxygen was done, Wrinkler's method was used to calculate the amount of dissolved oxygen.
