WebDissolved oxygen (hereafter abbreviated as DO) is oxygen (O 2) dissolved in water, and in the world of nature, it is dissolved in water in proportion to the partial pressure of O 2 in the atmosphere. Dissolved oxygen levels are expressed as the amount of O 2 dissolved per unit volume of water (mg/L). It is known that the saturation level of O 2 dissolved in … WebOriginally, the measurement of dissolved oxygen was performed by heating samples to drive out the dissolved gases and by analyzing the collected gas for oxygen by standard gas analysis techniques [6, pp. 388-389; 7, p. 411]. To eliminate this time consuming and cumbersome process, the Winkler technique was developed. The WebDissolved Oxygen – Most aquatic organisms need oxygen to survive. Dissolved oxygen is the oxygen present in water available to aquatic organisms. It is not the oxygen that is part of the water molecule but rather oxygen gas. Oxygen enters the water from the air through rain, turbulence and wind, and through the photosynthesis of aquatic plants. chittenden county fish game
