Dissolved Oxygen - Environmental Measurement Systems

As oxygen in the atmosphere is about 20.3%, the partial pressure of oxygen at sea level (1 atm) is 0.203 atm. Thus the amount of dissolved oxygen at 100% saturation at sea level at 20° C is 9.03 mg/L ¹⁰. The equation shows that water will remain at 100% air saturation at equilibrium. However, there are several factors that can affect this.
