Abstract: The oxygen present in the water is of great importance for the maintenance of water balance, considering that it is a supply for microorganisms to reestablish the initial conditions after a disturbance caused by contamination from effluent discharges. Dissolved oxygen comes from photosynthetic activity, carried out by plants and algae, and through the water-air interface. Dissolved oxygen concentration is directly related to water temperature, salt concentration and atmospheric pressure. Temperature is an element that has a great interference in the means of supplying dissolved oxygen, photosynthetic activity and water-air interface. Therefore, the purpose of this article is to carry out a literature review aimed at describing the behavior of oxygen in terms of its sources of production and consumption, in addition to highlighting its relevance in the self-debugging process. Through this review, it was possible to show that dissolved oxygen is a fundamental element for the maintenance of water quality, considering its representativeness throughout the self-purification process. In addition, it was possible to verify that it is of great importance to consider the seasonal influences and climatic conditions of the regions where self-purification studies are submitted, considering the interference of elements and meteorological factors in the concentration of the element in the aquatic environment.
