What is dissolved oxygen?
Dissolved oxygen alludes to the level of free oxygen not bonded to any existing molecule in the water or other liquid substances. It is an important parameter in assessing water quality because of its influence on the organisms living within a body of water. In limnology (lakes studies), dissolved oxygen is a crucial factor second only to water itself. A dissolved oxygen level that is too high or too low can harm aquatic life and affect water quality. Non-compound oxygen, or free oxygen (O2), is oxygen that is not bonded to any other element. Dissolved oxygen is the existence of these free O2 molecules in the water. The molecule of oxygen bonded in a water molecule (H2O) is in a compound and does not count toward dissolved oxygen levels (Rivsbech et al., 1988).

Dissolved oxygen from the atmosphere
Dissolved oxygen goes into the water through the air or as a byproduct of a plant. From the air, oxygen can slowly diffuse across the water’s surface from the nearby atmosphere, or be assorted in rapidly through aeration, whether natural or man-made. Water aeration can be brought about by wind (creating …show more content…

That is to say, an increase in blood CO2 concentration which leads to a decrease in blood pH will result in hemoglobin proteins releasing their load of oxygen. Conversely, a decrease in carbon dioxide provokes an increase in pH, which results in hemoglobin picking up more oxygen. Since carbon dioxide reacts with water to form carbonic acid, an increase in CO2 results in a decrease in blood pH. This effect facilitates oxygen transport as hemoglobin binds to oxygen in the gills, but then releases it in the tissues, particularly those tissues in most need of oxygen. When a tissue's metabolic rate increases, its carbon dioxide production increases (Sambrook et al.,
