Question

dissolved oxygen defination

Answer 1

Dissolved Oxygen

Dissolved oxygen means that how much oxygen is present in water. A good level of dissolved oxygen Is essential for aquatic life.Fish in waters containing excessive dissolved gases may suffer from "gas bubble disease"; however, this is a very rare occurrence. The bubbles or emboli block the flow of blood through blood vessels causing death.


Why Dissolved Oxygen is Important

Dissolved oxygen analysis measures the amount of gaseous oxygen (O2) dissolved in an aqueous solution. Oxygen gets into water by diffusion from the surrounding air, by aeration (rapid movement), and as a waste product of photosynthesis.
