Webenters a system faster than it can be degraded, dissolved oxygen levels can drop below the minimum level required by aquatic organisms. In extreme cases, all of the dissolved oxygen may be removed, making the stream “anoxic”. When this happens, most organisms die, thus adding more BOD to the system and further increasing the oxygen demand. WebSignificance of BOD. The significance of BOD is that it is a measure of the amount of dissolved oxygen that is used up by microorganisms as they break down organic matter in water. The higher the BOD, the more oxygen that is being use up and the more polluted the water is.
