That dissolved oxygen is utilized by the aquatic organisms for respiration. The heterotrophic microorganisms present inside the water also utilizes the dissolved oxygen.
The BOD value is then calculated with the depletion and the size on the sample used. The DO readings are generally in areas for every million (ppm).

The test tells us the amount of iron during the blood is bound to transferrin, the leading protein within the blood that binds to iron and transports it all through the body.
