BOD (Biochemical Oxygen Demand)

The quantity of oxygen consumed by aerobic microorganisms during the decomposition of organic matter in a water sample is defined as the Biochemical Oxygen Demand (BOD).

BOD is the most commonly used parameter for determining the oxygen demand in water. The BOD value gives an indirect measure of biodegradable organic compounds. This indicates the degree of organic water pollution although it is not an accurate quantitative test.
