(BOD) is a measure of the amount of oxygen needed for microorganisms to convert organic matter to inorganic matter. It is typically measured as the amount of oxygen consumed in laboratory tests over a five-day period at 20 degrees C.

| biochemical oxygen demand |
The quantity of oxygen-demanding materials present in a sample as measured by a specific test. A major objective of conventional wastewater treatment is to reduce the biochemical oxygen demand so that the oxygen content of the water body will not be significantly reduced. Although BOD is not a specific compound, it is defined as a conventional pollutant under the federal Clean Water Act.

| biochemical oxygen demand |
a method of determining the amount of oxidizible material in water, by examining the amount of dissolved oxygen which remains after the sample has been incubated under set conditions. BOD is important because injection of high BOD wastes into water can consume such amounts of oxygen that organisms in the water die.
