biochemical oxygen demand

Amount of dissolved oxygen taken up by micro-organisms in a sample of water. Since these micro-organisms live by decomposing organic matter, and the amount of oxygen used is proportional to their number and metabolic rate, BOD can be used as a measure of the extent to which the water is polluted with organic compounds.
