[Term] Biochemical oxygen demand [Explanation] 
Biochemical oxygen demand is the amount of oxygen required for complete (aerobic) biological decomposition of a material. The standard laboratory method (BOD5) tests the amount of dissolved oxygen consumed in a closed aqueous system over a five-day period. It is a fairly direct, but time-consuming measure of biodegradability of liquid streams.
