| biochemical oxygen demand |
A standard measure of water pollution, especially those contaminated by sewage and industrial waste. It is the amount of oxygen needed by bacteria and other microorganisms to decompose organic matter in the water. Higher values of BOD are associated with higher pollution. It is a process that occurs over a period of time and is commonly measured over a period of five days, referred to as BOD5 measured in mg/liter.
