Définition
Sens technique
Amount of oxygen required to oxidize organic matter (biodegradable) with a biological process (oxidation of biodegradable organic matter by bacteria). The biological oxygen demand (BOD) is an index of water pollution that assesses the biodegradable fraction of the carbonaceous pollution load in wastewater, and is usually calculated after 5 days at 20°C and in darkness: it is then called BOD5.
