Biochemical Oxygen Demand - EOLSS
Biochemical oxygen demand (BOD) is also sometimes referred to as biological oxygen demand, but the latter term is considered inappropriate by many scientists and engineers. These terms are widely used to define the microbial use or consumption (i.e. demand) of oxygen during the aerobic oxidation of electron donors such as readily
