Preferred Label : biochemical (biological) oxygen demand;
Detailed label : biochemical (biological) oxygen demand (BOD);
IUPAC synonym : biological oxygen demand;
IUPAC acronym : BOD;
IUPAC definition : The amount of oxygen, divided by the volume of the system, taken up through the respiratory
activity of microorganisms growing on the organic compounds present in the sample
(e.g. water or sludge) when incubated at a specified temperature (usually 20 C) for
a fixed period (usually 5 days, BOD5). It is a measure of that organic pollution of
water which can be degraded biologically. In practice, it is usually expressed in
milligrams O sub 2 /sub per litre.;
