| biochemical oxygen demand |
a measure of the amount of oxygen necessary to decompose organic materials in a volume of water. As the amount of organic waste in water increases, more oxygen is used, resulting in a high BOD.

| biochemical oxygen demand |
the oxygen required for the biochemical degradation of organic material (carbonaceous) and the oxygen used to oxidize inorganic material such as sulfides and ferrous iron. In other words, a measure that indicates the degree to which dissolved oxygen levels would change in a stream based on the contributions of organic matter.

| biochemical oxygen demand |
The amount of dissolved oxygen consumed by micro-biological action when a sample is incubated, usually for 5 days at 20 deg. C. (in the UK expressed as BOD5 ). In some countries the BOD test is carried out over differing periods such as 7 days (BOD7), and 10 days (BOD10).

| biochemical oxygen demand |
A quantitative measure of the oxygen needed by bacteria and microorganisms for the biological oxidation of organic wastes in a unit volume of waste water. BOD is generally measured in milligrams per liter (rng/1) of oxygen consumed over a five-day period. Although complete biological decomposition of, organic waste requires about 20 days, the five-day BOD is about two-thirds of the total oxygen requirement and, therefore, is a practical measure of waste concentration. ...
