| 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).
