Record number: 1, Textual support number: 1 OBS
The weight of oxygen taken up by the total amount of organic matter in a sample of water without distinguishing between biodegradable and non-biodegradable organic matter. The result is expressed as the number of parts per million (or milligrams per litre, or grams per cubic metre) of oxygen taken up from a solution of boiling potassium dichromate in two hours. The test has been used for assessing the strength of sewage and trade wastes. 3, record 1, English, - chemical%20oxygen%20demand
