The oxygen used in meeting the metabolic needs of aerobic microorganisms in water rich in organic matter (as water polluted with sewage)—called also biological oxygen demand, oxygen demand.
1 | 2. One of the most important nutrients, which affected BOD in aquatic systems in the recent past is phosphate pollution from American households. It was discovered decades ago that the addition of phosphorous to soaps and detergents made them clean better.  Biochemical Oxygen Demand-BOD. Biochemical oxygen demand or B.O.D. is a chemical procedure for determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period.  Medical Definition of BIOCHEMICAL OXYGEN DEMAND. : the oxygen used in meeting the metabolic needs of aerobic microorganisms in water rich in organic matter (as water polluted with sewage)—called also biological oxygen demand, oxygen demand. Britannica.com: Encyclopedia article about biochemical oxygen demand. noun biochemical oxygen de·mand \-di-ˌmand\. : the oxygen used in meeting the metabolic needs of aerobic microorganisms in water rich in organic matter (as water polluted with sewage)—called also biological oxygen demand, oxygen demand. Definition of BIOCHEMICAL OXYGEN DEMAND. : the oxygen used in meeting the metabolic needs of aerobic microorganisms in water rich in organic matter (as water polluted with sewage). ADVERTISEMENT. noun biochemical oxygen de·mand \-di-ˌmand\. Definition. Standard method for indirect measurement of the amount of organic pollution (that can be oxidized biologically) in a sample of water. BOD test procedure is based on the activities of bacteria and other aerobic microorganisms (microbes), which feed on organic matter in presence of oxygen. You may want to take a biological oxygen demand to see if you are doing any damage to the surrounding environment. 5 people found this helpful. You should be taking many tests of the biological oxygen demand to make sure that your factory is not doing any harm. biological oxygen demand (BOD).

First Known Use of BIOCHEMICAL OXYGEN DEMAND. noun biochemical oxygen de·mand \-di-ˌmand\. : the oxygen used in meeting the metabolic needs of aerobic microorganisms in water rich in organic matter (as water polluted with sewage)—called also biological oxygen demand, oxygen demand. Definition of BIOCHEMICAL OXYGEN DEMAND. : the oxygen used in meeting the metabolic needs of aerobic microorganisms in water rich in organic matter (as water polluted with sewage). ADVERTISEMENT. noun biochemical oxygen de·mand \-di-ˌmand\. Additional Info. The first step in a BOD determination is taking a water sample from the test area and diluting it with a known volume of distilled water. The solution is then thoroughly shaken to insure oxygen saturation.  Home Find by Parameter. Biological Oxygen Demand (BOD) is a laboratory test that calculates the oxygen demand of a discrete sample incubated over five days, used to indicate water quality. Definition. Biological Oxygen Demand (BOD) is a laboratory test that calculates the oxygen demand of a discrete sample incubated over five days, used to indicate water quality. Alternative recognised methodologies such as TOC (Total Organic Carbon) allow continuous measurement and the prediction of poor water quality.
