PRODUCT INFORMATION SHEET 

BIOCHEMICAL OXYGEN DEMAND (BOD)

 

 

The capacity of organic material to consume dissolved oxygen (DO) as it decomposes is one of the most important effects of water pollution, as oxygen is necessary for the maintenance of fish, mollusks, and other aquatic life. The BOD test is used to measure the rate at which decomposable organic material will consume oxygen in water. The test was designed as a laboratory model of the deoxygenating effect of wastes on receiving waters and is essentially a bioassay involving the measurement, under standard conditions, of oxygen consumed by living microorganisms as they utilize the organic material for food.

 

The standard five-day BOD test consists of enclosing a sample of water plus the test sample in an air tight bottle, incubating it at 20°C in the dark for five days, and measuring the amount of DO present before and after incubation. The difference in DO is the BOD5 and is often expressed as parts per million (ppm) or milligrams per day (mg/d) when measuring the BOD load of an effluent stream. When measuring the BOD of a chemical substance, it is more commonly measured in percent. By definition, sucrose (sugar) has a BOD of a 100%. These terms always refer to a quantity of oxygen and not to organic matter as such. The higher the BOD5, the greater the amount of deoxygenating effect the substance has in receiving waters. It should be noted that in case of accidental spills into waterways, most substances undergo a tremendous dilution effect; therefore, their BOD5 would be reduced accordingly.

 

The BOD5 test is complex by nature and is subject to interpretation; therefore care must be exercised when comparing the BOD5 of various substances. Several substances and their typical BOD5 as determined in our laboratory are listed below.
