BOD gives an indication of the biodegradable organic material present in a sample of water. The dissolved oxygen concentration is measured before and after an incubation period of 5 days and the BOD is calculated in mg per liter from the difference.

Biochemical oxygen demand (BOD) is an indicator for the concentration of biodegradable organic matter present in a sample of water.  BOD Measures the rate of oxygen uptake by microorganisms in a sample of water at a fixed temperature and over a given period of time. Samples are kept at 20 ºC in the dark and tested for dissolved oxygen (DO) after five days. The loss of dissolved oxygen in the sample, once correction have been made for the degree of dilution, is called the BOD5
