Significance of bod
Most natural waters contain small quantities of organic compounds. Aquatic microorganisms have evolved to use some of these compounds as food. Microorganisms living in oxygenated waters use dissolved oxygen to oxidatively degrade the organic compounds, releasing energy which is used for growth and reproduction. Populations of these microorganisms tend to increase in proport… WebThe BOD test is a method-defined (empirical) technique. Consequently, the method must be followed carefully, and must be performed consistently from day to day and analyst to analyst. Potential errors can be encountered in each of the following steps in the BOD test. Evaluate the results of samples, GGA, blanks and duplicates and report.
