A sample with a relative stability of 1 is perfectly stable, meaning that the dissolved oxygen level will not change even if the sample is exposed to a large amount of organic matter. A sample with a relative stability of 0 is completely unstable, meaning that the dissolved oxygen level will drop to zero very quickly if the sample is exposed to a large amount of organic matter.<\/p>\n<p>The total oxygen required to satisfy BOD is the amount of oxygen that is needed to break down all of the organic matter in the sample.
