Vedclass · Answer

(A) $BOD$ stands for Biochemical Oxygen Demand. It is a measure of the amount of dissolved oxygen required by aerobic microorganisms to decompose the organic matter present in a given volume of water. If the $BOD$ of waste water is high,it indicates that there is a large amount of organic matter present,which requires more oxygen for decomposition. Therefore,a higher $BOD$ value directly correlates with a higher polluting potential of the waste water.
