$BOD$ increases

Vedclass · Answer

(A) $BOD$ (Biochemical Oxygen Demand) is defined as the amount of dissolved oxygen required by bacteria to decompose the organic matter present in a certain volume of a sample of water. As the quantity of organic pollutants increases in a water body,the amount of organic matter available for decomposition by microorganisms also increases. Consequently,microorganisms consume more dissolved oxygen to break down this organic matter,leading to an increase in the $BOD$ value. Therefore,$BOD$ is directly proportional to the amount of organic pollutants in water.

What changes take place in the $BOD$ of a water body with an increasing quantity of organic pollutants?
