Vedclass · Answer

(C) $(BOD)$ is the amount of dissolved oxygen that would be consumed if all the organic matter in one liter of water were oxidized by bacteria.When sewage is mixed with river water,the amount of organic matter increases.This leads to an increase in the population of decomposer microorganisms,which consume more oxygen for the decomposition process.Therefore,the $(BOD)$ value increases as the organic pollution load increases.
