Vedclass · Answer

(C) $(BOD)$ is a measure of the amount of dissolved oxygen required by aerobic microorganisms to break down the organic matter present in a given volume of water. It is an effective indicator for biodegradable organic pollutants. Domestic sewage,dairy industry effluents,and sugar industry effluents contain high amounts of biodegradable organic matter. However,effluents from the petroleum industry contain non-biodegradable hydrocarbons and toxic chemicals that cannot be easily broken down by aerobic decomposers. Therefore,$(BOD)$ is not a reliable index for measuring pollution in water bodies receiving effluents from the petroleum industry.
