Answer 1

Biochemical Oxygen Demand (BOD) may not be good index for pollution for water bodies receiving effluents from Petroleum industry.

Explanation:

The biochemical oxygen demand (BOD) is the amount of oxygen required by aerobic decomposers for organic material decomposition. Because it comprises non-biodegradable debris, BOD is not an effective index for assessing the contamination level of water bodies receiving effluents from the petroleum industry.
