Identify the INCORRECT statement about Biological Oxygen Demand (BOD).
- A It is the amount of dissolved oxygen required by microorganisms for decomposing organic matter.
- B It is expressed in milligram of oxygen per litre of water.
- C More the level of microbial pollination higher the BOD.
- D Higher the BOD, higher the level of oxygen in the water.
Answer & Solution
Correct Answer
(D) Higher the BOD, higher the level of oxygen in the water.
Step-by-step Solution
Detailed explanation
Biochemical Oxygen Demand (BOD) is the amount of dissolved oxygen required by microorganisms for decomposing the organic matter present in water. It is expressed in milligram of oxygen per litre (mg/L) of water. High BOD indicates intense level of microbial pollution, not higher levels of oxygen.
