BOD is a measure of
- A ozone depletion in the stratosphere due to too many free radicals.
- B suspended particulate matter in the air causing lung problems.
- C pesticides which are non-biodegradable in the soil and water.
- D organic material present in water needing dissolved oxygen to break them down depleting oxygen content in water.
Answer & Solution
Correct Answer
(D) organic material present in water needing dissolved oxygen to break them down depleting oxygen content in water.
Step-by-step Solution
Detailed explanation
BOD is a measure of organic material present in water needing dissolved oxygen for decomposition Hence, depleting the oxygen content in water.
