BOD of waste water is estimated by measuring the amount of
BOD of waste water is estimated by measuring the amount of
Show Hint
\[
\boxed{
\text{BOD}=\text{Measure of biodegradable organic pollutants in water}
}
\]
Higher BOD indicates greater organic pollution.

- Biodegradable organic matter
- Oxygen evolution
- Oxygen consumption
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall the meaning of BOD.
BOD (Biochemical Oxygen Demand) is an index of the amount of biodegradable organic matter present in water.
It represents the oxygen required by microorganisms to decompose this organic matter.
\[
\boxed{\text{Higher biodegradable organic matter } \Rightarrow \text{Higher BOD}}
\]
Step 2: Choose the correct option. Hence, BOD is estimated by measuring the amount of \[ \boxed{\text{Biodegradable organic matter}.} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
Step 2: Choose the correct option. Hence, BOD is estimated by measuring the amount of \[ \boxed{\text{Biodegradable organic matter}.} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
