Biochemical oxygen demand (BOD) is a measure of organic materials present in water, BOD value less than \(5 \mathrm{ppm}\) indicates a water sample to be
- A rich in dissolved oxygen
- B poor in dissolved oxygen
- C highly polluted
- D not suitable for aquatic life
Answer & Solution
Correct Answer
(A) rich in dissolved oxygen
Step-by-step Solution
Detailed explanation
The amount of oxygen required by bacteria to break down the organic matter present in a certain volume of a sample of water, is called biochemical oxygen demand (BOD). The amount of BOD in the water is a measure of the amount of organic material in the water, in terms of much…
