Biology Question on Biodiversity and Conservation
Limit of BOD prescribed by Central Pollution Control Board for the discharge of industrial and municipal waste water into natural surface water, is:
A
< 3.0 ppm
B
< 10 ppm
C
< 100 ppm
D
< 30 ppm
Answer
< 10 ppm
Explanation
Solution
The limit of BOD (Biochemical Oxygen Demand) prescribed by the Central Pollution Control Board (CPCB) for the discharge of industrial and municipal wastewater into natural surface water typically falls within the range of < 10 ppm. This limit can vary depending on the specific regulations and water quality standards in a given region, but it is common for such discharges to have a BOD level of less than 10 parts per million (ppm) to protect the water quality and aquatic ecosystems.
So, the correct option is (B): < 10 ppm
