Question:
The BOD value of clean water is X. The maximum concentration of cadmium recommended in drinking water is Y. X and Y respectively are
The BOD value of clean water is X. The maximum concentration of cadmium recommended in drinking water is Y. X and Y respectively are
Show Hint
BOD is an indicator of organic pollution in water. Lower BOD means cleaner water.

- $>$ 5 ppm, 0.005 ppm
- $>$ 5 ppm, 0.05 ppm
- $<$ 5 ppm, 0.05 ppm
- $<$ 5 ppm, 0.005 ppm
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Clean water has a BOD (Biochemical Oxygen Demand) value of less than 5 ppm. The permissible concentration of cadmium in drinking water is limited to 0.005 ppm to avoid toxicity.
