Question:
Which of the following gas is an indoor air pollutant?
Which of the following gas is an indoor air pollutant?
Show Hint
Radon is an important indoor air pollutant to remember, especially due to its radioactive nature and health hazards like lung cancer.
Updated On: Apr 28, 2025
- Nitrogen dioxide
- Radon
- Sulfur dioxide
- Carbon dioxide
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Radon is a naturally occurring radioactive gas that can accumulate in indoor environments, especially in basements and poorly ventilated buildings. It seeps from soil and rock into the air and is a known carcinogen.
Nitrogen dioxide, sulfur dioxide, and carbon dioxide are also air pollutants but are primarily associated with outdoor pollution from vehicles and industrial emissions rather than being characteristic indoor pollutants.
