The photochemical smog does not generally contain :
The photochemical smog does not generally contain :
- NO
NO2
SO2
- HCHO
The Correct Option is C
Solution and Explanation
Photochemical smog contains:
Ozone, nitric oxide, organic compounds, nitrogen dioxide, formaldehyde.
∴ SO2 is not the part of photochemical smog.

Concepts Used:
Atmospheric Pollution
- The pollution that directly harms living organisms is the atmospheric pollution, air is more essential than food when it comes to the survival of life on earth. Atmospheric pollution is, consequently, a major concern for life on the planet. The most common type of air pollution that affects much of the world is Smog (smoke + fog).
- Pollution is the outcome of undesired changes in the environment with harmful effects on plants, animals, and humans. The element that causes pollution is commonly known as pollutants.
- Pollutants may be solids, liquids, or gases that are present in large quantities in nature and produced due to human activities or natural circumstances.
- For instance, materials such as dichlorodiphenyltrichloroethane (DDT), heavy metals, chemicals, plastic materials, nuclear waste, etc., once disclosed to the environment it is difficult to remove.
Causes of Atmospheric Pollution:
There is a number of factors that contribute to the pollution of the environment. Some of the major causes of atmospheric pollution are given below -
- Industrial waste
- Usage of pesticides
- Deforestation
- Combustion of fuels
- Nuclear Explosions
- Use of Toxic Solvents
