Introduction:
Photochemical smog is a type of air pollution that occurs when sunlight reacts with certain chemicals in the atmosphere. It is characterized by the presence of high levels of ozone, nitrogen oxides, and volatile organic compounds. In this question, we are asked to determine the correct statements regarding photochemical smog.
Statement 1: Photochemical smog is a term used to describe air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere.
This statement is correct. Photochemical smog is formed when sunlight interacts with pollutants such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of oxygen. This reaction leads to the formation of ground-level ozone and other secondary pollutants.
Statement 2: One of the primary components of photochemical smog is stratospheric ozone.
This statement is incorrect. Stratospheric ozone is a beneficial component of the atmosphere that helps to protect life on Earth from harmful ultraviolet (UV) radiation. It is primarily found in the stratosphere, which is the layer of the atmosphere above the troposphere where photochemical smog forms. The primary components of photochemical smog are ground-level ozone (formed through the interaction of sunlight with NOx and VOCs) and other secondary pollutants such as peroxyacetyl nitrate (PAN).
Conclusion:
In conclusion, the correct statement regarding photochemical smog is that it is a term used to describe air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere. The statement that one of the primary components of photochemical smog is stratospheric ozone is incorrect.

The Formation of Smog
- Photochemical smog (smog) is a term used to describe air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere.
- One of the primary components of photochemical smog is ozone.
- While ozone in the stratosphere protects earth from harmful UV radiation, ozone on the ground is hazardous to human health.
- Ground-level ozone is formed when vehicle emissions containing nitrogen oxides (primarily from vehicle exhaust) and volatile organic compounds (from paints, solvents, printing inks, petroleum products, vehicles, etc.) interact in the presence of sunlight.
