- The type of air pollution caused by photochemical smog is formed through the reaction of solar radiation with airborne pollutants like nitrogen oxides and volatile organic compounds.
- These compounds, which are known as primary pollutants, are often introduced into the atmosphere through automobile emissions and industrial processes.
Ultraviolet light can split nitrogen dioxide into nitric oxide and monatomic oxygen, this monatomic oxygen can then react with oxygen gas to form ozone. - Products like ozone, aldehydes, and peroxyacetyl nitrates are known as secondary pollutants.
- The mixture of these primary and secondary pollutants forms photochemical smog.
Thus, the correct answer is option C.
