Question 4 of 8
4. Question
Q4. {Envi – Degradation} Consider the following statements regarding ‘Photochemical smog’:
- It occurs most prominently in urban areas that have large numbers of automobiles.
- It is aggravated by dampness and a high concentration of suspended particulate matter in the air.
- Photochemical smog results in the formation of ground-level ozone, a harmful air pollutant.
Which of the statements given above are correct?
Correct
Explanation
Statement 1 is correct
- Photochemical smog is also known as “Los Angeles smog”.
- Photochemical smog occurs most prominently in urban areas that have large numbers of automobiles (Nitrogen oxides are the primary emissions).
- Photochemical (summer smog) forms when pollutants such as nitrogen oxides (primary pollutant) and organic compounds (primary pollutants) react together in the presence of sunlight.
Statement 2 is incorrect
- Sulfurous smog is also called “London smog,” (first formed in London). Resulting from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal, this type of smog is aggravated by dampness and a high concentration of suspended particulate matter in the air.
- Dampness and a high concentration of suspended particulate matter (SPM) in the air can actually reduce the formation and severity of photochemical smog, rather than aggravate it, as:
- High humidity can lead to the formation of clouds, which can block sunlight and reduce the photochemical reactions that form smog.
- High concentrations of SPM can scatter sunlight, reducing the amount of UV radiation available for photochemical reactions. This can, in turn, reduce the formation of photochemical smog.
Statement 3 is correct
- Photochemical smog results in the formation of ground-level ozone, a harmful air pollutant.
- Nitrogen Dioxide + Sunlight + Hydrocarbons = Ozone (Ozone in stratosphere it is beneficial, but near the earth’s surface it results in global warming as it is a greenhouse gas).
