Photochemical smog pollution does not contain:
Correct answer: D. Carbon dioxide
- A. PAN (peroxyacyl nitrate)
- B. Ozone
- C. Nitrogen dioxide
- D. Carbon dioxide
Explanation
Photochemical smog is a complex type of air pollution primarily formed through chemical reactions involving pollutants released into the atmosphere. While the composition of photochemical smog can vary, it typically contains a mix of pollutants and secondary compounds. Photochemical smog is formed at high temperatures over cities and towns due to still air, emission of nitrogen oxides and carbohydrates from automobile exhausts and solar energy.
