Why can formation of atmospheric ozone in the troposphere be linked with urban pollution?
Answer and explanation
Correct answer: Because it can form through reactions of pollutant gases in the presence of sunlight
Tropospheric ozone is a secondary pollutant: it is not usually emitted directly in large amounts, but forms when nitrogen oxides and volatile organic compounds react in sunlight. These precursor gases are often released by vehicles, industries and fuel combustion, making ozone a characteristic component of photochemical smog in urban areas. Option B is incorrect because oceans are not its only source, C confuses ozone with nitrogen, and D mistakes a chemical pollutant for a non-chemical form of pollution.
