What is the difference between sulphurous smog and photochemical smog?
Sulfurous smog, also known as London smog, develops due to high concentration of sulfur oxides in the air. Photochemical smog is produced when sunlight reacts with oxides of nitrogen and at least one volatile organic compound (VOC) in the atmosphere.

Sulfurous smog generally occurs in areas where there is more industry, or places that rely on fossil fuel combustion for energy and heating. Photochemical Smog is generally found in urban and industrial areas and occurs when hydrocarbons from vehicle exhaust react with sunlight to produce ozone.
