How does photochemical smog differ from industrial smog?

In: Pollution, Air Pollution [Edit categories]

Answer:

Industrial smog occurs when the smoke and sulfur dioxide produced from burning coal merges with fog and creates a yellowish-brown-colored haze close to ground level.

Photochemical smog forms as the result of increased usage of all fossil fuels, including gasoline and the burning of trees and organic waste. When the primary pollutants from these react with sunlight, they also form hazardous secondary pollutants.
