2011-1-21  Smog is air pollution that reduces visibility.The term "smog" was first used in the early 1900s to describe a mix of smoke and fog.The smoke usually came from burning coal.Smog was common in industrial areas, and remains a familiar sight in cities today. Today, most of the smog we see is photochemical smog.Photochemical smog
