Olympics – 1984 – Los Angeles Summer Games Special – The Effects of SMOG In Los Angeles


The word “smog” was coined in the early 20th century as a combination of the words smoke and fog to refer to smoky fog, its opacity, and odor….which was originally intended to refer to what was sometimes known as “pea soup fog”….which had been a familiar and serious problem in London from the 19th century to the mid-20th century. This kind of visible air pollution is composed of nitrogen oxides, sulphur oxides, ozone, smoke or dirt particles….with less visible particles such as CFC’s. Human-made smog is derived from coal emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions.

Modern smog, as found for example in Los Angeles….as talked about by ABC Sports Frank Gifford and Kathleen Sullivan in this video herewith….is a type of air pollution derived from vehicular emission from internal combustion engines….and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog….whereas in certain other cities such as Delhi…. smog severity is often aggravated by stubble burning in neighboring agricultural areas. The atmospheric pollution levels of Los Angeles, Beijing, Delhi, Lahore, Mexico City, Tehran and other cities are increased by inversion that traps pollution close to the ground. It is usually very highly toxic to humans and can cause severe sickness, shortened life or death.
