Can anyone explain to me how smog forms over major cities?
Most of the pollution was created from the burning of coal in space heating (boilers), cooking and transportation. Under suitable conditions, the smoke and sulphur dioxide produced can combine to form Industrial Smog. Today, Industrial smog is far less common, but the burning of fossil fuels such as Petroleum can create another atmospheric problem known as photochemical smog.
This condition developes when Primary Pollutants(Oxides of Nitrogen and volatile organic compounds created from fossil fuel combustion) combine under the influence of sunlight to give off a mixture of many different and hazardous chemicals know as Secondary Pollutants.
These conditions mainly occur in large cities
Smog usually is produced through a complex set of photochemical reactions involving volatile organic compounds (VOC's) and nitrogen oxides in the presence of sunlight that result in the production of ozone. Smog-forming pollutants come from many sources, such as automobile exhausts, power plants, factories, and many consumer products, including paints, hair spray, charcoal starter fluid, solvents, and even plastic popcorn packaging. In typical urban areas, at least half of the smog precursors come from cars, buses, trucks, and boats.
