Smog: causes & effects

The term smog was first created in London in 1905 and is a combination of smoke and fog. Today the term refers to the mixture ofpollutants but is primarily made up of ground-level ozone. The main chemicals include carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), Nitrogen oxides (NO) and the ozone (O3). Smog is created when these hydrocarbons and nitrogen dioxide mixes with sunlight. Most of these sources are derived from motor vehicle emissions and industrial waste. Smog is an overabundance of dust and gases, such as carbon dioxide and sulfur dioxide, in the air. Smog can cause or aggravate health problems such as asthma, emphysema, chronic bronchitis and other respiratory problems as well as eye irritation and reduced resistance to colds and lung infections. This paper discusses about the major causes & effects of Smog.
