The main pollutants of air pollution are sulfur oxides, nitrogen oxides, carbon monoxide and carbon dioxide (Holman, 1999). The main causes of air pollution are the smoke from power plants, motor vehicles, wildfire and fumes from paint and spray. According to Holman
(1999), some pollutants are emitted directly into the atmospheres which are primary and others are formed in the air as a result of chemical reactions with other pollutants and atmospheric gases which are secondary pollutants. Carbon monoxide and sulfur dioxide are examples of primary pollutants, while ozone is an example of a secondary pollutant (Holman
1999). Some pollutants, such as nitrogen dioxide (NO 2) and some particulate matter, are both primary and secondary pollutants. They are both emitted directly into the atmosphere, and formed from other (Holman, 1999).6

Caughey and Dawn). Today, over 53.7% of its population lives in cities; by 2020 it is projected that a whole 60% of the population will live in cities (Xinhuanet, 2014).
