Air pollution can be defined as the harmful gases in the air that we breathe. Pollution can be caused by natural sources or as a result of human activities. Natural pollutants include: dust, pollen, smoke from forest fires, and bacterial and volcanic action. Nevertheless, human activities are the main cause of air pollution. Major sources of air pollution are industrial (factories and power stations) at 36% and on-road transportation at 26%. Currently, the number of vehicles on roads is constantly rising, leading to producing more pollutants. The most common pollutants in transportation are nitrogen oxides, carbon monoxide, sulpher dioxide, hydrocarbons and particulate matters.
