Air quality has a very close relationship with the quality of human health. Air pollution could decline the quality of human health by causing many kinds of respiratory or non-respiratory diseases. Sources of air pollution could come from the emission of road vehicles, smoke from factories and fuel burning activities. Today many dangerous pollutants emitted from the human daily activities are not only threatening to the human health but also other living organisms on earth.

On the contrary for the comfort reason of the human life, they need vehicles for transportation, factories for producing the needed products and fuel burning as energy source for many purposes. Even they are also as an important factor to run and support the economic growth for almost every country in the world.
