In addition, air pollution can influence air quality. Normally, atmosphere is be of cardinal nine percent nitrogen, twenty percent atomic number 8 and one percent carbon dioxide. But air pollutant virulent air, it includes reciprocal ohm dioxide and oxide of nitrogen. For instant, Tolba (1982, P11) stated, in1970-1986, global emission rate of oxide of nitrogen increase by almost one-third, while emission of sulfur dioxide change magnitude by approximately eighteen percent.
