But air pollutant unhealthful 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.
