In order to provide bases for the control of air pollutants in Korea, the author figured out the trend on the annual increase of air pollutants emitted in the process of combustions, and estimated the amounts of air pollutants of the future years from 1975 to 1981. 1) In 1973 the consumption rate of coal was 1.2 times of that of fuel oil. The consumption rate of them would be same in 1975 and 1977. However, the rate of fuel oil would exceed that of coal in 1979. Incontrast with the rate in 1979. The one of coal would be increased faster and faster to show reverse trend of consumption in 1981. 2) The estimated amounts of air pollutant emissions in the years of 1973, 1975, 1977, 1979 ana 1981 were 1,561,800, 1,921,700, 2,253,300, 2,769,000, and 3,145,700 tons respectively. These indicated that the amount of air pollutants in 1981 would be about 2 times of that in 1973. 3) The amounts of sulfur oxides emissions in 1981 would be 2.3 times of that in 1973, nitrogen oxides 2.2 times, carbon monoxide 1.7 times, particulate 2.0 times and hydrocarbon 2.0 times. 4) The estimated amounts of air pollutant emissions per unit area($km^2$) in the years of 1965, 1971, 1975 and 1980 were 5.2, 14.5, 19.5 and 28.7 tons respectively. These indicated that the amount of air pollutant emissions per unit area would increase 5.5 times in 1980 comparing the one in 1965.
