大気汚染の現状と防止対策

抄録

The causes of the atomosphere contamination are mainly due to the fixed sources as waste materials from industrial plants and the moving sources as ventilation gas from automobiles.
The counter plan for the fixed sources are partly decided by using the high quality fuel, controlling the firing process and developing more efficient and simpler apparatus to gather cinders and to reject injurious contamination. In addition to those processes, It is necessary to diffuse the gas materials into the higher sky and to the wider field. The main contamination materials are composed of the oxidized materials of sulfur and mitrozen floating in the form of small particles.
For ventilation gas from the moving sources the counterplan is more difficult than case of the fixed sources. This problem should be more promptly studied in future.
