All of the major cities of the United States and most of the major cities worldwide have serious air quality problems. The air pollution problem arises from rapidly increasing auto,truck and bus traffic as well as burgeoning industrial development. many valleys, small towns and suburban communities are made vulnerable to such pollution because of natural air inversion. There is abundant evidence that the levels of air pollution in these major cities present serious health problems as evidenced by the increasing rates of emphysema, chronic bronchitis, and respiratory disorders in city dwellers and from experimental data on laboratory animals exposed to ambient air pollution.
