PREFACE
In recent years our environment has been dealt with on a very serious level. Today’s generation has demanded that something be done to preserve our environment. They are speaking out and asking countless questions. In many ways the environment has been damaged beyond repair. The focus today is on repairing and preserving what remains.
The physical aspects of air pollution and its effects on society is the theme of this unit. A teacher would be free to approach the topic from several directions. For example, one could discuss each pollutant individually in terms of sources, methods of emission, how it is affected by chemical reactions in the atmosphere, adverse effects, and ultimate fate, Others may prefer to emphasize the functional approach because in most regions where air pollution is considered a problem, a pollutant coexists with other pollutants and there is a continual evolution of the nature of the atmosphere through chemical reactions.
