Air Pollution Control

Abstract

Pollutants—foreign material in the air—can be man made or occur naturally, and are concentrated where people are concentrated. Pollution is injurious to health and its prevention places an economic burden on the citizen. Amendments to the Clean Air Act, passed in 1970 and in 1977, have been utilized to control air pollution. They encompass different strategies which have met with varying success. Progress to date has been significant but it has been effected in those areas most amenable to control. Further emission reductions from automobiles, and transportation measures and programs will be more difficult to accomplish, but the challenge has been presented. The decision is up to the citizenry as to whether there shall be clean air for all—and at what price.
