Social awareness and concern about environmental pollution and air resource quality have intensified in recent years. Harmful air pollution effects to humans, animals and plants have produced public demands and action for more restrictive pollution control laws and resource management programs. Air quality management and air pollution control decisions are dependent upon economic analysis on the nature and magnitude of benefits and costs associated with air pollution reductions. Analyses of economic effects over time are necessary to evaluate the effectiveness of existing air pollution control agencies, programs and laws, to establish new short and long run programs and research priorities in air pollution, and to determine the level of air quality and pollution control activity which can be realistically attained. Evaluating the benefits of air pollution control is one of the most difficult tasks limiting economic analysis of this environmental resource problem. The benefits of reducing air pollution may be viewed as the prevention or reduction in damages incurred from its effects, that is, the avoidance of loss. Empirical analysis of direct air pollution effects to living organisms including people, animals and plants involves the identification, quantification, and economic evaluation of damages oc curring due to the existing level of air quality.
