Air Pollution effects health of people living downwind. If any cost arises as a result of that pollution, that cost is usually borne by individuals that were harmed, not the emitting facility. Air pollution is regarded as one of the highest priorities in environmental protection in both developed and developing countries. This book presents the social costs estimate for the adverse human health effects resulted from ambient air pollution. It aids decision makers to set priorities in the public health relevance of pollution abatement. The book describes the measuring and valuing the impacts of air pollution on health. Estimates of the health damages associated with air pollution are important because they can provide both an impetus for environmental controls and a means of evaluating the benefits of specific pollution control policies.
