Valuing the adult health effects of air pollution in Chinese cities.

China's ongoing economic growth is accompanied by a large amount of air pollution that exacts significant health and economic costs on its people. Following up on some earlier work focusing upon general mortality and child-specific health effects, this article uses a larger data set, covering more than 90 Chinese cities, along with a set of China-based epidemiological functions, to estimate some of the adult health benefits of reducing urban air pollution. Projecting future air pollution based upon current conditions, it calculates the averted mortality and morbidity effects that would result from the cleanup of particulates, sulfur dioxide, and nitrogen dioxide. The inclusion of nitrogen dioxide in our analysis is particularly important because it is a growing problem and has not been included in most of the more widely known studies that examine Chinese air pollution. Finally, the economic valuation of these pollution-related health effects is developed, using a number of recent, China-based valuation studies.
