URBAN AIR QUALITY AND PUBLIC HEALTH IN CHINA : A TALE OF TWO CITIES

Air pollution is perhaps the most visible environment problem in today's urban life in China. This paper uses air quality data collected in two Chinese cities to assess the environmental health effects of urban air pollution. Spatial models are developed to identify the sources of damage and estimate population exposures to high ambient concentrations of particulate and sulfur dioxide emissions. Dose-response functions are used to quantify the impact on human mortality and morbidity. Our simulation results show significant health costs associated with air pollution in Chinese cities, which are an order of magnitude larger than the estimated damages to agro-ecosystems. Air pollution control options are explored by evaluating the costs and benefits of alternative abatement policies.
