Urban air quality and health in China

Urban air pollution is one of the most visible environmental problems in China. In this paper, we use emission inventory data to assess the air quality and health effects in the Chinese city of Shijiazhuang. A spatial model is developed to identify the sources of emissions and to estimate population exposure to high ambient concentrations. Dose-response functions are used to quantify the impact on human health. Our results show significant health costs associated with Shijiazhuang's high concentration of sulphate, a fine particulate matter originating mainly from coal consumption. Policy implications are explored by evaluating alternative pollution control options. The use of cleaner coal is found to be the most cost effective in improving urban air quality and reducing human exposure.
