Methodological Research on the Health-based Risk Assessment on Air Pollution / 环境与健康杂志

ABSTRACT

Objective To get comprehensive and quantitative evaluation of the impact of ambient air pollution on human health. Methods The approach recommended in this paper is a quantitative estimate on the health impact from exposure to air pollutants based on the internationally accepted quantitative risk assessment framework and the per unit increase in mortality or morbidity due to per unit increase of air pollutants levels. Results A schematic diagram of health-based risk assessment on air pollutants is presented. Calculation for excess deaths and excess disease cases is also provided. Conclusion This approach could be used for comparing the health effects associated with exposure to air pollutants of various Chinese cities in different time periods and is also useful in the priority setting of air pollution intervention and improvement measures and health-based cost benefit analysis.
