[An assessment of PM2.5 related health risks and impaired values of Beijing residents in a consecutive high-level exposure during heavy haze days].
It has important scientific value and practical significance for urban atmospheric air pollution control and people health protection to carry out health risk assessment as well as impaired value assessment of short-term high concentrations of air pollution. Using the Poisson regression model and environmental valuation method, this study estimated the health risks and impaired values of Beijing residents in a consecutive high-level PM2.5 exposure during the heavy haze pollution occurred from January 10th to 15th, 2013. The results show that, substantial health risks due to PM2.5 air pollution were occurred in six pollution days, including 201 cases of premature deaths, 1,056 and 545 cases of hospital admissions for respiratory and cardiovascular diseases, 7,094 and 16,881 cases of pediatric and internal outpatients each, 10,132 cases of acute bronchitis and 7643 cases of asthma respectively. Correspondingly, approximate 489 (95% CI: 204-749) million RMB health-related economic loss was evaluated, of which more than 90% was attributable to premature deaths, acute bronchitis and asthma. It is recommended that health risks and economic losses can be reduced through early health warning and timely medical intervention for various groups of people with different health endpoints.
