| 摘 要： | 目的：大气中SO2污染会对人体健康带来潜在的危害，因此有必要了解广州市区SO2污染与人群暴露水平。方一法：通过AIRQUIS模型计算结果，结合2000年人口分布，分析2000年广州市市区SO2污染的人群暴露水平及其特征。结果：2000年广州市市区绝大多数地区环境空气质量符合二级标准，市区总人口数量中95．9％的人暴露于SO2年平均值一、二级标准的浓度范围内，而且市区SO2的浓度变化对SO2大的工业点源的排放变化较为敏感。结论：控制城区大点源排放将是降低SO2人群暴露水平的主要措施。

| Abstract: | Objective: As there is a potential health impact of SO 2 pollution on human body,it is important to understand the characteristics of population exposure to SO 2 in the urban area of Guangzhou. Methods: The modeling calculation result of AIRQUIS model and the population distribution data in 2000 were used to analyze the exposure level to SO 2 pollution in Guangzhou. Results:In 2000 the air quality in most areas in Guangzhou accorded with the 2nd national standard and 95.9% of total population exposed to the annual average SO 2 concentration which was in the range of the 1st and the 2nd standard values. Variation in industrial exhaust from large point sources may result in significant change of population exposure to high level of SO 2 pollution. Conclusion: Abatement of emission from large industrial point sources will be an important way to reduce the population exposure to SO 2 in urban area. |
