广州市SARS传播与空气污染相关性研究

探讨SARS传播与空气污染的关系.根据广州市及周边城市自SARS发病以来主要空气污染物的监测统计结果,结合广州市SARS发病例数和气象观测资料等进行相关性研究,并与香港进行对比.结果表明,广州市SARS发病数与发病前5 d的可吸入颗粒物污染浓度密切相关,香港SARS发病数与发病前1～2 d的可吸入颗粒物污染浓度密切相关.研究表明,SARS发病数与发病前空气污染状况有密切关系.

Correlation research between SARS' propagation incidence and concentration of inhalable particulates in air in Guangzhou

The present paper studys the relation between SARS spreading and air pollution. Based on the monitoring of the statistic results of air pollutants in Guangzhou and its surrounding cities since the SARS was induced and discovered in the area, the authors of this paper has been keeping their observation by comparing the air pollution situation with the incidence of SARS cases as well as the meteorological (or climatic change) data. Then the authors make a carefully designed analysis of the correlation between SARS propagation and the air pollution in Guangzhou and Hong Kong area. From the observation and statistical results, it is found that there does exist a significant correlation between the incidence of SARS and the concentration of inhalable particulates in the air five days before in Guangzhou. In addition, similar correlation was also done between the incidence of the SARS and the concentration of inhalable particulates in the air one-to-two days before in Hong Kong. Thus it can be concluded that there ought to exist some kind of close correlation between the SARS propagation incidence and the air pollution concentration.
