为了在流行病学研究中评价空气污染与发病率和死亡率之间的关系，必须确定人口的暴露量。一般而言，环境空气监测网络是这些研究的接触数据来源。在这项研究中，我们开发的方法来定义人口暴露区域，代表空气污染物浓度的变化最小。我们评估了纽约州小于2.5 μ m（PM2.5）和10 μ m（PM10）的颗粒物和臭氧（O-3）浓度的时空变化。PM2.5和臭氧分析的结果表明，区域传输的程度很大，并显示每个监测器周围100英里和50英里的区域浓度一致。PM10分析表明，该污染物的时间和空间变化不大，采用较大的区域。纽约州卫生部已将PM2.5、PM10和臭氧的暴露表征区域用于生态流行病学调查。这项工作是在疾病控制和预防中心的环境公共卫生跟踪赠款下进行的。
To evaluate the relationship between air pollution and morbidity and mortality in epidemiological studies, the exposure of populations must be defined. Generally, ambient air monitoring networks are the source of the exposure data for these studies. In this study, we developed methods to define population exposure regions that represent minimal variation in air pollutant concentrations. We evaluated the spatial and temporal variation in concentrations for particulate matter less than 2.5 mu m (PM2.5) and 10 mu m (PM10) and ozone (O-3) across New York State. The results from the PM2.5 and ozone analysis indicate a significant degree of regional transport and showed regions of consistent concentrations of 100 and 50 miles, respectively, around each monitor. PM10 analysis indicated little temporal and spatial variation for this pollutant and larger regions were adopted. The exposure characterization regions for PM2.5, PM10, and ozone have been used in ecological epidemiological investigations by the New York State Department of Health. This work was conducted under the Environmental Public Health Tracking grant from the Centers for Disease Control and Prevention.
