本研究有两个目的：（1）开发一种正式的方法，以最佳地定位一个密集的空气污染监测站网络;（2）根据这些监测数据和相关的土地利用，人口和生物物理信息，得出一个暴露评估模型。以前的研究都是以一种随意的方式定位监视器，倾向于将监视器放置在交通“热点”或主观认为感兴趣的区域。我们应用我们的方法定位在加拿大多伦多的100个二氧化氮监测仪。该方法确定的地点代表土地使用、交通基础设施和高危人群的分布。我们从监测项目中得出的暴露评估在城市内部范围内产生了合理的估计。最佳定位监测器的方法可能具有广泛的适用性，污染监测网络的设计，特别是测量交通污染物与细尺度空间变异。(c)2005爱思唯尔有限公司保留所有权利。
This study addresses two objectives: (1) to develop a formal method of optimally locating a dense network of air pollution monitoring stations; and (2) to derive an exposure assessment model based on these monitoring data and related land use, population, and biophysical information. Previous studies have located monitors in an ad hoe fashion, favouring the placement of monitors in traffic "hot spots" or in areas deemed subjectively to be of interest. We apply our methodology in locating 100 nitrogen dioxide monitors in Toronto, Canada. Locations identified by the method represent land use, transportation infrastructure and the distribution of at-risk populations. Our exposure assessments derived from the monitoring program produce reasonable estimates at the intra-urban scale. The method for optimally locating monitors may have widespread applicability for the design of pollution monitoring networks, particularly for measuring traffic pollutants with fine-scale spatial variability.
