本研究的主要目的是评估墨西哥城大都市人群可能经历的细颗粒物（PM10）户外暴露的程度。随着地理信息系统（GIS）的使用，空间分辨PM10。分发的数据已生成并与当地人口挂钩。PM10浓度超过24小时空气质量标准150 mug/m3的天数为16%，在某些地方，超过50 mug/m3的年度空气质量标准几乎是其两倍。本文描述的基本方法集成了空间人口和空气质量数据库，允许各种空气污染减少方案的评估。达到年度空气质量标准将意味着典型居民的年算术平均浓度降低14 mug/m3。在墨西哥城，人类暴露于颗粒物（PM）与死亡率和发病率有关;降低这种污染物的浓度水平将意味着死亡率和发病率的降低以及这种影响的相关成本。这一方法对于评估墨西哥城环境都市委员会目前实施的改善空气质量举措的潜在效益至关重要。
The main goal of this study was to evaluate the magnitude of outdoor exposure to fine particulate matter (PM10) potentially experienced by the population of metropolitan Mexico City. With the use of a geographic information system (GIS), spatially resolved PM10. distributions were generated and linked to the local population. The PM10 concentration exceeded the 24-hr air quality standard of 150 mug/m(3) on 16% of the days, and the annual air quality standard of 50 mug/m(3) was exceeded by almost twice its value in some places. The basic methodology described in this paper integrates spatial demographic and air quality databases, allowing the evaluation of various air pollution reduction scenarios. Achieving the annual air quality standard would represent a reduction in the annual arithmetic average concentration of 14 mug/m(3) for the typical inhabitant. Human exposure to particulate matter (PM) has been associated with mortality and morbidity in Mexico City; reducing the concentration levels of this pollutant would represent a reduction in mortality and morbidity and the associated cost of such impacts. This methodology is critical to assessing the potential benefits of the current initiative to improve air quality implemented by the Environmental Metropolitan Commission of Mexico City.
