The use of aerometric network data has been criticized before on the grounds that it might give an unreliable picture of population exposure. However, the extensive data obtained from networks is still being used for studies of health effects of air pollution. This study uses a rigorous approach in analyzing these data to test their suitability for studies of acute health effects of air pollution. New York City, with one of the most extensive aerometric networks, consisting of 40 air pollution monitoring stations, is taken as an example. Three years of hourly SO2 readings and bi-hourly readings of smokeshade have been analyzed. The use of one aerometric station to represent the daily exposure of the population of New York City as has been done in previous studies is shown to be invalid. The use of individual monitoring stations of the New York City aerometric network to represent the day-to-day exposure to SO2 and smokeshade of the populations surrounding these monitoring stations is examined, with results showing that further work will be necessary before such an approach is justified.
之前有人批评使用大气监测网络数据，理由是它可能无法可靠地反映人群暴露情况。然而，从这些网络获得的大量数据仍被用于空气污染对健康影响的研究。本研究采用一种严谨的方法来分析这些数据，以测试其是否适用于空气污染急性健康影响的研究。以纽约市为例，它拥有最广泛的大气监测网络之一，由40个空气污染监测站组成。对三年来每小时的二氧化硫读数和每两小时的烟度读数进行了分析。研究表明，像之前研究那样用一个大气监测站来代表纽约市人口的每日暴露情况是无效的。对纽约市大气监测网络中各个监测站用于代表这些监测站周边人群日常二氧化硫和烟度暴露情况进行了研究，结果表明在这种方法合理之前还需要进一步开展工作。
