日本大城市的空气污染与健康影响之间的相互关系是一个巨大的挑战，因为关于接触污染、健康影响和混合原因的不确定性的数据有限。本文用统计方法分析了定量关系（排放量与空气质量之间以及空气质量与健康影响之间）的方法; 1974年至2007年日本空气污染减排政策的相关性。本章讨论了一个循序渐进的方法来确定排放量，空气质量和健康影响之间的直接相关性。总排放量（NOx，PM）（从固定和移动的源）和空气质量（NO2，TSP）之间的关系被认为是显着的。排放量和空气质量的相关性分析表明，NOx和PM水平恶化，根据NO2的增加。当空气污染物和健康影响的类型（认证，死亡率，恢复和新登记）之间的相关性进行了检查，根据认证的区域，观察到一个反比关系。空气质量（NO2）和健康效应之间的关系被认为是显着的。利用1989 ~ 2007年的数据进行哑变量分析，发现当NO2浓度升高时，新登记患者、死亡率和新登记患者均呈上升趋势。
The correlation between air pollution and health effects in large Japanese cities presents a great challenge owing to the limited availability of data on the exposure to pollution, health effects and the uncertainty of mixed causes. A methodology for quantitative relationships (between the emission volume and air quality, and the air quality and health effects) is analysed with a statistical method in this article; the correlation of air pollution reduction policy in Japan from 1974 to 2007. This chapter discusses a step-by-step methodology of determining the direct correlation between emission volumes, air quality, and health effects. The relationship between total emissions (NOx, PM) (from both stationary and mobile sources) and air quality (NO2, TSP) was found to be significant. The correlation analysis of emission volume, and air quality suggests that NOx and PM levels worsen according to increases in NO2. When the correlation between the air pollutant and the type of health effect (certified, mortality, recovery, and newly registered) was examined according to the certified area, an inverse relationship was observed. The relationship between air quality (NO2) and health effect was found to be significant. When NO2 worsens, certified patients, mortality rates and newly certified patients increase, according to the data from 1989 to 2007 with dummy variable analysis.
