Particulate matter and urban air pollution affect the human body and can lead to death. Epidemiological studies should consider exposure to pollutants and the diverse responses of individuals, depending on their sensitivity to the pollutants.
In this study, air pollution measurements were obtained hourly at measuring stations operated by national and local governments to increase the reliability of the measured values. A β-ray absorption method was used to analyze the measurements of fine dust and determine the particulate matter content.
The air pollution data were log-linear, thereby enabling a comparison of data from different time periods. The comparison was made by focusing on the period of the implementation of Seoul's fine dust policy. It was observed that the cancer incidence rate decreased after the implementation of the policy. The data on individual characteristics were obtained from a survey of Seoul citizens conducted from 2015 to 2016 using indicators such as quality of life and the social trust of Seoul citizens.
The survey on the living environment and residence indicated that 80% of the heads of households were men. Women had a greater dissatisfaction than men with their residential, economic, and social environments. The survey questions on well-being were related to elements of internal and external environments, such as air pollution, noise, and fine dust.
颗粒物和城市空气污染会影响人体健康，甚至导致死亡。在进行流行病学研究时，应考虑到污染物的暴露情况，以及个体对污染物的敏感程度不同而产生的多样化反应。
本研究在全国和地方政府运营的测量站每小时进行一次空气污染测量，以提高测量值的可靠性。β射线吸收法用于分析细粉尘的测量值，并确定颗粒物含量。
空气污染数据呈对数线性，因此可以比较不同时间段的数据。通过关注首尔细颗粒物政策实施期间进行了比较。实施该政策后，癌症发病率有所下降。个体特征数据来自于 2015 年至 2016 年对首尔市民进行的一项调查，使用了生活质量和首尔市民社会信任度等指标。
对生活环境和居住情况的调查显示，80%的家庭户主为男性。与男性相比，女性对居住、经济和社会环境的不满程度更高。幸福感调查问题与空气污染、噪音和细粉尘等内外环境因素有关。
