In 2022, the air pollution level of ozone (O3) in South Korea amounted to around ** parts per billion. It is up from about ** parts per billion in 2008.

This dataset includes MDA8 O3 and 24-hour NO2 concentrations measured in the Seoul Metropolitan Area from May 2018 to April 2021.

Air pollution is closely associated with the development of respiratory illness. Behavioral adaptations of people to air pollution may influence its impact, yet this has not been investigated in the literature. Our hypothesis is that people experience and learn the underlying air quality to decide their adaptation, and they have a stronger incentive to behaviorally adapt to the air quality as it deteriorates. We tested our hypothesis on a sample of approximately 25,700 individuals from South Korea from 2002 to 2013 that contained information on daily doctor’s visits due to respiratory disease. We matched individuals to the mean of the past seven-day concentration of the particulate matter of size between 2.5 and 10 micrometers (PM10) in their county of residence. We examined whether people living in counties with greater air pollution suffer less from respiratory disease when the concentration increases. For the analysis, we separated counties into quintiles based on their mean seven-day PM10, and regressed the binary indicator of a daily doctor’s visit with a resulting diagnosis of respiratory disease on the seven-day PM10 concentration of the county of residence interacted with the quintile dummies. The key findings are that a 1-standard-deviation increase in the seven-day PM10 concentration in the two lowest quintiles is associated with an increase of 0.054 percentage points in the likelihood of a doctor’s visit with a resulting diagnosis of respiratory disease, which is about 40% larger than the effect in higher quintiles, and the size of 1-standard-deviation gradually increases from 0.037 percentage points in the third quintile to 0.040 percentage points in the fifth quintile. The smaller increase in the likelihood of respiratory disease in more polluted locations can be explained by the behavioral adaptation to the environment, but the effectiveness of the adaptation seems limited among the highly polluted locations.

This information provided by Seoul Metro is about indoor air quality in subway stations managed by the Corporation. As of 2021, indoor air quality measuring devices have been installed in a total of 259 stations from Lines 1 to 8, and air quality within each station is collected on an hourly basis, nearly in real time. This information is public data for the health and safety of citizens, and measured items include fine dust (PM10), ultrafine dust (PM2.5), carbon dioxide (CO₂), formaldehyde (HCHO), carbon monoxide (CO), nitrogen dioxide (NO₂), and volatile organic compounds (VOCs), allowing for a comprehensive understanding of air pollution levels within stations.

PM2.5 air pollution of Democratic People's Republic of Korea fell by 3.84% from 31.12 micrograms per cubic meter in 2019 to 29.93 micrograms per cubic meter in 2020. Since the 1.41% climb in 2017, PM2.5 air pollution sank by 23.59% in 2020.

In 2022, the air pollution level of particulate matter (PM10) in Daegu, South Korea, amounted to approximately ** micrograms per cubic meter, a decrease from ** micrograms per cubic meter in the previous year.
