A Study on the Air Pollution Status and Health Effects in Tokyo

This study introduces the current status of air pollutants and health effects in Tokyo, Japan. The medical cost support system for air pollution-related diseases implemented by local governments in Tokyo was also introduced. Through a correlation analysis between the annual concentration of air pollutants (PM2.5 SO2, NO2) and the number of deaths from major cardiopulmonary diseases, it was proved that the higher air pollutant concentration, the more people died from acute myocardial infarction, cerebral infarction, cerebrovascular disease, and pneumonia. As a result of calculating the relative health risk of PM2.5 in three regions (Ogasawara, Shinjuku and Tamashi) in Tokyo, compared Ogasawara (a remote island with clean air), Shinjuku and Tamashi have a relatively high risk of respiratory diseases caused by air pollution. Finally, the results of this study are expected to contribute to efforts to reduce air pollutants such as PM2.5 in other metropolitan areas and to formulate policies to improve citizens' health.
