| Outline of Research at the Start |
Epidemiological evidence on the health effects of transported air particulate matter such as Asian Dust is limited. Existing studies have reported mixed results. We proposed a study to quantify the short-term associations of local and transboundary air particulate matter with daily mortality in Japan.
|
| Outline of Final Research Achievements |
This study accomplished several goals. Firstly, it devised a method to discern daily particulate matter sources in Japanese cities, utilizing aerosol maps and wind trajectory analyses, adapted from European research on East Asian desert dust events. Secondly, it investigated long-term variations of daily air pollutants and their associated mortality burden in Japanese cities, providing crucial insights into the changing short-term mortality burden of air pollution. Thirdly, it explored particulate matter's interaction with high ambient temperature to jointly affect human health, addressing concerns related to rising global temperatures due to climate change. Finally, it established a database containing exposure information on desert dust events and air pollutants in Japan, essential for ongoing international collaborations with European research groups to investigate the global health burden of desert dust storms.
