Regional And Local Air Pollutions Of Organic Aerosols In Highly-Populated City Of East Asia

A significant amount of organic aerosol particles are known to be transported from East Asia, but it is still unclear if a contribution of the pollutant transported from East Asia is comparable with that of the pollutant emitted from local emission sources in a large city located at the downstream of East Asia. In this study, particulate polycyclic aromatic hydrocarbons (PAHs) and n-alkanes were measured in Fukuoka City and Fukue Island between 2010 and 2011. From comparisons between the results of Fukuoka City and Fukue Island, the contribution from the transboundary air pollution in Fukuoka City is discussed.
