| Research Abstract |
PM_<2.5> mass concentration in the Northern Kyushu area is dominated by the influx of regional air pollution from the Asian continent throughout the year. Organic pollutants in the particulate state such as PAHs also appeared to be transported from the Asian continents in spring, fall, and winter. However, urban air pollution in Fukuoka added some inorganic nitrate in winter, and organic pollutants in summer. Single particle analysis employing LISPA-MS revealed the internal mixture state of Pb and other metallic species such as K, Fe, Na, and Zn is often observed in aerosol collected at Fukue in spring.
