“…In Japan, many studies [9][10][11][12] on the influence of long-range transport have been performed. For example, Kikuchi et al, reported that when air mass was transported from northeastern China, fog contained Kosa as a insoluble substances.…”

Particulate matter (PM) was collected at the Hachimantai mountain range in northern Japan. In the present study, the origin and transportation course of the heavy metal elements were discussed for PM fine and PM coarse , determined by using PIXE (Particle Induced X-ray Emission) and back trajectory analyses. The result shows that the PM fine emitted mainly from artificial sources, compared with the PM coarse from natural sources, since the Enrichment Factor (EF) value and S/K ratio of PM fine was one order higher than that of PM coarse . The origin of Pb in PM at Akita Hachimantai mountain range has both of the anthropogenic and the metal refining origins, using the analysis of Pb/Br. Furthermore, from result of back trajectory analysis when the air mass was transported over the Japanese Islands, the air mass was mainly passed over the large-scale industrial area in Japan. The origin of As and Se were mainly gasoline and coal combustion, and were transported from Chinese continent and/or Korea peninsula.

Fog water samples were collected at the Akita Hachimantai mountain range in northern Japan from August to September 1997 and from June to September 1988 to 2000 to investigate the pollution mechanism of fog. Ionic components and insoluble substances in fog water were analyzed using ion chromatography and particle induced X-ray emission (PIXE) analysis, respectively. Combining a 72 h back trajectory and principal component analysis (PCA) to chemical analysis data elucidated the effect of the transport course of an air mass on samples insoluble substances and ionic components. When the air mass was transported from northern China to the Hachimantai range, the nss- SO 42- was greater than in other cases. That fog contained "Kosa" as an insoluble substance from northern China. Our PCA analysis revealed that the score of PC1 (which was about –0.5) was a measure of containing "Kosa".
