Abstract: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 hig… Show more
