During April 1980 aerosol particles were sampled at five locations in Japan for a week which included an especially strong dust storm derived from the Asian mainland. Time sequence sampling by streakers and PIXE analysis for multi-elemental concentrations in 2.4 h time steps recorded the passage of the storm over Japan. At Niigata three distinct components could be identified: soil dust represented by Fe, sea spray represented by Cl, and air pollution represented by S. The three had different arrival and disappearance times although they were all present during most of the storm.
