Total suspended particulate samples collected on the day of a yellow sand storm were chemically and externally researched. Scanning electron microprobe observation showed the accumulated square-built form of the mineral particles in the sample from the day of the yellow sand storm, while chemical analysis suggested rich calcium and iron content in the yellow sand sample. Samples collected on other days in contrast contained higher levels of sulfuric and nitrate anions. Calculation of the Fe/Mn ratio of the particulate samples suggested that the Fe/Mn ratio of the yellow sand sample was close to that of soil in the Chinese desert area as recorded in the literature. Moreover, the PAH concentration in the yellow sand sample was rather lower than in the other samples. It was therefore concluded that the yellow sand particles collected on April 2 to 3 in Osaka City were not derived from a specific polluted area but rather came directly from the Chinese desert area.
