Abstract Rime-ice and snow samples were collected at mountain sites in Kyushu, Japan during the winter of 1994, and both soluble and insoluble substances in the melted rime-ice were analyzed by ion chromatography, inductively coupled plasma-mass spectrometry (ICP/MS) and analytical electron microscopy, in order to find the evidences of long-range transport of air pollutants from the cities of the East Asian region. The relationships between Al, which is most often used as an index of soil components, and other elements were examined. The positive correlation was found between Al and three elements (Ti, Mn, Ba). Therefore, behaviors of these elements in rime-ice may be similar to that of soil particles. Furthermore, it was possible to classify the elements into three groups with the relation between a lead isotope ratio and concentration ratio of lead and zinc (Pb/Zn). In addition, numbers of particles were found in the rime-ice. The particles around 1 μm in diameter were considered to be the combustion products of coal, whose Pb/Zn were similar to that of previous survey report in Korea. The existent forms of chemical species in rime-ice will become an important factor, when we consider the origin of air pollutants transported over long distances in the East Asian region.
