Abstract

In order to investigate the long-range transfer mechanism of inorganic small spherical particles in wet-depositions on mountains and remote areas along the Japan Sea in Honshu Island, Japan in 2014 and 2015, other than the summit of Mt. Kajigamori in Shikoku Island, Japan, the residue was obtained with a 0.45 μm pore-sized filter and a single-particle analysis was carried out for ones below 3 μm by using a Low-Vacuum Tabletop SEM-EDX. Particles were classified in six categories according to their compositions. In this work, it was found that a new category type of distribution patterns of the particles (Al-Si particle) was presented, and proposed that depended on the 24 h back-trajectory in Russia near the coast area of Japan Sea. Relationship between classification and back trajectory of air mass was investigated and discussed.
