The elemental composition of individual particles was determined by using a scanning electron microprobe equipped with an energy-dispersive X-ray analyzer (SEM-EDX). According to elemental compositions for below 2.5 μm(PM2.5), 85.4% of the particles in March 2010 were Si-rich . For the 2.5 to 10μm (PMc), 80.9% of the particles were also Si-rich. According to the detail classification of Si-rich particles, the composition of Si-rich particles of surface soil samples collected at Ulaanbaatar and Han Uul in Mongolia were similar to the particles samples collected at Higashiosaka. The origin of Asian dust storm particles collected at Higashiosaka might be transported from the Mongolian desert. The back trajectory analysis supported these results. The number of Asian dust storm particles below 2.5μm adsorbing sulfur oxides was increased from 2007 to 2010., application/pdf}, pages = {41--49}, title = {2010年に東大阪市で捕集された黄砂粒子の個別粒子分析}, volume = {26}, year = {2014}, yomi = {ナカグチ, ユズル and フジワラ, ツカサ and タケダ, コウイチ and サノ, イタル} }
