Abstract

 Publication of PM2.5 data in Shiga prefecture has been insufficient so far, and the actual situation of PM2.5 isn't grasped.In this study, at Seta hill, Shiga prefecture, we continuously measured PM2.5 concentration and analized the component of metals and inorganic ions. Trajectories of air masses were also calculated. It was deduced that one of the main causes of PM2.5 high concentration at Seta hill was yellow dust(Asian dust). Elemental components (Al, Ca, Fe, Mg, Si) contained in yellow dust were detected from PM2.5 collected in a yellow dust day. The results of inorganic ions analysis confirmed that SO42- was more than NO3- and mainly distributed as (NH4)2SO4 in the fine particles. The results of analysis of the chemical component and calculation of the trajectories of air masses showed that high concentrations of PM2.5 except for yellow dust day were due to transboundary pollution from China and Korea, and anthropogenic SO2 emissions from domestic urban areas and volcanic SO2 emissions.
