| Outline of Final Research Achievements |
Combining data of the metal concentration in PM2.5 obtained at intervals of 10 minutes by the gas exchanger and ICP - MS / MS with the backward trajectry, and conducting concentration weighted trajectry analysis, interesting information could be extracted. On March 19, 2016 measurements, Mn and Fe concentrations in PM 2.5 of Matsue City, Shimane Prefecture, on this day were obviously strongly influenced by northern China and Mongolia. On the other hand, Sb and Pb were strongly influenced by over Japan, especially from the Kansai region. In order to solve the problem of transboundary pollution, it is very important to quantify the contribution rate of each emission source, and the method used in this research is useful for separating origins.
