Transboundary pollution is not limited to inorganics but also organic materials (recognized as bioaerosols). The elemental composition of the particles themselves is not easily affected by the surrounding environment or the differences in chemical composition. Still, there are technical issues with the analysis of organic matter in PM samples collected in a short period. To address this issue, we investigated the use of Ion Beam Induced Luminescence (IBIL) analysis, one of the analytical methods that could be combined with particle-induced X-ray emission (PIXE) method, well known elemental composition analysis technique. In earlier research, we have reported the application of IBIL to analyze organic compounds such as NADH and riboflavin as indicators of bioaerosols. This study investigated whether it is possible to analyze and evaluate PM (bioaerosol) collected from the general atmosphere in a unit of time by using IBIL analysis for PM samples collected from the general atmosphere.
