The characteristics of the road-side particles were examined. The elemental concentrations of aerosol particle collected on the road-side were measured both by PIXE analysis as a bulk sample and SEM-EDX analysis as individual particle sample. For the data set of SEM-EDX, cluster analysis was applied.

On an average, more than 80% of the aerosol particles are consisted of lighter elements such as C, O, N and H. Main metal components contained in the roadside particles were Si, Ca, Fe and Al that were mainly originated in soil.
