Research Abstract |
Measurement methods of carbonaceous component in atmospheric aerosols were investigated in order to obtain more precise data. Pretreatment of filter used for sampling aerosols and analysis of elemental, organic, and carbonate carbons were discussed. In addition, field observation was carried out at a background site where trans-boundary atmospheric pollution could be observed, and trans-boundary pollution was examined from the viewpoint of behavior of carbonaceous aerosols.
