摘要：The concentration of total suspended particule matter (TSP), the 9-stage particule size of TSP or suspended particule matter (SPM) was measured in Umedashinmichi (heavy gasoline car traffic) and Dekijima (relatively heavy diesel car traffic). The concentration of TSP or many polluted materials (Tar, SO24-, NO3-) in Dekijima was higher than that in Umedashinmichi, while that of the polluted materials in TSP of Dekijima was less than the concentration of Umedashinmichi. The high content of Fe or Mn in TSP of Dekijima indicated the TSP of Dekijima to be influenced possibly more by solid sources than that of Umedashinmichi. Moreover, the considerable influence of solid sources in Dekijima was suggested from analytical results on the particule size of TSP and SPM.
