| Research Abstract |
In this study, airborne particulates were collected simultaneously at Shenyang(China), Kanazawa and Wajima(Japan). Nine polycyclic aromatic hydrocarbons(PAH) and three nitropolycyclic aromatic hydrocarbons(NPAH) in the particulates were determined. The average concentrations were higher in cold season than in warm season. A meteorological analysis indicated that the air samples collected at Wajima, a background site on the Noto Peninsula, Japan, in cold season were transported mainly from Northeast China over the Japan Sea. Both the concentration ratios of PAH and NPAH were similar to those in Shenyang in Northeast China which located along the air transportation route to Wajima, but not in Kanazawa which near Wajima. These results strongly suggest that most of the atmospheric PAH and NPAH at Wajima in cold season were long range transported from Northeast China. And, no significant changes of PAH and NPAH compositions were observed during their transportation.
