松山，大阪，つくばで観測した浮遊粉じh中金属元素濃度比による長 距離輸送と地域汚染特性の解析

摘要

To evaluate the effect of trans-boundary and regional air pollution mgarding aemsol, we collected aerosols from 14 Marth 2007 through 28March 2007 in Matsuyama , Osaka and Tsukuba. From the concentration of metal components and the ratio of metal concernerons , weevaluated the effect of anthropogenic pollutants and soil elements to chemical constituents in aemsols, based on the backwarcl trajectoryanalysis. As for metols of anthropogenic origin, the concentration levels and variations were quite different in firme sampling sites. A highPb/Zn ratio observe in Matsuyama was consistent with previous report for Beijing. In Matsuyama, the low V/Mn ratios were observed whenthe air mass taveler over central or northem China; on the other band, the high V/Mn ratios were observed regarcling local air pollution Metalconcentration ratio of Tsukuba almost conesponded to those of the crust and the soilfrom the analysis conducted of Pb/Zn, V/Mn , La/Sm andLa/V in the aemsols, the validity of the metal concentration ratios as the index of long-range transported and regional air pollution wereclarified.
