    Abstract: 本計畫於2002年台南都會地區冬春兩季PM2..5大氣氣膠微粒化學組成及酸鹼性，探討其不同特性組成及其時空變異。結果顯示，氣膠微粒組成均以SO42-、NO3－、NH4+為主要之化學成分。春季氣膠之NH4+質量濃度高於冬季，且其他成分K+、Ca2+、Mg2+濃度總和春季亦明顯高於冬季，顯示都會地區塵土污染春季較嚴重。
    PM2.5氣膠微粒之酸鹼性於冬季日夜平均之NR值為1.22 ~1.63 呈略鹼性，春季日夜平均之NR值為4.17 ~4.33 呈鹼性。都會地區冬季日間氣膠SOR及NOR為0.41、0.14較春季日間0.3、0.03高，顯示日間氣膠微粒之酸性較夜間強，冬季日間都會地區之光化反應較春季強烈，硫物種的光化轉化速率遠大於氨物種。
