抄録/ポイント： 三酸化硫黄(SO_3)は,大気硫酸(H_2SO_4)形成,酸性雨形成,および他の大気物理化学的プロセスのための重要な化合物である。昼間,SO_3は主にOHラジカルによるSO_2の光酸化から生成する。しかし,OHラジカルが不足しているとき,早朝と夜間のSO_3源は完全には理解されていない。大気SO_3とH_2SO_4を検出するために,硝酸塩-CI-APi-LTOF(化学イオン化-大気圧界面長-飛行時間)質量分析計を用いて,冬と夏2019年の都市北京における2つの現場測定の結果を報告する。結果は,SO_3のレベルが夏より冬に高く,特に早朝(~05:00~08:30)と夜間(約18:00~05:00)に観測された高いSO_3レベルを示した。SO_2,NO_x,黒色炭素,交通流,および大気イオンの分析に基づいて,SO_3が交通関連黒色炭素の表面でのSO_2の触媒酸化から形成できることを示唆した。この以前に未同定のSO_3源は早朝に顕著なH_2SO_4形成をもたらし,従ってサブ2.5nmの粒子形成を促進する。これらの知見は,中国の巨大都市における二次粒子形成を緩和するための都市SO_3の理解と政策の策定に役立つであろう。Copyright 2020 American Chemical Society All rights reserved.
