Outline of Annual Research Achievements

本研究の目的は、(1)中央ヨーロッパ(チェコ・プラハおよびバックグラウンドサイト)と中部日本(春日井市)の郊外で採取する大気エアロゾル試料を分子レベルで分析し、有機物の組成の季節的・地域的特徴を明らかにする、(2)異なるサイトで採取した大気エアロゾル試料中に共通に存在する有機物トレーサーを検索する、また、地域的に特徴的なトレーサーを見いだす、(3)中央ヨーロッパにおける都市域と非都市域における有機物組成の違いを明らかにすると共に、それらの特徴をこれまで報告されているアジア域や西部北太平洋の大気エアロゾルの化学組成と比較し、共通性・主な違いを探し出す、(4)有機エアロゾルの組成の比較研究から、有機物の起源、生成メカニズム、光化学的エイジングに関する情報を入手する、また、安定炭素同位体の測定からそれらの議論をサポートするとともに、新しい知見を発見することである。

本年度は、エアロゾル試料中の炭素・窒素の測定と、その安定炭素・窒素同位体比の測定を続行し、信頼性のある結果を生み出した。これらの研究の進捗状況から、本研究は概ね順調に進展していると判断された。本研究の第一報は、2019年3月にAtmos. Chem. Phys.誌に掲載されたが、次なる論文を執筆するために、これまでのデータをまとめて論文作成の準備をした。また、中部大学で採取した大気微粒子の試料分析を行い、データの取得をおこなった。しかし、まだ未測定の試料もあり再度の来日も考えている。
