報告名称 東アジアにおける酸性物質及びオゾンの生成と沈着に関する観測と環境影響評価
報告概要 本研究は東アジアを対象に,対流圏内の酸性物質やオゾン濃度の推移などを対象としたとした環境観測と環境影響評価である。オゾン濃度の変動調査は以下のリモート観測地点(利尻,八方,隠岐,沖縄,モンディ,スリナカリン,インタノン,黄山)でオゾン・一酸化炭素の通年連続観測を継続し,本年度は特にタイでの地表オゾンデータの解析と,オゾン濃度とその季節変動につき欧州-東アジアの比較検討をした。大気微量成分の高感度連続測定装置の開発と野外観測では,光化学オゾンの生成プロセスや酸性/塩基性ガスの長距離輸送プロセス解明用として高感度連続測定装置を開発し,野外観測に供して評価した。これらには,レーザー誘起蛍光法によるHOxラジカル連続測定装置,ガスクロマトグラフ/不イオン化学イオン質量分析法によるPAN連続測定装置,不イオン化学イオン質量分析法によるアンモニア連続測定装置,レーザー誘起蛍光法による二酸化窒素連続測定装置などを含む。
