Outline of Final Research Achievements

To investigate formation mechanisms of atmospheric secondary organic aerosol (SOA) affecting climate and human health, we developed an online instrument for the analysis of organic compounds present in aerosol particles by a combination of a home-made thermal desorption instrument and a proton transfer reaction-mass spectrometer. We studied fragmentation patterns of organic compounds with carboxyl, hydroxy, and carbonyl groups by measurements of single component aerosol particles. Then, we generated SOA particles using a smog chamber to monitor temporal changes of oxocarboxylic acid and dicarboxylic acids present in particles. We also detected highly oxygenated molecules and dimers in generated SOA particles. Furthermore, we observed atmospheric particles to detect dicarboxylic acids existing in particles.

Academic Significance and Societal Importance of the Research Achievements

世界では質量分析計を活用したオンライン大気粒子分析装置が新たな研究手段として注目を集めている。本研究は陽子移動反応質量分析計の改良によってオンライン大気粒子分析装置の開発を試みたものである。有機化合物のフラグメント化の規則性や粒子生成実験や大気観測から見出された課題は技術的に有意義な情報である。SOAのオンライン計測によりオフライン分析と似た有機化合物が検出されたことは、従来のオフライン分析に基づく知識の定性的な有効性を示しており学術的意義がある。さらに本研究でSOA中に二量体を検出した成果は、モデル研究者と共同で進めている大気微小粒子状物質予測モデルの高精度化にも貢献した。
