Outline of Annual Research Achievements

本研究では、人間活動の影響を強く受ける東アジアとその風下域である西部北太平洋の大気エアロゾルの焦点を当て、その化学組成と吸湿特性の関係をあきらかにすることを目的とした。小笠原諸島・父島で2001年より2012年までの長期間にわたり採取した海洋エアロゾルの吸湿特性をタンデムDMA吸湿特性装置にて測定し、その吸湿成長率と化学組成の関係を解析した。父島で採取したエアロゾル試料を水抽出し、ネブライザーにより生成した粒子の吸湿特性(吸湿成長率Gf)を吸湿特性タンデムDMA装置を用いて測定した。更に、エアロゾルの化学組成と吸湿特性を比較した結果、粒子のGfは水溶性有機物(WSOC)の割合の増加や、塩素ロスの増大とともに減少することを発見した。この結果は、有機物が微粒子の吸湿特性を低下させていることを意味している。更に、春のカルシウム濃度が高い試料では、Gfは低くなることを見いだし、その理由としてシュウ酸カルシウムの生成により粒子の水溶性が減少することを明らかにした。これらの成果は、アメリカ地球物理学会のJ. Goephys. Res.誌に投稿され、受理された。
また、海洋エアロゾル中に無機イオンの長期変動を解析したところ、硫酸塩の濃度が2006年までは増加傾向を示したが、その後、減少に転じたことが判明した。この減少は、中国における火力発電所の脱硫装置が本格的に稼働した時期と合致している。発生源における硫黄排出量の削減が西部北太平洋の大気質に影響していることが明らかとなった。また、硫酸の減少に伴って塩素ロスは少なくなると予想され、微粒子の吸湿特性も今後変化(増加)するものと予測される。一方、有機物の濃度については減少傾向が認められずその原因については、現在解析中である。

Strategy for Future Research Activity

小笠原諸島・父島における水溶性ジカルボン酸を含む有機エアロゾルの動態を2001年から2013年まで解析し、その変動傾向を明らかにする。また、その原因について、気候変動・地球温暖化の観点から、また、気象データを駆使することにより解析する。海洋エアロゾル中の糖類の長期変動の解析を進め、その長期変動と大気輸送・気候変動との関係を解析する。これらの成果を論文として国際誌に投稿する。
