Award: Charging state of particles collected from air 大気中から捕集した粒子の帯電状態を調べた(学会賞)

呼吸により人体に入る微粒子の帯電状態が注目された。大気中に浮遊する微粒子の帯電状態を評価できる手法を考案。The importance of electrostatic charging state to particle deposition in the human airways has been suggested. We developed a measurement method of electrostatic charging state of individual ambient aerosol particles

水溶性の大気汚染粒子を森林樹種に2年間散布した Water-soluble “air pollution” particles to Forest Tree Species

Four Japanese forest tree species were exposed to submicron ammonium sulfate particles for two years. While growth and photosynthesis in Fagus crenata, Castanopsis sieboldii, and Larix kaempferi remained unaffected, Cryptomeria japonica showed both increased and decreased photosynthetic responses. This study highlights species-specific sensitivity to sulfate (aerosol) particles. 4種の日本の森林樹木に、サブミクロンサイズの硫酸アンモニウム(エアロゾル)粒子を2年間散布。ブナ、スダジイ、カラマツでは成長や光合成に有意な影響は見られなかったが、スギでは光合成速度の増加と減少の両方が観察され、エアロゾル粒子への感受性が示された。
