What happens when we spray water-soluble “air pollution” particles to plants for 2 years? 水溶性 「大気汚染」 粒子を植物に2年間散布したらどうなるでしょう?

JOURNAL: Atmospheric Environment (2014) Effects of 2-years exposure to (sub-micron) ammonium sulfate particles on growth and gas exchange rates of Fagus crenata (ブナ), Castanopsis sieboldii (スダジイ), Larix kaempferi (唐松) and Cryptomeria japonica (スギ) seedlings •No significant effect of the particles on growth was observed after 2 years.•Net photosynthetic rates of 3 species were not significantly changed.•Net photosynthesis…

Deposition process of aerosols into forest/ 森林へのエアロゾル沈着過程を解明

Particulate matter strongly adsorbed onto leaf surfaces is not washed away by rainfall and contributes to the EC (Elemental Carbon) flux. Leaf-surface particles must be included when evaluating the dry and total fluxes of particulate matter, in particular for water-insoluble constituents such as EC. 葉面に強く「付着」した粒子状物質は降雨によって洗い流されず、EC(元素炭素)フラックスに寄与する。粒子状物質、特にECのような水不溶性成分の乾燥流束および全流束を評価する場合には、葉表面粒子を含めなければならない。
