【植物と微粒子】2年間、水溶性微粒子を植物に与えたら?Effect of water-soluble particles on growth of plants (2 years)

JOURNAL: Atmospheric Environment (2014)http://www.sciencedirect.com/science/article/pii/S1352231014000405 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 of…

【植物と微粒子】森林へのエアロゾル沈着過程を解明. Deposition process of particles into forests

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。
