| Research Abstract |
Uptake abilities of 80 plant species for toluene, benzene and methacrolein were investigated. Decreases in the concentrations of benzene and toluene were observed for 5 and 16 species, respectively. By using a fumigation system and proton-transfer reaction mass spectrometry, we measured their uptake rates of toluene, benzene and methacrolein. Normalized uptake rates of benzene and toluene were 0-1 mmol m-2 s-1 for Hydrangea macrophylla, Lithocarpus edulis, Cinnamomum camphora, Nerium oleander, Ilex rotunda, and Viburnum odoratissimum but the uptake rate of toluene was highest (3 mmol m-2 s-1) for Prunus yedoensis.
