Abstract
The Taiwan EPA evaluated the pollutant uptake efficiencies of three tree species in various environmental and temporal conditions, i.e., camphor tree (Cinnamomum camphora), Formosan michelia (Michelia compressa), and rose wood (Pterocarpus indicus). During summer mornings, the three trees absorbed NO2 at only 51, 6, and 14% respectively of the rates of 3-yr-old trees. One large camphor tree with a height of 10.5 m can remove 0.13 kg/yr of toxic NO2 gas from the atmosphere. There was a highly significant difference between the young and old trees for the NO2 deposition velocities in Formosa michelia and rosewood, but not in camphor trees. In general, old trees had lower uptake rates for NO2 gas than young trees. This is an abstract of a paper presented at the 14th International Union of Air pollution Prevention and Environmental Protection Associations World Congress 2007 (Brisbane, Queensland 9/9-13/2007).
