Outline of Final Research Achievements

A decrease in the air pollutants concentration from the top of canopy to the forest floor was observed in the Ryukoku forest at Seta Hill in Shiga Prefecture. The decrease is due to not only the deposition onto leaf surfaces but also the effect of a tree wind break. We carried out wind tunnel experiment for the transport and dispersion in model trees and classified air purification in a woodland into the deposition of air pollutants and the effect of a tree wind break.
We found that the Rryukoku forest was a net sink of ozone. For fine particulate matter PM2.5, the chemical component data at the Seta Hill were compared with those in the nearby urban area. There was the difference due to the influence of local sources such as automobile exhaust gases.
