| Outline of Final Research Achievements |
Roof dust and rood dust were collected from 34 airports in Japan and their harmful element concentrations were determined. As a result, the concentrations and number of departure and landing (operation density) of the each airport were positively and significantly correlated. Element concentrations in the roof dust collected from airports were higher than those from non-airport building and the difference was larger in the main airports than local ones. The higher element concentrations were observed in roof dust than road dust and they showed different lead isotopic ratio. Roof dust on the airport building, road dust beside street and sediment sample along railway exhibited different harmful element concentrations and composition thus indicated different pollution situation as a response of different transportation mode. As a conclusion, this study made it clear that airplane operation is a remarkable emission source of harmful elements to the environment.
