| Outline of Final Research Achievements |
This study works on development, practical use of a small personal exposure measuring equipment and establishment of the new evaluation technique for the long-range transported pollution ratio based on the measurement.
(1) A new approach to evaluate transboundary PM pollution is applied to Tama-kyuryo, Kazo and Nagasaki city. The results suggest that transboundary pollution contributed more than 70% to the PM2.5 concentrations, and that the ontribution has a seasonal variation with a decrease in summer and an increase in autumn.
(2) The sensor system developed and used in the field test is a particle counter with a volume of 768 cm3, a weight of 420 g, and over 24 h of continuous operation. Using the sensor, personal exposure in winter were characterized for 5 subjects living in Sapporo area. Ambient PM2.5 data measured at fixed stations were used as a comparison against the personal PM2.5 exposures and produced poor correlations between personal and ambient PM2.5.

本研究は，センサー技術の進歩と情報ネットワーク網の整備を背景として，PM2.5汚染に対する健康影響評価と対策立案の構築を目指す大きな目的のもとにあり，(1)個人曝露量測定に対するセンサー手法の確立は世界の疫学研究やリスク軽減対策に貢献するものである。また，(2) 確立した越境汚染評価における新手法は，さまざまなリスク削減目標に対して国内対策がどの程度の有効になるかの推定を与えるものとして，汚染対策の立案に大きく寄与することが期待できる。
