Outline of Research at the Start

大気汚染物質の曝露評価に必要とされる高空間解像度分布推定が可能であるLand Use Regressionモデルを構築する.また,詳細な気象場の取り込みや越境汚染の影響を考慮するための広域大気質モデルとのハイブリッド化を行うことにより,日本特有の大気環境の特性を考慮したモデルの開発と精度向上のための改良を行う.さらに,モデルの予測結果を既に実施された疫学調査に適用して健康影響評価を行うことで,LURモデルの有用性を確認する.

Outline of Final Research Achievements

We have developed and improved a statistical model called the Land Use Regression (LUR) model for improving the accuracy of air pollutant exposure estimation. In order to consider the effects of local meteorological factors and long-range transport of air pollutants, affecting the air pollution concentration in Japan. We constructed a hybrid model that incorporates the outputs of meteorological models and air quality models. We also introduced machine learning techniques in constructing the LUR models and assessed the effects of introducing the techniques. Moreover, in order to cooperate with the the epidemiological surveys that have already been conducted, we estimated the exposure concentration over 30 years from the time when PM2.5 monitoring was not carried out, and estimated PM2.5 components concentrations over 10 years in Japan.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は,都市域を中心として未解決の問題である大気汚染物質の曝露に伴う健康影響の評価における基礎情報としての曝露量推定手法の発展に貢献すると考えられる.今回開発したモデルを既に実施された疫学調査と連携させることにより,大気汚染と健康の影響の関連についてより高精度の分析が可能になる.
