HRT was divided into five major compartments: (1) the nasal passage (ET1); (2) the pharynx (ET2); (3) the bronchial region (BB); (4) the bronchiolar region (bb); and (5) the alveolar-interstitial region (AI). Transport mechanisms of airborne PM in HRT include respiration, gravitational settling, turbulent diffusive deposition, inertial impaction, interception deposition loss, and PM clearance. We hope to estimate airborne PM mass lung/indoor ratios in the bronchial region, the bronchiolar region, and the alveolar-interstitial region, deposition fraction and exposure dose in the size ranges 0.01–10 µm via nosal or oral breathing in the near future.application/pdf76003 bytesapplication/pdfzh-TW國立臺灣大學生物環境系統工程學系暨研究所顆粒物質區塊模式肺部顆粒濃度/室內顆粒濃度比值Particulate matterCompartmental modelLung/Indoor ratioreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/10789/1/932313B002030.pdf
