摘要

本研究旨在調查台灣地區托兒所室內空氣污染物濃度並推斷其決定因素。除了在不同通風條件下進行空氣品質現場量測，並收集室內空氣品質相關環境變數，再依序透過單變量統計分析及多元回歸分析從10項環境變數中篩選出室內空氣品質決定因素。比較不同通風條件之室內空氣品質後發現，相較於使用空調條件，自然通風條件之室內CO及PM10濃度較高，決定因素爲室外濃度、區位屬性及廚房毗鄰程度。相較於自然通風條件，使用空調條件之室內CO2及HCHO濃度較高，決定因素爲室外濃度、窗簾裝設、換氣率、地板清潔頻率及人員密度。日後托兒所孩童流行病學研究，應將上述決定因素視爲暴露危害分級之代表性指標。

This study aims to investigate indoor pollutants concentrations in Taiwan child care centers (CCCs) and evaluates their determinants. Measurements were performed in different ventilation conditions while information on CCCs characteristics was collected. Determinants of indoor pollutant levels were evaluated with univariate analyses and regression analyses. The results showed indoor CO and PM10 concentration levels were higher in naturally ventilated (NV) than air-conditioned (AC) CCCs and determinants of indoor pollutant levels in NV CCCs were outdoor concentration, location and proximity to kitchens. Besides, indoor CD2 and HCHO concentration levels were higher in AC than NV CCCs and determinants of indoor pollutant levels in AC CCCs were outdoor concentration, presence of curtains, air exchange rates, floor cleaning and occupant density. Future epidemiological analyses in CCCa should consider these determinants in classifying exposures as surrogate indicators of sources.
