本研究的目的是表征法国教室室内空气质量（IAQ）和通风之间的关系。在一个学习周内测量了17所学校51个教室的各种参数，包括挥发性有机化合物、醛类物质、颗粒物（PM2.5质量浓度和数量浓度）、二氧化碳（CO2）、气温和相对湿度。通风的几个指标，如空气交换率、通风率（VR）和空气闷度指数（ICONE），与室内CO2浓度有关。研究了季节（采暖或不采暖）、学校类型（幼儿园或小学）和通风对室内空气质量的影响。根据法国立法对机械通风教室的最低要求4.2 l/s /人，91%的教室通风不足。机械通风教室的VR明显高于自然通风教室。室内空气质量和通风之间的相关性取决于每种污染物主要来源的位置（室外还是室内），对于室内污染源，取决于它是否与居住者的活动或持续排放有关。
The aim of this study was to characterize the relationship between Indoor Air Quality ( IAQ) and ventilation in French classrooms. Various parameters were measured over one school week, including volatile organic compounds, aldehydes, particulate matter ( PM2.5 mass concentration and number concentration), carbon dioxide ( CO2), air temperature, and relative humidity in 51 classrooms at 17 schools. The ventilation was characterized by several indicators, such as the air exchange rate, ventilation rate ( VR), and air stuffiness index ( ICONE), that are linked to indoor CO2 concentration. The influences of the season ( heating or non-heating), type of school ( nursery or elementary), and ventilation on the IAQ were studied. Based on the minimum value of 4.2 l/s per person required by the French legislation for mechanically ventilated classrooms, 91% of the classrooms had insufficient ventilation. The VR was significantly higher in mechanically ventilated classrooms compared with naturally ventilated rooms. The correlations between IAQ and ventilation vary according to the location of the primary source of each pollutant ( outdoor vs. indoor), and for an indoor source, whether it is associated with occupant activity or continuous emission.
