某高校既有建筑室内人员相关VOCs目标污染物的实测分析

为研究高校既有建筑室内人群散发对室内VOCs的影响，对高校不同人群样本的教室及会议室两类典型人群密集房间，共82个人群样本对象进行了VOCs采样分析，得到不同实际场景下的人员相关的VOCs浓度水平，并对其潜在的影响因素进行分析。结果表明，共确认了29种与室内人员相关的高检出率且较高浓度值的物质，包括芳香族化合物9种，烷烯烃类9种，酮类和醛类8种，醇酯类以及卤化物3种，并得到主要VOCs物质的浓度水平和I/O比。对影响因素的统计分析表明，室内人员密度、季节和房间类型对不同VOCs物质存在显著性影响，其中季节性因素对目标VOCs污染物影响最为广泛，其次是房间类型与室内人员密度。该研究可为进一步了解人员密集室内VOCs污染现状及控制策略提供一定的科学参考。

Field investigation on human related VOCs in existing buildings in one university

In order to study the influence of occupants on the indoor VOCs in universities, we conducted VOCs sampling campaign in 82 densely occupied classrooms and conference rooms in one university. The VOCs concentration levels and influencing factors were analyzed. The results showed that 29 human related VOCs species with high detection rate and higher concentration values were confirmed, including 9 kinds of aromatic compounds, 9 kinds of alkanes, 8 kinds of ketones and aldehydes and 3 kinds of alcohol esters and halides, and the concentration levels and I/O ratios of the main VOCs substances were obtained. Statistical analysis of the influencing factors showed that indoor occupancy rate, season and room type have significant effects on different VOCs species, in which seasonal factors have the highest degree of influence on target VOCs pollutants, followed by room type and indoor occupancy rate. This research can provide a scientific reference for further understanding of indoor VOCs pollution and control strategies in densely occupied buildings.
