摘　　要：为了解安顺市酒店(宾馆)中苯系物污染现状及主要来源,规范酒店(宾馆)中苯系物含量标准和制定防控措施提供数据与基础,该文随机抽取安顺市24家不同级别的酒店(宾馆)作为监测对象,根据GB/T 18883—2022《室内空气质量标准》来确定采集点的要求,使用PID-Analyzer Mobile便携式GC-PID分析仪对各样本进行检测;定量资料使用中位数与四分位数间距进行统计描述;计数资料组间比较采用卡方分析检验。室内苯系物检出率分别为苯11.11%、甲苯13.89%、二甲苯未检出;对于检出苯系物的7个样本进行分析,42.86%的样本苯来源于室内,28.57%的样本甲苯来源于室内,14.29%的样本二甲苯来源于室外。当前安顺市酒店(宾馆)苯系物污染程度较轻,检测结果合格率较高;苯与甲苯主要来源于室内,二甲苯主要来源于室外。In order to understand the current situation and main sources of benzene series pollution in hotels(hotels)in Anshun City,standardize benzene series content standards in hotels(hotels)and provide data and basis for formulating prevention and control measures,this paper randomly selected 24 hotels(hotels)of different levels in Anshun City as monitoring objects,determined the requirements of collection points according to GB/T 18883—2022"Indoor Air Quality Standards",and used PID-Analyzer Mobile portable GC-PID analyzer to detect each sample;Quantitative data were statistically described using median and interquartile range;chi-square analysis was used to compare numerical data between groups.The detection rates of benzene derivatives in the room were 11.11%,toluene 13.89%,and xylene was not detected respectively;for the analysis of the 7 samples with benzene derivatives detected,42.86%of the sample benzene came from indoor,28.57%of the sample toluene came from indoor,and 14.29%of the sample xylene came from outdoor.Conclusion The current level of benzene contamination in hotels(hostels)in Anshun City is relatively light,and the pass rate of test results is high;benzene and toluene mainly come from indoors,and xylene mainly comes from outdoors.
