【摘要】 目的了解星级宾馆室内颗粒物污染水平,室内其他污染物及微小气候状况,分析室内颗粒物浓度的影响因素。方法选择星级宾馆6家,春、夏、秋、冬4个季节分别进行1次采样,监测室内污染物浓度(CO、CO2、PM10、PM2.5)、室内微小气候(温度、湿度、风速)及室外污染物浓度(CO、CO2、PM10、PM2.5)。结果室外颗粒物PM10、PM2.5浓度高于室内,差异有统计学意义(P<0.05)。室内颗粒物PM2.5占PM10的比例高于室外,差异有统计学意义(P<0.05)。室内PM10与PM2.5之间、室内PM10与室外PM10之间、室内PM2.5与室外PM2.5之间,存在相关性。室内PM10、PM2.5浓度与室内CO浓度存在相关性。室内PM10、PM2.5浓度与室内CO2浓度不存在相关性。室内PM10、PM2.5浓度与室内湿度存在相关性。结论星级宾馆室内颗粒物浓度较低,室内空气质量较好。室内PM10、PM2.5浓度随室内湿度增大而增大。更多还原

【Abstract】 Objective The aim of this study was to know about the pollution level of particulate matter(PM10, PM2.5) and other indoor air pollutant(CO, CO2) in star-rated hotels, in order to investigate the influencing factors of the particulate matter. Methods Six star-rated hotels in Xicheng district of Beijing were chosen in this study. Indoor and outdoor pollutions(CO, CO2, PM10, PM2.5) was monitored in four different seasons. At the same time the indoor microclimate was also monitored. Results The outdoor average concentrations of PM10 and PM2.5was higher than indoor, respectively. The indoor ratio of PM2.5in PM10 was higher than that outdoor,respectively. There was a correlation between PM10 concentration and PM2.5concentration. There was a correlation between particle concentration indoor and outdoor. There was a correlation between particle concentration and CO concentration. There was a correlation between particle concentration and humidity. Conclusion The air quality of star-rated hotel room is good. The particle concentration varies with humidity.更多还原
