【摘要】 目的 了解宾馆开业时室内空气质量及对从业人员健康的影响。方法 选择4家2～4星级新建并已装修的宾馆于开业后1～4周进行室内空气质量卫生学调查,同时进行从业人员健康影响调查。结果 宾馆内温度、相对湿度、CO、CO2和空气细菌总数与室外对照差异无显著性。甲醛和可吸入颗粒物与室外对照差异有显著性（P<0.05）,其中客房内分别高达（0.42±0.23）mg/m3和（0.13± 0.08）mg/m3。从业人员眼、鼻和咽刺激症状、失眠、头晕和头痛症状阳性率均高于开业5年以上宾馆内从业人员,其中咽、眼刺激症状阳性率高达70.0％和50.0％。结论 新开业宾馆甲醛污染主要来自装饰材料及室内通风换气不足。更多还原

【Abstract】 ve To understand the indoor air quality of hotels after the openning for business and its health impacts on employees. Methods The hygienic investigation on indoor air quality was carried out in 4 newly built and decorated 2~4-star-grade hotels during the 1st week to the 4th week after openning for businesses well as the health impacts on employees. Results The levels of room temperature, relative humidity, carbon monoxide, carbon dioxide and total count of bacteria in indoor air of hotels showed no significant differences, but the concentrations of formaldehyde(HCHO) and inhalable paniculate (IP) of hotels showed significant differences compared with those of outdoor control(P<0.05) . The concentrations of HCHO and IP in indoor air highly reached (0.42 ?0.23)mg/m3 and (0.13 +0.08) mg/m3 respectively. The percentage of irritation symptoms of eyes, mucous membrane and throat, in-somnia, dizziness and headache, especially the prevalance rates of eyes irritation (70.0% ) and throat irritation (50.0%), among employees in 4 newly decorated hotels showed higher levels compared with those of control hotels openning for business for more than 5 years. Conclusion The indoor air pollution by HCHO mainly caused by deco-ration materials and insufficient ventilation in indoor air of hotels newly openned for business.更多还原
