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。
Objective To understand the indoor air quality and the health effects of employees when the hotel is opened. Methods Four 4 ~ 4 star newly built and renovated guesthouses were surveyed for indoor air quality hygiene 1 ~ 4 weeks after the operation, meanwhile, the survey on health effects of practitioners was conducted. Results There was no significant difference between the indoor temperature, relative humidity, CO, CO2 and air bacteria and the outdoor control. There was a significant difference (P <0.05) between formaldehyde and respirable particulate matter and outdoor control, with room temperature up to (0.42 ± 0.23) mg / m3 and (0.13 ± 0.08) mg / m3 respectively. The positive rates of ocular, nasal and pharyngeal irritation symptoms, insomnia, dizziness and headache among practitioners were all higher than those employed in hotels for over 5 years. The positive rates of pharyngeal and ocular irritation were as high as 70.0% and 50.0% respectively. Conclusions Formaldehyde pollution in newly opened hotels mainly comes from decorative materials and lack of indoor ventilation.
