[目的]了解南宁市城区旅店客房的空气质量,探讨影响空气细菌总数的有关因素,为提高旅店客房空气质量提供参考依据。[方法]2007年7~12月,在南宁市城区选择中小型旅店85家,对242间客房进行检测。[结果]检测242间客房,细菌总数2~178个/皿,中位数为59.31个/皿,合格的62间,合格率为25.62%。细菌总数合格率,7~8月、9~10月、11~12月分别为34.78%、15.93%、32.43%(P<0.01或P<0.05),相对湿度50%~69%、70%以上的分别为16.67%、25.73%(P>0.05),有空调的、无空调的分别为26.44%、17.11%(P>0.05),可吸入尘含量<0.05mg/m3的和≥0.05 mg/m3的分别为28.02%、11.84%(P<0.05)。[结论]南宁市城区部分旅店客房空气质量较好,空气细菌总数合格率受到季节和可吸入尘含量的影响。
[Objective] To understand the air quality of hotel rooms in urban area of Nanning, discuss the relevant factors that affect the total number of airborne bacteria and provide reference for improving the air quality of hotel rooms. [Method] From July to December 2007, 85 small and medium-sized hotels were selected in downtown Nanning and 242 guest rooms were tested. [Results] The total number of bacteria was 2 ~ 178 / dish in 242 rooms, with a median of 59.31 / dish and 62 qualified ones with a pass rate of 25.62%. The passing rate of total bacteria was 34.78%, 15.93%, 32.43% (P <0.01 or P <0.05) from July to August, from September to October and from November to December respectively, with the relative humidity of 50% -69% and over 70% (16.67%, 25.73%, respectively) (P> 0.05), 26.44% and 17.11% respectively with air conditioning and without air conditioning, and those with inhalable dust content <0.05mg / m3 and ≥0.05 mg / m3 Of them were 28.02% and 11.84% respectively (P <0.05). [Conclusion] The air quality of some hotel rooms in urban area of Nanning City is good, and the passing rate of the total number of airborne bacteria is affected by the season and the inhalable dust content.
