【摘要】 采用沉降平板法调查了某大学１２６间学生宿舍空气中细菌污染状况，分析造成污染的可能因素。结果表明：空气中细菌总数＞１５０ＣＦＵ／９０ｍｍ平皿者达１９．０５％，室内不同感官卫生状况、不同楼层、不同时间采样以及不同性别寝室空气中细菌污染程度均有非常显著的差异（Ｐ＜０．０１），不同朝向寝室空气中细菌数超标率无显著性差异（Ｐ＞０．０５）。影响宿舍空气中细菌污染程度的主要因素与室内卫生状况、通风、采光以及人员活动情况有关，而与寝室朝向无关。更多还原

【Abstract】 We investigated the condition of bacterial pollution in the air in 126 dormitories of a university by using fallen plate method in May. 1993 and analysed the factors that might cause pollution.The results showed that the total rate of bacterial pollution above 150 CFU /agar plate in the air was l9. 05%(24/126).The difference was very significant among the degrees of bacterial pollution in the indoor air of the different sensation health condition,the different floors.the collecting samples at different time and between male and female dormitories(P<0.01).There was no difference of the bacterial pollution in the air between different direction of dormitories(P>0.05).The major factors influencing the bacterial pollution in the air of dormitoriers were its health condition, the ventilation,the lightnees and the people’s active condition.更多还原
