摘要
目的 :调查银川市室内娱乐场所空气中微生物的污染状况。方法 :随机选择四家歌舞厅和四家旱冰场 ,每个场所内设五个点 ,分别于未放客、放客中和放客高峰三个时间段 ,用暴露法进行空气样品的采集。结果 :未放客前细菌总数 (BT)、溶血性链球菌 (HS)分别超出标准 1 5倍、2 4倍。至放客高峰时 ,BT、HS显著高于未放客和放客中 (P <0 0 1 )。儿童娱乐场所中的HS和真菌在不同时间段均显著高于成年人娱乐场所 (P <0 0 1 )。放客高峰时 ,成年人娱乐场所中的BT量显著高于儿童娱乐场所 (P <0 0 1 )。结论 :室内娱乐场所中微生物浓度和数量随着人数的增加而增加。人均容积影响室内污染物的累计量。
Objective:To investigate the bacterial contamination of indoor air at entertainment places in Yinchuan.Methods:4 dancing and singing halls and 4 dry-skating halls were randomly chosen and were set up 5 sampling points at every place.With exposure method,the air samples were collected respectively before opening,during service and at the peak hours of players attending.Results:The result showed that before opening the total number of becteria (BT) and hemolytic streptococcus(HS) were 1.5 times and 2.4 times over the allowance for adult and child respectively.At the peak hours of players attending,the BT and HS reached its peak(P<0.01).The numbers of HS and fungus at the entertainment place for children were markedly higher than that of the entertainment places for adult(P<0.01). At peak hours the BT at the entertainment for adult was higher than that of the entertainments for child(P<0.01).Conclusion:The concentration and kind of microorganism were increased along with the increase of players at service hour each day.The accumulation of indoor pollution was influenced by the average volume per person.
