在马来西亚，地毯通常被用作清真寺主祈祷厅的地板装饰材料。在清洁地毯时，用吸尘器吸是最流行的方法，但它直接导致可能含有细菌和真菌的灰尘上升。吸尘活动和通风策略(空调分裂单元(ACSUs)或主动通风(非ACSUs))可以影响细菌和真菌的生长。本研究旨在建立不同通风策略(ACSUs和非ACSUs)下清真寺主祈祷大厅的细菌总数、真菌总数和PM₁₀浓度。在本研究中还进行了细菌和真菌种类的鉴定。在马来西亚Pulau Pinang的25座清真寺建筑(17座acsu和8座non- acsu)进行取样，在 zohora - asar 和周五- asar 祈祷场所铺设地毯。结果显示,总细菌数,总真菌数和平均点10 <子> < /子>在清真寺ACSUs浓度高于在清真寺non-ACSUs浓度从166 cfu / m <一口> 3 < /一口> 660 cfu / m <一口> 3 < / >一同晚餐,从118 cfu / m <一口> 3 < /一口> 660 cfu / m <一口> 3 < / >共舞,和从11.15 ±3 to 49.30 ±13.13和微观;g / m <一口> 3 < / >一同晚餐,分别。细菌总数超过了《室内空气质量工业操作规范》(ICOP)的可接受指导限值，但真菌总数和PM₁₀ 浓度没有超过。 In some mosques, the total bacterial and fungal counts did not decrease even after hoovering activities were completed. The dominant types of bacteria found in the mosque buildings were Staphylococcus spp., Bacillus spp. and Micrococci spp., whilst the dominant fungal species was Aspergillus niger. Although the findings were not alarming, care should be taken by mosques authorities especially while and after hoovering, to ensure that, the indoor air quality in mosques are being maintained within the permissible limit to protect worshippers from being exposed to bacterial and fungal.
