不同生物实验室气载真菌检测分析

Potential harm of fungal aerosol in scientific research environment

    摘要
  • 摘要: 目的 分析实验室真菌气溶胶分布特征,为生物实验室工作人员提供预警资料.方法 采用6级An-derson空气采样器,马铃薯葡萄糖琼脂(PDA)培养基分别在真菌实验室,普通实验室进行采样.结果 真菌实验室的优势菌株为黑曲霉、岛青霉和黄曲霉,分别高于平均浓度195,60和20 CFU/m3;普通实验室的优势菌株为青霉,含量高达67.4%.真菌实验室、普通实验室气溶胶浓度分别为813和304 CFU/m3,计数中值直径(count median dianeter,CMD)分别为2.76和3.66μm,粒子均可直接进入肺泡,而且能直接进入肺泡的真菌粒子浓度是普通实验室的3.1倍.结论 真菌实验室真菌浓度远高于普通实验室,已被真菌污染,而普通实验室真菌浓度较低,CMD值与居室接近,因此,拥有较好的空气质量.

     

    Abstract: Objective To detect fungal aerosol distribution in laboratory for biological laboratory safty.Methods Airborne fungal samples were collected by Ande rosn 6-stage,PDA mediun in the fungal laboratory and ordinary laboratory.Results The predominant fungi genera were A.niger,P.islandiun and A.flavus in the fungal laboratory and 195,60,and 20 CFU/m3 higher than that of in the average concen tration.The prdeominant fungi genera was Penicilliun auounting for 67.4% of fungi in ordinary laboratory.The concentrations of fungal acrosol were 8.3 CFU/m3,304 CFU/m3,and the CMD(count median dianeter)were 2.76,3.66μm in fungal and ordinary lobaratory,respectively.Conclusion The results showed that the content of fungi in fungal laboratory was much higher than that of ordinary laboratory.
