Potential harm of fungal aerosol in scientific research environment

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.
