Abstract

The purpose of the study was to characterize the microbiological quality of air in the St. Benedict
church in Cracow. The study was carried out during the spring season in 2016. Air samples were collected in triplicate at two points in the building (inside the church and the archaeological excavation) and at the one point outside the building. The air samples were collected using a 6-stage Andersen impactor. During sampling, the air temperature, relative humidity and dustiness were measured. The results showed that the bacterial aerosol concentrations in the measuring points ranged from 455 cfu·m-3 to 1185 cfu·m-3 and the fungal aerosol concentrations in the measuring points ranged from 124 cfu·m-3 to 500 cfu·m-3. The lowest concentrations of bacterial and fungal aerosol were observed in the outdoor air and the highest concentrations were observed in  archaeological excavation point. There were no significant differences in the bacterial and fungal aerosol concentrations between the measuring points (p>0.05). There was no correlation between the concentration of bacterial aerosol and temperature, relative humidity and dust in the air (p>0.05) and there was no correlation between the concentration of fungal aerosol and ralative humidity and dust (p>0.05). The analysis showed a significant correlation between the concentration of fungal aerosol and temperature (R=-0.84, p<0.05). Bioaerosol concentrations obtained in this study are lower than reference values for bacteria and fungi in residential and public buildings (5000 cfu/m3) recommended by the Panel of Experts of Biological Factors.
