Determination of Bacterial Bioaerosol Concentration in Indoor Air of Ardabil Universities in 2020

The purpose of this study was to investigate the exposure of individuals to bacterial bioaerosols in indoor air and to investigate the factors affecting their concentration in Ardabil city. In this study, 12 Sports halls (including futsal, volleyball, and bodybuilding halls) were selected and the samples of bacterial bioaerosols were taken from their indoor air.

Air sampling was performed using Anderson's single-stage sampler with a discharge rate of 28.3 liters per minute and a respiratory range of 10 minutes.

The results showed that the mean concentration of bacteria in all gyms was 494.24 CFU/m3. The concentration of bacteria in the gyms of Mohaghegh Ardabili, Medical Sciences, Islamic Azad and Payam Noor were 203.5, 728.5, 504.6 and 576 CFU/m3, respectively. The average bacterial concentration in the air was 60.5 CFU/m3. The dominant species of bacteria in indoor air were Staphylococcus aureus, Staphylococcus epidermidis and Bacillus, respectively.

According to the results of this study, it is found that the concentration of bacterial bioaerosols is high in indoor air of sports halls and these halls can be considered as a potential hazard and cause respiratory diseases in athletes who use these halls.
