Abstract

Bioaerosols were evaluated in different places at the faculty and in the health centre. Mas-100 Air Sampler was used for bioaerosol collection. Average bacterial and fungal concentrations at the faculty were 423±842 cfu/m³ and 142±374 cfu/m³, respectively. These data together with data of moulds identification indicated that only 2 indoor environments among 26 examined places at the faculty contained unacceptable bioaerosols. Statistically significant correlation was found between the bacterial concentrations and the numbers of present persons. Average bacterial and fungal concentrations in the health centre were 405±206 cfu/m³ and 73±56 cfu/m³, respectively. Bioaerosols concentrations in the health centre with HVAC system statistically did not differ from the ones obtained at the faculty. As only limited numbers of bioaerosols were examined in the health centre further investigations are necessary to evaluate efficiency of HVAC system.
