Bioaerosols as part of the "sick building syndrome" and "building related illness": 2 case studies
Sick Building Syndrome (SBS) and Building Related Illness (BRI) are major concerns when considering the health of building occupants. SBS is defined by unspecific signs and symptoms that building occupants experience when they expose to combination of chemical, physical and biological factors (bioaerosols), whereas BRI is used to describe clinically identifiable illnesses due to specific airborne microorganisms. Because of this, the incorporation of biocides in construction materials is becoming more relevant. In this study we determined the type and density of airborne bacteria and fungi (bioaerosols) in two environments: surgery rooms and intensive care units from a public hospital (30 white areas) and office rooms from an electric company headquarter (27 non-white areas). Air samples were taken by the impaction method using a MAS-100 air sampler. Results showed that bacterial and fungal densities in the white areas ranged from 14 UFC/m3 to 204 UFC/m3 and from 2 UFC/m3 to 204 UFC/m3, respectively, whereas the results from the non-white areas depicted bacterial and fungal densities from 56 UFC/m3 to 347 UFC/m3 and from 6 UFC/m3 to 800 UFC/m3, respectively. According to the air microbial quality index used in this study 2 surgery rooms and 14 offices were found to be contaminated. Some bacterial pathogens were found in both buildings, whereas no pathogenic fungi were isolated.
