Indoor biological contaminants and symptoms of sick building syndrome in office buildings in Mauritius

This study was carried out to investigate possible relationship between bio-contaminants and symptoms of sick building syndrome among office workers in Mauritius. Viable microbial colonies were collected using a Casella slit sampler in 23 selected indoor office buildings. A questionnaire survey as well as a walk through investigation was undertaken. Physico-chemical measurements were also monitored in the selected offices. Results of this study showed that number of indoor bacterial bioaerosol concentrations ranged between 3 and 1110 CFU/m(3) while fungal counts were 0-196 CFU/m(3). However, most of the buildings showed absence of dust mites. In conclusions fungal contamination was found to be associated with the onset of sick building syndrome symptoms among workers in office buildings in Mauritius.
