title: Bioaerosols and office building ventilation systems.
abstract: Becterial and fungal spore samples were collected from twelve office building ventilation systems. Measurements were done both with and without humidification. Ventilation or humidification systems were not found to act as bioaerosol sources in any case. No difference was observed between bioaerosol counts in offices with and without humidification. The microbial levels decreased in all ventilation systems.
