Measurement of indoor viable airborne bacteria with different bioaerosol samplers

A study was carried out to assess, in a quantitative way, the coherence and variability of measurement results of viable airborne bacteria collected from different bioaerosol samplers. First, measurements were performed in a large unoccupied university amphitheatre, where air quality was supposed to be stable. Following this, measurements were performed in a small occupied lecture room, where large concentration variations were expected. Overall, the bioaerosol samplers provided coherent results.
