Abstract:
Test particles for the calibration and evaluation of aerosol samplers are usually dispersed by conventional aerosol generation methods. These techniques lead to the formation and aerosolization of microbial fragments which affect the deagglomeration of the bacteria or fungal spores thereby decreasing the number of test particles. The newly developed aerosol generation method reduced microbial stress and minimized the number of aerosolized droplets which return to the liquid pool allowing test particles optimization while the new spore generation system produced non-aggregated fungal spore aerosol directly from a moldy surface which makes it suitable for laboratory bioaerosol studies.
