Preliminary testing of a new bioaerosol sampler developed for the measurements of low and medium concentration levels of airborne bacteria and fungi

A new bioaerosol sampler developed for extremely low concentration levels of airborne bacteria and fungi has been described. The results of the pilot study of the prototype of this new sampler are also presented in this paper. During the field studies the concentration levels of bacterial and fungal aerosols were obtained using simultaneously the new sampler and the reference cascade Andersen 6-stage impactor, as well as the Air Ideal sampler. Although only a preliminary study has been carried out, the obtained data indicated that the assumed designing parameters for the new sampler are suitable and guarantee high collection efficiency of this instrument.
