Peculiarities of Registration of Fungi Spores in the Air with the Help of Aerosol Particles Counters

Abstract

The applicability of laser aerosol particle counters for the registration of microscopic fungal spores in the airborne state (including in the presence of background concentrations of atmospheric airborne particles) was demonstrated during the experiments, and a technique was developed to transfer large (from one to several tens of microns in diameter) fungal spores to the air-suspended state, and to register them confidently with a resolution ensuring their identification. Despite the relatively large size of spores, their detection by the aerosol particle counter is possible for a period of time sufficient to track the movement of spores over significant (compared to conventional dust particles) distances. At the same time, according to the results of measurements, it is possible to judge not only the presence of spores in the air, their size, quantity and ways of movement, but also to draw some preliminary conclusions about their properties, in particular, about the tendency to glue and form aggregates. fungal spores, aerosol, particle size distribution, aerosol particle counter.
