Airborne fungi, termed fungal bioaerosols, have received attention due to their association with public health problems. The search for ways to prevent the harmful effects of fungal bioaerosols has created a high demand for research and development of efficient methods for controlling bioaerosols. We investigated variations in aerosol characteristics including total number concentration, size distribution, and surface morphology of fungal bioaerosols under a thermal heating process, a promising bioaerosol control method, in a continuous-flow system. Quantitative thermal characteristics of fungal bioaerosols were also obtained from thermogravimetric analysis. Our experimental results show that the aerodynamic and physical diameter of tested fungal bioaerosols decreased when exposed to increasing surrounding temperatures, even within a short exposure time of about 0.15 s. The instantaneous exposure to high temperature significantly changed the surface morphology of the fungal...
