Airborne Fungal Spores
Fungal spores and especially mold spores are a normal component of the outdoor air. They are microscopic structures that function as “seeds” to allow fungi to reproduce. Apart from acting as “seeds” for reproduction, many fungal spores are adapted for dispersal and for survival, often for extended periods of time, in unfavorable conditions. Airborne Fungal […]
