Microorganisms are ubiquitous in the built environment, posing threats to human health and building materials. Understanding of the factors that drive the composition of microorganisms in the built environment is nascent. The main objective of the present study was to evaluate bacterial and fungal contamination in the air state and those associated settled dust regarding concentration, size fraction and biodiversity at certain non-industrial (non-occupational) premises. The premises included: libraries, faculties, child day-care centers, schools and hospitals, differ in geographical location, age, size, design, ventilation type, number of occupants and activity. Airborne bacterial and fungal bioaerosols were collected using an Andersen two stage impactor sampler, it divides particles into fine (≤8 μm) and coarse (≥8 μm) size ranges.
