bioaerosoler
Bioaerosoler, or bioaerosols, are airborne particles of biological origin that may include viable microorganisms or non-viable components such as fragments, toxins, or pollen. They originate from soil, water, plants, animals, humans, and built environments, and can be released during coughing, speaking, cleaning, showering, or from damp materials. Sizes range from about 0.01 to more than 100 micrometers; smaller particles can reach the lower respiratory tract and travel with air currents.
Health effects vary by constituent and host factors. Exposure can cause allergic reactions, airway irritation, asthma,
Measurement uses air sampling with filters, impactors, or liquid collectors, followed by culture, microscopy, or molecular
Control measures emphasize ventilation, filtration (e.g., HEPA), humidity control, source management, and regular cleaning to limit
