1. Introduction and History of Aerobiology
- Core Concepts: Definitions of aerobiology, extramural (outdoor), and intramural (indoor) environments.
- Historical Aspects: Evolution of the science from Louis Pasteur’s “floating germs” up to the founding of the International Association for Aerobiology (IAA).
2. Biological Particulates in the Air (Airspora)
- Pollen: Identification, structure, and seasonal distribution of pollen grains.
- Fungi and Spores: Morphological features of airborne fungal spores and their environmental significance.
- Microorganisms: Presence and distribution of airborne bacteria, viruses, and microbial bioaerosols.
3. Mechanisms of Liberation and Dispersion
- Take-off: Active and passive mechanisms of spore and pollen discharge.
- Dispersal: Horizontal and vertical transport patterns dictated by wind, rain, and humidity.
- Deposition: Mechanics of sedimentation, impaction, and rain wash-out.
4. Aerobiological Sampling Methods and Instrumentation
- Volumetric Samplers: Operational principles of Hirst, Burkard, and Anderson samplers.
- Passive Sampling: Sedimentation slides, gravity petri plates, and older sampling methods.
- Analysis: Microscopic quantification and recording techniques for tracking daily or seasonal concentrations.
5. Applied Aerobiology
- Agricultural Aerobiology: Epidemiology of airborne plant pathogens, crop disease forecasting, and outbreak management.
- Medical Aerobiology: Identification of airborne allergens causing asthma, hay fever, and respiratory diseases; clinical aspects of allergy-causing pollen and fungal strains.
- Indoor Aerobiology: Bioaerosols in homes, hospitals, and storage facilities; issues related to indoor mold contamination.
