Airborne small allergen-carrying particles

Pollen fragments
Starch granules (released into the atmosphere under wet conditions and responsible for bronchial asthma outbreaks, thunderstorm associated)
Nonpollen plant parts (from inflorescences, leaves or Ubish bodies)
Nonplant particulate matter (allergens transferred through physical contact or by leaching from the surface of the pollen grain to other airborne small particles)
