ABSTRACT
Aerobiology involves the study of airborne bioparticles, that is, particles of biological origin. Subsequent to the 1930s, aerobiology was classified basically into indoor aerobiology and outdoor aerobiology. Some aerobiologists preferred to segregate the study of airborne pollen into a sub branch of aerobiology termed as ‘aeropalynology’. Aerobiology involves study of airborne particles of plant and animal origin. These bioparticles get into the atmosphere after their release from the source. The primary objective of aerobiological studies is to monitor, determine and detect the occurrence of pollen and spores and their relative representation in the atmosphere. The aerobiological pathway involves at least five major steps, which are: source, liberation, passive transport, deposition and impact on vegetation, water bodies and various substrates. Pollen constitutes a small part of the aeroplankton or air-spora present in the atmosphere. The most frequent particles of biological origin are microorganisms, especially the spores of fungi.
