Atmospheric pollen and mold spores in Bangkok: a 15 year survey.

A 15-year survey of atmospheric pollen and mold spores was carried out in Bangkok, Thailand, from January 1973 to December 1987 by Durham's standard gravity slide sampler. The pollen and mold spore counts were presented. The peak of the pollen and mold spores occurred during the time of the year with lower average temperature, relative humidity and rain-fall. For pollen, this was from November to January and for mold spores from December to February. Mold spores of the Class Fungi Imperfecti were predominant and most likely the major fungi in mold allergy. Grass was the principal air-borne pollen.
