Circadian and seasonal periodicities of some mold allergens in the atmosphere of Madras city (India)

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Circadian and seasonal periodicities of 10 fungal spore types common in the atmosphere of Madras city are described from data obtained by sampling air with a Burkard model of the Hirst spore trap for a period of one year. The periodicity ofNigrospora conformed to ‘post-dawn pattern’;Alternaria, Drechslera, Curvularia, Torula to ‘mid-day pattern’;Cladosporium andPericonia to ‘double peak pattern’;Ganoderma, Coprinus andLeptosphaeria to ‘night pattern’. Maximum incidence of the spores were noticed in the atmosphere during August to December corresponding with the rainy season.
