STUDY OF INTOLERABLE AIR POLLENS AND HYPERSENSITIVITY FROM SELECTED AREAS IN DELHI NC

Abstract

People routinely exposed to the heavy traffic suffer from respiratory diseases like asthma, acute
bronchitis due to presence of bacteria, fungi, and organic dusts in the air. Life at these areas
studied became a health hazard. A survey of aerospora conducted in five selected areas of Delhi
NCR showed that bacteria and fungi were present in the order of 3x103
and 2x103
respectively.
21 fungal species and 7 bacterial species were present in the present study. Many filamentous
fungi known to be aeroallergens were present, Aspergillus being the predominant species.
Pathogenic bacteria like Pseudomonas, Staphylococcus were present in many areas of study. The
threshold limit value (TLV) and Biological exposure indices values should be liaised for every
area in the city which will serve as guide to control health hazards.
