Abstract: | The airborne fungal spore types were studied in different libraries in Delhi, using an Andersen sampler and a Burkard personal
sampler, for culturable and non-culturable fungi respectively. The concentration inside the libraries, before and after the
agitation of books, were compared with outside air. The major contributors to the library air areCladosporium, aspergilli/penicillia, smuts andAlternaria, varying from 50 to 14%. Some fungi (Cladosporium, Alternaria, smut,Penicillium chrysogenum andnigricans) showed seasonal occurrence, corresponding to their occurrence in the extramural environment. Aspergilli/penicillia,Drechslera, Curvularia andAspergillus flavus had a significantly higher concentration (P<0.01) inside the library, and recorded a significant increase in concentration after agitation of books. Air-conditioned
libraries have low fungal spore concentrations, as compared to naturally ventilated libraries. |
