Abstract

The microbial load in the air of confined areas can be a risk of contamination to objects and workers.  In this work, along with the usual parameters registered, such as relative humidity and temperature, the environmental fungal load in different storage units of the National Archive (Chile) was also included.  Using a microbial airsampler MAS-100 Eco®, the cultivable fungal fraction was determined in two intensive samplings (winter/spring).  Higher fungal concentrations were observed in spring in relation to winter, classified into low, medium, and high levels, according to the standards set by the Commission of the European Communities (CEC 1993).  In addition, fungal genera usually documented in museums, exhibitions, and storage rooms, which might be pathogenic to humans, were identified.
