Abstract

In museums, libraries and archives, paper heritage (books, prints, drawings, photographs) are sources for growth and dispersal of bioaerosol, especially fungi. Airborne biological spores are potential biodeteriogens and play an essential role in the processes of biodeterioration; once deposited on the surface of artwork, may accumulate in the dust and whether there are favorable microclimatic conditions, they develop and can cause serious damage. The present article discusses the proposal of an integrated system of biological and microclimatic monitoring which represents the first step to estimate the biological risk for paper heritage. It is based on a methodological model for the analysis of: 1) airborne microorganisms with active and passive methods; 2) microbiological sampling of surface of artwork with non-destructive techniques based on nitrocellulose membrane; 3) air fungal spores with a spore trap (Hirst type) and microscope; 4) surface and airborne allergens with immunoenzymatic assays; 5) airborne particles with a laser particle counter; 6) microclimatic monitoring with multi data-logger for continuous measurements of: air temperature, relative humidity, air velocity, air radiant temperature; 7) transient simulations for indoor climate and air quality investigation with the application of Computational Fluid Dynamics (CFD).
