BIOAEROSOL IN INDOOR ENVIRONMENTS FOR CONSERVATION OF CULTURAL HERITAGE: POTENTIAL RISKS FOR HISTORICAL-ARTISTIC MANIFACTS ANO HUMAN HEALTH

An integrated approach was applied for the characterization of the biological airborne particulate in four Sicilian sites with peculiar structure, thermo-hygrometric and lighting parameters. We focalized the attention on: ,) Crypt in the Cathedral Treasury Museum (Palermo), an underground environment (lithic and stone artifact), daily visited by tourist and characterized by a reduced indoor-outdoor exchange; it) the Saints Cave in Licodia Eubea (Catania), a semi-confined environment (fresco), strongly influenced by the surrounding countryside and by a continuous airflow; iit) the Diocesan Historic Archive in Palermo, (documentary funds, IX-XXsec.), characterized by low air change rate and r…
