Popis: 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 reduced frequency of fruitors; iv) the Sibilla Antrum (Trapani)a hypogeal environment (frescoes), where biological particulate can be vehicle by visitors and sometimes related to the presence of rodent pest. Non-invasive sampling was carried out on surfaces by Nylon membrane or by sterile swab. A portable sampler equipped with gelatin filters was utilized for aerosol. Microbial consortia colonizing both the works of art surfaces and the aerosol of conservation/exposure environments, were revealed and characterized by optical and electron microscopy (OM, SEM, CLSM), in vitro culture and molecular analysis.Combining biological results (Fig.1) with environment parameters data, acquired by HOBO U12 (temperature / relative humidity/ lighting) data-Ioggers (equipped with EEPROM memory), we define a protocol to prevent artifacts biodeterioration and to evaluate the potential health risk for visitors and operators, according to a preventive conservation strategy.
