Abstract

For the purpose of this paper, the actual air temperature and air humidity values were monitored in the Visitor Centre of the Archaeological site 1a Imperial Palace Sirmium, designated cultural heritage of exceptional importance. The contamination level of archaeological finds in the site was microbiologically analysed. The findings showed that during the phase of microclimatic monitoring (February–April 2021), air humidity was almost constantly above the levels set by standards and recommendations for museum collections (>60%). The highest levels of air humidity, amounting to 93%, were recorded in February, with daily oscillations of up to 30%; the lowest recorded temperature was 0.3°C, with the maximum daily oscillations of 6°C. Microbiological analysis revealed great diversity in the deterioration level of the finds, which can be attributed to the time lapse between the last conservation and the present. The comparative analysis of microclimatic monitoring and microbiological analysis results identified high levels of relative air humidity as the dominant factor in the increased microbiological contamination of the finds. The findings also pointed to the necessity of continuous microclimatic monitoring during the actual usage of the facility in order to provide the sustainable display and preservation of the finds on the premises.
