Abstract

Conservators and curators pay much attention to the variability of microclimate conditions, contaminations, air pollution, and the influence of visitors on the damage of museums since atmospheric and gaseous pollutants could affect the conservation of cultural heritage. This work has regarded the monitoring of indoor air quality to evaluate the effects of environmental pollution in the field of cultural heritage. In particular, two different archaeological places were analysed: Fruscione Palace and S. Pietro a Corte in Salerno, Italy. The work focused on the influence of tourists on environmental pollution correlated to indoor air quality during many social and cultural events. Moreover, it was also analysed the possible use of the carbon isotope composition of CO₂ as a tool for environmental studies in the field of cultural heritage. The results showed a good correlation between the isotopic composition of CO₂ and the variation of pollutants concentration in the air, demonstrating that it is a valid tool and non-invasive marker to monitor environmental pollution of museums and cultural heritage.
