Cultural heritage safeguard through multi-parameter air quality monitoring
Artworks restoration and conservation awareness has risen in the last years. In this regard, it is important to carry out an air quality study to identify and quantify air pollutants that threaten works of art. In this study the results of a air quality monitoring campaign carried out at the Beata Vergine dei miracoli Sanctuary, in Saronno (VA, Lombardy Region, Northern Italy), during summer 2022, are presented. A multi-parameter monitoring system able to measure at the same time CO2, NO2, O3 and PM10 was employed. A comparison with outdoor values for the same pollutants was performed with the purpose to understand how outdoor pollutants affect indoor air quality in the Sanctuary. This work is crucial in developing microclimatic conditions and air quality control strategies, to assure that the marvellous works of arts stored in the church will continue to inspire people for the times to come.
