Protecting Art and People: Environmental Monitoring of Beata Vergine dei Miracoli Sanctuary for Health and Heritage Conservation

This research article discusses the importance of environmental monitoring to ensure the health and well-being of humans and ecosystems, with a specific focus on cultural heritage sites, which are susceptible to damage by pollution and microclimatic conditions. The Beata Vergine dei Miracoli sanctuary, a notable cultural heritage site in Italy, was studied to analyse the environmental quality of the site and any changes in environmental conditions during the COVID-19 pandemic. The study monitored different environmental parameters from 20 January to 11 April 2023. The data collected were evaluated, and the results were compared with previous campaigns. This study highlights the importance of environmental monitoring in cultural heritage site conservation, particularly in response to global challenges like climate change and pandemics.

Air quality assessment in cultural heritage: the case study of the Amalfi Cathedral (Amalfi, Salerno, Italy)

Air pollution is a serious problem for the preservation of cultural heritage. In fact, the iteration works of art with atmospheric pollutants leads to their degradation. To define the impact of air quality on artifacts, it is necessary to measure the pollutants levels through an air quality measurement system. In this study, the levels of particulate matter (PM10, PM2.5 and PM1) near the Amalfi Cathedral (Amalfi, Salerno, Italy) were measured by using the Sensy sensor. The analysis of the data recorded by the Sensy sensor was useful in identifying the air quality in an area that is very crowded with tourists from around the world. By analyzing the data collected by the sensor, researchers were able to assess the air quality in the area and evaluate the potential impact of air pollution on the cultural heritage sites in the region.

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.

Preliminary assessment of wave energy hazards in a shallow underwater water cultural heritage site

Coastal areas are characterized by high energetic conditions associated with the wave transformation processes and by numerous underwater cultural heritage (UCH) sites whose preservation is crucial given their cultural and economic value. Wave energy is considered a significant hazard driver for the conservation of UCH sites in wave-exposed coasts and may cause the scattering and scouring of archaeological objects, which results in the loss and degradation of the sites. In this paper, the wave energy-induced threats of a coastal site that was revealed due to coastal erosion in the mid-1970s and now is completely submerged in shallow waters, is examined. The results showed that wave energy is a significant threat due to the scouring and weathering phenomena that can detach materials from the structure.

Decay assessment approach of building stones from cultural heritage in freshwater reservoirs

Numerous cases of built cultural heritage that once were submerged in freshwater reservoirs are emerging in the last years due to increasing droughts. The DAMAGE project assesses the study of the specific degradation processes that occur in the building stones of this type of heritage subjected to constant immersion and emersion cycles. A real case of a Spanish old royal site, flooded in the 1950s, has been studied through portable non-destructive techniques to evaluate the state of conservation. The results have been combined with laboratory tests and a degradation simulation to fully characterize the main materials and determine the deterioration pattern.

Promising surface-active ionic liquid coatings for underwater cultural heritage conservation

Any submerged inorganic material is promptly colonized by a variety of microorganisms that offer the basis for the settlement of macroorganisms causing the so-called biofouling. The aim of this work is to evaluate applicability and durability of new designed coatings containing Surface-Active Ionic Liquids for the protection of underwater cultural heritage from the first step of biofouling formation. We report here the results of the characterization test performed on limestone and Carrara marble probes (colorimetric and capillary water absorption measurements) and of the UV weathering to evaluate the durability of these coatings. The results have shown that these coatings do not affect the original properties of the stone surfaces and they are stable over time.

Surface and stratigraphic analysis of black crusts using Laser Induced Breakdown Spectroscopy

The interaction between atmospheric pollutants and architectural cultural heritage leads to several degradation processes, mainly the formation of black crusts. Numerous studies have highlighted that their elemental composition can be used to determine the main pollutant sources of the surrounding areas. Therefore, black crusts may represent actual registries of pollution sources and may help to understand the evolution of these sources and their impact throughout the years. In this study, a first-ever application of the LIBS technique for the study of black crusts is carried out in order to evaluate the feasibility of this technique (surface analysis) and the in-depth distribution of the elements in the black crusts (stratigraphic analysis). The elemental profile of the black crusts enabled to detect the main pollution sources of the surrounding areas and the variation of their impact throughout the years.

From the context knowledge to Assessment of the Architectural Heritage decay: the case of Santa Maria di Vezzolano rectory (AT)

The rectory of Santa Maria di Vezzolano in Albugnano (Asti, Italy) has recently been the subject of a restoration project aimed at solving the deterioration involving the external walls and in particular the main façade. In order to support the plan of restoration project, geophysical and chemical investigations were carried out with the aim of investigating and understanding the causes of decay phenomena. The diagnostic campaign was aimed at documenting the water paths and at understanding which saline species were formed as a result of the progress of the degradation, understanding their origin (linked to capillary rising phenomena and consequent dissolution of constituent and/or restoration materials). Salts migration and consequently stone material erosion were correlated with the evidence provided by non-invasive techniques: the presence of water in the internal walls detectable in IR thermography, and in the subsoil, detectable by geoelectric investigation.

Study and restoration of the Sacra Conversazione by Lorenzo Berrettini and experimental tests to evaluate the application of diammonium phosphate as consolidant for the wall painting

This paper reports the study and restoration of a 17th century wall painting attributed to the artist Lorenzo Berrettini and located in a chapel of Palazzo Orsini at Bomarzo, a little town close to Viterbo, in central Italy. The wall painting was recently restored as activity of a master thesis in conservation and restoration of cultural heritage and on that occasion the artwork was investigated to characterize the materials and techniques with the aim at choosing the best consolidation procedure and product. To reach this goal, multispectral imaging and X-ray fluorescence spectroscopy were applied on-site. After this non-invasive analysis, some laboratory investigation was performed by Fourier transform infrared spectroscopy. The results of the diagnostic campaign were used to plan the experimental tests for consolidation by diammonium phosphate dibasic (DAP) that is a relatively new product in the field of restoration of wall painting. The tests demonstrated the good performance of this consolidant product, in respect to traditional nano-lime formulate.

Archaeometric investigations on ancient funerary stone elements from the National Archaeological Museum of Adria (Rovigo, Italy)

In this paper, we analysed 22 stone samples from Roman and Pre-Roman funerary artefacts found in the ancient Atria, which are currently preserved at the National Archaeological Museum of Adria. The analysis was conducted by Polarized Light Optical Microscopy (PLM) and X-Ray Fluorescence (XRF). Atria is situated in the deltaic plain of the Po River, far away from the rock formations historically exploited in the Veneto region of northern Italy. The objective of the research was to determinate the provenance of the stones to understand the trade networks that Atria relied on for obtaining stone materials and the quarries they exploited in antiquity. The results revealed the widespread presence of rock types sourced from the central-western part of Veneto. Among these, trachytes from the Euganean Hills were predominantly utilised, while the soft calcarenite known as Pietra Tenera di Vicenza from the Berici Hills and Scaglia Rossa limestone were used to lesser extent. Furthermore, the use of rhyolites for the construction of a Pre-Roman stele provides new insights into the stone resources quarried from the Euganean Hills prior the Roman era.
