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.
