Natural and anthropogenic sources of total suspended particulate and their contribution to the formation of black crusts on building stone materials …

2012

Blackening and disaggregation of exposed surfaces of stone monuments are well-known effects of stone decay taking place in polluted urban environments all over the world. This paper aims to assess the contribution of natural and anthropogenic sources of total suspended particulate (TSP) causing permanent damage (black crusts) to the stone monuments of Catania (Sicily), one of the most popular ‘‘cities of art’’ of southern Italy. Atmospheric pollution of Catania, a typical Mediterranean coastal town, is mainly contributed by vehicle exhaust emissions rather than industrial ones. Episodically, the city also suffers gaseous and ash emissions (plumes) from the nearby Mount Etna volcano. Thus, t…

A new historical perspective regarding the baptismal font of the cathedral of Monreale (Sicily): the identification of a reused Roman labrum by an an…

The Cathedral of Monreale (not far from the city of Palermo) is one of the most famous monuments of the Arab-Norman period in Sicily recently added to the World Heritage list by UNESCO. It is well known above all for its structure and the magnificence mosaic decorations inside. In the church it is also conserved a Baptismal Font made of coloured limestone and dated back to the first decade of the 17th century. The present study deals with this valuable object with the aim of obtaining information about the nature and provenance of the coloured limestone constituting the basin. Laboratory analyses were thus carried out on representative stone samples by means of polarized light microscopy as…
