It is generally agreed that the role played by aerosols in determining the air quality in urban areas is steadily increasing. As well as being among the main agents responsible for today’s atmospheric pollution, atmospheric particles are also recognized to participate actively in damage layer formation. In fact, recent years have witnessed a marked acceleration in surface soiling phenomena, as can be observed in the continual blackening of monument surfaces located in polluted areas. While numerous authors have performed detailed studies on the impact of the sulphation process in monument decay on a world-wide scale, surface blackening remains in need of in-depth investigation. The EC project CARAMEL (Carbon content and origin of damage layers in European monuments) has as one of its fundamental work steps the analytical study of black crusts collected at different monuments located in European urban sites. The aim is to create a data base of the carbon fraction concentrations present, and understand their relationship with the content of aerosol carbon components.

Abstract
It is generally agreed that the role played by aerosols in determining the air quality in urban areas is steadily increasing. As well as being among the main agents responsible for today’s atmospheric pollution, atmospheric particles are also recognized to participate actively in damage layer formation. In fact, recent years have witnessed a marked acceleration in surface soiling phenomena, as can be observed in the continual blackening of monument surfaces located in polluted areas. While numerous authors have performed detailed studies on the impact of the sulphation process in monument decay on a world-wide scale, surface blackening remains in need of in-depth investigation. The EC project CARAMEL (Carbon content and origin of damage layers in European monuments) has as one of its fundamental work steps the analytical study of black crusts collected at different monuments located in European urban sites. The aim is to create a data base of the carbon fraction concentrations present, and understand their relationship with the content of aerosol carbon components.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
