ABSTRACT
ABSTRACT: Assessment of atmospheric environmental risks related to tangible cultural heritage assets (CHas), in the context of their preventive conservation, is a key strategy to safeguard them. Here we summarize the results of atmospheric aerosol composition and its impact on Granada CHas. Investigations performed were: i) indoor and outdoor air pollutants identification and their effects on artworks used in closed and semi-open monuments, ii) field exposure tests to determine black soiling of limestones, and iii) ad hoc laboratory sea-salt ageing tests to learn about interactions between marine aerosols and carbonate stones with different surface finishes. Valuable information is provided and discussed about levels of atmospheric gaseous pollutants as well as chemical and mineralogical composition, size, and morphology of particulate matter, their concentration, trends, major sources and threats to artwork.
