Single particle analysis has been performed on airborne particulate matter (APM) collected at the Alhambra monument, using micro-Raman spectroscopy (MRS) and electron probe X-ray microanalysis. MRS and molar abundance ternary diagrams elicited the chemical structure of individual APM. The APM proved to be largely acidic, hygroscopic and/ or carbonaceous in composition, resulting in potential chemical attack and soiling of the artefacts.
