AbstractThin black layers often occur on building stone in polluted areas. Various techniques including scanning electron microscopy/energy dispersive X-radiography, electron spectroscopy for chemical analysis, Mossbauer spectroscopy and gas chromatography-mass spectrometry have been used to analyze these layers in samples from Sweden and some other European countries. The layers mainly consist of various iron oxides and iron oxide hydroxides, sulphates, soot and silicate minerals, with smaller amounts of metal, rubber and asphalt particles, and numerous organic constituents in low concentration. Air pollutants, and to some degree minerals from the interior of the stone, are the main source of the components which form the black layers.
