Afficher plus [+] Moins [-]Buildings and monuments act as repositories of airbome organic pol1utants, which accumulate at the surfaces fonning black crusts. The organic compounds present in the black crusts col1ected from monuments located in four European cities, Brussels, Dublin, Rome and Seville were investigated and compared with those extracted from a diesel soot. The methods used were evaporation/pyrolysis and simultaneous pyrolysis/methylation. A complex mixture of compounds was identified in the crusts, mainly n-alkanes, n-alkenes, acyclic isoprenoids, fatty acids, aliphatic dicarboxylic acids, alkylbenzenes, benzenepolycarboxylic acids, polycyclic aromatic hydrocarbons, thiophenes, furans, pyridines, quinolines, benzonitriles, etc. These compounds were produced from total or partial combustion of petroleum derivatives. Similar compounds were obtained from diesel soot indicating that traffic around the most out standing monuments contributes to a continuous blackening of its walls.
