The study presents the effects of air pollution on a historical symbol of Cluj-Napoca. The statue of Saint George and the Dragon is a copy made in 1904 by Kalman Lux. The original statue built in 1373 by two metalworkers Martin and George from Cluj, is in Prague, Czech Republic. The pedestal of the statue was built using the “Baciu Limestone” due to its famous white color. The “Cluj Limestone” is a white-yellow Cenozoic limestone, with high water uptake and porosity, which allows large amounts of water to easily be stored within the limestone. According to the emissions inventory provided by The Regional Agency for Environmental Protection from Cluj-Napoca for the years 2004-2010 the emission values of SO2, NOx and SPM decreased comparing to the years 1992-2002, and the ammonia values were relatively constant. The results indicate the presence of a black layer of different thickness on the surface of the samples which consists mainly of new formed gypsum.
