Abstract
Total (wet + dry) deposition of ionic trace substances on the surfaces of a n historical monument (collegiate of Thann, France) was determined monthly using collectors plates. The most important compounds were SO42- (mean of 3 .89 mu eq.m(-2).d(-1)), Ca2+ (mean of 7.08 mu eq.m(-2).d(-1)) and Na+ (mean of 2.49 mu eq.m(-2).d(-1)). It was observed that the building itself was a source of particulate materials such as sodium salts and CaCO3. Sodium sal ts and acidic pollutants (H2SO4, HNO3 and HCl) play a role on the degradati on of the stone.
