Abstract
Much basic knowledge is still required as to the effects of multipollutants on
historic monuments and buildings. Since black crust formation on monuments is
due to the deposition of airborne pollutants on areas sheltered from wash out, the
discrimination and measurement of their carbon components is fundamental for
the partitioning of air pollution sources and the identification of the damage
mechanisms involved. Such knowledge is an essential prerequisite for the
maintenance of modern buildings, as well as the protection of ancient masonry.
The total carbon (Ct) in damage layers can be considered as being com
