Stony building materials as records of pollution

Abstract

[Excerpt] The elements of the built environment have the potential to constitute records of contamination as they react and fixate pollutants. Several aspects related to the potential application of stony materials in this regard would be discussed here. While the conditions of fixation of pollutants by humans and by materials surfaces have major differences, the studied of surfaces can be valuable in the comparison of exposition conditions. There is a special interest in the study of recent works and recent cleaned surfaces since there is higher potential for discrimation of signatures of pollution sources. [...]
