The Atmospheric Pollution Influence on the Surface Structures of Porous Geomaterials in Correlation with Some Natural Radionuclides

Abstract

In the current context of climate and environmental changes, knowledge on the degradation and deterioration of the geomaterials mechanisms existing in the structure of both buildings and historical monuments becomes a priority due to the influence of atmospheric pollutants on apparent lithic surfaces. The aim of the paper is to highlight the impact of pollution on the surface structures of some porous carbonate rocks, where a series of radionuclides and heavy metals have been identified. Taking into account that these rocks are considered as commonly used local building material, being utilized also for the construction of the medieval and pre-modern historical monuments from the city of Iasi, the study draws attention to the detailed assessment of their conservation status from the built heritage in relation to the surrounding environment.
