Terrestrial eutrophication of building materials and buildings: An emerging topic in environmental studies

Abstract

Eutrophication has been analyzed mostly in aquatic or soil environments to date. Direct terrestrial eutrophication of building materials and buildings, contrary e.g. to their biodeterioration or biodegradation, was studied so rarely that even its exact definition does not exist yet. In this paper, eutrophication of building materials and buildings as an emerging topic in environmental studies is analyzed in detail and future developments in the field are contemplated. The analysis includes a survey of directly and indirectly related research studies, identification of basic mechanisms and principal factors, and a critical assessment of current methodologies potentially applicable for recognition and classification of eutrophication of building materials and buildings. A definition of direct terrestrial eutrophication of building materials and buildings is proposed afterwards and an alternative method for the calculation of their eutrophication potential is suggested. Finally, recommendations for solving the most urgent problems in future research are formulated.
