Impacts of air pollution and climate on materials in Athens, Greece

John Christodoulakis, Chris G. Tzanis, Costas A. Varotsos, Martin Ferm, and Johan Tidblad

Abstract. For more than 10 years now the National and Kapodistrian University of Athens, Greece, has contributed to the UNECE (United Nations Economic Commission for Europe) ICP Materials (International Co-operative Programme on Effects on Materials including Historic and Cultural Monuments) programme for monitoring the corrosion/soiling levels of different kinds of materials due to environmental air-quality parameters. In this paper we present the results obtained from the analysis of observational data that were collected in Athens during the period 2003–2012. According to these results, the corrosion/soiling of the particular exposed materials tends to decrease over the years, except for the case of copper. Based on this long experimental database that is applicable to the multi-pollutant situation in the Athens basin, we present dose–response functions (DRFs) considering that dose stands for the air pollutant concentration, response for the material mass loss (normally per annum) and function, the relationship derived by the best statistical fit to the data.

Short summary
In this paper we present the corrosion/soiling results obtained from the analysis of different kind of materials that were exposed in Athens during the period 2003–2012. According to these results, the corrosion/soiling of the particular exposed materials tend to decrease over the years, except for the case of copper. Based on this long experimental database, applicable to multi-pollutant situation of the Athens basin, we present newly developed dose–response functions (DRFs).
