STATISTICAL FIELD SURVEY OF EXTERIOR BUILDING MATERIALS DEGRADATION
Corrosion damage to several important building materials presents clear connections with concentrations of air pollutants. The corrosive impact of, above all, sulphur dioxide (SO2) has been studied in both laboratory and field experiments. (e.g. Kucera, 1986)
The cost of corrosion damage inflicted by sulphurous emissions on building structures has been a subject of numerous studies in many different countries. An improved methodology for assessing the quantity and distribution of different materials in building structures in an urban area will make a big difference to the dependability of input data for calculating the cost entailed by emissions of acid pollution.
