Several exposure campaigns of silica–soda–lime window glass have been performed in 30 European sites and 1 in Canada in order to understand, quantify and model the phenomenon of soiling. In this purpose samples were exposed sheltered from the rain. Parallel to exposure, several meteorological parameters and pollution concentrations have been monitored. This paper shows first results on the establishment of a dose–response function for glass soiling. Statistical analyses show that PM10 is not the only parameter, but also SO2 and NO2 atmospheric concentrations seem to be responsible for the optical impairment of glass surfaces, expressed as haze.
