Dose-response function for the soiling of silica-soda-lime glass due to dry deposition

摘要

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 PM_(10) is not the only parameter, but also SO_2 and NO_2 atmospheric concentrations seem to be responsible for the optical impairment of glass surfaces, expressed as haze.
