Abstract

Impact of fuel reformulation on pollutioninduced stone degradation P. Buttini & G. Perego Department of Physical Chemistry EniTecnologie Monterotondo, Rome, Italy. Abstract The combined effects of SO2 and particulate matter on stone degradation have been investigated through experiments conducted both in a simulation chamber and in rural and urban environments. Specimens of calcareous stone have been used in the experiments, after they have been exposed to the exhaust of gasoline light duty, light and heavy-duty diesel vehicles. An appropriate glass chamber has been constructed in which the stone specimens could be maintained in a controlled atmosphere (in terms of sulphur dioxide and humidity concentration). Typical rural and urban sites have been chosen for outdoor exposure. For both sites detailed data on particulate matter and conventional air pollutants have been achieved. The contribution of pollution sources has been calculated by receptor models and extracted horn local emission inven
