The wall paintings of the Michelozzo's Courtyard (XVI century) at the main entrance of Palazzo Vecchio in Florence are in an advanced state of degradation. With the aim of understanding the environmental conditions in the Courtyard a wide research project has been instigated. In this study, the fine and coarse fractions of the PM10 have been collected by a 'streaker' sampler with an hourly resolution and then analysed by PIXE at the 3 MV tandetron accelerator in Florence; the first results will be presented here.
