| Content Summary | The impact from the indoor dry deposition of size-resolved particles was investigated in the present study. Published data from a baroque library in Prague, two medieval churches in Cyprus and two historical churches in Poland were used in the present study. Values of the deposition velocity vd obtained in literature from these studies were used to examine the comparative impact on the preservation of indoor collections in relation to particle size and indoor concentrations. The number of deposited particles was estimated at different particle sizes for cases where number concentration data were available whilst the mass flux towards indoor surfaces was obtained from the particle mass size distribution. Additionally, a dose-response function was implemented to investigate the acceptable level of soiling regarding the aesthetic impact from the deposition of indoor particulate matter. The results demonstrate that higher number of deposited particles are found in the lower part of the size distribution (fine particles), whereas, an opposite behavior was obtained for the mass flux where higher flux was obtained for coarse particles. These findings were directly associated with indoor particle dynamics at the different sizes and the corresponding concentrations. Particularly, higher accumulation on indoor surfaces by fine particles was linked with a relative effect of these particles for deposition on vertical-oriented surfaces whereas the large amount of deposited mass arising from coarse particles was attributed to a potential impact on horizontal surfaces. Furthermore, the dose-response function showed a proportional relationship between the soiling constant and the PM10 concentration, with indoor sites characterized by elevated concentrations being more risky for the preservation of indoor works of art. In general, the results of the present study highlight the necessity of a common assessment of the indoor particle size distribution and the corresponding chemical composition for better analysis of the effect due to dry particle deposition. | en |
