Temporal and spatial variation of size resolved particulate matter (PM) was measured in the Baroque Library Hall of the National Library in Prague during four intensive campaigns by an Aerodynamic Particle Sizer and three DustTrak instruments. The analysis showed, the indoor air can be considered as well mixed and therefore the simple mass balance model was used to estimate basic parameters (ventilation rate, deposition rates and penetration factors). The results revealed that the movement of visitors during visiting hours is the main source of indoor coarse PM. Mass emission rates, estimated from the comparison of measured and modelled data indicates the visitors should contribute about 50 g of coarse particles yearly, which is about 35% of the total load of indoor PM.
