As important as preservation of the environment is the preservation of our cultural heritage for future generations Atmospheric pollution is not only prejudicial for human health, it is also associated with degradation of cultural heritage. For this reason, many studies about the presence of such pollutants in the internal atmosphere of several museums were made all over the globe. These researches are essential to obtain knowledge about the indoor air of the museum and provide data for the correct implementation of preventive conservation. The Oscar Niemeyer Museum (MON), in Curitiba, Paraná, has recently opened in a modern building structure, and has numerous modern and contemporary art pieces, and recives art expositions from others brazilians states. In this research, Oscar Niemeyer Museum’s atmosphere was analysed. Samples of urban gaseous pollutants (NO2, SO2, O3, HAc, Hfor, BTEX) and suspended particulate matter were collected. The gaseous pollutants were collected with passive samplers and analysis performed by ionic and gaseous chromatography. The analysis of the bulk particulate matter was performed by energy dispersive X-ray fluorescence analysis. For the analysis of single particles, electron probe X-ray microanalysis measurements were made. Most of the concentrations found for the pollutants were bellow recommended exposure values (NO2 8,1 µg m-3, SO2 0,57 µg m-3, O3 2,2 µg m-3, average values). The BTEX concentrations were similar to those found in another museums, except the o m + p xilen (16,6 µg m-3) and o-xilen (38,5 µg m-3) concentrations, witch were affected by the painting of a room near the sampling site. The concentrations for particulate matter bulk analysis inside the museum were smaller of those found outside, and the average value for those particles considered most aggressive, S-rich, Cl-rich and e-rich, were bellow 60 ng m-3. The single particle analysis reveled that the relative abundance of the most aggressive particles, such as organic particles, soot, Fe-rich particles and CaSO4, was similar to those found in other museums. These concentrations were then compared with the concentrations obtained for the same pollutants in others world museums and with some reference values provided by international cultural heritage conservation centers. Some preventive conservation action suggestions were made, when thought necessary, based on the pollutants concentration found inside the museum
