National Museum of Romanian Aviation is the only museum of its kind in the country who holds in a
historical succession the evolution of the Romanian aeronautics starting from Traian Vuia and Aurel Vlaicu
until today. Documents, models and aircraft exhibited in the museum, many of them being unique, can be
irreversibly degraded under the action of chemical air contaminants and/or inadequate microclimate
conditions. The article presents the results of air quality assessment within the main exhibition space of the
museum, Hangar 1, obtained in a study organized in 2014-2015. Given the specific of the museum and its
location, in a city with intense traffic, both indoor and outdoor concentrations of NO2, SO2, CO, O3, PM2.5 and
microclimate parameters (temperature and relative humidity) were monitored. Monitoring results showed
lower concentrations indoor than outdoor, I/O ratios fits in the interval [0.32; 0.8] except CO with an I/O ratio
situated close to the value 1. Averages concentrations were below those recommended by the American
Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) for air chemical pollutants
measured inside the museum, except ozone concentration whose average is in the hot season slightly
above the recommended limit but below the lower intervention limit, 50µg/m3. Microclimate parameter
values also fall into a range that implies reduced risk for various objects and books according to ASHRAE;
diurnal variations of microclimate parameters do not represent a danger for the exhibits in the museum,
also. Analyzing the information obtained by monitoring indoor air quality and statistical interpretation of
these data (I/O ratios, diagrams, Spearman correlation analysis) we can say that the air inside Hangar 1 and
microclimate conditions provided do not raise major problems for long-term conservation of the exhibits in
the museum and do not require additional measures in terms of air quality and microclimate parameters
