Abstract
Introduction. The purpose of the article is to assess the quality of indoor air in university by measuring the concentration of suspended particles. In the Russian Federation, the rationing of maximum permissible concentrations of undifferentiated dust in atmospheric air depends on particle size.
Materials and methods. The research carries out measurements of suspended particles concentrations in the air of six audiences in the Moscow State National Research University of Civil Engineering (NRU MGSU).
Results. The obtained results of concentration measurements (particle/m3) are recalculates in mg/m3, and compared with threshold values of maximum one-time concentrations of suspended particles.
Discussion and conclusions. In calm weather, air pollution by suspended particles in the surface layer practically does not affect the quality of internal microclimate, which is associated with significant decrease of dust concentration in height and insufficient air exchange in natural ventilation systems.
