Impact of the urban pollution on the indoor environment - experimental study on a mechanical ventilated dwelling

Measurements were carried out to assess the transfer of outdoor air pollution (CO, SO2, NO, NO2, O3, BTEX, TVOC, fine particles, smoke index) into an unoccupied and empty dwelling in Paris, in winter and summer. The controlled air exchange rates were 0.6 and 0.9 volume/h. Some pollutants have a reduced concentration indoors (NO, SO2, O3, particles, smoke index) as others are transferred (like CO). Some results were also obtained with sorbing materials inside the dwelling, which reduce indoor concentrations.
