The indoor-outdoor comparison of volatile organic compounds was made in 52 private homes in the City of Munich, Germany. The VOC concentrations were measured by trapping with activated charcoal tubes and analyzed by capillary GC. The infiltrated NO, was monitored in the indoor air. It can be concluded that the benzene concentration in the indoor air is controlled by the outdoor concentration for approximatively 30 % of the investigated cases.
