Sorption and Diffusion of volatile organic compounds in and by indoor materials have been studied by small-scale chamber experiments. VOC-uptake by building materials can be high, and diffusion can take place in any materials. Possible practical implications of the experimental results are pointed out by performing simple steady-state calculations within a model room. It may be concluded that at low ventilation rates and for open wall materials diffusion can contribute to a decrease of the concentration of the VOC. The masonry of a room may significantly alter the time required to remove a compound from the system.
