Adsorption of selected volatile organic compounds on a carpet,a wall coating and a gypsum board in a test chamber.

The adsorption of vapours of different volatility and polarity on three materials widely used indoors (carpet, gypsum board, wall coating) has been investigated in small test chambers, in order to study methodological aspects and to estimate the importance of the phenomenon for human exposure assessments. The output of the models used, with rate constants describing two different sinks, is discussed.
