Abstract

The adsorption of vapours of different volatility and polarity on three materials widely used indoors 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. The experiments show that: (i) adsorption seems to occur to at least two different sinks with different rate constants in the same material; (ii) generally, adsorption increases with the boiling temperature of the compounds, but it depends also on other physico-chemical properties as well as on the sorbent material.
