The paper presents the results of preliminary investigations on the applicability of commercial polyethylene films to permeation-type passive samplers for the preconcentration of organic indoor air pollutants. The samplers were calibrated in exposure chambers in the atmosphere of standard gaseous mixtures containing vapours of m-xylene, styrene, m-dichhobenzene and cyclohexanone – volatile organics often encountered in indoor atmospheres. The permeation rates remained constant for all the film in the entire investigation period (9 months). Of the materials examined, the most suitable proved to be Cryovac EFDX 003 (28 μm), ensuring the highest permeation rates.
