On a residential site in Gorinchem, which is polluted with vinylchloride and other chlorinated ethenes, measurements were carried out to assess the concentrations of the pollutants in the air of living-rooms and crawling-spaces of houses. Vinylchloride concentrations above the detection limit of the method (0.5 mug/m3) were not found either in the air of the crawling space or in the living-room in any of the six investigated houses. In three of the investigated houses a small contribution from the soil to the air in the crawling-space was found for tri- and tetrachloroethene. The concentration in the living-room, however, was well below the level of concern and did not exceed the normal concentrations for these compounds in the living-rooms. The concentration of cis 1,2, dichloroethene was not measured as calculations showed, that a relevant contribution from the soil to the living-room air is very unlikely.
