摘要：

One of the dominating problems in the revitalization of brownfields in region of Sao Paulo City, Brazil, is the assessment and quantification of vapor intrusion scenarios that trigger frequently necessary remedial actions. With a flux chamber based investigation procedure in combination with a new developed GC-system for the detection of chlorinated volatile organic compounds (CVOCs) site specific soil vapor fluxes could be quantified. Based on the results of flux chamber experiments the effectiveness of concrete slabs could be shown to reduce the vapor flux into enclosed spaced. Moreover, the obtained vapor flux rates were used to predict resulting indoor air concentration due to vapor intrusion of CVOCs.
