Popis:	The development and evaluation of a device for meauring soil-air fluxes of organic contaminants is presented. The sampler is deployed at the ground surface and measures fluxes coming to the surface by using a passive sampling element. A computer model is used to aid the design and calibration of the sampler. Laboratory tests of prototype samplers are used to verify the model and to determine the accuracy and precision of meaurements. Several field demonstrations are conducted in which results are compared to conventional measurement approaches
