Abstract Gas chromatography and high-performance liquid chromatography coupled to a double focusing sectorfield ICP-MS as sensitive element specific detector are used for the speciation of arsenic of liquid and gaseous emissions from soil samples, which were equilibrated in a microcosmos experiment. Speciation of liquid samples was performed by HPLC and hydride generation was used as introduction system to ICP-MS. An online prereduction step was introduced to enhance the sensitivity for As(V). A home-built and laboratory-ready transfer line from GC to ICP-MS is presented and quantification of As in gaseous emissions was performed by external calibration via hydride generation. The microcosmos experiment revealed only low production rates of organoarsenic compounds and reflected a limited capability of the biovolatilization experiment for the simulation of natural systems.
