Abstract: | Following the observation of volatile hydride and methylated arsenic species in the gases released from sewage treatment facilities and municipal landfills, we have developed a method for investigating the production of such gases by an anaerobic organism. Here we report the application of high performance ion chromatography (HPIC), hydride generation gas chromatography (HG-GC), and purge and trap gas chromatography (PT-GC), coupled with inductively-coupled plasma mass spectrometry (ICP-MS) to study the formation of ionic and volatile arsenic compounds produced in a batch culture of the anaerobic methanogen Methanobacterium formicicum. In this time course experiment we observed arsenite, mono- and dimethylated arsenic acid, arsine, mono-, di- and trimethylarsine, as well as a currently unknown volatile arsenic species. |
