	abstract = {The filamentous fungus Scopulauiopsis brevicaulis biomethylates inorganic antimony(III) compounds to trimethylstibine, that can be detected in culture headspace gases. Dimethylantimony and trimethylantimony species have been detected in the medium of these cultures, but the origin of these species was controversial. We now show that the dimethylantimony species is a true intermediate on the pathway to trimethylstibine (rather than arising from trimethylstibine oxidation or as an analytical artifact) because no dimethylantimony species are formed on trimethylstibine oxidation, as determined by using HG-GC-AAS. Furthermore, the dimethylantimony and trimethylantimony species can be separated, by using anion exchange chromatography, and so the dimethylantimony species is not an analytical artifact, formed during the hydride generation process. The antimony biomethylation mechanism was further probed by measuring incorporation of the methyl group, from (CD3)-C-13-L-methionine and CD3-D-methionine, into methylantimony species and, for comparison, into methylarsenic species. The percentage incorporation of the labeled methyl group into methylarsenic and methylantimony species was not significantly different. The incorporation from (CD3)-C-13-L-methionine was 54\% and 47\% for antimony and arsenic, respectively. The incorporation from CD3-D-methionine was 20\% and 16\% for antimony and arsenic, respectively. It appears that the biomethylation of arsenic and antimony occur by very similar, perhaps identical, mechanisms. (C) 2000 Elsevier Science Ltd. All rights reserved.},

	abstract = {The filamentous fungus Scopulariopsis brevicaulis produces volatile trimethylstibine, found in the culture headspace, when grown in an antimony(III)-rich medium under aerobic conditions. The trimethylstibine was purged from cultures using a continuous flow of compressed air and trapped in a U-shaped tube containing Supelcoport SP 2100 at -78 degrees C. The trap contents were determined by using GC-ICP-MS methodology. Typically between 60 and 500 pg of trimethylstibine was trapped during sampling (12 h) from cultures containing 1000 mu g Sb ml(-1) as potassium antimony tartrate. The total production of trimethylstibine over 18 days of growth was estimated at 10 ng, Trimethylarsine was produced in greater quantities than trimethylstibine, even though no arsenic compounds were added to the medium, Copyright (C) 1999 John Wiley \& Sons, Ltd.},

	abstract = {ICP-MS is very sensitive and has limited matrix effects when used as an element-specific detector for GC in order to identify volatile metal or metalloid species, GC-MS is not very sensitive or selective in the electron ionization (EI) mode, but provides molecular information about volatile species. In this work, an ion trap EI-MS-MS and an ICP-MS system were used as two different detectors for the same GC system to provide complementary information about volatile organometallic species in the complex matrices of landfill and sewage sludge fermentation gases. A simple robust GC separation method with cryotrapping was adequate for the separation of the different metal(loid) containing volatile compounds, and was directly coupled to the ICP-MS system, In addition, gas samples from this GC system were collected in evacuated vials. These fractions were further separated on a capillary column and detected in an ion trap mass spectrometer. For the first time, parent ions, fragmentation patterns, isotopic ratios for Sb and Sn, and MS-MS data were used to identify positively Me3Sb, Me4Sn and Et2Me2Sn in landfill gas and Me3Sb and Me3Bi in fermentation gas.},
