Abstract

The field determination of selenium species was obtained after stripping 1 l of water, removal of the water vapour by a water trap, and cryofocusing in a small packed chromatographic column hyphenated to a non dispersive atomic fluorescence detector. Water trap and purging conditions were carefully studied. Under routine operating conditions, absolute detection limits of 4 and 4.5 pg of Se for Me2Se and Me2Se2 were obtained, respectively. Under routine conditions, linearity extended up to 1 ng as Se for the different species studied. The selectivity of the system is discussed in the presence of carbon-containing species. This system was applied to the determination of volatile selenium species in the Gironde estuarine environment (France). Me2Se was found to be the main volatile selenium species in concentrations ranging from 0.8 to 6.3 pmol l–1. Seasonal variations have been observed and commented upon. Correlation with water temperature and salinity is also discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
