Maritime emission of selenium to the atmosphere in Eastern Mediterranean seas
Abstract
Results presented in this article report the first assessment of at least 3 volatile selenium species (MeSeH, DMSe, DMDSe) in marine water and air. Dimethyl selenide (DMSe) was the main compound encountered and the total concentration of the volatile selenides was found to be correlated with the marine plankton biomass as measured through chlorophyll a content. Estimation of a net selenium flux from the ocean to the marine atmosphere has been established. This gaseous flux corroborates previous hypotheses on selenium cycling and indicates that maritime emissions are a major source of selenium to the atmosphere in the Mediterranean basin.

Field measurements of biogenic selenium species in the marine environment and global-scale extrapolations indicate that biogenic selenium emissions from the marine environment may be larger than previously estimated.
“field measurements of biogenic Se species in the marine environment and global-scale extrapolations of these observations indicate that biogenic Se emissions from the marine environment may indeed be larger than previously estimated (28.5 × 109 g Se year−1 [96] and 35 × 109 g Se year−1 [91] compared to 0.4–9 × 109 g year−1 [86,88]).”

In the open marine environment, concentrations of DMSe and DMDSe are usually lower: 0.14-4.73 pM DMSe and 0.02-0.11 pM DMDSe in the North Atlantic and 0.06-0.64 pM DMSe and 0.07-0.26 pM DMDSe in the Mediterranean.

In addition to DMSe and DMDSe, the volatile Se species MeSeH and the mixed Se-S species dimethyl selenylsulfide have been identified in natural waters.

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.
