Abstract

An examination of the major anthropogenic and natural sources of atmospheric selenium indicates that approximately 13–19×109 g Se are cycled through the troposphere annually. Perhaps 60% of this flux is natural in origin, and both man‐made and biological emissions appear to be predominantly gaseous in nature. Emissions from the marine biosphere and the combustion of coal account for 50–65% of the total atmospheric selenium emissions, and the natural marine flux appears to be roughly twice as large as that due to coal combustion.

  • Global atmospheric selenium budgets indicate atmospheric selenium input fluxes between 15.5 and 15.7 × 10^9 g/year, of which about 60% are natural and 40% anthropogenic emissions, although the natural contribution was smaller (25%) in the northern hemisphere due to anthropogenic emissions.

    “Global atmospheric Se budgets [85,86,87,88,89] indicated that atmospheric Se input fluxes are between 15.5 and 15.7 × 109 g·year−1, of which ~60 and 40% are natural and anthropogenic emissions, respectively [40], although the contribution of natural emissions was found to be smaller (i.e., 25%) in the northern hemisphere due to anthropogenic emissions [90].”

  • 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]).”

  • Cutter (1993) estimated a deposition of 2.2 × 10^9 g Se/year over the North Atlantic Ocean, comprising about 12%-18% of total global emissions as estimated by Mosher and Duce (1987).

    “Cutter (1993) [97] estimated a deposition of 2.2 × 109 g Se year−1 over the North Atlantic Ocean, which comprises ~12%–18% of total global emissions as estimated by Mosher and Duce, 1987 [86].”

  • The main estimated anthropogenic source of atmospheric selenium is coal combustion, and the predominant natural atmospheric selenium source may be the marine biosphere via biomethylation of selenium by marine organisms.

    “The main estimated anthropogenic source is coal combustion (3 × 109 g·year−1 [86]; 1.83 × 109 g·year−1 [87]) and the predominant natural atmospheric Se source may be the marine biosphere via biomethylation of Se by marine organisms [40,91]”

  • Selenium concentrations measured in aerosols collected over the mid-North Pacific Ocean were concluded to originate from a dominantly biogenic input from the Bering Sea.

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.
