Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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]).”

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.
