Quantitative assessment of worldwide contamination of air, water and soils by trace metals

Nriagu, Jerome O., Pacyna, Jozef M.·1988·Nature

Abstract

Calculated loading rates of trace metals into the three environmental compartments demonstrate that human activities now have major impacts on the global and regional cycles of most of the trace elements. There is significant contamination of freshwater resources and an accelerating accumulation of toxic metals in the human food chain.

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?

  • 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]”
  • 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].”

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.
