Abstract

Arsenic metabolism in macroalgae has gained considerable interest because it controls the risk of arsenic contamination in algal products. This article reviews the total and inorganic arsenic contents in seaweeds, including 92 (red), 154 (brown) and 36 (green) species belonging to Rhodophyta, Phaeophyta and Chlorophyta, respectively. All the data collected from the published seaweeds support the conclusion that the total and inorganic arsenic contents in seaweeds are category-dependent, with species from Phaeophyta having the highest and those from Chlorophyta having the lowest. Total arsenic contents in the top 10 species of Phaeophyta are all over 100 mg kg⁻¹ DW, but those in the top 7 species of Rhodophyta and the top 3 species of Chlorophyta vary from 20 to 50 mg kg⁻¹ DW and 10 to 15 mg kg⁻¹ DW, respectively. The average total and inorganic arsenic contents in species of Phaeophyta are significantly (P < .05) higher than those in species belonging to Rhodophyta and Chlorophyta. Furthermore, Phaeophyta also contain a much higher percentage of inorganic arsenic with respect to total arsenic than either Rhodophyta or Chlorophyta. In addition, this article also reviews the effects of environmental factors on the absorption, bioaccumulation and biotransformation of arsenic species in seaweeds.

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

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Seaweeds and microalgal species growing in polluted waters can accumulate significant concentrations of toxic metals such as arsenic, cadmium, lead, mercury, and aluminum.

    “Seaweeds and microalgal species growing in polluted waters, especially those near industrial zones, mining areas, poorly managed sewage systems, or regions exposed to natural geological activity, can accumulate significant concentrations of toxic metals such as arsenic, cadmium, lead, mercury, and aluminum [219,220].”

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.
