Abstract

Further to the successful completion of our study that measured the arsenic and chromium levels on children s hands after playing in playgrounds, this study will extend to measure biomarkers of exposure. Chromium and arsenic speciation in saliva and urine samples from the participating children will be determined and will be used to assess children's overall exposure to arsenic and chromium.To address some concerns over arsenic in game meat and traditional foods of the First Nations, moose and deer meat as well as cattail plant samples collected from First Nations communities in Northern Alberta will be studied for arsenic speciation. The chromatographyand mass spectrometry techniques that have been developed during the previous period will be applied to the characterization and quantitation of arsenic species in these food samples. The skin and starchy tuber of cattail plants will be analyzed separately because ourpreliminary results have shown that elevated arsenic levels are found to be localized on the surface (skin) and fine roots of cattail. This separate analysis is important because it is the starchy tuber that is usually consumed. The speciation techniques will further be adapted and applied to studies of vanadium speciation in oilsands and processing by-products. Release of relatively high levels of vanadium from oilsands is a potential environmental concern that requires attention.

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?

  • Reductive dissolution of Fe and Al metal oxides along with activity of indigenous metal-reducing bacteria is a prominent release mechanism of As, directly affecting As mobility.

    “Reductive dissolution of Fe and Al metal oxides along with the activity of indigenous metal reducing bacteria is now deemed as the prominent release mechanism of As, directly effecting the mobility of As [32, 33].”

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.
