William Shotyk’s commentary in Canadian Chemical News (May 2006, pages 18 to 20) connects antimony in Arctic snow with antimony in water bottled in PET. No DOI was verified for this item. It overlaps the Journal of Environmental Monitoring paper by Shotyk, Krachler, and Chen, which is ingested separately. Numbers that belong only to that paper are not repeated as if this commentary measured them. Figure averages that appear only in the graphic are not repeated as numbers.
Key numbers
The commentary states a limit of detection of five parts per quadrillion, that PET typically contains several hundred mg/kg of antimony, that a German commercial source water contained four parts per trillion of antimony before bottling, and that water in PET contained up to 30 times more antimony than the comparison the author is drawing with glass. An enrichment of Arctic antimony “over three decades” is discussed, A numeric enrichment over those decades is not stated as a single percentage in the prose, so none is entered.
Methods (brief)
Commentary, not a new analytical campaign.
Evidence fitness
The sentences above are the commentary’s own statements. They are not a substitute for the JEM table.
Limitations
No verified DOI. Figure values that exist only as graphics are omitted. Evidence tier C because this is a magazine commentary rather than the research article.
