Overview
Stub. This section is a planned home for analytical-method, detection-limit, and laboratory-program reference content. Pages here will support the wiki’s occurrence-data claims by documenting what analytical confidence those numbers actually carry.
Planned topics:
- ICP-MS — Inductively coupled plasma mass spectrometry — Inductively coupled plasma mass spectrometry, the dominant trace-metal analytical method underlying nearly all post-2000 food-occurrence datasets cited in this wiki.
- EN 1811 Nickel Release Testing — nickel release from skin-contact articles and piercing post assemblies, reported as µg/cm2/week rather than food ppb.
- HPLC-ICP-MS arsenic speciation methods (separating iAs from organic As species) — covered as a hyphenated configuration on the ICP-MS page; a dedicated speciation page is planned.
- AOAC and EPA validated methods commonly cited in regulatory documents.
- Round-robin and proficiency-testing programs (FAPAS and others) that bound inter-laboratory variability.
- Field-sampling and homogenization considerations specific to heavy-metal occurrence surveys.
- Reporting-limit conventions and the treatment of left-censored data in occurrence statistics.
External references this section will draw on:
- Jakubowski 2012 — detection-limit tables for cadmium analysis methods.
- FDA TDS 2018-2020 — FDA Total Diet Study analytical methods documentation.
- Codex CXS 193-1995 — Codex methods of analysis and sampling references for matrix-level MLs.

Update history
The five most recent substantive edits to this page, classified major (evidence or structure moved), correction (a published value or statement was wrong and has been fixed), or minor (narrative rewritten without changing the underlying evidence). Each description is derived from what the edit did to this page; the linked commit is the authoritative record, routine regeneration passes are excluded, and the full version history lives in git. When DOI minting comes online (see schema docs), each entry below will also link to a version-pinned DataCite DOI.
