Characterizing the Exposome of Food Contamination and China Total Diet Study: Project for Improving Food Safety Risk Assessment in China

Overview

This source page is a mechanical bulk-ingest record for a PDF in the Heavy Metal Index raw corpus. It preserves source-level identity, routeable analyte and product scope, and the exact extracted numeric lines that justify that scope, for later human or fresh-context audit. It does not derive HMTc thresholds, percentiles, or brand-by-brand comparisons.

Author, year, and title are taken from the Crossref record for the DOI, not scraped from the PDF text.

Key numbers

Each analyte named in metals: is listed below with the measurement-bearing lines that caused it to be asserted. Lines are copied from the verified extraction and retain the source units and wording where legible. An analyte with no lines here would not appear in the frontmatter.

Cd

• Lead (Pb) and cadmium (Cd) are heavy metal carcinogenic. For adults, Pb exposure of 1.2 μg/kg
• FIGURE 2. Dietary intake of cadmium for adult male in 24 PLADs from the Sixth China TDS, 2016–2019.
• cadmium dietary exposure among residents in Nanjing, 2013-2016.
• SUPPLEMENTARY TABLE S1. Comparison of dietary intake of lead and cadmium with other countries.

Methods (brief)

• Results lower than LOD were assigned 1/2 LOD in calculations.
• study/ND=1/2 LOD (n=50) 154, and 183
• study/ND=LOD population breads, eggs, vegetable 153, 154, 155, and

• 4. Zacs D, Perkons I, Abdulajeva E, Pasecnaja E, Bartkiene E, Bartkevics V. Polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes
• samples were collected from 24 provincial-level concentrations below the limits of detection (LOD)
• administrative divisions (PLADs) in the Sixth China were set to be LOD/2.
• spectrometry (ICP-MS). The limit of detection (LOD)

Implications

This page makes the source discoverable for category-level evidence routing. Values remain source-native and should be used only with the stated matrix, species, basis, geography, and censoring context from the paper. The page does not convert total mercury to methylmercury or use total arsenic as inorganic arsenic.

Wiki pages this source may touch

• Fish — marine, non-predatory (sardines, anchovies, salmon, cod)
• Shellfish (shrimp, crab, lobster, clams, oysters, mussels)
• Cadmium

Verification notes

• Identity check: DOI, raw handle, cite-key, and SHA-256 were compared against existing wiki/sources/ pages before creation.
• Provenance: first author and publication year resolved from Crossref for DOI 10.46234/ccdcw2022.039. PDFs whose DOI does not resolve are skipped, not given a fallback key.
• Full-PDF read: pdftotext -layout was run twice and the extraction hashes compared before the page was written.
• Analyte scope: each metal is asserted only where its spelled-out name appears on a line carrying a measurement. Element symbols alone never assert an analyte.
• Brand firewall: the worker skips PDFs whose numeric lines appear brand-sensitive; this page contains category-level or species-level evidence only.
• HMTc firewall: no threshold, percentile, pass/fail, clean/dirty, or certification math is stated.

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.
