Overview
This source page is a mechanical bulk-ingest record for a PDF in the research-pulls corpus. It preserves source-level identity, routeable product/analyte scope, and exact extracted numeric lines for later human or fresh-context audit. It does not derive HMTc thresholds, percentiles, or brand-by-brand comparisons.
Key numbers
The worker extracted the full PDF text with layout preservation twice and compared extraction hashes before commit. The following lines are copied from numeric/table-bearing regions of the PDF and retain the source units and wording where legible:
- areas to alarming levels, reaching concentrations up to 27 µg/L in coastal waters (13).
- Elemental Hg0 allows for long-range transport (1), but only 10 to 30% of the total
- food webs, reaching up to 80–100% of the total Hg (THg) measured in fish muscle (1). The

- makes up approximately 18% of the total atmospheric Hg pool (28).
- have demonstrated that approximately 20–40% of the MeHg measured below the surface
- thrive in environmental conditions where Hg methylation occurs with pH in the 5 to 10 range. Re-
- dox potential from slightly negative (—0.4 mV) to zero, and dissolved oxygen of less than 0.2 mg/L.
- Adapted from (37–40). conditions where Hg methylation occurs with pH in the 5 to 10 range. Redox
- potential from slightly negative (−0.4 mV) to zero, and dissolved oxygen of less than 0.2 mg/L.
- The data listed in Table 1 provide insights into the distribution of Hg and MeHg
- Crimean saline lakes 129 ng/L - (54)
- Florida Bay (discharging canals) 3–7.4 ng/L <0.03–52% of THg (55)
- In Table 2 are listed recent studies of bioaccumulation of MeHg in marine or freshwater
- From Table 2, we can conclude that the most studied species for MeHg uptake and

- Nitzschia closterium 1 µg/L 72 h 32.74 µg/gDW (77)
- zones are defined as zones with less than 80 µM (2.9 mg/L) of DO, which deteriorate as
- 2023/915/EC, establishing maximum levels of Hg at 1 mg/kg for fish (88).
- CO2 sequestration while generating half of the O2 , which is equivalent to 1% of the global

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.

Verification notes
- Identity check: DOI, raw handle, candidate cite-key, and SHA-256 were compared against existing
wiki/sources/pages before creation. - Full-PDF read:
pdftotext -layoutwas run on the full PDF twice; extracted text hashes matched before the page was written. - Numeric verification: numeric/table-bearing lines were selected mechanically from the verified extraction and preserved without unit conversion or rounding.
- Brand firewall: the worker skips PDFs when extracted numeric lines appear brand/manufacturer-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.
