Rice finding 2678

Source evidence and comparison details for the Rice profile.

Brombach et al. 2016

Rice products sold in Europe with European country of origin (presumed rice grain; form not stated) · Methylmercury (MeHg) · 12 retail rice products (packs homogenised, ~100 g milled subsample).

Selected finding and reference

6.45 µg/kg (maximum)Maximum.

12 retail rice products (packs homogenised, ~100 g milled subsample). Basis: unspecified (milled as-sold product; no moisture correction stated).

No non-detects reported; all values above LOD (tHg LOD 0.02, MeHg LOD 0.12 µg/kg)

HMI baseline position

Limited data: The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference. Missing evidence never means low contamination.

The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference.

Reference version and interpretation

Frozen evidence selection: 2026-10-22. Method: hmi-pooled-reference-v2.

No admitted reference

The reference is computed by HMI from admitted evidence, not copied from a study baseline. It describes the evidence currently in this scope; it is not a worldwide or current-lot benchmark. Source, year and region filters do not change it. Different HMI scopes are not one common ranking.

Collection period

No year-by-year sample register is reconstructed from this summary.

Europe

Reported growing area.

Sampling, analysis and reporting limits

Total Hg: HNO3 hot-block digestion + BrCl, CV-AFS; MeHg: TMAH microwave extraction, thiol/thiourea SPE preconcentration, HPLC-CV-AFS; 19-sample subset also by SS-ID-GC-ICPMS.

No non-detects reported; all values above LOD (tHg LOD 0.02, MeHg LOD 0.12 µg/kg)

Shared samples and study overlap

Subgroup rows, statistics of the same subgroup and the study total share samples; they are not independent results.

Each table row describes a food/analyte result. Repeated rows do not add independent samples or datasets. No cross-study trend is calculated in this comparison mode.

No moisture, cooking-yield or species conversion is applied to the original finding above. Any basis conversion used for its HMI comparison is stated separately with the numerical target.
