Rice finding 2679
Source evidence and comparison details for the Rice profile.
Rice grain and rice products (mixed, excluding the 9 baby rice products): 75 rice-grain samples (incl. 3 wild rice) plus 2 rice noodles and 1 rice flour · Methylmercury (MeHg) · 78 retail rice products (packs homogenised, ~100 g milled subsample).
Selected finding and reference
78 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: No compatible reference units exist for this analyte, material and basis after the complete rice ledger. Missing evidence never means low contamination.
No compatible reference units exist for this analyte, material and basis after the complete rice ledger.
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
Collection date unreported
No year-by-year sample register is reconstructed from this summary.
Geographic scope
other rice products
All samples in the study.
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.
