Rice finding 1685
Source evidence and comparison details for the Rice profile.
Rice (form not specified; ground before analysis) · Total mercury (tHg) · 82 rice samples (>=500 g each).
Selected finding and reference
82 rice samples (>=500 g each). Basis: unspecified.
'-' indicates detected value below the corresponding LOD (Table 1 footnote); method LODs 0.001-0.02 mg/kg across metals (Table S4 not in text copy)
HMI baseline position
Limited data: The source reports a non-detect without a numerical limit; its position cannot be identified. Missing evidence never means low contamination.
The source reports a non-detect without a numerical limit; its position cannot be identified.
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
2021–2022
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Rice (n = 82)
Purchase or reporting market; growing origin not identified.
Sampling, analysis and reporting limits
microwave digestion HNO3/H2O2; ICP-MS (Thermo iCAP RQ); total As (no speciation).
'-' indicates detected value below the corresponding LOD (Table 1 footnote); method LODs 0.001-0.02 mg/kg across metals (Table S4 not in text copy)
This extreme or range value lies at or below the paper's own detection limit and is read as a reporting bound.
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.
Reported values, conversion and source locator

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.
