Rice finding 1619
Source evidence and comparison details for the Rice profile.
Local Hassawi rice · Total mercury (tHg) · 9 rice samples.
Selected finding and reference
Basis: Ground uncooked grain; moisture basis unspecified. Results near method detection limits require caution, especially Hg. Displayed means do not assert every sample was detected.
HMI baseline position
Limited data: Held: Table 5 mercury values include zeros and low measurements with analytical dispersion of about 3 µg/kg, but no numerical reporting limit; the mean cannot be positioned without a bound. Missing evidence never means low contamination.

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 period not reported
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Saudi Arabia
Riyadh imports and Al-Ahsa local grain.
Sampling, analysis and reporting limits
HPLC-ICP-MS for iAs; ICP-MS for totals.
Results near method detection limits require caution, especially Hg. Displayed means do not assert every sample was detected.
Market imports span several countries and rice forms. No origin ranking or cooking conversion. SD definitions are not generalized from analytical replicates.
Shared samples and study overlap
24 imported and nine local samples; analyte rows reuse the same samples.
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.
