Rice finding 297
Source evidence and comparison details for the Rice profile.
Rice grain, form unstated (Vietnamese 'gạo', milled rice as sold) · Total arsenic (tAs) · 9 rice samples.
Selected finding and reference
9 rice samples. Basis: unspecified.
no non-detects reported; all 32 samples above LOD 0.01 mg/kg (minimum 0.058 mg/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
Collection date unreported
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Supermarkets in Hanoi
Purchase or reporting market; growing origin not identified.
Sampling, analysis and reporting limits
~0.5 g homogenised sample, microwave digestion (7 mL HNO3 70% + 1 mL H2O2 30%, Ethos One), total As by hydride-generation AAS (Shimadzu HVG/AA-7000) per TCVN 6626:2000.
no non-detects reported; all 32 samples above LOD 0.01 mg/kg (minimum 0.058 mg/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.

Abstract (p.282) and Section 3.1 (p.285); Conclusion (p.286).
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.
