Rice finding 2273
Source evidence and comparison details for the Rice profile.
Commercial rice (white and 'wild' mixture) · Inorganic arsenic (iAs) · 3 commercial rice samples (single packages, replicate determinations).
Selected finding and reference
3 commercial rice samples (single packages, replicate determinations). Basis: unspecified.
none
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
commercial rice samples
All samples in the study.
Sampling, analysis and reporting limits
Total As: microwave HNO3/H2O2 digestion, ICP-MS (NexION 300X). As species: ultrasound-assisted extraction (1:1 methanol/water), ionic-imprinted-polymer vortex-assisted dispersive micro-SPE pre-concentration (factor 10), HPLC-ICP-MS (PRP-X100), standard-addition quantification.
none
Source inconsistency noted (does not affect this value): the text range (30±5 to 213±16 µg/kg) does not match Table 4, whose highest commercial iAs is 127±13 µg/kg (Basmati) and whose Jasmin SD is ±11, not ±5. No sample at 213 µg/kg appears in the table; the table rows are the itemized values.
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.
