Rice finding 2135
Source evidence and comparison details for the Rice profile.
Imported rice, white/yellow/brown long, medium and short grain (form mix as sold) · Inorganic arsenic (iAs) · 24 rice samples (each analysed in triplicate).
Selected finding and reference
24 rice samples (each analysed in triplicate). Basis: unspecified in Table 5; exposure equation states Ci is concentration in raw rice (dry weight basis); samples ground, drying step not described.
Quantified values for all samples except where Table 5 prints 0 (Hg sample 28); DL approx 1 µg/kg (T-As, Cd, Pb, Hg), 0.5 µg/kg (i-As)
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
Imported rice (mixed forms)
Purchase or reporting market; growing origin not identified.
Sampling, analysis and reporting limits
Microwave HNO3/H2O2 digestion, ICP-MS (Agilent 8900 for As, Cd, Pb; Agilent 7700 for Hg); i-As by 0.28 M HNO3 95 °C extraction with HPLC-ICP-MS (FDA EAM 4.7 and 4.11).
Quantified values for all samples except where Table 5 prints 0 (Hg sample 28); DL approx 1 µg/kg (T-As, Cd, Pb, Hg), 0.5 µg/kg (i-As)
Source inconsistency noted (does not affect this value): lowest imported i-As in Table 5 is 50 µg/kg (sample 23, Pakistan), not 45.
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
| Source statistic | Original result | Displayed unit conversion |
|---|---|---|
| range | i-As of imported rice was detected in the range between 45 to 120 µg/kg | none (µg/kg) |

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.
