Rice finding 70
Source evidence and comparison details for the Rice profile.
Polished (white) rice, market · Total arsenic (tAs) · 133 rice samples (63 speciated).
Selected finding and reference
133 rice samples (63 speciated). Basis: dry weight.
not reported; no non-detect handling described
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
India
Reported growing area.
Sampling, analysis and reporting limits
Total As by ICP-MS; speciation by HPLC-ICP-MS (methods of Williams et al.).
not reported; no non-detect handling described
Source inconsistency noted (does not affect this value): Table 1 prints min 0.31 mg/kg above max 0.18 mg/kg and above the mean 0.07; the text states the overall minimum 0.01 mg/kg was found in Egyptian, Indian and Thai rice, so the India min is likely a typesetting error for 0.01; extracted verbatim.
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.
