Rice finding 79

Source evidence and comparison details for the Rice profile.

Meharg et al. 2009

Polished (white) rice, market · Total arsenic (tAs) · 76 rice samples (63 speciated).

Selected finding and reference

50–820 µg/kg (range)Range.

76 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

Spain

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

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.
