Gama et al. 2025

Polished white short-grain rice (Carolino) · Total arsenic (tAs) · 3 rice grain samples (one per harvest/type).

Selected finding and reference

70–100 µg/kg (range)Range.

3 rice grain samples (one per harvest/type). Basis: unspecified (grains milled to powder; drying not stated).

As reported by the source

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

2020–2022

No year-by-year sample register is reconstructed from this summary.

Geographic scope

Polished white rice

Rice variety or type within one study.

Sampling, analysis and reporting limits

ICP-MS (Agilent 7700) after HNO3+H2O2 digestion of 0.25 g milled grain; at least two aliquots per sample.

As reported by the source

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.
