Rice finding 1556

Source evidence and comparison details for the Rice profile.

Mohammadi et al. 2024

Champa rice after harvesting and husking (described as raw white rice in Section 2.3); washed with double-distilled water before analysis · Lead (Pb) · Sample count unreported.

Selected finding and reference

20–210 µg/kg (range)Range.

Sample count unreported. Basis: dry weight.

No non-detects reported; LOD not reported

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.

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.

Sampling, analysis and reporting limits

Washed, oven-dried 110-120 °C, ashed at 151 °C (as printed), 1 g extracted with 4 M HNO3 at 95 °C; Varian 710-ES ICP atomic emission (ICP-OES).

No non-detects reported; LOD not reported

Source inconsistency noted (does not affect this value): reported mean 1.1265 mg/kg lies far outside the reported min-max 0.0200-0.2100 mg/kg, and the CV 0.501 is inconsistent with SD 0.0634/mean 1.1265 (0.056); the text says Lordegan Pb is about 7 times the 0.15 mg/kg Iranian limit (~1.05), which matches the mean but not the range. Either the mean or the

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.
