Rice finding 594
Source evidence and comparison details for the Rice profile.
Rice grain unspecified · Cadmium (Cd) · Sample count unreported.
Selected finding and reference
Sample count unreported. Basis: dry weight.
none 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.
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
2021
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Cd category 5
All samples in the study.
Sampling, analysis and reporting limits
0.20 g dried sample, HNO3 closed PTFE digestion 150-170 °C, ICP-MS (PerkinElmer NexION 2000) per Chinese multi-element food method.
none reported
Source inconsistency noted (does not affect this value): median and mean both equal the maximum 0.463 though range starts at 0.388; with Pi > 2 requiring > 0.4 mg/kg, category 5 probably holds one or very few samples, and the 0.388 lower bound is the band start, not an observed value.
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.
