Rice finding 531
Source evidence and comparison details for the Rice profile.
Rice grain (form not stated; dried and powdered); sela (parboiled) rice · Cadmium (Cd) · 24 rice samples (24 per type); each digest analysed in triplicate.
Selected finding and reference
24 rice samples (24 per type); each digest analysed in triplicate. Basis: dry weight (oven-dried 65 °C; Table 2 does not state basis explicitly).
no non-detects reported; no LOD/LOQ 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
2016–2017
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Rice2 (n = 24), rice sela
Rice variety or type within one study.
Sampling, analysis and reporting limits
0.5 g dried sample digested in HNO3 then HClO4 at 90 °C; ICP-MS (Agilent 7500 CX) at Institute of Urban Environment, CAS Xiamen.
no non-detects reported; no LOD/LOQ reported
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.
