HMI baseline position
Limited data: Reported as rank; a concentration reference in µg/kg cannot apply. Missing evidence never means low contamination.
Reported as rank; a concentration reference in µg/kg cannot apply.
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
2014
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Five southern Jiangsu areas
Sampling site within one study.
Sampling, analysis and reporting limits
Rice grain: 1.000 g digested with HClO4/HNO3 for 6 h; Cd and Zn by ICP-MS (XSERIES, Thermo). Bioaccessible Cd by RIVM in vitro digestion. Soil: HNO3/HClO4/HF total digestion; 0.01 M CaCl2 extraction.

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.
