Rice finding 273
Source evidence and comparison details for the Rice profile.
Rice (쌀), edible portion homogenised; brown vs milled not stated · Total arsenic (tAs) · 40 rice samples (about 2 kg each) paired with soil from the same farm.
Selected finding and reference
40 rice samples (about 2 kg each) paired with soil from the same farm. Basis: fresh/as-collected edible portion (homogenised and frozen; no drying stated); unit mg/kg.
no non-detects indicated
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
2010–2011
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Korean farms, rice (all samples)
All samples in the study.
Sampling, analysis and reporting limits
HNO3/H2O2 microwave digestion (Milestone ETHOS, 200 C), ICP-MS (Agilent 7500a) at m/z 75, 111, 208.
no non-detects indicated
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.
