Rice finding 1768
Source evidence and comparison details for the Rice profile.
Polished white rice · Nickel (Ni) · 120 rice samples from farmer houses at 25 sites in 5 townships.
Selected finding and reference
120 rice samples from farmer houses at 25 sites in 5 townships. Basis: dry weight.
Minimum is a quantified value.
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
2017
No year-by-year sample register is reconstructed from this summary.
Geographic scope
Yangon region white rice
Reported growing area.
Sampling, analysis and reporting limits
HNO3 + H2O2 closed-vial digestion at 80 C for 12 h (30 mg in 30 mL); Agilent 8800 ICP-QQQ, As in O2 mass-shift mode (m/z 75 to 91), other elements in He collision mode.
Minimum is a quantified 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.
