Rice finding 564
Source evidence and comparison details for the Rice profile.
Polished rice · Cadmium (Cd) · 5 rice samples (each analysed in triplicate).
Selected finding and reference
5 rice samples (each analysed in triplicate). Basis: dry weight (sun-dried, oven-dried 60 °C 2 days; paper refers to mg/kg dry weight).
No non-detects reported; analyte-specific LOD/LOQ only in Table S2 (not in text copy); overall LOD 0.09-35.75 µg/kg, LOQ 0.023-42 µg/kg
Low / Moderate / High rating
Direct comparison only: the reported summaries or non-overlapping reporting bounds establish the displayed descriptive direction, but do not supply an eligible reference distribution for Low / Moderate / High. A reporting bound remains a bound; equal rounded summaries do not establish equivalence.
Selected comparison
Lower6 versus 21 µg/kgJek Chuey Sao Hai rice: 6 µg/kg (mean ± 4 SD); brown rice (Pka Am Pun rice (Surin province)): 21 µg/kg (mean ± 17 SD).

Same source, analyte, statistic, basis and analytical method. Subgroups can share samples with the study total. A descriptive difference, not a significance test, treatment effect or safety judgment.Collection period

Geographic scope
Jek Chuey Sao Hai rice
Rice variety or type within one study.
Sampling, analysis and reporting limits
Microwave digestion (HNO3/H2O2, 160 °C) and ICP-MS (Agilent 7900); total As only.
No non-detects reported; analyte-specific LOD/LOQ only in Table S2 (not in text copy); overall LOD 0.09-35.75 µg/kg, LOQ 0.023-42 µg/kg
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.
