Rice finding 490

Source evidence and comparison details for the Rice profile.

Rajkowska-Myśliwiec et al. 2024

White rice (polished; includes parboiled products RLe and RA) · Total arsenic (tAs) · 30 retail product packages (5 per manufacturer, 6 manufacturers per product group); 60 rice grain packages in scope.

Selected finding and reference

104 µg/kg (mean ± 19.6 SD)Mean.

30 retail product packages (5 per manufacturer, 6 manufacturers per product group); 60 rice grain packages in scope. Basis: unspecified (retail product as purchased, homogenised; no dry/fresh basis stated).

All results above the LOD (minimum values 69.5 and 87.6 µg/kg vs LOD 0.3 µg/kg); no non-detects reported.

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.

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.

Rice variety or type within one study.

Sampling, analysis and reporting limits

Microwave digestion (HNO3, CEM MDS-2000) then hydride generation ICP-AES/OES (Jobin Yvon JY-24) for total arsenic.

All results above the LOD (minimum values 69.5 and 87.6 µg/kg vs LOD 0.3 µg/kg); no non-detects 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.
