Summary
Polish dietary study comparing additive-model-predicted vs. laboratory-measured concentrations of microelements and toxic elements including Sb in four dietary variants enriched with 4% beetroot (two cultivars, with and without selenium-based foliar application). The study found discrepancies between predicted and measured values, with Sb among the analytes showing discrepancies. This is a methodological study on dietary assessment accuracy rather than a food concentration survey.
Key numbers
Specific Sb concentration values in food matrices are reported per dietary variant in this paper. The study’s primary relevance for the wiki is methodological: food composition database values for Sb (and other toxic elements) can differ substantially from directly measured values, which affects reliability of dietary exposure estimates.
Analytical method: ICP-MS. Sample matrices: dietary components and complete diets containing beetroot supplements.
Evidence Fitness
Context only for a metal page. The paper documents that additive dietary models for Sb can diverge from measurement, relevant as a methodological caveat on dietary exposure estimates.
Methods (brief)
Four dietary variants (Boldor 1, Boldor 3, Wodan 1, Wodan 3) prepared from basal diet plus 4% beetroot at two cultivars and two selenium-treatment levels. Predicted values calculated using P = 0.96 x C(basal) + 0.04 x C(beetroot). Measured concentrations by ICP-MS. University of Warmia and Mazury, Poland.
Implications
- Certification: highlights that nominal dietary Sb estimates may differ from actual measured values.
- Courses: useful for teaching limitations of food composition databases for trace toxic elements.
- App: does not provide occurrence values usable in a contamination profile.
- Microbiome: not addressed.
