Overview
This study measured total arsenic in calf, chicken, and turkey meat samples using hydride-generation atomic fluorescence spectrometry. It is routeable for poultry and beef/calf meat occurrence evidence because it reports species-specific arsenic means in ng/g.
Key numbers
- Thirty-one meat samples were analyzed.
- Average total arsenic in calf meat was 12.1 +/- 3.9 ng/g.
- Average total arsenic in turkey meat was 3.1 +/- 1.2 ng/g.
- Average total arsenic in chicken meat was 2.8 +/- 1.1 ng/g.
- The method LOD was 0.3 ng/g.
- The authors report that daily arsenic intake via calf meat was almost two times higher than via poultry meat under their intake assumptions.
Methods
Samples were digested with concentrated nitric, perchloric, and sulfuric acids. Total arsenic was measured by hydride-generation atomic fluorescence spectrometry, with CRM DOLT-3 Dogfish Liver used for accuracy checks.
Implications
The source supports total arsenic occurrence evidence for poultry and calf meat. It does not speciate inorganic arsenic, so it must not be routed as iAs evidence.

Verification notes
The paper discusses inorganic arsenic toxicology in the introduction, but the measured endpoint is total arsenic.
