Omirzakov et al. 2024 - Analysis of heavy metals content in domestic and imported poultry meat
This study measured arsenic, cadmium, mercury, and lead in domestic and imported poultry meat sampled in Kazakhstan using ICP-MS.
Key numbers
Source units are ug/kg unless otherwise noted.
- Regulatory comparison values cited by the authors: tAs 0.1 mg/kg, Cd 0.05 mg/kg, Hg 0.03 mg/kg, Pb 0.5 mg/kg.
- Cadmium ranged from 0.06 ug/kg in the lowest domestic producer sample to 2.45 ug/kg in the highest domestic producer sample; average Cd was 0.65 ug/kg in domestic poultry and 0.51 ug/kg in imported poultry.
- Mercury was detected in Astana market samples at 3.48 ug/kg, the highest domestic producer sample at 20.0 ug/kg, and imported products at 1.88 ug/kg; average Hg was 2.62 ug/kg domestic and 1.88 ug/kg imported.
- Lead ranged from 0.13 ug/kg in the lowest domestic producer sample to 123.8 ug/kg in the highest domestic producer sample; average Pb was 21.51 ug/kg domestic and 12 ug/kg imported.
- Average tAs was 5.28 ug/kg domestic and 5.59 ug/kg imported.
Methods
The authors report ICP-MS analysis against a linear dynamic range with blanks and interlaboratory quality-control support.
Implications
The source supports Kazakhstan poultry occurrence context. All averages are below the paper’s stated Customs Union maximum permissible levels, but the highest domestic producer sample is a notable high-lead/high-mercury point within the dataset.
