Bazzaz et al. 2023 - Determination of some heavy metals resides in different types of poultry production
This study measured copper, total arsenic, and lead in poultry products consumed in Erbil, Iraq, including imported Brazilian and Turkish chicken, local-company chicken, local quail meat, and quail eggs.
Key numbers
Source units are mg/kg.
- Chicken thigh: Brazilian-origin samples had Cu 1.57 +/- 0.04, tAs 1.82 +/- 0.06, and Pb 0.55 +/- 0.05. Turkish-origin samples had Cu 1.53 +/- 0.05, tAs 1.57 +/- 0.03, and Pb 0.43 +/- 0.04.
- Chicken breast: Brazilian-origin samples had Cu 1.67 +/- 0.03, tAs 1.82 +/- 0.07, and Pb 0.50 +/- 0.03. Turkish-origin samples had Cu 1.65 +/- 0.04, tAs 1.77 +/- 0.04, and Pb 0.49 +/- 0.03.
- The source’s stated international permissible limits in the table are Cu 200 mg/kg, tAs 2 mg/kg, and Pb 0.5-1.0 mg/kg.
- The authors report Brazilian chicken thigh and breast Pb as high relative to other poultry and above the stated permissible level comparison.
Methods
The paper reports heavy-metal residue determination in poultry products, with statistical comparisons across origin/product groups. Arsenic is reported as total arsenic; no arsenic speciation is provided.
Implications
The source supports poultry product occurrence routing for Erbil market/import contexts. Brazilian-origin chicken Pb sits at the lower edge or just above the paper’s comparison range depending on cut, so route with the origin and cut preserved.

Verification notes
- Source identity checked against DOI 10.25130/tjas.23.2.17 and the downloaded PDF.
- The title contains a source typo (“resides” for residues); the page title preserves the source wording in frontmatter.
