Gholami-Ahangaran et al. 2021 - Cadmium, zinc, and silver in chicken meat
This study measured cadmium, zinc, and silver in chicken tissues sold in Isfahan Province, Iran. It is routeable for poultry occurrence evidence because it reports tissue-specific means in mg/kg.
Key numbers
- The study collected 100 chicken tissue samples from public meat markets.
- Mean cadmium concentrations were 0.055 +/- 0.021 mg/kg in thigh, 0.048 +/- 0.023 mg/kg in breast, 0.074 +/- 0.031 mg/kg in liver, and 0.012 +/- 0.004 mg/kg in heart.
- Mean zinc concentrations were 17.90 +/- 8.10 mg/kg in thigh, 15.70 +/- 5.75 mg/kg in breast, 22.10 +/- 10.87 mg/kg in liver, and 19.70 +/- 10.38 mg/kg in heart.
- Mean silver concentrations were 0.0080 +/- 0.0044 mg/kg in thigh, 0.0048 +/- 0.0013 mg/kg in breast, 0.036 +/- 0.006 mg/kg in liver, and 0.012 +/- 0.009 mg/kg in heart.
- The paper states that Cd and Zn were below international permissible limits in all samples.
- Cd in analyzed samples ranged from zero to 0.27 mg/kg.
Methods
Chicken tissues were digested and analyzed by atomic absorption spectrophotometry for Cd, Zn, and Ag.
Implications
The source supports poultry and organ-meat occurrence evidence for Cd and Zn in an Iranian retail-market setting. Silver is recorded as broader trace-element context.

Verification notes
The paper reports values by tissue type, so routing should distinguish muscle-meat context from liver/heart organ-meat context when downstream extraction supports that granularity. The abstract and results/table disagree for several Zn and Ag cells; this page follows the results narrative and Table 1 rather than the abstract.
