Overview
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.
