Heavy metal contamination of poultry meat is a critical issue for human health due to associated risks of cytotoxicity and systemic pathologies after ingestion of such metals. A total of twenty chicken liver samples were collected from markets of Erbil city and analyzed for ten heavy metals contents by Inductively Coupled Plasma Optical Emission Spectrometry. The targeted metals were cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), mercury (Hg), zinc (Zn) and selenium (Se). The average concentrations (mg/kg) of targeted trace elements were 0.06±0.027, 0.06±0.05, 2.05±0.34, 1.85±0.47, 0.15±0.17, and 33.53±5.24 for Co, Cr, Cu, Mn, Ni, and Zn respectively. Copper (Cu) levels significantly exceeded the maximum permissible limit of WHO. Moreover, the average concentrations of toxic heavy metals and selenium were 0.07±0.037, 0.278±0.10, 0.11±0.083, and 2.01±0.454 mg/kg for Cd, Pb, Hg, and Se respectively. Hg and Pb levels exceeded the permissible limits of WHO. Higher levels of Cu and Hg in poultry may pose a serious threat to consumers which demand countermeasures and precautions to be taken. Iraqi Standards Authority and relevant official institutions are strongly recommended to regulate safe disposal of heavy metal waste in the environment to reduce animal exposure to such metals.
由于摄入此类金属后存在细胞毒性和全身性病理风险，禽肉中的重金属污染对人类健康而言是一个关键问题。从埃尔比勒市市场共采集了20份鸡肝样本，并通过电感耦合等离子体发射光谱法分析了其中10种重金属的含量。目标金属为镉（Cd）、钴（Co）、铬（Cr）、铜（Cu）、锰（Mn）、镍（Ni）、铅（Pb）、汞（Hg）、锌（Zn）和硒（Se）。目标微量元素的平均浓度（mg/kg）分别为：钴（Co）0.06±0.027、铬（Cr）0.06±0.05、铜（Cu）2.05±0.34、锰（Mn）0.15±0.17、镍（Ni）以及锌（Zn）33.53±5.24。铜（Cu）含量显著超过了世界卫生组织的最大允许限量。此外，有毒重金属和硒的平均浓度分别为：镉（Cd）0.07±0.037、铅（Pb）0.278±0.10、汞（Hg）0.11±0.083以及硒（Se）2.01±0.454 mg/kg。汞（Hg）和铅（Pb）含量超过了世界卫生组织的允许限量。家禽中较高水平的铜（Cu）和汞（Hg）可能对消费者构成严重威胁，这就需要采取应对措施和预防措施。强烈建议伊拉克标准管理局及相关官方机构规范环境中重金属废物的安全处置，以减少动物接触此类金属。
