This study aimed to evaluate the mean concentration of cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), and lead (Pb) in the meat and offal of cow and sheep. Also, the estimated daily intake (EDI) and health risk of these metals were calculated. Analysis of metals was undertaken by the use of an inductively coupled plasma-optic emission spectroscopy (ICP-OES). All samples were contaminated with all metals. Principal component analysis (PCA) showed a clear differentiation of cow and sheep in both the kidney and liver samples. In the liver and kidney, level of Cd, Cu, and Pb were positively correlated. The highest target hazard quotients (THQs) were calculated for Pb. Cd level in cow kidney had the highest carcinogenic rate (CR). Although, hazard index (HI) was lower than one, consumption of muscle especially in children should be noticed in both national and international consumers due to higher level of HI.
本研究旨在评估牛和羊的肉和内脏中镉（Cd）、铬（Cr）、铜（Cu）、镍（Ni）和铅（Pb）的平均浓度。此外，还计算了这些金属的估计每日摄入量（EDI）和健康风险。金属分析采用电感耦合等离子体发射光谱法（ICP-OES）进行。所有样品均受到所有金属的污染。主成分分析（PCA）显示，牛和羊在肾脏和肝脏样本中均有明显区分。在肝脏和肾脏中，Cd、Cu 和 Pb 的水平呈正相关。最高的目标危害系数（THQ）是针对 Pb 计算的。牛肾中的 Cd 含量具有最高的致癌率（CR）。尽管危害指数（HI）低于 1，但由于 HI 较高，国内和国际消费者均应注意肌肉的消费，特别是儿童。
