摘要
研究总共筛选了168个肝脏，肾脏和肌肉（samples肌的一部分）样品。对样品进行制备，并使用原子吸收/火焰发射分光光度计测量铜（Cu）的水平。水牛器官的铜含量显示出变化。至于肝脏，平均铜浓度为11.52±5.41，湿重范围为2.34至21.88μg/ g。而在水牛肾脏中，铜含量从2.34到15.13不等，平均值为5.85±4.34μg/ g湿重。此外，水牛肌肉中铜的浓度从1.56微克/克湿重至15.50微克/克湿重，平均值为4.35±3.96。另一方面，牛肝中铜的浓度变化，平均值为11.59±5.79，湿重从3.13到25.00μg/ g不等。牛肾脏中的铜在2.50至16.3之间变化，平均值为4.18±3.12μg/ g湿重。此外，牛肌肉中铜的平均值分别为3.23±2.48、1.88和14.34μg/ g湿重。总之，牛和水牛的被检样品中有1％-26％高于埃及组织标准化与质量控制（2008）的结果，此外，肝脏样品中的铜含量高于肾脏和肌肉。

Abstract
A total of 168 samples of livers, kidneys and muscles (part of the diaphragm) were screened. The samples were subjected to preparation and for measurement the level of copper (Cu) by using Atomic Absorption/Flaming Emission Spectrophotometer. Buffaloes organs showed variations in their copper content. As for liver, the mean copper concentrations were 11.52 ± 5.41 with a range varied from 2.34 to 21.88 μg/g wet weight. Whereas in buffalo kidneys copper level varied from 2.34 to 15.13 with a mean value of 5.85 ± 4.34 μg/g wet weight. Moreover, the concentrations of copper in buffalo muscles varied from1.56 to 15.50 μg/g wet weight with a mean value of 4.35 ± 3.96. On the other hand, copper in cattle liver varied in its concentrations where the mean value was 11.59 ± 5.79, with a range varied from 3.13 to 25.00 μg/g wet weight. Copper in cattle kidneys varied from 2.50 to 16.3 with a mean value of 4.18 ± 3.12 μg/g wet weight. Besides, the concentrations of copper in cattle muscles were 3.23 ± 2.48, 1.88 and 14.34 μg/g wet weight, respectively as a mean, minimum and maximum. In conclusion, 1% - 26% of the examined samples of both cattle and buffalo were higher than the results obtained by Egyptian Organization Standardization and Quality Control (2008), in addition, livers samples have high concentrations of copper than kidneys and muscles.
