Concentrations of Manganese in Edible Tissues of Slaughtered Animals in upper Egypt

A total of 168 samples of livers, kidneys and muscles (part of the diaphragm) were screened. The samples were subjected to preparation & for measurement the level of copper by using Atomic Absorption/Flaming Emission Spectrophotometer. Buffaloes organs showed variations in their manganese content.Results revealed that manganese concentrations in buffalo livers were 3.82 0.61 as a mean where the levels varied from 2.85 to 5.36 μg/g wet weight. In kidneys of buffalo the minimum, maximum and mean values were 1.50, 4.47 and 2.96  0.71 μg/g wet weight, respectively. Moreover, the mean concentrations of manganese in muscles of buffalo was 1.85  0.52, with a minimum of 0.89 and a maximum of 2.68 μg/g wet weight. On the other hand, for cattle, mean  standard deviation and range of manganese concentrations in livers were 4.54  2.51 and 2.14-14.14 μg/g wet weight, respectively. While the corresponding values in kidneys were 3.07  2.47 and 0.89 -13.57 μg/g wet weight. Moreover, the mean concentrations of manganese in muscles of cattle was 3.11  5.5 with a minimum of 0.89 and a maximum of 28.57 μg/g wet weight. In conclusion, livers samples have high concentrations of manganese than kidneys and muscles.
