Abstract
Summary
Aluminum is present all around us as well as occurring naturally in feed, water, constituent of soil, plants, various medical drugs and animal tissues. Aluminum toxicity can occur in certain specific situations. When aluminum accumulates in the body, it can result in organ dysfunction and serious health problems.
The aim of this work was to estimate the level of aluminum in different compartments of the macro and micro environment of cattle in Upper Egypt (Assuit, Sohag and Naga Hamady) areas. For this purpose, concentrations of aluminum were measured in25 samples from both bran, mixed feedstuffs, water and cattle brain collected from cattle farms in Assuit, Sohag and Naga hamady areas.
The samples were digested and analyzed by graphite furnace atomic absorption spectrometric (GAAS) in the Central Laboratory of the Faculty of the Veterinary Medicine, Assiut University
The results of the examined samples (bran, feedstuff, drinking water and cattle’s brains) in Assiut were 0.126 ± 0.074, 0.091 ± 0.056, 0.036 ± 0.014 and 0.648 ± 0.64 ppm respectively. In Sohag governate were 0.318 ± 0.163, 0.102 ± 0.067, 0.064 ± 0.047 and 4.794 ± 1.942 ppm respectively but in Naga Hamady were 1.868 ± 0.925, 1.688 ± 0.923, 0.942 ± 0.125 and 5.014 ± 1.738 ppm respectively.
Aluminum levels in bran, mixed feedstuff and water samples collected from Naga Hamady farms were significantly higher than the recommended national and international permissible limit. Also, aluminum level in brain samples collected from Naga Hamady was significantly higher than that in Assuit and Sohag. These high levels may be explained by the presence of Naga Hamady aluminium industry.
Aluminum is a cumulative metal which is indicated by a direct correlation between aluminum levels in the animal’s brain and age of animals in the present study.
Finally, we recommend that:
Restriction of Al containing fumigants in the field.
Application of ecological evaluation of factories before construction
