Re-evaluation of The Hazardous Effect of The Superphosphate Factory By-products at Assiut Governorate on Goat Health

Abstract

Environmental pollution is one of the most deleterious agents to the biological life. Industrialization offered additional hazards to the environment surrounding man and animals. Grazing animals are often a reliable indicator of environmental pollution, either by food, water and air exposure, they receive contaminants which are transferred through the food chain to human being. Five water samples ,five feed stuff (wheat straw) samples and twenty goats selected from areas surrounding superphosphate factory (Gaz.El-Akrad, El-Twabiya, Manqabad and Ilwan areas), as well as from Dairut area as a control region. Blood and hair samples were taken from each chosen goat. Liver; kidney, lung, muscle and bone samples were taken from slaughtered goats. Water, feed stuff, hair, senun and animal organs were subjected to chemical analysis for determination of fluorine, sulphur and cadmium. Organs of the studied goats were subjected to histopathological examination. Blood samples were subjected to hematological examination (RBCs count, WBCs count, differential leucocytic count, hemoglobin concentration and PCV). Serum was used for the quantitative determination of fluorine, sulphur, cadmium, calcium , phosphorous as well as some biochemical parameters (ALT, AST, ALP, creatinine and urea). Examination of fluorine levels in water revealed that the highest concentrations of fluorine in water was at Gaz.El-Akrad, Ilwan and El- Twabiya, areas which reached 0.20 ± 0.022 , 0.19 ± 0.008 and 0.17 ± 0.006 mg/L respectively. All examined water samples were less than the permissible limit of fluorine in water (1ppm).
