Abstract
Blood serum analysis comprised the estimation of copper,
molybdenum, calcium, inorganic phos~hnrus and alkaline phosphatase activity. Fluoride level(ppm) was determined in bone ash. The bone samples from animals at the affected areas as well as the control ones were chosen from metacarpal, metatarcal,ribs and mandible. Serum levels of fluoride and sulphur were significantly elevated in animals at areas less than 2.5 km. far away from the factory while insignificant elevation was recorded in other areas. Bone fluoride was also generally elevated in affected animals and reached 5 times the values of the control. Haematological investigations revealed that there were decreased values of totql RBC, Hb, PCV., MCH and f,[HC associated with elevated values of MCV. in animals with high levels of serum fluoride and sulphur. Non significant v8riation was observed in total leukocytic
count while lymphocytosis, neutropenia and monocytopenia
were recorded in most diseased cases. Blood serum analysis showed that serum copper level was significantly decreased in all the affected camels at areas up to 4 km. from the factory. Serum molybdenum levels was also elevated in areas nearer to the factory. Serum calcium and serum inorganic phosphorus levels were not affected and remained within normal physiological range. Alkaline phosphatase activity was increased in the area adjacent to the factory where sulphur and fluorine were very high and in the area of El-Walidyia where copper was greatly decreased. The present study revealed that camels were affected by fluoride and sulphur compounds in the polluted areas and showed the signs of intoxication. Finally it is important to prevent or even minimize environmental pollution by sulphur and fluoride compounds to protect the animal health and production.
