Clinico-toxicological study of environmental pollution of sulphur & fluorine in goats

Environmental pollution is one of the most deleterious agents to thebiological life. Industrialisation offered additional hazards to the environmentsurrounding man and animals.In Assiut provence the fertlizer manufacturing operation 1S one ofthe main sources contributed to air pollution. Air pollution takes placefrom the emmitted HF , SiF4 and 502 gasses.The present study aimed to evaluate the environmental fluorine andsulphur toxicity in the adult goats either pregnant or non-pregnant in additionto investigate the effects of the toxic hazards on the prenatal (foeti) andpost-natal (young) life of the goats.The study was carried out on 23 goats exposed to the toxic hazardsemitted in the vicinity of the superphosphate producing factory. The animalswere la adul t non-pregnant, 5 pregnant and 8 young goats. Ten foeti wereobtained from the pregnant exposed goats.On clinical examination, the animals showed general suggestive slgnsof intoxication In the form of emaciation, cachexia, loss of patches ofhair, dry and rough skin and abnormal gait and movement. Bone exostosiswas detected in all bone segments of the adul t exposed goats in additionto the dental changes. Young animals showed no dental changes, however,In few cases there were slight submandibular irregularities. The analysisof urine and rumen fluid indicated no abnormality in the physical characters.Bone segments showed variable changes either in radiographic assay ormacerated cleanded bone morphology. X-ray investigations revealed markedvar ia tions; increased bone density, thickening of compact bone layers,
