Radad K*, Marwah A, Sary KA, Youssef MS Pathology in goats associated with super-phosphate emissions, Online J Vet Res 11 (1 : 10-19, 2007.. Patho-morphological changes in goats located near the production of phosphate fertilizer were evaluated. Cadmium in blood, liver, kidneys, lungs and heart of exposed goats increased compared with animals not exposed to emissions. Hepatic tissue revealed vacuolar and fatty degeneration with fibrosis whereas renal tissue showed glomerular swelling and periglomerular fibrosis, necrobiotic changes of the tubular epithelial cells and increased fibroblastic and lymphocytic activation in the interstitium. Pulmonary lesions included alveolar emphysema, thickening of alveolar septa and interstitial pneumonia. The heart revealed myocardial necrosis and fibrosis. In brain tissue there was neuronal degeneration and activation of glial cells. These changes were attributed to vascular damage associated with high levels of blood cadmium due to superphosphate exposure.
