The hazards of fluoride (16984488) exposure were studied in southern Morocco. The areas selected were zones of phosphate mining and factories that process phosphoric-acid (7664382) fertilizers (SIC-2874). Three farms were randomly selected from each of 15 villages. Samples from water tanks, grass, straw, barley, and corn forage were collected; samples from unpolluted areas served as controls. Fluoride content of the samples was measured by a digital pH meter fitted with an ion selective electrode. Clinical examination was performed on 10 percent of the exposed animals to test for clinical, bone, and dental abnormalities. Concentrations of fluoride measured in the northeast region were 430 to 4300 parts per million (ppm) in grass, 60 to 155ppm in straw, 19 to 22ppm in barley, 350 to 650ppm in corn forage, and 1.9ppm in water. Concentrations of fluoride in these samples were much lower in the east and southeast areas. Severe dental fluorosis occurred in several animals particularly in cattle and sheep; camels showed a much higher degree of lesion severity to fluoride pollution. Corn in the fluoride polluted area accumulated 2 to 6 times more the concentrations of fluoride than wheat or barley when compared with respective control values. The authors conclude that industrial fluoride pollution exists in southern Morocco.
