A field investigation was conducted to determine the possible presence and severity of cattle fluorosis near an alumina reduction works in which fluoride effluent collection equipment had been in operation for one year. Physical examinations of cattle, periodic analyses of feed and urine, and analyses of animal tissues disclosed a low rate of intake, excretion, and storage of fluoride by cattle within the suspect area. Analysis of bovine urine samples obtained in 15 rural areas disclosed an average urinary fluoride concentration of 2.7 p.p.m. with 1.2% of the samples above 8 p.p.m. In the suspect area the average urinary fluoride was 4.5 p.p.m. with 1.7% of the samples above 12 p.p.m. Bone fluoride concentrations averaged 437 p.p.m. in the control areas and 470 p.p.m. in the suspect area. Analyses of teeth obtained in control areas had an average of 284 p.p.m. fluoride and those from the suspect area averaged 362 p.p.m. fluoride. Determination of urinary fluoride levels is suggested as presumptive or preliminary criteria for diagnosis of bovine fluorosis. Such analyses should be supplemented with a careful physical examination of the teeth and bones to establish evidence of past damage and intake as well as chemical analyses of forage, feed concentrates, and water to determine the source of the fluoride. Analyses of cattle bones are also helpful in establishing past intake. 16 references, 1 figure, 1 table.
