Effects of inorganic fluorides on animals
Fluoride toxicity in cattle can result from the ingestion of forage contaminated by various industrial processes. The disease is recognizable through its effects on the developing bones and teeth, by chemical analysis of urine and tissues and in advanced stages by definite physiologic disturbances. Definite effects on the well-being of cattle have been found to be associated with levels of fluoride in the compact bone in excess of 5500 ppm, and marginal bones of from 4500-5500 ppm. The concentration of fluoride on forage which would be needed to produce these concentrations in the skeleton would depend on a large number of factors. Air quality standards based on atmospheric fluoride levels do not seem feasible as a means of protecting livestock from possible damage. It does however appear that guidelines based on atmospheric fluoride levels or urinary fluoride content might serve to protect livestock in a community and be acceptable to fluoride emitting industries. 19 references, 6 figures, 1 table.
