Under certain conditions, chronic fluorosis in animals has been attributed to air-borne fluorides released into the atmosphere by factories. An investigation is described in which cattle, kept on a farm in the vicinity of a plant in which rock phosphate was being processed, developed clinical fluorosis, according to the classical descriptions of this disease of cattle. The concentrations of fluoride in the atmosphere overlying the farm, in samples of vegetation grown on the farm, and in the tissues of certain of the cattle kept on the farm were determined.
