Abstract
An account is given of the occurrence in England of fluorosis in farm animals arising from industrial contamination of pasture due to the manufacture of bricks, the calcining of ironstone, and the fumes from a color and enamel factory. It is shown that the contamination of vegetation is entirely superficial and not due to fluorine compounds carried down into the soil by rain. The origin of the aerial fluorine is discussed in relation to the industrial processes involved, and extent of damage related to distance from source and direction of prevailing wind. A map showing levels of pasture contamination (7 ppm to 90 ppm) is given, and this is discussed in relation to the severity of clinical symptoms in animals. Considerable differences were observed in regard to susceptibility of different classes of stock. Urinary analysis was found to be a convenient way of diagnosing fluorosis, especially in sub-clinical cases where no dental signs or obvious skeletal changes were present. By correlating urinary excretion with fluorine values on rib bone removed surgically in an animal taken away from the source of fluorine ingestion, it was found that about half of the original skeletal fluorine still remained after eight months and that,
