Description
Summary:In certain industrial areas fluorides are present in various amounts in the atmosphere. These fluorides are liberated by industrial processes at high temperature in treatment of materials containing fluoride, either as a natural impurity, or as added material for technical purposes. Equipment and procedures have been installed in many plants to reduce the output of fluorides significantly, yet forage and hay grown near the plants may contain elevated amounts of fluorides. The feeding of such material to young livestock for many months may cause fluorosis or chronic fluoride poisoning. Some springs contain a high concentration of fluorides and the continuous use of this water as drinking water by animals may cause fluorosis also.
