SIGNS AND SYMPTOMS OF EXPOSURE
Symptoms of fluoride overexposure may include salivation,
nausea, vomiting, abdominal pain, fever, and labored breathing.
Fluoride ion can reduce serum calcium levels possibly causing
fatal hypocalcemia. Prolonged exposure to fluoride dusts,
vapors, or mists results in perforation of the nasal septum.
Chronic effects include excessive calcification of the bones,
ligaments, and tendons. Material is extremely destructive to
tissue of the mucous membranes and upper respiratory tract,
eyes, and skin. Inhalation may result in spasm, inflammation and
edema of the larynxand bronchi, chemical pneumonitis, and
pulmonary edema. Symptoms of exposure may include burning
sensation, coughing, wheezing, laryngitis, shortness of breath,
