20 volunteers were given 0.71 of water per day over a period of 10 weeks. Three different types of water were used--with traces of fluoride, with about 0.5 mg/1 fluoride and with about 11 mg/1 fluoride. A highly significant correlation was found between the intake of fluoride with the water and its elimination with the urine. About 50% of the fluoride taken in was eliminated on the same day.
