Fluorinations fluoride

Fluorine. Fluoride is present in the bones and teeth in very small quantities. Human ingestion is from 0.7—3.4 mg/d from food and water. Evidence for the essentiaUty of fluorine was obtained by maintaining rats on a duoride-free diet, resulting in decreased growth rate, decreased fertihty, and anemia. These impairments were remedied by supplementing the diets with duoride (81). Similar effects have been reported in goats (82). 

Details of both these methods as used by us are given below in specimen analyses. With regard to the bomb method, the lead washer supplied by the manufacturers was useless the lead melted and disintegrated at the temperature of the reaction. Copper was also found to be attacked and was otherwise unsatisfactory. Gold, on the other hand, was found to be most suitable. It is soft, will withstand the required temperature without melting or disintegrating, and is not attacked by fluorine, fluoride or alkali. 

Fluorine. Fluoride is present in the bones and teeth in very small quantities, Human ingestion is from II.7-1.J mg/d from food and water. 

We can anticipate that the forthcoming volumes of the series will deal with fluorine fluoride products in medicine and health. 

As a consequence of the monovalence of fluorine, fluorides at the high oxidation-state limit are often at, or near, the coordination limit for that element,... 

DOT CLASSIFICATION 2.3 Label Poison Gas, Oxidizer, Corrosive SAFETY PROFILE Poison by inhaladon. A corrosive material. Vigorous reacdon in contact with water or anhydrous nitric acid. Violent reacdon on contact with metals. When heated to decomposidon it emits very toxic fumes of CL and F . See also CHLORINE, FLUORINE, FLUORIDES, and CHLORINE TRIFLUORIDE.

Methoxyflurane metabolism produces inorganic fluorine, fluoride and oxalic acid. These are excreted through the urine and may cause renal damage. 

Mineral waters with a concentration of fluorides more than 2.0 mg 1 are called fluorine (fluoride) waters.
