Abstract
The fluorine conc. of the teeth and bones of cattle exposed to factory waste gases containing F was detd. The method of Kraft and May was used. (Hoppe-Seyler''s Zeitschr. Physiol. Chem., 246: 233, 1937.) Treatment of the teeth with alcohol or the bones with H2O decreased the F content. The normal F content for the teeth of cattle was about 0.0443% for the fresh material. In F poisoning this value was 5-10 times as great, and the conc. of F in the bones was also increased. The teeth of persons living near the factories also were affected. Specimens of Diluvial teeth obtained from a museum contained more F than those of modern animals.
