FLUORINE BALANCE AND FLUORINE EMISSION FROM CEMENT KILNS

IN THE BURINING OF PORTLAND CEMENT CLINKER THE FLUORINE IS PARTLY DRIVEN OUT OF THE RAW MATERIAL AND FUEL. IN ORDER TO ELUCIDATE THE QUESTION WHETHER THE FLUORINE IS EMITTED IN GASEOUS FORM WITH THE KILN EXIT GASES OR IS COMBINED IN SOLID FORM IN THE CLINKER OR IN THE DUST, COMPLETE FLUORINE BALANCES FOR […]

Fluorides for Adults

Virtually all U.S. dentists now agree that the best way to prevent tooth decay is to fluoridate water supplies so that children get the benefits from the time their tooth buds begin to form—only a few weeks after conception. Failing that, many dentists paint stronger fluoride solutions on children’s teeth once or twice a year. […]

Antigo: Back to Fluorides

In 1949, Antigo, Wis. (present pop. 9,600), became one of the first communities in that state to put fluorides into its water supply in an effort to cut down tooth decay. But anti-fluoridation groups kept up a vigorous campaign, claiming that fluoride, a poison when taken in large doses, had cumulative toxic effects even when […]

Spectrophotometric determination of fluosilicic acid in hydrofluoric acid

Abstract: A procedure is reported for the spectrophotometric determination of fluosilicic acid in commercial hydrofluoric acid. The determination of silicon as (?)a-silicomolybdic acid is carried out directly without previous separation of hydrofluoric acid. Title of Study: Studies in the spectrophotometric determination of silicon in materials decomposed by hydrofluoric acid: Spectrophotometric determination of fluosilicic acid in […]

Fluoridated Water Criticized as Socialized Medicine

“Many people, particularly scientists, believe that we are suffering in the U.S. from a national epidemic of irrationality—what Senator J.W. Fulbright of Arkansas has called the ‘swinish blight of anti-intellectualism.’ Fluoridation of public water supplies has been recommended by an impressive list of scientific organizations. However, from the beginning there has been opposition. The anti-fluoridation […]
