Introduction
The interest in environmental mutagenesis has strengthened considerably following understanding of the broad overlap between mutagens and carcinogens. Also alterations in environmental mutagenicity lead to increases in the mutability of living organisms. Little however is known concerning mutagenic effects of gaseous fluoride, in particular fluorine containing emissions from industrial plants.
Previous studies have shown that grain crops in areas surrounding fluoride emitting
The recent paper by Einhorn et al. [1] drew the conclusion that fluoride incorporation into bone does not impair bone's mechanical properties. This result is in conflict with the results of others concerning fluoride and bone strength. For instance, several investigators--including ourselves--have shown that bone strength decreases as bone fluoride levels in the mineral phase increase to beyond about 4500 ppm [2-7]. When the fluoride content in the mineral phase reaches 10,000 ppm, bone strength
