Koncentrace fluoridu v mateřském mlécea v moči u kojících žen v Praze 1997–1998

Concentrations of Fluoridesin Breast Milk and Urine in Nursing Mothers in Prague 1997–1998

Summary:
Concentrations of fluorides in samples of breast milk and urine were determinedin a group of nursing mothers living in Prague in 1997–1998. Fluoride level in breast milk wastraced as a natural source of fluorides in the infants nutrition. The excretion of fluorides inurine was ascertained as the reflection of the mother’s fluoride intake. The mean concentrationof fluoride in breast milk amounted to 0.10 ppm F while the one in urine was twice as high.The breast milk fluoride levels correlated well with those in urine. It can be stated, that thebreast milk as a sole source of fluorides in infant’s nutrition is deficite and in the period of fullnursing some fluoride supplementation is fully indicated.
