[Factors influencing fluorine absorption and excretion in people and animals].

Factors that make fluorine absorption and excretion easy or difficult from organisms of people and animals have been analysed. Fluorine is easily absorbed in presence of alimentary fat from soluble dust, from water environment, especially from an acid one. Compounds of calcium, magnesium, aluminium, microelements and various high protein diet make fluorine absorption difficult. Compounds that easily absorb fluorine, namely compounds of calcium, magnesium, aluminium, boron, phosphorus and vitamin C as well as climatic conditions (increasing perspiration) make fluorine excretion from organisms easy. Fluorine excretion is made difficult in the period of intensified mineralization and lactation processes. The age of the person is also important.
