Increased fluoride content in mandibular bones of deer living in industrialised regions of Poland.

Fluorine is a microelement appearing in soil, water and living organisms. Higher fluorine concentration exerts a negative effect on the course of metabolic processes, mainly in the bones. The studies performed have shown that in areas polluted by industrial emissions the fluoride level in bones of animals rises, but fails to reach concentrations characteristic of the disease called bone fluorosis. The results presented illustrate the quantity being reached by fluoride accumulation in the bones of animals from areas polluted by industrial emissions.
