MANDIBULAR BONE FLUORIDE ACCUMULATION IN WILD RED DEER (CERVUS-ELAPHUS L) OF KNOWN AGE

Mandibular bone fluoride concentration and its relation to age were st udied in a sample of 39 red deer of known age (between 2 and 18 years) from an area not exposed to increased fluoride deposition (Hart mount ains, Germany). Bone fluoride level ranged from 208 to 1026 ppm dry we ight and was positively correlated with age (r=0.808, P<0.001), the ra te of skeletal fluoride accumulation being higher in younger individua ls, This indicates that during the period of skeletal growth, fluoride uptake is more rapid than in later life when accumulation at a lower rate occurs during normal bone turnover. Bone fluoride levels found in the present sample are regarded as resulting from ''normal'' fluoride exposure in a recent central European red deer population.
