Nail and bone surface as biomarkers for acute fluoride exposure in rats.

May-June 2004 | Journal of Analytical Toxicology | Buzalaf MA, Caroselli EE, Cardoso de Oliveira R, Granjeiro JM, Whitford GM. | 8(4):249-52.
Finally, in our 48-h study, we found that bone surface fluo- ride concentrations increased sooner than those in the nails and that they did not decline as they did in nails. This suggests that fluoride accumulation on the periosteal surface of the femur is faster and less likely to change as a function of time. For these reasons, we believe that this region of the femur is probably a better biomarker to confirm exposure to large doses of fluoride.
