FAN Bulletin 2012: New fluoride-lead study should end fluoridation
This very important new study has just been published, ahead of print, by the journal Toxicology, in February 2010:
Fluoride increases lead concentrations in whole blood and in calcified tissues from lead-exposed rats

The authors note that, "Higher blood lead levels have been reported in children living in communities that receive fluoride-treated water." They cite the two papers on Masters and Coplan (1999, 2000).

The authors designed an animal experiment to see whether fluoride co-administered with lead increases lead concentrations in blood and calcified tissues. It is important to note that the fluoride compound that they used was hexafluorosilicic acid, one of the silicon fluorides used as fluoridating agents in over 90% of the water supplies fluoridated in the US. Hitherto, nearly all animal experiments have used sodium fluoride.................................
