In 2014, after the FAN conference held in DC in September, Chris Neurath (FAN’s science director), Quanyong Xiang (author of one of the most important IQ studies from China), Paul Connett and myself, presented this information (including the results of a detailed risk assessment) to current Office of Water officials and received an encouraging response.
It remains to be seen whether EPA will
take this opportunity to finally live up to its Principles of Scientific
Integrity and fulfill its mission of protecting public health. This will involve
admitting that their choice of severe dental fluorosis as the most sensitive end
point of fluoride’s toxicity in their determination of a new MCLG [Maximum
Contaminant Level Goal] for fluoride is just not tenable. Let’s be clear about
this, in several of the Chinese studies many children with lowered IQ have
exhibited milder categories of dental fluorosis, then the severe form chosen by
the EPA. This must make the lowering of IQ a more sensitive end point
than severe dental fluorosis.
If the EPA has the integrity to admit
this, good on them. If not, they should be prepared for a fight to the finish
from independent scientists and citizen fluoride fighters alike. We cannot
afford to lose the battle for integrity.
