The lack of precision offered by FDA with respect to the average exposure to mercury from dental amalgam, not to mention their total failure to dependably quantify the range of exposure including those maximally exposed and those younger than six years of age, is disconcerting. The FDA has failed to adequately quantify:
the full range of exposure across the entire population, in all relevant age groups;
the proportion of the amalgam-bearing population that exceed the US EPA RfC and the ATSDR MRL, the two reference exposure levels identified by the FDA as providing health protection to the non-occupationally exposed general population;
the exposure in children less than 6 years of age, an age group considered the most vulnerable to exposure and effects and a population group that does, indeed, receive amalgam fillings.
