Boyd Haley P.h.D. discusses measuring mercury vapor released from amalgam fillings.
Boyd Haley discusses his study measuring how much mercury vapor is emitted from types of dental amalgam fillings.
The FDA cites an ill-defined and unsubstantiated estimate of absorbed mercury exposure from dental amalgam of 1 to 5 μgs/day that supposedly relates to the presence of between 7 and 10 amalgam fillings.
This conclusion is attributed to a report by the Public Health Service publishedin 1993 (PHS, 1993). This cited report did not contain or conduct a detailed quantification of mercury exposure but based its estimates on the review of other yet older reports.
Contrary to the FDA’s statement, the WHO Environmental Health Criteria 118 (WHO1991) did not “[find] that values generally in the range of 1-5 μg/day were estimated in theU.S. adult population”.
Contrary to FDA’s assertion, the WHO (2003) did not conclude that “the highest estimate that WHO reports was a dose of 12 μgs/day, for middle-aged individuals with approximately 30 amalgam surfaces (Ref. 22)”.
