The Environmental Protection Agency (EPA) will eventually mandate that dentists nationwide install amalgam separators, which captures 99.5% of waste amalgam containing mercury before it hits the wastewater stream.
Two different methods used to measure mercury (Hg) vapor levels in the air exhausted from dental vacuum systems revealed that Hg vapor release to the atmosphere from dental vacuums can be substantial and exceed human exposure limits.
This study investigated residual mercury (Hg) determinations and toxicity characteristic leaching procedure (TCLP) analysis of used amalgam capsules. All capsules tested retained Hg. TCLP analysis of the triturated capsules showed Sybraloye and Contoure leached Hg at greater than the 0.2 mg/l Resource Conservation and Recovery Act (RCRA) limit.
Alex Cain of the EPA published a study in the Journal of Industrial Ecology that evaluated the substance flow analysis of dental mercury releases Into the environment. His comprehensive analysis revealed dentists releaase up to 24 tons of mercury into the environment, a level much more significant than previously thought, which warrants being addressed.
Oct. 11, 2011 The World Health Organization today released its 2009 meeting report on the "Future Use of Materials for Dental Restorations" in preparation for the third of five Intergovernmental Committee deliberations. The WHO report suggests, over time, the global "phase down" of amalgam.
Mercuryexposure.info was created and is maintained by consumers injured from exposure to mercury vapor and particles released by their dental amalgam fillings during placement, polishing, removal and day to day use. We are dedicated to providing accurate, up to date information on the many facets of dental mercury amalgam fillings.
