Comment:

The researchers conclude, "Mercury in dental amalgam is a significant environmental concern and requires better management. Dentistry contributes almost 1,900 kg of Hg per year to the Canadian environment."

Abstract / Excerpt:

“Dental amalgam is 50% mercury (Hg) by weight and its continued use as the preferred dental restorative material in Canada constitutes a significant source of Hg to municipal sewers and ultimately to the environment. The Recent CCME Canada Wide Standard on Hg for Dental Amalgam Waste provides a national basis for managing the Hg-containing wastes from dental clinics and ultimately reducing what is currently considered to be the single largest source of Hg to municipal sewers. This paper briefly reviews the background and rationale that lead to the need for and ratification of that Canada Wide Standard.”
