Dental amalgam -- Environmental aspects
Wastewater treatment
Abstract:In drinking water treatments, a form of chlorine is used for disinfection so that bacteria do not contaminate pipes. Most drinking water treatment plants use chlorine (HOCl/OCl-), but some have switched to monochloramine (NH2Cl). Although chlorine is a stronger germicide, monochloramine is more stable in water, and thus more effective, especially in large drinking water distribution systems. Another well-known trait of chlorine and monochloramine is their ability to mobilize mercury. ISTC partnered with researchers from the Naval Institute for Dental and Biomedical Research to see how chlorine and chloramine would affect the mobilization of mercury from dental amalgams in wastewater. Full results published in Stone, Mark E., et al (2009). "Comparison of chlorine and chloramine in the release of mercury from dental amalgam." Science of the Total Environment 407(2), 770-775.
