title: Environmental hazard evaluation of amalgam scrap.
abstract: Amalgam scrap was subjected to two different Environmental Protection Agency (EPA) extraction procedures to determine if it presents an environmental hazard. The results indicate that concentrations of mercury and silver in the extracts do not exceed the EPA's maximum allowable concentrations. It was concluded that amalgam scrap is not a hazardous solid waste. Proper handling of amalgam scrap disposal by recycling is, however, highly recommended.
