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.
对汞合金废料进行了两种不同的美国环境保护局(EPA)提取程序,以确定其是否存在环境危害。结果表明,提取物中汞和银的浓度未超过EPA的最大允许浓度。得出的结论是,汞合金废料不是危险固体废物。不过,强烈建议通过回收妥善处理汞合金废料的处置。
