Abstract:Dental amalgam consists of approximately equal parts mixture of metallic mercury and an alloy powder consisting of silver, tin, copper and zinc. Amalgam has been used extensively as a tooth filling material, accounting for 75% of posterior restorations. The waste material from dental offices generated during restorative dental procedures contains amalgam. The uncontrolled discharge of this waste into the sewer system from a large number of dental units (i.e. dental clinics), will increase the mercury load to treatment facilities and could eventually contribute higher potential mercury exposure as well. The main objective of this project was to characterize the properties of the dental waste (DW) stream.
