Equipment with Mercury

Examples of Biomedical Equipment that
may contain Mercury and Alternative Equipment

Items were included on the following lists because they have been reported to contain mercury as an intentional ingredient or component, or as an unintended contaminant. The listings were compiled from multiple sources and were believed to be accurate at the time of posting on this web site. However, users should understand that this information is provided for guidance only and the mercury content of commercial products may be subject to frequent change. Consult with manufacturers and other reputable sources of information, or conduct analyses of products to confirm mercury concentrations. Users should also confirm that alternative products meet all applicable regulatory, protocol and performance requirements before being used in biomedical applications.

DENTAL AMALGAMS (Capsules and waste)
*From strictly an environmental standpoint, mercury-free alternatives to amalgams are favored. However, amalgams offer durability and other advantages in dental restorations. No valid scientific evidence has been shown that amalgams cause harm to patients with dental restorations (fillings). Refer to the February 2002 Consumer Update by the Food and Drug Administration on the safety of dental amalgams. http://www.fda.gov/cdrh/consumer/amalgams.html

Information on current research funded by the National Institute of Dental and Craniofacial Research (NIDCR) on the health effects of dental amalgams in children may be found at this link http://www.nidcr.nih.gov/news/b2.htm
