Elemental mercury is well documented as a toxic, environmentally persistent substance that is atmospherically transported on a local, regional, and global scale. In addition, mercury can be environmentally transformed into methylmercury which bioaccumulates, biomagnifies, and is highly toxic.
EPA conducted a preliminary analysis of the costs, advantages, and disadvantages associated with mercury-free alternatives to certain mercury-containing products, and made a preliminary judgment that effective and economically feasible alternatives exist. These mercury-containing products include switches, relays/contactors, flame sensors, and button cell batteries. Therefore, EPA is evaluating whether an action (or combination of actions) under the Toxic Substances Control Act (TSCA) is appropriate for mercury used in such products. As appropriate, such an action(s) would involve a group(s) of these products. Specifically, EPA will determine whether the continued use of mercury in one or more of these products would pose an unreasonable risk to human health and the environment.
