Chemical Found In: Mercury (Hg) is a heavy chemical element that is emitted to the air by human activities, such as manufacturing or burning coal for fuel, and from natural sources, such as volcanoes. It is deposited, via ecosystem transport, into lakes and oceans, where it bioaccumulates in fish. According to the US EPA, "nearly all methylmercury exposures in the U.S. occur through eating fish and shellfish." In addition, mercury is used in thermometers, barometers, float valves, mercury switches, and other devices where exposure can occur with device breakage. It is also found in amalgam material for dental restorations, energyefficient light bulbs, and is used in scientific research applications.
