Who / where / when / HowDiscoverer: recognized to old civilizationDiscovery Location: UnknownDiscovery Year: UnknownName Origin:From the Greek god Mercury that was the messenger come the gods and was well-known for his speed; Hg native mercury"s Latin surname Hydrargyrum, which comes from the Greek native "hydrargyros" ("hydor" for water and "argyros" because that silver).Abundance the Mercury:Earth"s Crust/p.p.m.: 0.05Seawater/p.p.m.: Atlantic Suface: 4.9E-07Atlantic Deep: 4.9E-07Pacific Surface: 3.3E-07Pacific Deep: 3.3E-07Atmosphere/p.p.m.: N/ASun (Relative to H=1E12): 125Sources of Mercury:Most mercury comes from cinnabar ore. Yearly world production is roughly 8,400 tons. Major mining areas are Spain, Italy, Yugoslavia.Uses the Mercury:Used in thermometers, barometers, fluorescent lamps and also batteries.Additional Notes:Causes neurological and also kidney damage and also blindness. Also associated with birth defects. Really damaging to aquatic life. That is uncovered in paint, batteries, thermometers, electrical equipment, fluorescent lights and also plastics. Also used in gold mining industry. Batteries account because that 88% that the mercury content in municipal heavy waste.
