 Mercury (element) - Wikipedia, the free encyclopedia
Mercury is used in thermometers, barometers and other scientific apparatuses, although the use of mercury in thermometers has been largely phased out in clinical and scientific environments (in favor of alcohol-filled, digital or thermistor-based replacements) in the interests of health and safety due to the toxicity of the element.
Mercury is still used in some cultures for folk medicine and ceremonial purposes which may involve ingestion, injection, or the sprinkling of elemental mercury around the home.
Environmental releases and disposal of mercury is regulated in the U.S. primarily by the EPA.

 Mercury
The most important salts are mercury chloride (corrosive sublimate - a violent poison), mercurous chloride (calomel, occasionally still used in medicine), mercury fulminate, a detonator widely used in explosives, and mercuric sulfide (vermillion, a high-grade paint pigment).
Mercury is a virulent poison and is readily absorbed through the respiratory tract, the gastrointestinal tract, or through unbroken skin.

 Mercury fulminate - Wikipedia, the free encyclopedia
Today mercury fulminate tends to be replaced by other primary explosives which are less toxic and more stable in time: lead azide, lead styphnate and tetrazene derivatives.
It can be prepared by mixing alcohol (18 parts) with a solution prepared by action of concentrated nitric acid (60 parts) on mercury (1 part).
Silver fulminate can be prepared in a similar way, but this salt is even more violent than mercury fulminate.
