It is also commonly known bytwo other terms: hydrargyrum and quicksilver. Of all metals, mercury is theonly one that, at standard temperature conditions and pressure, is liquid.3. Mercury was actuallythought to prolong life by the ancient Chinese and Tibetans. They also believedthis element could be used to maintain good health and heal fractures. However,a former emperor of China died after drinking a mixture of powdered jade andmercury.4. In ancient Greece, mercurywas used in ointments and cosmetics, the latter of which often resulted infacial deformities.5. Mercury is a very rareelement, having a presence of just 0.08 ppm (parts per million) in the Earthscrust. Yet, because mercury doesnt geochemically blend with the elements thatrepresent the larger crustal mass, its ores are often very concentrated. Infact, many of this elements ores are can be as much as 2.5% mercury.6. Mercury can be found ineither native metal form or within other minerals, such as cordierite, cinnabarand livingstonite.7. Most currently, theprimary uses of mercury are realized during the manufacturing of electricalapplications and industrial chemicals. However, there are countlessapplications that mercury is used in.8. Surprisingly, mercuryis present in several areas of medicine, including being present in variousdental amalgams, in certain vaccines to preserve them, in topical antisepticsand in diuretics, laxatives, diaper rash creams and ointments, nasal sprays,eye drops and, of course, it is still used in thermometers.9.

Mercury is considered to beextremely toxic, capable of causing both acute and chronic poisoning, andshould be handled with great care. Because of this, it is important to be awareof clean up procedures in the event of a mercury spill (or a broken thermometercontaining mercury). Do not use a broom or vacuum to clean up mercury; thiswill only disperse it further. Instead, attempt to merge the droplets into alarge pool and then use an eyedropper to remove the mercury to a securelocation. Once this has been done, you will need to spread powdered zinc orsulfur onto the spill area, collect this and dispose of it per the requirementsin your city or state. If mercury is spilled on clothing, it should be removedand discarded according to the same state or city regulations.
