Elemental mercury, a silver-white metal, is also known
‘quicksilver’ or ‘hydrargyrum.’ Mercury has been discovered in
Egyptian tombs dating as far back as 1500 BC. The chemical
symbol, Hg, is derived from the Greek word hydrargyros,
meaning ‘water silver.’ Mercury was known in antiquity and
used by alchemists. Its neurological effects were recognized
early, and its use in the hat-making trade gave rise to the phrase
‘mad as a hatter.’ Mercury has been used commercially and
medically for centuries. In the past it was a common constituent
of many medications, for example, it was used in the
treatment of syphilis. Use of mercury has been drastically
reduced in recent years. Within the twentieth century, mercury
used to be in every physician’s or pharmacist’s armamentarium,
for example, calomel was commonly used in infant
teething powders in the 1930s and 1940s. | [Waste Disposal]
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform to EPA regulations governing
storage, transportation, treatment, and waste disposal.
Accumulate for purification and re-use if possible. Mercury
vapors may be adsorbed or treated with sulfide solutions
and then sent to mercury recovery operations | [Purification Methods]
After air has been bubbled through mercury for several hours to oxidise metallic impurities, it is filtered to remove coarser particles of oxide and dirt, then sprayed through a 4-ft column containing 10% HNO3. It is washed with distilled water, dried with filter paper and distilled under vacuum. [Schenk in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p8 1963.] | [Flammability and Explosibility]
Mercury is not combustible. | [reaction suitability]
reagent type: catalyst
core: mercury | [Carcinogenicity]
There is no conclusive evidence from epidemiological
studies that mercury increases
cancer risk in humans.12 In the few studies in
which increases have been reported, concomitant
exposure to other known carcinogens has
confounded the results. The IARC has determined
that there is inadequate evidence in
humans for the carcinogenicity of mercury and
mercury compounds.12 In animals there is inadequate
evidence for carcinogenicity of metallic
mercury and limited evidence for the carcinogenicity
of mercuric chloride. | [Environmental Fate]
Mercury cycles through various environmental phases by exchange from ground to air and back again. Metallic and dimethylmercury, which are volatile, will be released as mercury vapor that can travel long distances before being redeposited. When found in surface waters and soils it will degas into the surrounding air where natural currents and winds spread the materials until they are deposited back on the surface waters and soils. The majority of mercury returned to the soil or water is by wet partition and accounts for almost all of the mercury found in lakes with no other input source. Inert mercury will deposit bound to particulates in aerosols. Once deposited, mercury must adsorb to soil or sediment particulates or be returned to the atmosphere. This cycle continues with a portion of the mercury revolatilizing into the atmosphere in each cycle. | [storage]
Precautions should be taken to prevent spills of mercury because
drops of the liquid metal can easily become lodged in floor cracks, behind cabinets, and
equipment, etc., with the result that the mercury vapor concentration in the laboratory may
then exceed the safe and allowable limits. Containers of mercury should be kept tightly sealed
and stored in secondary containers (such as a plastic pan or tray) in a well-ventilated area.
When breakage of instruments or apparatus containing significant quantities of Hg is possible,
the equipment should be placed in a plastic tray or pan that is large enough to contain the
mercury in the event of an accident. Transfers of mercury between containers should be
carried out in a fume hood over a tray or pan to confine any spills. | [Toxicity evaluation]
Mercury has a great affinity for sulfhydryl moieties and, hence,
binds and inactivates a variety of enzymes. Methylmercury also
initiates lipid peroxidation, which can produce alterations in
cell membranes. Mercury damages the microtubules in the
brain by reacting with the protein tubulin. | [Toxics Screening Level]
The ITSL for mercury from chronic inhalation exposure is 0.3 μg/m3 with an annual averaging time. |

| Questions And Answer | Back Directory | [Chemical Properties]
Mercury is the only metal that is a liquid metal at room temperature. Occurring naturally as mercuric sulfide (in cinnabar ore) because of its low boiling point can be isolated readily from the ore and condensing the resulting vapor to form a metal that is 99.9% pure. Solid mercury is ductile and very malleable and is soft enough to cut with a knife. A poor conductor of heat, mercury can conduct electricity but behaves much like a noble gas. It does not react with most acids but can react with very strong acids and dissolves readily to form amalgams with many metals, including gold, zinc, and aluminum.
| [History]
Although mercury is known from early times and was used by alchemists, its first modern scientific applications date back to 1643 when Torricelli used it in the barometer to measure pressure and about eight decades later Fahrenheit used it in the thermometer to measure temperature. Before this, mercury’s use was confined to decorative work, gold extraction and medicines. The element was named after the planet mercury and its symbol Hg is taken from the Latin word hydrargyrum, which means liquid silver.
The element does not occur in nature in native form. Its principal mineral is cinnabar, the red mercuric sulfide, HgS. Black mercuric sulfide, metacinnabar, also is found in nature. Other ores are livingstonite, HgSb4S7; coloradite, HgTe; tiemannite, HgSe; and calomel, HgCl. Its concentration in the earth’s crust is estimated to be 0.08 mg/kg. The average concentration in sea water is about 0.03 µg/L.
| [Uses]
Some of the most important uses of mercury are in the electrical and electrolytic applications. A broad range of such applications include mercury batteries and cells in portable radios, microphones, cameras, hearing aids, watches, smoke alarms, and wiring and switching devices. Other notable applications are in mercury vapor lamps, fluorescent tubes and electrical discharge tubes. Mercury electrodes are widely used in electrolytic cells. Mercury cathodes are employed in the electrolysis of sodium chloride to produce caustic soda and chlorine. Another major use, as mentioned earlier, is in thermometers, manometers, barometers and other pressure-sensing devices. Mercury also is used as a catalyst in making urethane foams and vinyl chloride monomers. Mercury and its compounds long have been used as fungicides in paints and in agriculture. Mercury compounds are used in medicines, pigments and analytical reagents.
In mercury arc lamps producing ultraviolet rays; in mercury boilers; manufacture of all mercury salts, mirrors; as catalyst in oxidation of organic Compounds; extracting gold and silver from ores; making amalgams, electric rectifiers, mercury fulminate; also in dentistry; in determining N by Kjeldahl method, for Millon's reagent; as cathode in electrolysis, electroanalysis, and many other uses. Also in pharmaceuticals, agricultural chemicals, anti-fouling paints.
| [Production Methods]
Mercury mostly is obtained from its sulfide ore, cinnabar. The process involves roasting cinnabar in a furnace between 600 to 700°C. Mercury vapors are cooled and condensed into metal:
HgS + O2 → Hg + SO2
Mercury may also be extracted from cinnabar by reduction of the ore with lime at elevated temperature:
4HgS + 4CaO → 4Hg + 3CaS + CaSO4
Smaller quantities of metal are recovered from mercury-containing industrial and municipal wastes, such as amalgams and batteries. The scrap material is heated in a retort and the vapors of mercury are condensed into highpurity metal.
| [Toxicity]
Elemental mercury and all its compounds are highly toxic by all routes of exposure. The element has significant vapor pressure at ambient temperatures (0.0018 torr at 25°C) that can produce severe inhalation hazard. The symptoms from short exposure to high concentration of mercury vapors are bronchitis, coughing, chest pain, respiratory distress, salivation and diarrhea (Patnaik, P. 1999. A Comprehensive Guide to the Hazardous Properties of Chemical Substances, 2nd ed., New York: John Wiley and Sons). Other symptoms are tremor, insomnia and depression. Mercury can cause damage to kidney, liver, lungs and brain. Organomercury compounds and inorganic salt solutions can be absorbed into the body through skin contact and cause severe poisoning. It accumulates as Hg2+ in the brain and kidneys. US EPA has classified mercury as one of the priority pollutant metals in environmental matrices.
