, 140 countries agreed in the Minamata Convention on Mercury by the United Nations Environment Programme (UNEP) to prevent emissions. , Mercury is extracted by heating cinnabar in a current of air and condensing the vapor. By far the largest use of mercury in the late 20th century was in the mercury cell process (also called the Castner-Kellner process) where metallic sodium is formed as an amalgam at a cathode made from mercury; this sodium is then reacted with water to produce sodium hydroxide. Volcanic eruptions can increase the atmospheric source by 4–6 times. There is also the red planet, called Mars, where ast… Jupiter and Saturn are the gas giants of the Solar System. Cleaning porous surfaces and clothing is not effective at removing all traces of mercury and it is therefore advised to discard these kinds of items should they be exposed to a mercury spill. The average was 0.069 μg/m3. Scientists refer to the atmospheres of Saturn and Jupiter as being more “polluted” because they have larger percentages of heavy metals such as methane and ammonia. However, when you consider the temperature, the spin, the density, and the size of Mercury, it is more likely that the iron in the planet has become a giant permanent magnet (ferromagnetic) with no active dynamo. Case–control studies have shown effects such as tremors, impaired cognitive skills, and sleep disturbance in workers with chronic exposure to mercury vapor even at low concentrations in the range 0.7–42 μg/m3.  Mercury deposits were discovered in the New World, and more than 100,000 tons of mercury were mined from the region of Huancavelica, Peru, over the course of three centuries following the discovery of deposits there in 1563. It is a standard in electrochemistry. From the mid-18th to the mid-19th centuries, a process called ", Gold and silver mining. Mercury(II) salts are a rare example of simple metal complexes that react directly with aromatic rings. Long-term, low-level exposure has been associated with more subtle symptoms of erethism, including fatigue, irritability, loss of memory, vivid dreams and depression. Occupational exposure has resulted in broad-ranging functional disturbance, including erethism, irritability, excitability, excessive shyness, and insomnia. , The tobacco plant readily absorbs and accumulates heavy metals such as mercury from the surrounding soil into its leaves. For this reason, Uranus and Neptune are … In the early 21st century, their use is declining and has been banned in some countries, states and medical institutions. These are subsequently inhaled during tobacco smoking. , The mines in Almadén (Spain), Monte Amiata (Italy), and Idrija (now Slovenia) dominated mercury production from the opening of the mine in Almadén 2500 years ago, until new deposits were found at the end of the 19th century. Most thermometers now use pigmented alcohol instead of mercury, and galinstan alloy thermometers are also an option. In one small study including 11 construction workers exposed to elemental mercury, patients were treated with DMSA and NAP. , Research on the treatment of mercury poisoning is limited. Environmental releases and disposal of mercury are regulated in the U.S. primarily by the United States Environmental Protection Agency. When this happened, the solar winds blew its atmosphere into space. It is small and rocky. Despite claims otherwise, Hg(III) and Hg(IV) compounds remain unknown.. The deep violet glow of a mercury vapor discharge in a germicidal lamp, whose spectrum is rich in invisible ultraviolet radiation. The ban applies to new devices only, and contains exemptions for the health care sector and a two-year grace period for manufacturers of barometers. Several laws give the EPA this authority, including the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, and the Safe Drinking Water Act. For every two orbits of the Sun, Mercury completes three rotations about its axis and up until 1965 it was thought that the same side of Mercury constantly faced the Sun. Many historic applications made use of the peculiar physical properties of mercury, especially as a dense liquid and a liquid metal: Others applications made use of the chemical properties of mercury: Mercury(I) chloride (also known as calomel or mercurous chloride) has been used in traditional medicine as a diuretic, topical disinfectant, and laxative.  It is also used in specialist medical care lamps for skin tanning and disinfection. The outer shell is only about 300 or 400 miles thick.  Astronomy . So it makes sense to think that a gas planet must be like a big, airy cloud floating out in space. 1.1% from mercury production, mainly for batteries. HgCl2 forms coordination complexes that are typically tetrahedral, e.g. , Mercury, as thiomersal, is widely used in the manufacture of mascara. Usually the salt is dissolved in water to produce a brine. It comes from hydrargyrum, a Latinized form of the Greek word ὑδράργυρος (hydrargyros), which is a compound word meaning "water-silver" (from ὑδρ- hydr-, the root of ὕδωρ, "water," and ἄργυρος argyros "silver") – since it is liquid like water and shiny like silver. , In the European Union, the directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (see RoHS) bans mercury from certain electrical and electronic products, and limits the amount of mercury in other products to less than 1000 ppm.  The convention was signed on 10 October 2013. Some believe this is because the core might still have some liquid properties with a functioning dynamo. Review of its safety has found that cinnabar can lead to significant mercury intoxication when heated, consumed in overdose, or taken long term, and can have adverse effects at therapeutic doses, though effects from therapeutic doses are typically reversible. If anyone knows how to get this thesis into the hands of someone at NASA or JPL, that is studying Mercury or has a scientific interest in the planets, please contact me. "Chlorine Online Diagram of mercury cell process", "Liquid-mirror telescope set to give stargazing a new spin", "Laval University Liquid mirrors and adaptive optics group", "Population-Based Inorganic Mercury Biomonitoring and the Identification of Skin Care Products as a Source of Exposure in New York City", "IMERC Fact Sheet: Mercury Use in Batteries", "Did the Mad Hatter have mercury poisoning? The impact scaring on the surface gives testament to Mercury's gas free past. It is commonly known as quicksilver and was formerly named hydrargyrum (/ haɪˈdrɑːrdʒərəm / hy-DRAR-jər-əm).  In the early 20th century, mercury was administered to children yearly as a laxative and dewormer, and it was used in teething powders for infants. , Liquid mercury is a part of popular secondary reference electrode (called the calomel electrode) in electrochemistry as an alternative to the standard hydrogen electrode. Former mercury mines may be suited for constructive re-use. The "hot Jupiters" found in orbits of a few days are much hotter than the surface of Mercury. Mercury was used to extract silver from the lucrative mines in New Spain and Peru. Mercuric compounds such as mercury(II) chloride or potassium tetraiodomercurate(II) can be added to protein crystals in an effort to create heavy atom derivatives that can be used to solve the phase problem in X-ray crystallography via isomorphous replacement or anomalous scattering methods. Mercury is a chemical element with the symbol Hg and atomic number 80. With continuing exposure, a fine tremor develops and may escalate to violent muscular spasms. It is associated with the planet Mercury; the astrological symbol for the planet is also one of the alchemical symbols for the metal; the Sanskrit word for alchemy is Rasaśāstra. Heating of mercury, or of compounds of mercury that may decompose when heated, should be carried out with adequate ventilation in order to minimize exposure to mercury vapor.  The "first" emperor of China, Qín Shǐ Huáng Dì—allegedly buried in a tomb that contained rivers of flowing mercury on a model of the land he ruled, representative of the rivers of China—was killed by drinking a mercury and powdered jade mixture formulated by Qin alchemists (causing liver failure, mercury poisoning, and brain death) who intended to give him eternal life. ), Basic Mercury Subsulphate; Turpeth Mineral, Quantities of liquid mercury ranging from 90 to 600 grams (3.2 to 21.2 oz) have been recovered from elite, As an electrically conductive liquid, it was used in, Owing to its acoustic properties, mercury was used as the propagation medium in, Mercury was used for preserving wood, developing. One example is Hg2+3(AsF−6)2.. Mercury has another problem.It is near Sun and the solar wind is also blowing out the atmosphere. Choose Mercury as your Gas Supplier and get Natural Gas for your home or business and enjoy great Energy deals when you are a Gas and Electricity customer , Recent atmospheric mercury contamination in outdoor urban air was measured at 0.01–0.02 µg/m3.  Nevertheless, thiomersal has been removed from, or reduced to trace amounts in all U.S. vaccines recommended for children 6 years of age and under, with the exception of inactivated influenza vaccine.. Graphic showing o ur best understanding of giant planet interiors in 2003.  Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69 g/cm3 when liquid to 14.184 g/cm3 when solid. Since the amalgam destroys the aluminium oxide layer which protects metallic aluminium from oxidizing in-depth (as in iron rusting), even small amounts of mercury can seriously corrode aluminium. Thus, industries that release high concentrations of mercury into the environment agreed to install maximum achievable control technologies (MACT). Mercury’s heavy atmospheric pressure condensed the planet’s core and created its crumpled surface with ridges that extend hundreds of miles. Mercury is the smallest planet in our solar system. Most contain comparatively non-toxic inorganic mercury, but products containing highly toxic organic mercury have been encountered.. If scientists would like to study the core of a gas giant roughly the size of Neptune or Uranus, they need look no further than Mercury. They form tetrahedral complexes with other ligands but the halides adopt linear coordination geometry, somewhat like Ag+ does. Scientists have theorized that the crumpled surface and lobe-shaped scarps (cliffs and ridges) were formed when the planet cooled and shrank.  Worker health in functioning mines is at high risk. This study found mercury concentrations significantly elevated over outdoor concentrations, at a range of 0.0065 – 0.523 μg/m3. The terrestrial planets are Mercury, Venus, Earth, and Mars. Mercury is the closest planet to the sun. Preindustrial deposition rates of mercury from the atmosphere may be about 4 ng /(1 L of ice deposit). The rule was deemed not sufficient to protect the health of persons living near coal-fired power plants, given the negative effects documented in the EPA Study Report to Congress of 1998. This page was last edited on 31 December 2020, at 05:58. Once fully cooled, the dense metallic core was left in a weak but permanent magnet state. By-products of any such chloralkali process are hydrogen (H2) and sodium hydroxide (NaOH), which is commonly called caustic soda or lye. Products containing mercury include: auto parts, batteries, fluorescent bulbs, medical products, thermometers, and thermostats. Records are incomplete and unclear, but government commissions have estimated that some two million pounds of mercury are unaccounted for. When Mercury’s dynamo began to weaken, the solar winds began to blow its atmosphere into space. It reverts to the elements upon heating near 400 °C, as was demonstrated by Joseph Priestley in an early synthesis of pure oxygen.  Gaseous mercury is added to cold cathode argon-filled lamps to increase the ionization and electrical conductivity. Jupiter's composition is mainly hydrogen and helium. At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. Time on Mercury. , In the United States, the Environmental Protection Agency is charged with regulating and managing mercury contamination.  In 2002, several lakes in Norway were found to have a poor state of mercury pollution, with an excess of 1 µg/g of mercury in their sediment.  Chelation therapy with both drugs resulted in the mobilization of a small fraction of the total estimated body mercury. Mercury is the closest planet to the Sun and due to its proximity it is not easily seen except during twilight. Mercury dissolves many metals such as gold and silver to form amalgams. HgCl2−4. Currently available drugs for acute mercurial poisoning include chelators N-acetyl-D, L-penicillamine (NAP), British Anti-Lewisite (BAL), 2,3-dimercapto-1-propanesulfonic acid (DMPS), and dimercaptosuccinic acid (DMSA). Skin tanner containing a low-pressure mercury vapor lamp and two infrared lamps, which act both as light source and electrical ballast. In 2008, Norway's Minister of Environment Development Erik Solheim said: "Mercury is among the most dangerous environmental toxins. Mercury and its compounds have been used in medicine, although they are much less common today than they once were, now that the toxic effects of mercury and its compounds are more widely understood.  Mercury(II) selenide (HgSe) and mercury(II) telluride (HgTe) are also known, these as well as various derivatives, e.g. If long-period gas giant planets are found in the TRAPPIST-1 system, then it could help resolve a longstanding debate about the formation of our own Solar System's gas giant planets. Other elements that do not readily form amalgams with mercury include platinum. The Deep Space Atomic Clock (DSAC) under development by the Jet Propulsion Laboratory utilises mercury in a linear ion-trap-based clock. An argon-filled lamp without mercury will have dull spots and will fail to light correctly. The European Union directive calling for compact fluorescent bulbs to be made mandatory by 2012 has encouraged China to re-open cinnabar mines to obtain the mercury required for CFL bulb manufacture. Iron is an exception, and iron flasks have traditionally been used to trade mercury. Mercury doesn't really have an atmosphere. Our universe is an inconceivably vast space that contains billions of heavenly bodies, and even then, most of outer space is completely empty! Solid mercury is malleable and ductile and can be cut with a knife.. level 2  Cement kilns that burn hazardous waste are held to a looser standard than are standard hazardous waste incinerators in the United States, and as a result are a disproportionate source of mercury pollution. , In November 2014 "large quantities" of mercury were discovered in a chamber 60 feet below the 1800-year-old pyramid known as the "Temple of the Feathered Serpent," "the third largest pyramid of Teotihuacan," Mexico along with "jade statues, jaguar remains, a box filled with carved shells and rubber balls. Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications.  However newer data published in 2015 showed that after introduction of the stricter controls mercury declined sharply, indicating that the Clean Air Act had its intended impact. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. Another mercury compound, merbromin (Mercurochrome), is a topical antiseptic used for minor cuts and scrapes that is still in use in some countries. This use allows a new uncontaminated electrode to be available for each measurement or each new experiment. Mercury thermometers are still occasionally used in the medical field because they are more accurate than alcohol thermometers, though both are commonly being replaced by electronic thermometers and less commonly by galinstan thermometers. Detailed Synopsis: Mercury began in the same swirling gas cloud as the rest of the planets, moons and other objects in our solar system. Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. ", Products containing mercury were banned in Sweden in 2009.. 199Hg and 201Hg are the most often studied NMR-active nuclei, having spins of 1⁄2 and 3⁄2 respectively. , A study in geometric mean urine mercury concentration identified a previously unrecognized source of exposure (skin care products) to inorganic mercury among New York City residents. I got to thinking, and wondered whether Mercury might be such an object. The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide. Methylmercury, a generic term for compounds with the formula CH3HgX, is a dangerous family of compounds that are often found in polluted water. For example, Williston Lake in northern British Columbia, created by the damming of the Peace River in 1968, is still sufficiently contaminated with mercury that it is inadvisable to consume fish from the lake.  The strong affinity of mercury for carbon rich sediments has also been observed in salt marsh sediments of the River Mersey mean of 2 mg/kg up to 5 mg/kg. To be considered a gas giant, the planet has to be made up of mostly gas, be located in the outer area of the solar system, and have a mass that is ten times that of Earth. Jupiter. Historically, one of the largest releases was from the Colex plant, a lithium isotope separation plant at Oak Ridge, Tennessee. Although this form of mercury appears to be less toxic than other forms, its use in traditional Chinese medicine has not yet been justified, as the therapeutic basis for the use of cinnabar is not clear.. The farther away they are, the more time it takes to make one trip around the Sun. We think of a gas as something very . Indicative of its tendency to bond to itself, mercury forms mercury polycations, which consist of linear chains of mercury centers, capped with a positive charge. The novel use of mercury allows very compact atomic clocks, with low energy requirements, and is therefore ideal for space probes and Mars missions.  A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Species of fish that are high on the food chain, such as shark, swordfish, king mackerel, bluefin tuna, albacore tuna, and tilefish contain higher concentrations of mercury than others. Mercury and most of its compounds are extremely toxic and must be handled with care; in cases of spills involving mercury (such as from certain thermometers or fluorescent light bulbs), specific cleaning procedures are used to avoid exposure and contain the spill. And in the 2007 film Sunshine, the Icarus II spacecraft goes into orbit around Mercury … Nevada's McDermitt Mine, the last mercury mine in the United States, closed in 1992. Thermometers and sphygmomanometers containing mercury were invented in the early 18th and late 19th centuries, respectively. It reacts with chlorine to give mercuric chloride, which resists further oxidation. A year on Mercury lasts 88 Earth days. There is also Venus, the brightest planet in the solar system, as well as Earth, the blue planet the only planet which sustains life, and our precious home. 15918 I was reminded today of the idea of a chthonian planet. Some medical thermometers, especially those for high temperatures, are filled with mercury; they are gradually disappearing. Mercury(II) chloride (also known as mercuric chloride or corrosive sublimate) was once used to treat syphilis (along with other mercury compounds), although it is so toxic that sometimes the symptoms of its toxicity were confused with those of the syphilis it was believed to treat. Best known is mercury(II) chloride, an easily sublimating white solid.  North America contributed approximately 11% of the total global anthropogenic mercury emissions in 1995. induces disproportionation to Hg2+ and elemental mercury. Mercury-containing compounds are also of use in the field of structural biology. The most toxic forms of mercury are its organic compounds, such as dimethylmercury and methylmercury. Those low-pressure lamps emit very spectrally narrow lines, which are traditionally used in optical spectroscopy for calibration of spectral position. Fish and shellfish have a natural tendency to concentrate mercury in their bodies, often in the form of methylmercury, a highly toxic organic compound of mercury. Edlich, Richard F.; Rhoads, Samantha K.; Cantrell, Holly S.; Azavedo, Sabrina M. and Newkirk, Anthony T. CS1 maint: BOT: original-url status unknown (, standard conditions for temperature and pressure, membrane cell or diaphragm cell technologies, United States Environmental Protection Agency, Mercury-Containing and Rechargeable Battery Management Act, "Atomic weights of the elements 2013 (IUPAC Technical Report)", "Magnetic Susceptibility of the Elements And Inorganic Compounds", Random House Webster's Unabridged Dictionary, "Why is mercury liquid? We see the cloud tops (beneath a transparent, mostly hydrogen upper atmosphere). Preeminent is mercury(II) sulfide, HgS, which occurs in nature as the ore cinnabar and is the brilliant pigment vermillion. Mercury(II) is the most common oxidation state and is the main one in nature as well. Far beneath Jupiter's atmosphere is a gigantic ocean of liquid metallic hydrogen, which would look and behave like mercury except that hydrogen has 60 percent the density of water. The planet has long puzzled scientists because the core and crust appear to have been pressured into its current compact condition. However, a large heavy atmosphere with strong wind currents and weather patterns under great pressure will account for these features. Water run-off from such sites is a recognized source of ecological damage. ", "Two States Pass First-time Bans on Mercury Blood Pressure Devices", "Title 21—Food and Drugs Chapter I—Food and Drug Administration Department of Health and Human Services Subchapter D—Drugs for Human Use Code of federal regulations". Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). Mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury), by inhalation of mercury vapor, or by ingesting any form of mercury. , Alchemists thought of mercury as the First Matter from which all metals were formed. Or, why do relativistic effects not get into chemistry textbooks?  Gaseous mercury is also found in some electron tubes, including ignitrons, thyratrons, and mercury arc rectifiers. Mercury reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury (spill kits also use activated carbon and powdered zinc).. Today, the use of mercury in medicine has greatly declined in all respects, especially in developed countries. Electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet light, which then causes the phosphor in the tube to fluoresce, making visible light. ", "Mercury: Spills, Disposal and Site Cleanup", "Glacial Ice Cores Reveal A Record of Natural and Anthropogenic Atmospheric Mercury Deposition for the Last 270 Years", "What is EPA doing about mercury air emissions? Emerging out the bottom, the pressure is now intense, and it's starting to get quite warm, and there's nothing but the dark abyss of ever-denser hydrogen gas beneath you. Organic mercury compounds are historically important but are of little industrial value in the western world. Mercury fulminate is a detonator widely used in explosives.. They believed that different metals could be produced by varying the quality and quantity of sulfur contained within the mercury. The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance).  Mercury(I) chloride, a colorless solid also known as calomel, is really the compound with the formula Hg2Cl2, with the connectivity Cl-Hg-Hg-Cl. In 2002, the U.S. Senate passed legislation to phase out the sale of non-prescription mercury thermometers. It started with the same basic chemical composition as the other planets with the same general proportion of iron to rock to gaseous materials. The gas-giant planets Jupiter, Saturn, Uranus and Neptune in our solar system are quite different in mass, density, and in chemical composition than the inner terrestrial planets Mercury, Venus, Earth, and Mars. In Lamanai, once a major city of the Maya civilization, a pool of mercury was found under a marker in a Mesoamerican ballcourt.  It is also used as a disinfectant. Mercury can cause both chronic and acute poisoning. When added to neon filled tubes the light produced will be inconsistent red/blue spots until the initial burning-in process is completed; eventually it will light a consistent dull off-blue color.. , The EPA announced new rules for coal-fired power plants on 22 December 2011. I had a quick look at modelling this and noticed there would seem to be critical point that if the planet crossed it then the process would start to accelerate exponentially. Toxic effects include damage to the brain, kidneys and lungs. The stability of the 6s shell is due to the presence of a filled 4f shell. Thus species that are high on the food chain amass body burdens of mercury that can be ten times higher than the species they consume. Satisfactory alternatives to Hg in products are Mercury(II) fulminate is a primary explosive which is mainly used as a primer of a cartridge in firearms. It is estimated that over 3,000 people suffered various deformities, severe mercury poisoning symptoms or death from what became known as Minamata disease. The purest of these was gold, and mercury was called for in attempts at the transmutation of base (or impure) metals into gold, which was the goal of many alchemists. Although that can be considered a natural level of exposure, regional or global sources have significant effects. A gas giant is a giant planet composed mainly of hydrogen and helium. . Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Your services 22 MERCURY Mercury is the closest planet to the Sun and the smallest one in the Solar System—it’s only a bit larger than our Moon. 11% from gold production. Thiomersal (called Thimerosal in the United States) is an organic compound used as a preservative in vaccines, though this use is in decline. , Hg is the modern chemical symbol for mercury. , A serious industrial disaster was the dumping of mercury compounds into Minamata Bay, Japan. , Norway enacted a total ban on the use of mercury in the manufacturing and import/export of mercury products, effective 1 January 2008. When it formed, its core was a liquid iron dynamo. The gas and ice giant planets take longer to orbit the Sun because of their great distances. The element was named after the Roman god Mercury, known for his speed and mobility.  Many of the industrial mercury releases of the 20th century came from this process, although modern plants claimed to be safe in this regard. The human-generated half can be divided into the following estimated percentages:, The above percentages are estimates of the global human-caused mercury emissions in 2000, excluding biomass burning, an important source in some regions. The FDA has "inadequate data to establish general recognition of the safety and effectiveness" of the mercury ingredients in these products. Television and film writers, too, have found the planet an ideal location for storytelling. The absence of a filled inner f shell is the reason for the somewhat higher melting temperature of cadmium and zinc, although both these metals still melt easily and, in addition, have unusually low boiling points. , Former mines in Italy, the United States and Mexico, which once produced a large proportion of the world supply, have now been completely mined out or, in the case of Slovenia (Idrija) and Spain (Almadén), shut down due to the fall of the price of mercury.  Mercury is still used in some diuretics although substitutes now exist for most therapeutic uses. In contrast to planetary bodies covered with a hard surface crust (the Earth, for example), there is no jovian surface.
