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.[65]. [50] Mercury compounds are found in some over-the-counter drugs, including topical antiseptics, stimulant laxatives, diaper-rash ointment, eye drops, and nasal sprays. States were given until November 2006 to impose stricter controls, but after a legal challenge from several states, the regulations were struck down by a federal appeals court on 8 February 2008. You fall through this abyss for a very, very long time. The general belief is that these gas giants formed first as icy and rocky planets similar to the terrestrial planets Mercury, Venus, Earth and Mars. Since fish are less efficient at depurating than accumulating methylmercury, methylmercury concentrations in the fish tissue increase over time. [100][101], Mercury also enters into the environment through the improper disposal (e.g., land filling, incineration) of certain products. [46] Thiomersal is metabolized to ethyl mercury. "Chapter 3: Manufacturing Processes Involving Mercury. The core is approximately 2,200 to 2,400 miles in diameter. It is estimated that over 3,000 people suffered various deformities, severe mercury poisoning symptoms or death from what became known as Minamata disease. Based on the size of the metallic core, it should be possible to approximate the original size of Mercury by using the solar system’s average mass/gas to iron ratio. Mercury is the closest planet to the Sun and due to its proximity it is not easily seen except during twilight. . Although that can be considered a natural level of exposure, regional or global sources have significant effects. The coefficient of volume expansion is 181.59 × 10−6 at 0 °C, 181.71 × 10−6 at 20 °C and 182.50 × 10−6 at 100 °C (per °C). The impact scaring on the surface gives testament to Mercury's gas free past. ", "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". It is a standard in electrochemistry. 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. [5], It has a freezing point of −38.83 °C and a boiling point of 356.73 °C,[6][7][8] both the lowest of any stable metal, although preliminary experiments on copernicium and flerovium have indicated that they have even lower boiling points (copernicium being the element below mercury in the periodic table, following the trend of decreasing boiling points down group 12). 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.[49]. If heated, it is a colorless, odorless gas. The plant operated in the 1950s and 1960s. Skin tanner containing a low-pressure mercury vapor lamp and two infrared lamps, which act both as light source and electrical ballast. They believed that different metals could be produced by varying the quality and quantity of sulfur contained within the mercury. well, airy. Mercury was used to extract silver from the lucrative mines in New Spain and Peru. The following methods try to transform the planets into something useful for settlers that will move to their satellites. We see the cloud tops (beneath a transparent, mostly hydrogen upper atmosphere). A day on Mercury lasts 59 Earth days. 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. [59] Last, but not least, the triple point of mercury, −38.8344 °C, is a fixed point used as a temperature standard for the International Temperature Scale (ITS-90).[5]. 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. [104], A serious industrial disaster was the dumping of mercury compounds into Minamata Bay, Japan. Additionally, the Mercury-Containing and Rechargeable Battery Management Act, passed in 1996, phases out the use of mercury in batteries, and provides for the efficient and cost-effective disposal of many types of used batteries. Mercury(II) fulminate is a primary explosive which is mainly used as a primer of a cartridge in firearms. The average was 0.069 μg/m3. [134] There are restrictions for mercury concentration in packaging (the limit is 100 ppm for sum of mercury, lead, hexavalent chromium and cadmium) and batteries (the limit is 5 ppm). There is also the red planet, called Mars, where ast… [63] It is also used in specialist medical care lamps for skin tanning and disinfection. In March 2005, the EPA promulgated a regulation[129] that added power plants to the list of sources that should be controlled and instituted a national cap and trade system. 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. 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. 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).[11]. [130] 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 and ice giant planets take longer to orbit the Sun because of their great distances. Mercury poisoning can result in several diseases, including acrodynia (pink disease), Hunter-Russell syndrome, and Minamata disease. Satisfactory alternatives to Hg in products are [64] Gaseous mercury is added to cold cathode argon-filled lamps to increase the ionization and electrical conductivity. 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 is made up of distinct layers, similar to Earth. At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. Being a soft metal, mercury forms very stable derivatives with the heavier chalcogens. Mercury(II) is the most common oxidation state and is the main one in nature as well. [128], The United States Clean Air Act, passed in 1990, put mercury on a list of toxic pollutants that need to be controlled to the greatest possible extent. 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). 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. The planet has long puzzled scientists because the core and crust appear to have been pressured into its current compact condition. [12][13] Sodium amalgam is a common reducing agent in organic synthesis, and is also used in high-pressure sodium lamps. Methylmercury, a generic term for compounds with the formula CH3HgX, is a dangerous family of compounds that are often found in polluted water. [22][23] By 500 BC mercury was used to make amalgams (Medieval Latin amalgama, "alloy of mercury") with other metals. Scientists have theorized that the crumpled surface and lobe-shaped scarps (cliffs and ridges) were formed when the planet cooled and shrank. 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. [107] While mercury is a constituent of tobacco smoke,[108] studies have largely failed to discover a significant correlation between smoking and Hg uptake by humans compared to sources such as occupational exposure, fish consumption, and amalgam tooth fillings. This study found mercury concentrations significantly elevated over outdoor concentrations, at a range of 0.0065 – 0.523 μg/m3. Toxic effects include damage to the brain, kidneys and lungs. Science Anatomy & Physiology Astronomy ... Why doesn't the gas on a gas giant escape into space, as it has on Mercury? [56][57][58], Liquid mercury is a part of popular secondary reference electrode (called the calomel electrode) in electrochemistry as an alternative to the standard hydrogen electrode. 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. Like silver, mercury reacts with atmospheric hydrogen sulfide. "[21], The ancient Greeks used cinnabar (mercury sulfide) in ointments; the ancient Egyptians and the Romans used it in cosmetics. 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. [6][7], Mercury does not react with most acids, such as dilute sulfuric acid, although oxidizing acids such as concentrated sulfuric acid and nitric acid or aqua regia dissolve it to give sulfate, nitrate, and chloride. Lighting containing mercury can be bombarded/oven pumped only once. For this reason, Uranus and Neptune are … Unlike organocadmium and organozinc compounds, organomercury compounds do not react with water. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity. [99], Artificial lakes may be contaminated with mercury due to the absorption by the water of mercury from submerged trees and soil. Mercury is the closest planet to the sun. Stable derivatives include the chloride and nitrate. The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure. Some medical thermometers, especially those for high temperatures, are filled with mercury; they are gradually disappearing. [15], Mercury was found in Egyptian tombs that date from 1500 BC. From bottom to top: Jupiter, Saturn, Uranus and Neptune. It is small and rocky. Edlich, Richard F.; Rhoads, Samantha K.; Cantrell, Holly S.; Azavedo, Sabrina M. and Newkirk, Anthony T.

A) water cycle began B) night and day occur C) seasons develop D) planets were formed 18. 15918 I was reminded today of the idea of a chthonian planet. Most contain comparatively non-toxic inorganic mercury, but products containing highly toxic organic mercury have been encountered.[116][117]. Historically, one of the largest releases was from the Colex plant, a lithium isotope separation plant at Oak Ridge, Tennessee. Blue mass, a pill or syrup in which mercury is the main ingredient, was prescribed throughout the 19th century for numerous conditions including constipation, depression, child-bearing and toothaches. [120] Acute exposure to mercury vapor has been shown to result in profound central nervous system effects, including psychotic reactions characterized by delirium, hallucinations, and suicidal tendency. Hydrogeochemical release of mercury from gold-mine tailings has been accounted as a significant source of atmospheric mercury in eastern Canada. The miniaturized Deep Space Atomic Clock is a linear ion-trap-based mercury ion clock, designed for precise and real-time radio navigation in deep space. Preeminent is mercury(II) sulfide, HgS, which occurs in nature as the ore cinnabar and is the brilliant pigment vermillion.

Most thermometers now use pigmented alcohol instead of mercury, and galinstan alloy thermometers are also an option. [94], Natural sources, such as volcanoes, are responsible for approximately half of atmospheric mercury emissions. Usually the salt is dissolved in water to produce a brine. A 2001 study measured mercury levels in 12 indoor sites chosen to represent a cross-section of building types, locations and ages in the New York area. The densities of the gas giants are much less than the densities of the rocky, terrestrial worlds of the solar system. The longest-lived radioisotopes are 194Hg with a half-life of 444 years, and 203Hg with a half-life of 46.612 days. 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. It started with the same basic chemical composition as the other planets with the same general proportion of iron to rock to gaseous materials. [135] In July 2007, the European Union also banned mercury in non-electrical measuring devices, such as thermometers and barometers. They usually have the formula HgR2, which are often volatile, or HgRX, which are often solids, where R is aryl or alkyl and X is usually halide or acetate. Credit: NASA Coined by the science fiction writer, James Blish, this is another term used to describe the 4 outermost planets in the Solar System: Jupiter, Saturn, Uranus and Neptune. [11] Hydroxides of mercury are poorly characterized, as they are for its neighbors gold and silver. So it makes sense to think that a gas planet must be like a big, airy cloud floating out in space. induces disproportionation to Hg2+ and elemental mercury. 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. Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. The term "gas giant" was originally synonymous with "giant planet", but in the 1990s it became known that Uranus and Neptuneare really a distinct class of giant planet, being composed mainly of heavier volatile substances (which are referred to as "ices"). An argon-filled lamp without mercury will have dull spots and will fail to light correctly. Jupiter's composition is mainly hydrogen and helium. [35], Abandoned mercury mine processing sites often contain very hazardous waste piles of roasted cinnabar calcines. Thousands of prisoners were used by the Luo Xi mining company to establish new tunnels. In the United States, non-prescription sale of mercury fever thermometers has been banned since 2003. The most toxic forms of mercury are its organic compounds, such as dimethylmercury and methylmercury.
