Just how dangerous is mercury, anyway?
People tend to associate mercury with its silvery liquid form — as found in old thermometers. But it was also used in electrical switches or relays that were built into machines until the mid-20th century. Later, it was florescent lamps and some early energy saving lamps.The liquid form of mercury is especially dangerous because it vaporizes at room temperature. And when it vaporizes, it fills the air with tiny, invisible mercury atoms that are both scentless and soluble in oils or fats.Lege plus -
Why We Need and Fear Mercury, the Liquid Metal
Mercury, which usually appears as a thick silvery fluid, is the only metal that’s liquid at room temperature. Its elemental symbol is Hg, which comes from the Greek word “hydrargyrum,” meaning “liquid silver.” In fact, it’s also called quicksilver.We use mercury in a wide range of products, from thermometers and barometers to batteries and pesticides. But mercury is extremely poisonous, and we can absorb it by touch, inhalation, or consumption. It builds up in the body with each exposure and is very difficult to remove. If you get too much in you, you can suffer from mercury poisoning, which is both unpleasant and potentially fatal.That’s why you have to be careful not to break a mercury thermometer or a compact fluorescent lightbulb. It’s also why people are concerned about mercury in industrial waste and pesticides flowing into rivers and oceans and being absorbed by fish … which are then eaten by people.Lege plus -
mercury
Although extremely toxic, this odourless, colourless substance has a wide variety of applications. In agriculture it is used as a fungicide, in medicine it was sometimes employed as a topical antiseptic in concentrations of one part per 2,000 parts of water, and in the chemical industry it serves as a catalyst in the manufacture of vinyl chloride and as a starting material in the production of other mercury compounds. Mercury(II) oxide, HgO, provides elemental mercury for the preparation of various organic mercury compounds and certain inorganic mercury salts. This red or yellow crystalline solid is also used as an electrode (mixed with graphite) in zinc-mercuric oxide electric cells and in mercury batteries. Mercury(II) sulfide, HgS, is a black or red crystalline solid used chiefly as a pigment in paints, rubber, and plastics.Lege plus -
mercury processing
Mercury (Hg) has a unique combination of physical properties. Its low melting point (−38.87 °C [−38 °F]) and boiling point (356.9 °C [674 °F]), high specific gravity (13.5 grams per cubic centimetre), uniform volume expansion over the entire range of temperatures in its liquid state, and high surface tension (so that it does not wet glass) make it useful for the measurement of temperature in thermometers and of pressure in barometers and manometers. In addition, the high electrical conductivity of liquid mercury has led to its use in sealed electric switches and relays, industrial power rectifiers, fluorescent and mercury-vapour lamps, mercury cell batteries, and as moving cathodes in the large-scale production of chlorine and caustic soda.Because mercury is highly toxic, care must be exercised in its handling and transport. By limiting exposure to mercury metal, vapours, and compounds through such preventive measures as proper ventilation, plant cleanliness and personal hygiene, industrial plants can be made relatively safe from the dangers of mercury poisoning.Lege plus -
Mercury: a liquid metal
Mercury is a heavy, silvery and very toxic metal. One of the most well-known features of mercury is that in normal conditions this metal is liquid and only freezes at –38.8°C! In nature there are only two elements that are liquid in normal conditions – mercury and bromine.In the earth’s crust, mercury is a very rare element, but rocks in which mercury is found usually contain it in rather high concentrations. This is because mercury mixes poorly with elements that make up most of the earth’s crust, and so “accumulations” of minerals containing mercury are formed. The most abundant of them are cinnabar (mercury sulfide HgS) and corderoit (Hg₃S₂Cl₂).Lege plus -
What is mercury?
Mercury occurs naturally in the environment and exists in a large number of forms. Like lead or cadmium, mercury is a constituent element of the earth, a heavy metal. In pure form, it is known alternatively as "elemental" or "metallic" mercury (also expressed as Hg(0) or Hg0). Mercury is rarely found in nature as the pure, liquid metal, but rather within compounds and inorganic salts. Mercury can be bound to other compounds as monovalent or divalent mercury (also expressed as Hg(I) and Hg(II) or Hg2+, respectively). Many inorganic and organic compounds of mercury can be formed from Hg(II)Lege plus -
What is Mercury?
Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature. It is used in older thermometers, fluorescent light bulbs and some electrical switches. When dropped, elemental mercury breaks into smaller droplets which can go through small cracks or become strongly attached to certain materials. At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. If heated, it is a colorless, odorless gas. Elemental mercury is an element that has not reacted with another substance. When mercury reacts with another substance, it forms a compound, such as inorganic mercury salts or methylmercury.Lege plus -
A Guide to Mercury Applications in Metalurgy
Terence Bell is a former writer who has been involved in the rare earth and minor metal industries for over 10 years.Mercury, or 'quicksilver' as it is otherwise known, is a dense, toxic metal element that exists in liquid form at room temperature. Produced and studied for millennia, mercury's use has steadily declined since the 1980s as a result of greater attention to the negative health impacts that it has on humans and the environment.Lege plus
