[24] Due to bioaccumulation it works its way up through the food web and thus biomagnifies, resulting in high concentrations among populations of some species. This piece of modern art, made from mercury sulfide, hangs on the wall at the DELA recycling company in Dorsten, Germany. Mercury irreversibly inhibits selenium-dependent enzymes (see below) and may also inactivate S-adenosyl-methionine, which is necessary for catecholamine catabolism by catechol-O-methyl transferase. Exposure to mercury can occur from breathing contaminated air, from eating foods that have acquired mercury residues during processing, f… [96] When broken indoors, bulbs may emit sufficient mercury vapor to present health concerns, and the U.S. Environmental Protection Agency recommends evacuating and airing out a room for at least 15 minutes after breaking a fluorescent light bulb. Because they are more soluble in water, mercuric salts are usually more acutely toxic than mercurous salts. So how much is too much? [85] A 2004 Institute of Medicine (IOM) committee favored rejecting any causal relationship between thiomersal-containing vaccines and autism. [56] Autopsy findings point to a half-life of inorganic mercury in human brains of 27.4 years. Mercury is a naturally occurring metal that is in many everyday products, albeit in tiny amounts. In 2008, Russian lawyer Karinna Moskalenko claimed to have been poisoned by mercury left in her car,[99] while in 2010 journalists Viktor Kalashnikov and Marina Kalashnikova accused Russia's FSB of trying to poison them. Workers wash masses of broken glass from the shredded lamps to recover luminescent material and mercury from the glass shards. "They just break open the lamps," recalls Flasbarth of a visit to India, "And the vaporized mercury ends up in their homes.". [80] The word is derived from the Greek, where άκρο means end or extremity, and οδυνη means pain. ATSDR. [24] α-Lipoic acid (ALA) has been shown to be protective against acute mercury poisoning in several mammalian species when it is given soon after exposure; correct dosage is required, as inappropriate dosages increase toxicity. [48] The EPA also developed the "Fish Kids" awareness campaign for children and young adults [49] on account of the greater impact of mercury exposure to that population. We use cookies to improve our service for you. If, however, you drink mercury, hardly any of it stays in the system - most of it exits the body once it has performed its function. An Account of the Effect of Mercurial Vapors on the Crew of His Majesty's Ship Triumph, in the year 1810. It was only in the modern period that it became clear that the metal is highly poisonous. [16], Some mercury compounds, especially organomercury compounds, can also be readily absorbed through direct skin contact. It is difficult or impossible to interpret urine samples of patients undergoing chelation therapy, as the therapy itself increases mercury levels in the samples. Due to the body's inability to degrade catecholamines (e.g. The U.S. Environmental Protection Agency (EPA) recommends consuming a daily maximum of 0.1 micrograms of mercury for each kilogram of your body weight. Also known as quicksilver, mercury (Hg) was once thought to heal broken bones and prolong life. It is cleared from the blood much more rapidly, with a half-life of seven to ten days, and it is metabolized much more quickly than methylmercury. [15], Small independent gold-mining operation workers are at higher risk of mercury poisoning because of crude processing methods. [37][38], Acute inhalation of high concentrations causes a wide variety of cognitive, personality, sensory, and motor disturbances. It was also used in electrical switches or relays that were built into machines until the mid-20th century, and it can be found in florescent lamps and even newer energy saving lamps. In the Middle Ages, it was used in alchemy and medicine. [3] Symptoms depend upon the type, dose, method, and duration of exposure. Producers of the bulbs use the purest possible materials. As methyl mercury accumulates in our lakes, streams, and oceans, it may enter our aquatic and terrestrial food chains. Organic Mercury:People may be exposed when they eat fish or shellfish contaminated with methy… In order to prevent mercury from escaping, a filtering ventilation system sucks the air away. [58], Mercuric chloride may cause cancer as it has caused increases in several types of tumors in rats and mice, while methyl mercury has caused kidney tumors in male rats. Mercury poisoning via heavily contaminated seafood and fish can harm a person's fertility as well as threaten their nervous system. Mercury is very dangerous if allowed to enter the body. The United States Environmental Protection Agency (EPA) issued recommendations in 2004 regarding exposure to mercury in fish and shellfish. Although its potential for toxicity in highly contaminated areas such as Minamata Bay, Japan, in the 1950's and 1960's, is well documented, research has shown that mercury can be a threat to the health of people and wildlife in many environments that are not obviously polluted. However, several studies found no clear clinical benefit from DMSA treatment for poisoning due to mercury vapor. When the first symptom appears, typically paresthesia (a tingling or numbness in the skin), it is followed rapidly by more severe effects, sometimes ending in coma and death. High mercury exposures deplete the amount of cellular selenium available for the biosynthesis of thioredoxin reductase and other selenoenzymes that prevent and reverse oxidative damage,[41] which, if the depletion is severe and long lasting, results in brain cell dysfunctions that can ultimately cause death. In acute toxicity, paresthesias, incoordination, dyspnea, metallic taste, lethargy, and confusion can be seen. Mercury is not absorbed through intact skin or from a healthy digestive tract in amounts that would cause toxic effects. The most dangerous form to human health and the environment is organic mercury, primarily in the form of methyl mercury. Place all broken objects on a paper towel. "No matter which mercury compound you introduce to the water, the mercury always comes back to us via things like seafood - and that in a concentrated form.". ", Kathryn J. Kitzmiller, Ph.D. [3][4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. Other symptoms may include kidney dysfunction (e.g. Following a certified case of mercury poisoning resulting from the use of an imported skin whitening product, the United States Food and Drug Administration warned against the use of such products. In 1996, the US Environmental Protection Agency set a new guideline for methyl mercury in the diet: 0.1 micrograms of mercury per kilogram of body weight per day (0.1 µg/kg/day). Mercury poisoning can be prevented or minimized by eliminating or reducing exposure to mercury and mercury compounds. ", pink disease – collected articles (63pp). These compounds have been implicated in causing brain and liver damage. Significant amounts of mercury are very bad for a growing baby in the womb, and may result in stunted neurological development, and problems with hearing or eyesight. [12], All of these, except elemental liquid mercury, produce toxicity or death with less than a gram. Mercury was once prescribed as a purgative. Although whole-blood mercury concentrations are typically less than 6 μg/L, diets rich in fish can result in blood mercury concentrations higher than 200 μg/L; it is not that useful to measure these levels for suspected cases of elemental or inorganic poisoning because of mercury's short half-life in the blood. Other important human-generated sources include gold production, nonferrous metal production, cement production, waste disposal, human crematoria, caustic soda production, pig iron and steel production, mercury production (mostly for batteries), and biomass burning. Tetsuya Endo, a professor at the Health Sciences University of Hokkaido, has tested whale meat purchased in the whaling town of Taiji and found mercury levels more than 20 times the acceptable Japanese standard. [26], The period between exposure to methylmercury and the appearance of symptoms in adult poisoning cases is long. Some analytical techniques are capable of distinguishing organic from inorganic forms of the metal. [53] Glutathione and N-acetylcysteine (NAC) are recommended by some physicians, but have been shown to increase mercury concentrations in the kidneys and the brain. [45] Mercury is allowed for fluorescent light bulbs because of pressure from countries such as Germany, the Netherlands and Hungary, which are connected to the main producers of fluorescent light bulbs: General Electric, Philips and Osram.[46]. Identifying and removing the source of the mercury is crucial. Chelation therapy for acute inorganic mercury poisoning can be done with DMSA, 2,3-dimercapto-1-propanesulfonic acid (DMPS), D-penicillamine (DPCN), or dimercaprol (BAL). An example of acute exposure would be mercury exposure due to an industrial accident. [31] Mercuric cyanide (Hg(CN)2) is a particularly toxic mercury compound that has been used in murders, as it contains not only mercury but also cyanide, leading to simultaneous cyanide poisoning. However, cosmetics containing mercury are often illegally imported. Secure the bag and label it as directed by your local health or fire department. "We've long known that mercury can accumulate in algae and fish," says Gebel. [17], Many traditional medicines, including Ayurvedic medicine and Traditional Chinese medicine contain mercury and other heavy metals. [35], In humans, approximately 80% of inhaled mercury vapor is absorbed via the respiratory tract, where it enters the circulatory system and is distributed throughout the body. To avoid the effects of mercury poisoning on their children, parents were known to purposefully maim or dismember their children to make them unable to work in the mines. Most of these pathways involve enzymes. The toxic damage appears to be determined by the peak value of mercury, not the length of the exposure.[27]. At high exposure levels methylmercury can be toxic to people. The shredded compact fluorescent tubes are stored in a silo until a spiral conveyor carefully carries them to a glass-washing area. The most dangerous mercury compound, dimethylmercury, is so toxic that even a few microliters spilled on the skin, or even on a latex glove, can cause death. At high exposure levels methylmercury can be toxic to people. Mercury thermometers and mercury light bulbs are not as common as they used to be, and the amount of mercury they contain is unlikely to be a health concern if handled carefully. On March 19, 2008, Tony Winnett, 55, inhaled mercury vapors while trying to extract gold from computer parts (by using liquid mercury to separate gold from the rest of the alloy), and died ten days later. Mercury sulfide can be disposed of through storage in old mines. When applied, the chemical readily absorbs through the skin into the bloodstream. Vapors may be present in such workplaces as dental offices, smelting operations, and locations where mercury has been spilled or released. You can find more information in our data protection declaration. Glass from lightbulbs is considered valuable in industrial processes, since it can withstand high temperatures and varying levels of pressure. May 2000, "Was Young's syndrome caused by exposure to mercury in childhood? EPA: Limiting mercury from US coal plants not 'necessary'. [34] Some mercury vapor is absorbed dermally, but uptake by this route is only about 1% of that by inhalation. [3] Most exposure is from eating fish, amalgam based dental fillings, or exposure at work. Mercury exposures in excess of dietary selenium intakes in young children can have severe neurological consequences, preventing nerve sheaths from forming properly. People tend to associate mercury with its silvery liquid form - perhaps found in old thermometers. [18][19], No scientific data support the claim that mercury compounds in vaccine preservatives cause autism[20] or its symptoms. [59], Infantile acrodynia (also known as "calomel disease", "erythredemic polyneuropathy", and "pink disease") is a type of mercury poisoning in children characterized by pain and pink discoloration of the hands and feet. [3] In fish, those higher up in the food chain generally have higher levels of mercury. During the Spanish conquest of the New World in the 16th and 17th centuries, slave mining of mercury deposits was common because the metal was used to purify the rich silver deposits in South America before being shipped back to Spain. Ethylmercury is a breakdown product of the antibacteriological agent ethylmercurithiosalicylate, which has been used as a topical antiseptic and a vaccine preservative (further discussed under Thiomersal below). What you need to know about mercury in fish and shellfish – Advice for women who might become pregnant women who are pregnant nursing mothers young children. In the body, elemental mercury can be converted to inorganic mercury. Fanconi syndrome) or neuropsychiatric symptoms such as emotional lability, memory impairment, or insomnia. [13], Human-generated sources, such as coal-burning power plants[14] emit about half of atmospheric mercury, with natural sources such as volcanoes responsible for the remainder. Top predatory fish, such as tuna or swordfish, are usually of greater concern than smaller species. Burnet, M.D. Elemental mercury:People may be exposed when they breathe air containing elemental mercury vapors. To that end, many governments and private groups have made efforts to heavily regulate the use of mercury, or to issue advisories about its use. The concentrations in both fluids tend to reach high levels early after exposure to inorganic forms, while lower but very persistent levels are observed following exposure to elemental or organic mercury. No explanation for this long latent period is known. Exposure to it can cause the neurological disorder erethism mercurialis - with at least one observable symptom, according to Thomas Gebel, a toxicologist at Germany's Federal Institute for Occupational Health and Safety in Dortmund. [24] Other exposure sources of organic mercury include phenylmercuric acetate and phenylmercuric nitrate. It is this type of mercury that can be harmful to your unborn baby and young child. By Wm. Mercury can damage many parts of your body, including your lungs, kidneys and nervous system (that includes the brain, spinal cord and nerves). [42], Diagnosis of elemental or inorganic mercury poisoning involves determining the history of exposure, physical findings, and an elevated body burden of mercury. Many mercury-containing compounds were once used in medicines. [98], Mercury has, allegedly, been used at various times to assassinate people. The glass washing process leaves behind a sludge with a high mercury content. But mercury vaporizes more slowly, it can take days or weeks, and could be inhaled over a longer period of time," says Gebel. Since the metal is quite dense, it weighs 1.7 times as much as the same volume of iron. Jochen Flasbarth, president of Germany's Federal Environment Agency, says children in some developing countries often expose themselves to the risks by disassembling florescent lamps and energy saving lamps to get at the metal inside. Cases of systemic toxicity from accidental swallowing are rare, and attempted suicide via intravenous injection does not appear to result in systemic toxicity,[27] though it still causes damage by physically blocking blood vessels both at the site of injection and the lungs. It's like cigarettes; deadly over long periods of exposure, but you aren't going to die if you walk into a smoky bar and have a drink. And when it vaporizes, it fills the air with tiny, invisible mercury atoms that are both scentless and soluble in oils or fats. "Its density cleans the intestine wonderfully.". Most oral and rectal thermometers contain about 0.5-0.6 grams of mercury. Mercury's zero oxidation state (Hg0) exists as vapor or as liquid metal, its mercurous state (Hg+) exists as inorganic salts, and its mercuric state (Hg2+) may form either inorganic salts or organomercury compounds. Some skin whitening products contain the toxic mercury(II) chloride as the active ingredient. CS1 maint: DOI inactive as of November 2020 (. This liquid form of mercury is especially dangerous because it vaporizes at room temperature. Even a simple thing such as a broken thermometer can lead to mercury poisoning. The amount of mercury deposited in a given area depends on how much mercury is released from local, regional, national, and international sources. There's also mercury in fluorescent lighting. [94] In Hong Kong in 2002, two products were discovered to contain between 9,000 and 60,000 times the recommended dose. However, broken items still require careful cleanup, as mercury can be hard to collect and it is easy to accidentally create a much larger exposure problem. If mercury spills, you will have a serious problem on your hands. Animal data indicate less than 0.01% of ingested mercury is absorbed through the intact gastrointestinal tract, though it may not be true for individuals suffering from ileus. If a person exposed to mercury stops breathing, use a bag and mask to give them air, but don't perform mouth-to-mouth resuscitation, since this contaminates the rescuer, too. Exposure to methylmercury causes increased levels of antibodies sent to myelin basic protein (MBP), which is involved in the myelination of neurons, and glial fibrillary acidic protein (GFAP), which is essential to many central nervous system (CNS). [97] Breakage of multiple bulbs presents a greater concern. [4][2] In those with acute poisoning from inorganic mercury salts, chelation with either dimercaptosuccinic acid (DMSA) or dimercaptopropane sulfonate (DMPS) appears to improve outcomes if given within a few hours of exposure. The trouble arises when it is broken down by bacteria into methylmercury—the dangerous, dietary form of mercury. The nerve poison can cause sleep disorders, agitation, and paralysis. One mechanism of mercury toxicity involves its irreversible inhibition of selenoenzymes, such as thioredoxin reductase (IC50 = 9 nM). Women who have been exposed to mercury in substantial excess of dietary selenium intakes during pregnancy are at risk of giving birth to children with serious birth defects. [50] If available, powdered sulfur may be applied to the spill, in order to create a solid compound that is more easily removed from surfaces than liquid mercury.[51]. Fold the paper towel and place in a zip locking bag. [7], The consumption of fish is by far the most significant source of ingestion-related mercury exposure in humans, although plants and livestock also contain mercury due to bioconcentration of mercury from seawater, freshwater, marine and lacustrine sediments, soils, and atmosphere, and due to biomagnification by ingesting other mercury-containing organisms. Michael J. Doherty MD: The Quicksilver Prize: Mercury vapor poisoning aboard HMS Triumph and HMS Phipps (2003). (A microgram is one millionth of a gram.) As a vapor, the mercury is inhaled as individual atoms and quickly absorbed by the lungs where its poisonous effects begin to develop. It’s expensive to clean up a mercury spill. Although it has been hypothesized that frequent low dosages of ALA may have potential as a mercury chelator, studies in rats have been contradictory. Why Is Mercury So Dangerous To Our Health? Methylmercury exposure during rodent gestation, a developmental period that approximately models human neural development during the first two trimesters of gestation,[28][29] has long-lasting behavioral consequences that appear in adulthood and, in some cases, may not appear until aging. Desquamation (skin peeling) can occur with severe mercury poisoning acquired by handling elemental mercury. Mercury is a metal. [25] A 2006 review of the risks and benefits of fish consumption found, for adults, the benefits of one to two servings of fish per week outweigh the risks, even (except for a few fish species) for women of childbearing age, and that avoidance of fish consumption could result in significant excess coronary heart disease deaths and suboptimal neural development in children. The mercury applied to lakes was found in young-of-the-year yellow perch within two months, whereas the mercury applied to wetlands and uplands had a slower but longer influx. [21], Compounds of mercury tend to be much more toxic than either the elemental form or the salts. © 2020 Deutsche Welle | The Not-So-Mad Hatter: Occupational Hazards of Mercury, "Bichloride of Mercury Killed Olive Thomas", "Mercury exposure and child development outcomes", "Colbert man dies from mercury poisoning", "Jeremy Piven Explains His Mystery Ailment", "Cases in vaccine court—legal battles over vaccines and autism", "Vaccines and Autism: A Tale of Shifting Hypotheses", "NYC Health Dept. For years, including the early part of his presidency, On September 5, 1920, silent movie actress. [2] Long-term complications may include kidney problems and decreased intelligence. Common brain-related symptoms mercury poisoning from fillings include fatigue, anxiety, depression, memory loss, and difficulty concentrating. Methylmercury is the type of mercury found in certain kinds of fish. But while mercury is generally considered highly poisonous, doctors in the late 19th century gave patients significant amounts of the element to treat intestinal obstructions. All of the children were found to have mercury levels below the EPA's public safety limit of 5.8 nanograms per milliliter (ng/mL). While no official government estimates of the labor force have been made, observers believe 20,000–50,000 work as galamseys in Ghana, a figure including many women, who work as porters. An early scientific study of mercury poisoning was in 1923–6 by the German inorganic chemist, Widespread mercury poisoning occurred in rural, In April 2000, Alan Chmurny attempted to kill a former employee, Marta Bradley, by pouring mercury into the. Mercury spills are dangerous — and they can be very difficult to clean up. [2] Methylmercury exposure in children may result in acrodynia (pink disease) in which the skin becomes pink and peels. Discussion on the topic includes debates on whether amalgam should be used, with critics arguing that its toxic effects make it unsafe. Privacy Policy | Sulfur is directed to the left part of this machine, while from above comes the liquid mercury. Mercury can be toxic in certain situations. Toxicological Profile for Mercury. His Oklahoma residence became so contaminated that it had to be gutted. [27][92][93] The use of skin whitening products is especially popular amongst Asian women. Mercury in bulbs is typically present as either elemental mercury liquid, vapor, or both, since the liquid evaporates at ambient temperature. Mercury exists in nature only as part of an ore (a type of rock made up of bonded materials), usually cinnabar, gold, or silver, and is liquid at temperatures as low as 30 degrees below zero. If you come in contact with high levels of mercury during pregnancy, it can cause real problems for you and your baby. [22][23], Methylmercury is the major source of organic mercury for all individuals. "It's not like with hot water - water vaporizes and is gone. [86] Autism incidence rates increased steadily even after thiomersal was removed from childhood vaccines. Warns Against Use of "Skin-lightening" Creams Containing Mercury or Similar Products Which Do Not List Ingredients", "Skin lightening in Asia? Mercury is distilled from this, just like in a liquor distillery. Patients with mercury toxicity can present with signs and/or symptoms suggestive of either acute or chronic exposure. This article explains how much to eat without affecting health and clarifies the risks of consuming too much. "There are historically documented cases that describe how people's handwriting changed. An estimated two-thirds of human-generated mercury comes from stationary combustion, mostly of coal. Dental amalgam is a possible cause of low-level mercury poisoning due to its use in dental fillings. This causes an autoimmmune response against MBP and GFAP and results in the degradation of neural myelin and general decline in function of the CNS. Mercury is a highly toxic element that is found both naturally and as an introduced contaminant in the environment. Emissions from Power Plants Since mercury occurs naturally in coal and other fossil fuels, when people burn these fuels for energy, the mercury becomes airborne and goes into the atmosphere. [5] In certain communities that survive on fishing, rates of mercury poisoning among children have been as high as 1.7 per 100.[4]. Thiomersal-Containing vaccines and autism.
