[12], All of these, except elemental liquid mercury, produce toxicity or death with less than a gram. one of the Medical Commissioners of the Navy, formerly Physician and Inspector of Hospitals to the Mediterranean Fleet. Acute toxicity might result in fever, fatigue, and clinical signs of pneumonitis. [4] Tests of the blood, urine, and hair for mercury are available but do not relate well to the amount in the body. 1973, Hursh et al. 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. It is a soft, spongy tissue that surrounds the…. The three forms are called elemental (or metallic) mercury, inorganic mercury compounds, and organic mercury compounds. Elemental mercury as a vapor has the ability to penetrate the CNS, where it is ionized and trapped, attributing to its significant toxic effects. It is commonly known as quicksilver and was formerly named hydrargyrum (/ h aɪ ˈ d r ɑːr dʒ ər ə m / hy-DRAR-jər-əm). Identifying and removing the source of the mercury is crucial. Hg 0 evaporates slowly to produce vapors, the primary health concern. Children and unborn babies are the most vulnerable to the effects of mercury poisoning. Mercury poisoning can be prevented or minimized by eliminating or reducing exposure to mercury and mercury compounds. Inorganic mercury is mercury combined with other chemical elements such as chlorine, sulfur or oxygen. [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. This will reduce the risk of fetal mercury exposure. [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. [3] In fish, those higher up in the food chain generally have higher levels of mercury. [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]. ELEMENTAL MERCURY TOXICITY. [5] In certain communities that survive on fishing, rates of mercury poisoning among children have been as high as 1.7 per 100.[4]. Mercury exposures in excess of dietary selenium intakes in young children can have severe neurological consequences, preventing nerve sheaths from forming properly. Be on the lookout for fish advisories in your area. Mercury salts affect primarily the gastrointestinal tract and the kidneys, and can cause severe kidney damage; however, as they cannot cross the blood–brain barrier easily, these salts inflict little neurological damage without continuous or heavy exposure. These include: Mercury poisoning is diagnosed with a physical exam and a blood and urine test. [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. Most people are exposed to mercury through diet and dental fillings. Form dictates toxicity. Semiconductor cells In the United States, exposure to o… Mercury is a type of toxic metal that comes in different forms within the environment. Our data do not allow any conclusion about the effectiveness of chelation therapy. Silver and gold production 20. It is based on Dr. Andrew Hall Cutler’s research. However, cosmetics containing mercury are often illegally imported. adrenaline), a person suffering from mercury poisoning may experience profuse sweating, tachycardia (persistently faster-than-normal heart beat), increased salivation, and hypertension (high blood pressure). [6], Forms of mercury exposure include metal, vapor, salt, and organic compound. Infants and young children who’ve been exposed to high levels of mercury may have delays in: High amounts of mercury can lead to long-term and sometimes permanent neurological changes. [3] Symptoms depend upon the type, dose, method, and duration of exposure. Top predatory fish, such as tuna or swordfish, are usually of greater concern than smaller species. Exposures to metallic mercury most often occur when metallic mercury is spilled, or when products that contain metallic mercury break, so that mercury is exposed to the air. Although it has been hypothesized that frequent low dosages of ALA may have potential as a mercury chelator, studies in rats have been contradictory. Metabolism of mercury compounds to other forms of mercury can occur within the tissues of the body. You can help prevent toxicity by limiting your exposure to this potentially dangerous metal. [87] Currently there is no accepted scientific evidence that exposure to thiomersal is a factor in causing autism.[88]. Experimental animal and epidemiological study findings have confirmed the interaction between selenium and methylmercury. [98], Mercury has, allegedly, been used at various times to assassinate people. The best way to treat mercury poisoning is to stop your exposure to the metal. It’s also possible to develop mercury poisoning from eating too much seafood. A 23‐year woman, 2 years after injecting herself with elemental mercury developed disabling generalized myoclonus and ataxia. [37][38], Acute inhalation of high concentrations causes a wide variety of cognitive, personality, sensory, and motor disturbances. [95], Fluorescent lamps contain mercury, which is released when bulbs break. Mercury poisoning is a type of metal poisoning due to exposure to mercury. Most countries have signed the Minamata Convention on Mercury. [39] Although it has many functions, thioredoxin reductase restores vitamins C and E, as well as a number of other important antioxidant molecules, back into their reduced forms, enabling them to counteract oxidative damage. 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. Three siblings with inhaled elemental mercury toxicity are described, and the signs and symptoms of mercury toxicity, interpretation of mercury concentrations, and management of elemental mercury exposure are reviewed. The United States Environmental Protection Agency (EPA) issued recommendations in 2004 regarding exposure to mercury in fish and shellfish. Neurological effects from mercury toxicity are often permanent. It is the inorganic and organic mercury that can cause toxicity. When applied, the chemical readily absorbs through the skin into the bloodstream. This case of acrodynia was traced to exposure of mercury from a carton of 8-foot fluorescent light bulbs that had broken in a potting shed adjacent to the main nursery. Affected children may show red cheeks, nose and lips, loss of hair, teeth, and nails, transient rashes, hypotonia (muscle weakness), and increased sensitivity to light. [24] Only DMSA is FDA-approved for use in children for treating mercury poisoning. [3] Less commonly, poisoning may occur as a method of attempted suicide. Long term, you may need continuing treatment to manage the effects of mercury poisoning, such as neurological effects. [24], Mercury occurs as salts such as mercuric chloride (HgCl2) and mercurous chloride (Hg2Cl2), the latter also known as calomel. Mercury is used in many industries, especially the electrical industry, and in many instruments such as thermometers and barometers. Bronzing 5. Though not studied quantitatively, the physical properties of liquid elemental mercury limit its absorption through intact skin and in light of its very low absorption rate from the gastrointestinal tract, skin absorption would not be high. 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. Circulatory failure is another possible type of complication. Some of the toxic effects of mercury are partially or wholly reversible provided specific therapy is able to restore selenium availability to normal before tissue damage from oxidation becomes too extensive. Toxicological Profile for Mercury. Ethnomedical practices 10. Barometers 3. It has been used clinically, but because of its toxicity this use is diminishing. Mercury in bulbs is typically present as either elemental mercury liquid, vapor, or both, since the liquid evaporates at ambient temperature. Mercury Detox: Separating Fact from Fiction. Chlor-alkali production 7. There is some controversy over whether it is a cause of autistic behaviors. Elemental mercury is a silvery, odorless liquid that evaporates slowly at room temperature, becoming a vapor. To that end, many governments and private groups have made efforts to heavily regulate the use of mercury, or to issue advisories about the use of mercury. [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. Compendium of Chemical Hazards: Inorganic Mercury/Elemental Mercury Page 2 of 17 Toxicological Overview Summary of Health Effects The main target organs of elemental and inorganic mercury toxicity are the central nervous system (CNS) and the kidneys. Due to the body's inability to degrade catecholamines (e.g. to elemental mercury vapour, and a tolerable intake of total mercury of 2 µg/kg body weight per day. SYMPTOMS OF ELEMENTAL MERCURY VAPOR EXPOSURE AND TOXICITY Prepared by the International Academy of Oral Medicine and Toxicology (IAOMT, www.iaomt.org); 2016 All dental amalgams, often called “silver fillings,” contain approximately 50% mercury… [32] The drug n-acetyl penicillamine has been used to treat mercury poisoning with limited success. Elemental mercury has a vapor pressure of 0.002 mm Hg at 25°C and will slowly evaporate at room temperatures. [2] Methylmercury exposure in children may result in acrodynia (pink disease) in which the skin becomes pink and peels. Fish is one of the most nutritious foods you can eat, but some types of fish contain high levels of mercury. Healthline's mission is to make people healthier through the power of information. The person may receive: Humidified oxygen or air; Breathing tube through the mouth into the lungs and use of a breathing machine (ventilator) Suctioning of mercury out of the lungs; Medicine to remove mercury and heavy metals from the body 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. Chelation therapy for acute inorganic mercury poisoning, a formerly common method, was done with DMSA, 2,3-dimercapto-1-propanesulfonic acid (DMPS), D-penicillamine (DPCN), or dimercaprol (BAL). These compounds were used in indoor latex paints for their antimildew properties, but were removed in 1990 because of cases of toxicity. 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. 1. Paper pulp production 18. Its characteristics have not been studied as extensively as those of methylmercury. Does it mean you need to avoid all fish? Thinking of doing a mercury detox? [97] Breakage of multiple bulbs presents a greater concern. [94] In Hong Kong in 2002, two products were discovered to contain between 9,000 and 60,000 times the recommended dose. The most common cause of mercury poisoning is from consuming too much methylmercury or organic mercury, which is linked to eating seafood. If you are concerned about your exposure to metallic mercury, you should consult your physician. Neon lamps 16. When detected early, mercury poisoning can be halted. Dr. Cutler was a professional chemical engineer with a Ph.D. in chemistry from Princeton who discovered that mercury was the cause of his own health issues. [52] No chelator for methylmercury or ethylmercury is approved by the FDA; DMSA is the most frequently used for severe methylmercury poisoning, as it is given orally, has fewer side-effects, and has been found to be superior to BAL, DPCN, and DMPS. 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. Toxicity from fish has two causes: Fish get mercury from the water they live in. Inhalational exposure is the most typical route of elemental mercury toxicity. Fluorescent and mercury lamps 12. If your mercury levels reach a certain point, your doctor will have you do chelation therapy. Batteries 4. Chelating agents are drugs that remove the metal from your organs and help your body dispose of them. Mov Disord. 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. If you eat a lot of mercury-containing seafood, stop immediately. Inhalation is the significant route of exposure to elemental mercury. At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. Elemental mercury poisoning probably causes cortical myoclonus. ELEMENTAL MERCURY. Metallic or elemental mercury (an odorless, shiny, silver-white liquid) is commonly used in thermometers, barometers and fluorescent light bulbs. His Oklahoma residence became so contaminated that it had to be gutted. When injected, the element has a very slow clearance, mainly renal. It is presumed not to have methylmercury's ability to cross the blood–brain barrier via a transporter, but instead relies on simple diffusion to enter the brain. If heated, it is a colorless, odorless gas. Decontamination requires removal of clothes, washing skin with soap and water, and flushing the eyes with saline solution as needed. 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. [36] Chronic exposure by inhalation, even at low concentrations in the range 0.7–42 μg/m3, has been shown in case–control studies to cause effects such as tremors, impaired cognitive skills, and sleep disturbance in workers. Mercury poisoning is the result of being exposed to too much mercury, either through the diet or environment. Such is the danger for the galamsey in Ghana and similar workers known as orpailleurs in neighboring francophone countries. The risk of toxicity depends on the type of mercury you have been exposed to. A bright future? Mercury in its various forms is particularly harmful to fetuses as an environmental toxin in pregnancy, as well as to infants. Mercury is most notable for its neurological effects. [17], Many traditional medicines, including Ayurvedic medicine and Traditional Chinese medicine contain mercury and other heavy metals. 1978). Trial rounds of chelation. [22][23], Methylmercury is the major source of organic mercury for all individuals. Electroplating 9. Fortunately mercury poisoning is very rare. Many popular foods are made with raw fish, including sushi. [43], Diagnosis of organic mercury poisoning differs in that whole-blood or hair analysis is more reliable than urinary mercury levels.[43]. [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. [33], Quicksilver (liquid metallic mercury) is poorly absorbed by ingestion and skin contact. Burnet, M.D. 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. 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. However, a sudden onset of any of these symptoms could be a sign of acute toxicity. Many popular sushi rolls are made with mercury-containing fish. The export from the European Union of mercury and some mercury compounds has been prohibited since 15 March 2010. This is a clinical approach and it is the definitive method to determine if you have mercury toxicity.. Inhalation of elemental mercury and ingestion of inorganic can cause acute or subacute toxicity; Organic mercury more likely causes chronic toxicity; Elemental Mercury Acute Exposure. The longest recorded latent period is five months after a single exposure, in the Dartmouth case (see History); other latent periods in the range of weeks to months have also been reported. If the exposure is chronic, urine levels can be obtained; 24-hour collections are more reliable than spot collections. account for central nervous system toxicity. [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. Mercury is an element that exists in several forms: elemental or metallic mercury, inorganic mercury compounds, and organic mercury compounds. Infrared detectors 13. Elemental and methylmercury are toxic to the central and peripheral nervous systems. [5] Chelation for those with long-term exposure is of unclear benefit. Mercury is a type of toxic metal that comes in different forms within the environment. [34] Some mercury vapor is absorbed dermally, but uptake by this route is only about 1% of that by inhalation. 1980), and some evidence suggests hepatic-mediated oxidation (Magos et al. Desquamation (skin peeling) can occur with severe mercury poisoning acquired by handling elemental mercury. It exists in three forms that have different properties, usage, and toxicity. [84], Since 2000, the thiomersal in child vaccines has been alleged to contribute to autism, and thousands of parents in the United States have pursued legal compensation from a federal fund. Mercury toxicity causes postural tremors, commonly referred to as “mercurial tremors,” and cerebellar dysfunction. 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. Eat larger types of fish on an occasional basis. Fingerprinting products 11. Mercury Mercury is an element and a metal that is found in air, water, and soil. [100], The examples and perspective in this article, Methylmercury and related organomercury compounds. [27][92][93] The use of skin whitening products is especially popular amongst Asian women. [40] Since the rate of oxygen consumption is particularly high in brain tissues, production of reactive oxygen species (ROS) is accentuated in these vital cells, making them particularly vulnerable to oxidative damage and especially dependent upon the antioxidant protection provided by selenoenzymes. Elemental mercury is liquid at room temperature. Atlanta, GA:Agency for Toxic Substances and Disease Registry. Children poisoned by mercury may develop nervous system, digestive system, and kidney damage. Take a blood or urine mercury test before conceiving. Many mercury-containing compounds were once used in medicines. [42], Diagnosis of elemental or inorganic mercury poisoning involves determining the history of exposure, physical findings, and an elevated body burden of mercury. If you suspect sudden mercury poisoning, call the Poison Control Center at 800-222-1222. Mercury poisoning by intravenous injection is a clinical emergency, potentially leading to death. Your doctor will ask about your symptoms and when they started. 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. 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. Warns Against Use of "Skin-lightening" Creams Containing Mercury or Similar Products Which Do Not List Ingredients", "Skin lightening in Asia? The most toxic is inhaling gaseous mercury. Bigeye tuna, marlin, and king mackerel also contain high levels of mercury. [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. [2] Long-term complications may include kidney problems and decreased intelligence. All rights reserved. [21], Compounds of mercury tend to be much more toxic than either the elemental form or the salts. This is especially useful if you fish for your own seafood. Dental amalgam is a possible cause of low-level mercury poisoning due to its use in dental fillings. [1] High-level exposure to methylmercury is known as Minamata disease. A 1987 report described a 23-month-old toddler who suffered anorexia, weight loss, irritability, profuse sweating, and peeling and redness of fingers and toes. Some skin whitening products contain the toxic mercury(II) chloride as the active ingredient. The diagnostic approach for patients with suspected mercury toxicity begins with a thorough history that includes occupations, hobbies, and levels of seafood intake.All toxic presentations, whether acute, chronic, or subacute, are difficult diagnoses because multiple organ systems are affected (eg, CNS, kidney, mucous membranes) and can mimic a variety of other diseases. Fanconi syndrome) or neuropsychiatric symptoms such as emotional lability, memory impairment, or insomnia. Elemental mercury is not well absorbed by the GI tract and, therefore, when ingested (eg, thermometers), is only mildly toxic. If you’re pregnant, the March of Dimes recommends eating no more than 6 ounces of tuna per week and 8 to 12 ounces of other types of fish. [3] Most exposure is from eating fish, amalgam based dental fillings, or exposure at work. Mercury in Tuna: Is This Fish Safe to Eat? These compounds have been implicated in causing brain and liver damage. 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). Its vapor is the most hazardous form. 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. [84] The CDC and the AAP followed the precautionary principle, which assumes that there is no harm in exercising caution even if it later turns out to be unwarranted, but their 1999 action sparked confusion and controversy that Thiomersal was the cause of autism. Mercury is a chemical element with the symbol Hg and atomic number 80. 22(13):1964-8. . Manage household spills of mercury (such as from, Avoid activities with known mercury exposure risk, such as home gold extraction. [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. By Wm. Sharks and swordfish are among the most common of these. Other causes of mercury poisoning can be environmental or from exposure to other forms of the metal. [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. Because they are more soluble in water, mercuric salts are usually more acutely toxic than mercurous salts. [80] The word is derived from the Greek, where άκρο means end or extremity, and οδυνη means pain.
