A highly toxic form (methylmercury) builds up in fish, shellfish and animals that eat fish. Fish and shellfish are the main sources of methylmercury exposure to that typically have higher levels of mercury include king mackerel, marlin, orange roughy, shark, swordfish, tilefish, and ahi and bigeye tuna. Many of these types of fish are used in sources of mercury can be fillings that contain up to 50% mercury by weight and can release mercury vapor, fluorescent light bulbs that use electricity to excite mercury vapor, and mercury fever thermometers made of y exists in several forms: elemental or metallic mercury, inorganic mercury compounds, and organic mercury y exposure at high levels can harm the brain, heart, kidneys, lungs, and immune system. High levels of methylmercury in the bloodstream of unborn babies and young children may harm the developing nervous system, making the child less able to think and and symptoms of methylmercury poisoning may include:Impairment of peripheral bances in sensations ("pins and needles" feelings). Of speech,Elemental (metallic) mercury primarily causes health effects when it is breathed as a vapor where it can be absorbed through the and symptoms of acute elemental (metallic) mercury poisoning include:Disturbances in s in nerve mance deficits on tests of cognitive exposures may result in kidney effects, respiratory failure and t your doctor if you believe you have been exposed to mercury. Treatment for mercury toxicity includes removal of the source of mercury exposure, supportive care, and chelation therapy to help remove the metals from the ing of mercury-containing products is one of the best ways to help prevent mercury releases to the environment by keeping these products out of landfills and y is a naturally occurring element. Mercury is also contained in some of the products we use, which may be found in your home, at the dentist, and at schools. This article provides links to information about sources of mercury exposure, potential health effects, fish that may contain mercury, consumer products that contain mercury, and ways to reduce your exposure to guideconcussions & brain injuries: symptoms, tests, to better manage your are the forms sources of mercury? Coal-burning power plants are the largest human-caused source of mercury emissions to the air in the united states, accounting for over 40 percent of all domestic human-caused mercury emissions. Burning hazardous wastes, producing chlorine, breaking mercury products, and spilling mercury, as well as the improper treatment and disposal of products or wastes containing mercury, can also release it into the environment. Mercury in the air eventually settles into water or onto land where it can be washed into water. Once deposited, certain microorganisms can change it into methylmercury, a highly toxic form that builds up in fish, shellfish and animals that eat fish. Methylmercury builds up more in some types of fish and shellfish than that typically have higher levels of mercury of these types of fish are used in sushi. White albacore canned tuna typically has three times as much mercury as chunk light canned tuna. The levels of methylmercury in fish and shellfish depend on what they eat, how long they live and how high they are in the food works with the u. Fish is a beneficial part of the diet, so epa & fda encourage people to continue to eat fish that are low in r less common exposure to mercury that can be a concern is breathing mercury vapor. These exposures can occur when elemental mercury or products that contain elemental mercury break and release mercury to the air, particularly in warm or poorly-ventilated indoor effects of mercury. Mercury exposure at high levels can harm the brain, heart, kidneys, lungs, and immune system of people of all ages. However, it has been demonstrated that high levels of the bloodstream of unborn babies and young children may harm the s system, making the child less able to think and ical effects of mercury. Birds and mammals that eat fish are more exposed to mercury than other animals in water ecosystems. At high levels of exposure, methylmercury's harmful effects on these animals include death, reduced reproduction, slower growth and development, and abnormal ng mercury releases. Epa issues regulations that require industry to reduce mercury releases to air and water and to properly treat and dispose of mercury wastes. Epa also works with industry to promote voluntary reductions in mercury use and releases, and with partners in state, local and tribal governments to improve their mercury reduction programs. The public can contribute to mercury reduction efforts by purchasing mercury-free products and correctly disposing of products that contain mercury by reducing demand for products whose production leads to the release of mercury into the factors determine the severity of health effects from mercury exposure? Are mainly exposed to methylmercury, an organic compound, when they eat fish and shellfish that contain methylmercury. Whether an exposure to the various forms of mercury will harm a person's health depends on a number of factors. Almost all people have at least trace amounts of methylmercury in their tissues, reflecting methylmercury'read presence in the environment and people's exposure through ption of fish and shellfish. The factors that determine how health effects are from mercury exposure include chemical form of mercury;. Methylmercury exposure in the womb, which can result from a mother's consumption of fish and shellfish that contain methylmercury, can adversely affect a baby's growing brain and nervous system. Impacts on cognitive thinking, memory, attention, language, and fine motor and visual spatial skills have been seen in children exposed to methylmercury in the womb. Recent human biological monitoring by the centers for disease control and prevention in 1999 and 2000 (pdf) shows that most people have blood mercury levels below a level associated with possible health effects. More recent data from the cdc support this general aks of methylmercury poisonings have made it clear that adults, children, and developing fetuses are at risk from ingestion exposure to methylmercury. During these poisoning outbreaks some mothers with no symptoms of nervous system damage gave birth to infants with severe disabilities, it became clear that the developing nervous system of the fetus may be more vulnerable to methylmercury than is the adult nervous more information on fish consumption advisories across the country, visit epa's fish consumption web are the signs and symptoms of methylmercury poisoning? Of speech, hearing, walking; concerned about their exposure to methylmercury should consult their are the side effects of elemental mercury? Metallic) mercury primarily causes health effects when it is breathed as a vapor where it can be absorbed through the lungs.

These exposures can occur when elemental mercury is spilled or products that contain elemental mercury break and expose mercury to the air, particularly in warm or poorly-ventilated indoor are the signs and symptoms of elemental mercury? Deficits on tests of cognitive higher exposures there may be kidney effects, respiratory failure and death. People concerned about their exposure to elemental mercury should consult their are the side effects of other mercury compounds (inorganic and organic)? Exposures to inorganic mercury may result in damage to the gastrointestinal tract, the nervous system, and the kidneys. Both inorganic and organic mercury compounds are absorbed through the gastrointestinal tract and affect other systems via this route. However, organic mercury compounds are more readily absorbed via ingestion than inorganic mercury are the signs and symptoms of high exposures to inorganic mercury? Disturbances; concerned about their exposure to inorganic mercury should consult their guideconcussions & brain injuries: symptoms, tests, about mercury in batteries? Button cell batteries are miniature batteries in the shape of a coin or button that are used to provide power for a large variety of small portable electronic use and disposal of mercury-added button cells are unregulated at the federal do not have to be labeled;. Because button batteries currently are not widely targeted for recycling, almost all of this mercury presumably ends up in the municipal solid waste stream where it is either incinerated or a more information on batteries, see epa's web page on consumer and commercial products. Silver fillings used by dentists to restore teeth are composed of a metal "amalgam" containing roughly 50% elemental mercury and 50% other metals (mostly silver with some tin and copper). Of dental amalgam mercury found in amalgam fillings has raised some safety concerns over the years. Amalgam can release small amounts of mercury vapor over time, and patients can absorb these vapors by inhaling or ingesting ing to the centers for disease control and prevention (cdc), there is little scientific evidence that the health of the vast majority of people with dental amalgam is compromised, nor that removing amalgam fillings has a beneficial effect on health. Public health service found "insufficient evidence of a link between dental mercury and health problems, except in rare instances of allergic reaction. Food and drug administration (fda) consumer update on dental amalgam advises, as a precaution, that pregnant women and persons who may have a health condition that makes them more sensitive to mercury exposure should discuss dental treatment options with their health care practitioner. If dental patients do not want to use mercury amalgam, there are several non-mercury restorative materials available. The american dental association provides a brochure for dental patients on the advantages and disadvantages of various types of dental nmental releases of mercury from dental amalgam y from dental amalgam is a major source of controllable mercury released to the environment and likely will remain a significant concern into the y from dental amalgam is released to the environment through three primary pathways:Through cremation of bodies containing dental majority of dental mercury amalgam is discharged from dental offices to wastewater treatment systems. For more information on environmental releases of mercury from dental amalgam, see epa's mercury web page on consumer and commercial about mercury in fish? A well-balanced diet that includes a variety of fish and shellfish can contribute to heart health and children's proper growth and r, nearly all fish and shellfish contain traces of methylmercury. For most people, the risk from exposure to methylmercury by eating fish and shellfish is not a health concern. Yet some fish and shellfish contain higher levels of mercury that may harm an unborn baby or young child's developing nervous system. The risks from methlymercury in fish and shellfish depend on the amount of fish and shellfish eaten and the levels of methylmercury in the fish. Fluorescent light bulb (also referred to as a "lamp") is a gas-discharge bulb that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that causes a phosphor to fluoresce, producing visible light. Mercury is an essential component of all fluorescent light bulbs, and allows these bulbs to be energy-efficient light of fluorescent : the standard straight "linear" tube comes in a variety of diameters and lengths. Switching from traditional incandescent bulbs to cfls is an effective, simple change everyone can make right now to help use less electricity at home and prevent greenhouse gas emissions that lead to global climate about cfls – general information on energy star-qualified compact fluorescent light bulbs (cfls), where to use cfls in a home, and how to choose the right type of cfl contain a very small amount of mercury sealed within the glass tubing. No mercury is released when the bulbs are intact (not broken) or in use, but cfls can break and release mercury vapor if dropped or roughly handled. These recommendations will help to minimize any exposure to released mercury encourages the recycling of burned out fluorescent bulbs rather than disposing of them in regular household trash. Recycling of burned out cfls is one of the best ways to help prevent the release of mercury to the environment by keeping mercury out of landfills and incinerators. Since 2001, with the exception of nza vaccines (flu), thimerosal is not used as a preservative in routinely recommended childhood learn more about this use of thimerosal, please see information from the food and drug administration (fda) on medicines that contain mercury and thimerosal in vaccines, and information from the centers for disease control and prevention on thimerosal in vaccines. There are two general types of mercury thermometers that measure body temperature: (1) oral/rectal/baby thermometers, containing about 0. However glass thermometers may break while in use, releasing harmful mercury vapor and exposing people in the immediate indoor area. Mercury thermometers are also likely to break after being discarded in regular trash, resulting in mercury releases in the landfill or trash incinerator, or during transportation to either location. It is for this reason the american academy of pediatrics (aap) encourages parents to remove mercury thermometers from their homes to prevent accidental exposure and ctions on sales of mercury fever order to help remove the threat of mercury fever thermometer breakage and subsequent release of mercury vapor indoors, some states and municipalities have passed laws or ordinances prohibiting the manufacture, sale and/or distribution of these thermometers. As of october 2, 2008, thirteen states have laws that limit the manufacture, sale and/or distribution of mercury fever thermometers:The health care without harm web site presents information on specific state laws and municipal atives: mercury-free fever thermometers. Alternatives most comparable in cost and use to the mercury fever thermometer include battery and solar powered digital thermometers. The battery is a button cell battery and may contain a small amount of mercury, so it should be recycled through a local battery collection program or household hazardous waste collection center.

Consult your local or state collection program regarding where batteries should be to do if a mercury fever thermometer breaks. If mercury spills out of a broken thermometer and is not cleaned up, it will evaporate into invisible vapor, potentially reaching dangerous levels in indoor air. If a thermometer breaks in your home, please follow epa's recommended cleanup steps to carefully clean up and dispose of the broken glass and silver mercury beads. These recommendations will help minimize any exposure to released mercury al of old mercury fever encourages the recycling of mercury fever thermometers rather than disposing of them in regular household trash. Recycling is one of the best ways to help prevent the release of mercury to the environment by keeping mercury out of landfills and trash states and local agencies have developed collection/exchange programs for mercury-containing devices such as thermometers. For information about these programs, contact your local officials to find out when and where a collection will be held in your ing and encourages the recycling of mercury-containing products rather than disposing of them in regular household trash. Recycling of mercury-containing products is one of the best ways to help prevent mercury releases to the environment by keeping these products out of landfills and localities have collection/exchange programs for mercury-containing devices, such as thermometers, manometers, and thermostats, and recycling programs for fluorescent light bulbs. If you accidentally break a mercury-containing product during use, or improperly dispose of such products, they will release mercury vapors that are harmful to human and ecological - information on what to do, and what never to do, if you spill mercury. Mercury-containing tal mercury has properties that have led to its use in many different products and industrial sectors. While some manufacturers have reduced or eliminated their use of mercury in products, there are still many consumer items in the marketplace that contain mercury. Epa encourages individuals, organizations and businesses to use non-mercury alternatives and to recycle unused mercury-containing products whenever er and commercial products - this web page provides more extensive information on mercury-containing products, plus links to related information from other federal agencies, state environmental agencies, and non-governmental 's database on mercury-containing products and alternatives - this searchable database contains publicly available information on consumer and commercial products that contain mercury, and also information on non-mercury alternatives. The primary source of information on mercury-containing products is the imerc mercury-added products database, which is discussed below. Information on non-mercury alternatives is gathered from a variety of public sources, including industry associations, non-governmental organizations, numerous web sites and published reports. The information is updated tate mercury education & reduction clearinghouse (imerc) mercury-added products database - the imerc database is managed by the northeast waste management officials' association (newmoa). It presents information on: (1) the amount and purpose of mercury in specific products that are sold in eight imerc-member states; (2) the total amount of mercury in these products sold nationally in a given year; and (3) the manufacturers of these products.

See additional wikipedia, the free to: navigation, y toxicity, mercury overdose, mercury intoxication, hydrargyria, weakness, poor coordination, numbness in the hands and feet[1]. 2] methylmercury exposure in children may result in acrodynia (pink's disease) in which the skin becomes pink and peels. 3] in fish, those higher up in the food chain generally have higher levels of mercury. 3] human activities that release mercury into the environment include the burning of coal and mining of gold. 4] tests of the blood, urine, and hair for mercury are available but do not relate well to the amount in the body. Includes eating a diet low in mercury, removing mercury from medical and other devices, proper disposal of mercury, and not mining further 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. 5] in certain communities that survive on fishing, rates of mercury poisoning among children have been as high as 1.

Symptoms of mercury poisoning include peripheral neuropathy, presenting as paresthesia or itching, burning, pain, or even a sensation that resembles small insects crawling on or under the skin (formication); skin discoloration (pink cheeks, fingertips and toes); swelling; and desquamation (shedding or peeling of skin). Epinephrine), a person suffering from mercury poisoning may experience profuse sweating, tachycardia (persistently faster-than-normal heart beat), increased salivation, and hypertension (high blood pressure). 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. 8] exposure to mercury can occur from breathing contaminated air,[9] from eating foods that have acquired mercury residues during processing,[10] from exposure to mercury vapor in mercury amalgam dental restorations,[11] and from improper use or disposal of mercury and mercury-containing objects, for example, after spills of elemental mercury or improper disposal of fluorescent lamps. Of these, except elemental liquid mercury produce toxicity or death with less than a gram. 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. Of whale and dolphin meat, as is the practice in japan, is a source of high levels of mercury poisoning. 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. 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. 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. Independent gold-mining operation workers are at higher risk of mercury poisoning because of crude processing methods. And many of its chemical compounds, especially organomercury compounds, can also be readily absorbed through direct contact with bare, or in some cases (such as methylmercury) insufficiently protected, skin. Mercury and its compounds are commonly used in chemical laboratories, hospitals, dental clinics, and facilities involved in the production of items such as fluorescent light bulbs, batteries, and explosives. Traditional medicines, including ayurvedic medicine and traditional chinese medicine contain mercury and other heavy metals. Scientific data support the claim that mercury compounds in vaccine preservatives cause autism[20] or its symptoms. Of mercury tend to be much more toxic than either the elemental form or the salts. 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. Period between exposure to methylmercury and the appearance of symptoms in adult poisoning cases is long. 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. The toxic damage appears to be determined by the peak value of mercury, not the length of the exposure. Prefrontal cortex or dopamine neurotransmission could be especially sensitive to even subtle gestational methylmercury exposure[30] and suggests that public health assessments of methylmercury based on intellectual performance may underestimate the impact of methylmercury in public ercury 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). It is cleared from the blood much more rapidly, with a half-life of seven to 10 days, and it is metabolized much more quickly than methylmercury. 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. 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. 31][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. Of ingested mercury is absorbed through the intact gastrointestinal tract, though it may not be true for individuals suffering from ileus. 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. 34] some mercury vapor is absorbed dermally, but uptake by this route is only about 1% of that by inhalation. 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. 42 μg/m3, has been shown in case control studies to cause effects such as tremors, impaired cognitive skills, and sleep disturbance in workers. Elemental mechanism of mercury toxicity involves its irreversible inhibition of selenoenzymes, such as thioredoxin reductase (ic50 = 9 nm). 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 y in its various forms is particularly harmful to fetuses as an environmental toxin in pregnancy, as well as to infants. 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. Mercury exposures in excess of dietary selenium intakes in young children can have severe neurological consequences, preventing nerve sheaths from forming properly. Of elemental or inorganic mercury poisoning involves determining the history of exposure, physical findings, and an elevated body burden of mercury. 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.

It is difficult or impossible to interpret urine samples of patients undergoing chelation therapy, as the therapy itself increases mercury levels in the samples. Of organic mercury poisoning differs in that whole-blood or hair analysis is more reliable than urinary mercury levels. Poisoning can be prevented (or minimized) by eliminating or reducing exposure to mercury and mercury compounds. To that end, many governments and private groups have made efforts to regulate heavily the use of mercury, or to issue advisories about its use. For example, the export from the european union of mercury and some mercury compounds has been prohibited since the 15th of march, 2010. 43] the variability among regulations and advisories is at times confusing for the lay person as well as of mercury tional safety and health tional g (not to exceed). And drug m allowable nmental protection m contaminant united states environmental protection agency (epa) issued recommendations in 2004 regarding exposure to mercury in fish and shellfish. 45] the epa also developed the "fish kids" awareness campaign for children and young adults [46] on account of the greater impact of mercury exposure to that ng spilled mercury[edit]. 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. 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. Therapy for acute inorganic mercury poisoning can be done with dmsa, 2,3-dimercapto-1-propanesulfonic acid (dmps), d-penicillamine (dpcn), or dimercaprol (bal). However, several studies found no clear clinical benefit from dmsa treatment for poisoning due to mercury vapor. 48] 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. 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. Although it has been hypothesized that frequent low dosages of ala may have potential as a mercury chelator, studies in rats have been contradictory. 49] glutathione and n-acetylcysteine (nac) are recommended by some physicians, but have been shown to increase mercury concentrations in the kidneys and the brain. Findings have demonstrated an interaction between selenium and methylmercury, but epidemiological studies have found little evidence that selenium helps to protect against the adverse effects of methylmercury. Of the toxic effects of mercury are partially or wholly reversible, either through specific therapy or through natural elimination of the metal after exposure has been discontinued. 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. The epa has classified mercuric chloride and methyl mercury as possible human carcinogens (atsdr, epa). May be measured in blood or urine to confirm a diagnosis of poisoning in hospitalized people or to assist in the forensic investigation in a case of fatal overdosage. 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. Chinese emperors and other chinese nobles are known or suspected to have died or been sickened by mercury poisoning after alchemists administered them "elixirs" to promote health, longevity, or immortality that contained either elemental mercury or (more commonly) cinnabar. Among the most prominent examples:The first emperor of unified china, qin shi huang, it is reported, died of ingesting mercury pills that were intended to give him eternal life. 57] concerns that the prescription was having ill effects on the emperor's health and sanity were waved off by the imperial alchemists, who cited to medical texts listing a number of the emperor's conditions (including itching, formication, swelling, and muscle weakness), today recognized as signs and symptoms of mercury poisoning, as evidence that the elixir was effectively treating the emperor's latent ailments. 57] xuānzong became irritable and paranoid, and seems to have ultimately died from the poisoning. 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 central america before being shipped back to spain. 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. Phrase mad as a hatter is likely a reference to mercury poisoning among milliners (so-called "mad hatter disease"), as mercury-based compounds were once used in the manufacture of felt hats in the 18th and 19th century. 1810, two british ships, hms triumph and hms phipps, salvaged a large load of elemental mercury from a wrecked spanish vessel near cadiz, spain. Years, including the early part of his presidency, abraham lincoln took a common medicine of his time called "blue mass," which contained significant amounts of september 5, 1920, silent movie actress olive thomas ingested mercury capsules dissolved in an alcoholic solution at the hotel ritz in paris. Her husband, jack pickford (the brother of mary pickford), had syphilis, and the mercury was used as a treatment of the venereal disease at the time. She died a few days later at the american hospital in early scientific study of mercury poisoning was in 1923–6 by the german inorganic chemist, alfred stock, who himself became poisoned, together with his colleagues, by breathing mercury vapor that was being released by his laboratory equipment—diffusion pumps, float valves, and manometers—all of which contained mercury, and also from mercury that had been accidentally spilt and remained in cracks in the linoleum floor covering. He published a number of papers on mercury poisoning, founded a committee in berlin to study cases of possible mercury poisoning, and introduced the term micromercurialism. Term hunter-russell syndrome derives from a study of mercury poisoning among workers in a seed packing factory in norwich, england in the late 1930s who breathed methylmercury that was being used as a seed disinfectant and preservative. Of methylmercury poisoning occurred in several places in japan during the 1950s due to industrial discharges of mercury into rivers and coastal waters.

Poisoning of two first nation communities in ontario, canada occurred in the late 1960's due to industrial chemical waste released into the waterways and read mercury poisoning occurred in rural iraq in 1971–1972, when grain treated with a methylmercury-based fungicide that was intended for planting only was used by the rural population to make bread, causing at least 6530 cases of mercury poisoning and at least 459 deaths (see basra poison grain disaster). August 14, 1996, karen wetterhahn, a chemistry professor working at dartmouth college, spilled a small amount of dimethylmercury on her latex glove. She began experiencing the symptoms of mercury poisoning five months later and, despite aggressive chelation therapy, died a few months later from brain malfunction due to mercury intoxication. April 2000, alan chmurny attempted to kill a former employee, marta bradley, by pouring mercury into the ventilation system of her car. 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. December 2008, actor jeremy piven was diagnosed with mercury poisoning possibly resulting from eating sushi twice a day for twenty years or herbal remedies he was also taking. India, a study by centre for science and environment and indian institute of toxicology research has found that in the country's energy capital singrauli, mercury is slowly entering people's homes, food, water and even blood. More details on this topic, see ile 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. Is difficult to diagnose, "it is most often postulated that the etiology of this syndrome is an idiosyncratic hypersensitivity reaction to mercury because of the lack of correlation with mercury levels, many of the symptoms resemble recognized mercury poisoning. More details on this topic, see mercury_(element) § y was once prescribed as a purgative. See calomel (mercurous chloride), and mercuric more details on this topic, see thiomersal 1999, the centers for disease control (cdc) and the american academy of pediatrics (aap) asked vaccine makers to remove the organomercury compound thiomersal (spelled "thimerosal" in the us) from vaccines as quickly as possible, and thiomersal has been phased out of us and european vaccines, except for some preparations of influenza vaccine. More details on this topic, see dental amalgam amalgam is a possible cause of low-level mercury poisoning due to its use in dental fillings. Discussion on the topic includes debates on whether amalgam should be used, with critics arguing that its toxic effects make it skin whitening products contain the toxic mercury(ii) chloride as the active ingredient. 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. Mercury in bulbs is typically present as either elemental mercury liquid, vapor, or both, since the liquid evaporates at ambient temperature. 90] when broken indoors, bulbs may emit sufficient mercury vapor to present health concerns, and the u. 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. In 2008, russian lawyer karinna moskalenko claimed to have been poisoned by mercury left in her car,[93] while in 2010 journalists viktor kalashnikov and marina kalashnikova accused russia's fsb of trying to poison them.

Mercury is released into the air by, among other practices, the burning of hazardous material and the mishandling of mercury products. Mercury in the air then settles into water or onto land where it can be washed into rganisms in the water change this mercury into methylmercury, a highly toxic form of mercury that builds up in fish, shellfish, and animals that eat fish. The levels of methylmercury in fish and shellfish depend on what they eat and how long they common sources of exposure include household products that contain mercury, such as skin-lightening creams, antiseptic creams, and ointments, and broken products that contained metallic mercury. The most common of these products are mercury fever thermometers and compact florescent light bulbs (cfls). This is particularly dangerous in warm or poorly-ventilated indoor re to high levels of mercury can harm the brain, heart, kidneys, lungs, and immune system of people of all ages. High levels of methylmercury in the bloodstream of unborn babies and young children have impaired cognitive thinking, memory, attention, language, and fine motor and visual spatial skills. Given the effects of mercury exposure on fetuses, pregnant women and women who are planning pregnancies should make special considerations before eating addition to age, several factors affect the severity of health effects from mercury exposure. These include the form of mercury an individual is exposed to (methylmercury and metallic mercury vapors are most harmful); the amount of mercury an individual is exposed to; the duration of exposure; and the route of exposure (inhalation, ingestion, skin contact, etc.

Replace your mercury thermometers with non-mercury alternatives, such as digital thermometers and disposable temperature strips. Be sure to follow proper recycling and disposal precautions when thermometers and other products containing mercury breakproper clean-up procedures should be followed if a mercury fever thermometer breaks or a compact florescent light bulb breaks to ensure that mercury does not 't eat fish with elevated levels of eating types of fish which tend to have higher levels of mercury and fish that lived in mercury contaminated areas, - like urban ponds.
