Elemental mercury exposure:peripheral neurotoxicity . Thus, there is evidence that mercury has been utilized throughout antiquity. Neurology 1982; 32:1168–74. Samples of liquid paint, vacuum-cleaner dust, and urine were analyzed by cold-vapor atomic absorption. The model r2 was 0.72 (Table 2). Concise summaries and expert physician commentary that busy clinicians need to enhance patient care. Our study showed that significant exposure to mercury occurred in persons exposed to Mercury Paint Company paint that contained a median concentration of mercury 2 1/2 times the previously recommended limit. In the body, phenyl-mercuric acetate is rapidly broken down to form inorganic mercury. London: Burlinghouse, 1982:94–204. Miller JM, Chaffin DB, Smith RG. Median Urinary Mercury Concentrations in Persons Exposed to Paint Containing Mercury and in Those Not Exposed, According to Age. T… Button Cell Batteries Mercury in house paint as a cause of acrodynia: effect of therapy with N-acetyl-D,L-penicillamine . Biological monitoring of toxic metals. 20. Curtis HA, Ferguson SD, Kell RL, Samuel AH. Castner discovered that mercury could be used in the chlor-alkali process to produce chlorine and caustic soda. 11. In preparing this blog post, we used information from Brooks’s 2012 chapter in Mercury in the Environment and Nriagu’s 1979 The Biogeochemistry of Mercury in the Environment, unless otherwise noted. 27. Washington, D.C.: SRI International, 1988. A comparison of four personal sampling methods for the determination of mercury vapor . It is surprising how many uses there are and have been for mercury. NEW! Washington, D.C.: American Chemical Society, 1972. Environmental chemistry. The molecular weight of mercury is 201, and that of creatinine is 113. Among the exposed households, the mercury concentrations in the air were significantly higher in the homes that had had more rooms painted, had been painted more recently, had windows open for fewer hours a day at the time the questionnaire was administered, and were newer. Young children may be at increased risk, since vapors containing mercury are heavier than indoor air and settle toward the floor.42. Smith PJ, Langolf GD, Goldberg J. . Samples of remaining liquid paint, indoor air, vacuum-cleaner-bag dust, and first morning urine were collected to analyze their total mercury content. It is used in the form of gaseous vapors in vapor lamps, neon signs, and fluorescent lamps. It is the only metal to be liquid at room temperature. Mercury easily forms alloys, called amalgams, with other metals such as gold, silver and tin. Of note, individuals who made felt hats displayed signs of dementia as a result of mercury poisoning. High fructose corn syrup is used in food products to enhance shelf life. Study Group of Minamata Disease. Samples of indoor air were collected in Hopcalite tubes with a personal air-sampling pump (Gilian) that operated for 12 hours at a flow rate of 0.5 liter per minute. Another black mark for high fructose corn syrup. Aristotle is credited with the oldest known written record of mercury (in an academic text dating back to sometime during the 4th century BCE), in which he referred to it as “fluid silver” and “quicksilver.” This academic text conveyed what alchemists of his day believed: that mercury was the component in all metals that gave them their “metal-ness.” At that time, it was used in ceremonies and to treat skin disorders. Did Mercury in “Little Blue Pills” Make Abraham Lincoln Erratic? ), MERCURY, in both its organic and inorganic forms, can be toxic to humans. Littlejohn D, Fell GS, Ottaway JM. This mercury cycles through the deep earth, the atmosphere, the terrestrial reservoir, and various water bodies on timescales that vary from less than a year to tens of thousands of years. A pilot study was conducted to determine if high fructose corn syrup contains mercury, a toxic metal historically used as an anti-microbial. Fawer RF, de Ribaupierre Y, Guillemin MP, Berode M, Lob M. . Clin Chem 1976; 22:1719–23. Despite the opening of new mines in recent decades, a report from the EU predicts that recycling of mercury from products and by-products could help meet the mercury demand and further reduce direct mining of mercury. Mercury (Hg) has a unique combination of physical properties. Wood RW, Weiss AB, Wiess B. . . 34. Time-weighted average (TWA) mercury exposures and urine mercury levels . With respect to total mercury exposure, it may be necessary to account for this source of mercury in the diet of children and sensitive populations. In our study, urinary mercury concentrations correlated poorly with the levels of mercury in the air. Method #245.5. 37. And during WWII, the Ruben-Mallory battery (mercury dry-cell battery) was invented and widely used. 1). 1. . No mercury was detected in the air samples from the unexposed households. However, today the use of mercury is being phased out for safer mercury-free products. The samples were found to contain levels of mercury ranging from below a detection limit of 0.005 to 0.570 micrograms mercury per gram of high fructose corn syrup. Methods for chemical analysis of water and wastes. Symptoms depend upon the type, dose, method, and duration of exposure. These “Mad Hatters” were referred to by Lewis Carroll in his book Alice in Wonderland. Urinary mercury concentrations, both adjusted and unadjusted, were significantly higher among the exposed persons than among the unexposed persons (P<0.001) (Fig. Mercury concentrations measured in the air in seven buildings ranged from 8.0 nmol per cubic meter 7 days after painting to 0.35 nmol per cubic meter after 33 months.37 In another study, two hours after the application of paint containing 234 nmol of mercury per liter, a concentration of 18.9 nmol per cubic meter was detected in a room; after eight days, 6.5 nmol per cubic meter remained. Persons on the list were called until 19 families meeting the above criteria had been identified. Thus, proper ventilation during painting must be ensured. Paint samples were obtained from the homes of six of the unexposed families (60 percent); no mercury was detected in any of these samples. Tests of the interior paint used in the boy's house showed it had 900 parts per million of mercury, three times the legal limit. Your email address will not be published. In 1891, Thomas Edison’s incandescent lamp contained mercury (to this day compact fluorescent light bulbs have mercury added to them.) Acrodynia developed in a five-year-old boy with a urinary mercury concentration of 449 nmol per liter associated with paint containing 997 nmol of mercury per liter.16 Acrodynia has been reported in people with urinary mercury concentrations of 249 nmol per liter,14 a value comparable to the concentrations found among exposed children in our study. The few changes that have been experienced over the years have mostly come from the few meteors that collide with the planet. Br J Ind Med 1982; 39:136–9. 2. HELP! Am Ind Hyg Assoc J 1978; 39:976–84. These uses prompt mining and other ways of making mercury available. The urinary mercury concentrations were higher, however, among exposed persons who were younger, applied the paint themselves, spent more hours in the home, and lived in homes painted less recently. The heavy metal additive also decreases the amount of time that the paint takes to dry, makes the paint more durable, and causes the paint to be more moisture resistant. Washington, D.C.: Environmental Protection Agency, 1976. Mercury poisoning refers to a toxicity from mercury consumption. 77–157.). The Kruskal—Wallis test was used when more than two groups were compared. Albers JW, Cavender GD, Levine SP, Langolf GD. How is mercury used in paint? Samples were not obtained from two exposed adults who were traveling on business, nor from seven exposed children five years of age or younger who were unable or unwilling to provide samples. 28. The use of mercury in paint has continued into the modern area, although in recent history, mercury was added as a fungicide rather than for its chromatic properties. Code of federal regulations: title 29, part 1910.1000.

Charleston, Tenn.: Olin Chemical Company, 1988. 2. 22. They are an amalgam of mercury with another element. 246. High fructose corn syrup samples were collected from three different manufacturers and analyzed for total mercury. As with most elements, there is a fixed amount of mercury on the planet. 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 It’s also common in many household items such as fluorescent lights, batteries, and latex paint. Products become potentially hazardous when they contain chemicals that can endanger human health or the environment if not properly used, stored, and/or disposed. To extract mercury from cinnabar, the mineral is heated. MMWR 1990; 39:125–6. None of the other sources of mercury exposure we evaluated accounted for the differences. Ure AM, Berrow ML. Merbromin, another organic mercury compound, is used as an antiseptic. Arch Environ Health 1973; 26:249–52. In adults, chronic exposure to mercury vapors can cause nerve-conduction delays, tremor, insomnia, loss of appetite, and irritability (4,7). Mercury is a type of toxic metal that comes in different forms within the environment. 39. Fourteen exposed persons (22 percent) had urinary mercury concentrations ≥100 nmol per liter, and 45 exposed persons (69 percent) had concentrations ≥50 nmol per liter. It wasn’t until 1991 that the use of mercury in paint was phased out in the US. Preliminary health assessment. 41. // Nation's Health;May/Jun94, Vol. To determine whether the recent use of that brand of paint containing phenylmercuric acetate was associated with elevated indoor-air and urinary mercury concentrations, we studied 74 "exposed" persons living in 19 homes recently painted with the brand and 28 "unexposed" persons living in 10 homes not recently painted with paint containing mercury. Mercury is a toxic substance that can cause neurological disorders and damage to the nervous system. Should You Worry About Mercury in Your Silver Dental Fillings? ), Center for Environmental Health and Injury Control, Centers for Disease Control, Atlanta; the Environmental Response Branch, Environmental Protection Agency, Edison, N.J. Exposure to organic mercury during the late 1950s in Minamata, Japan, caused 41 deaths and at least 30 cases of infantile cerebral palsy.1 In the 1940s, inorganic mercury added to teething powders caused numerous cases of acrodynia, a form of childhood mercury poisoning.2 Despite its known toxicity, mercury is still used in many household products, such as latex (water-based) paint. 23. The paint samples from the homes of exposed persons contained a median of 3.8 mmol of mercury per liter, and air samples from the homes had a median mercury content of 10.0 nmol per cubic meter (range, <0.5 to 49.9).

J Occup Med 1973; 15:501–8. 24 Issue 5, p5 . In 1835, polyvinyl chloride (PVC) was first produced, the original synthesis of which relied on mercury as a catalyst. The median age was 24 years (range, <1 to 72) in the exposed group and 30 years (range, 3 to 48) in the unexposed group. They used mercury as a pigment in their paint; mercury-containing paint has been found in Roman homes buried by the volcanic ash of Mount Vesuvius in 79CE. The mercury surrounds the gold, forming shiny pellets that workers then burn. . We have reported the results of the urinary mercury determinations both unadjusted (nanomoles per liter of urine) and adjusted for the creatinine concentration of the urine (nanomoles per millimole of creatinine). Between 1850 and the 1960’s, the Santa Barbara mine ceased production and mercury mining began in two other regions: in Monte Amiata, Italy, and throughout California in the United States. Hirschman SZ, Feingold M, Boylen G. . In dentistry amalgam fillings are used for repairing cavities. 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. 1 Answer.

DOI: 10.1056/NEJM199010183231603, Tap into groundbreaking research and clinically relevant insights. We performed multiple linear-regression analyses to identify factors that contributed significantly to the concentrations of mercury in the air in the 19 exposed homes and to identify factors that contributed significantly to the variance in the adjusted urinary mercury concentrations among the 65 exposed people who provided first morning urine samples.15 We included all factors in the initial regression model that were found to be significantly associated (P≤0.05) with the variable of interest on univariate analysis, as well as any other factors we thought important. Kumamoto, Japan; Kumamoto University, 1968. Unfortunate the element is so fascinating to look and has some truly extraordinary uses. Many paint companies have used phenylmercuric acetate as a preservative to prolong the shelf life of interior latex paint. 14. Samples of vacuum-cleaner-bag dust were obtained from seven exposed households (37 percent) and three unexposed households (30 percent). Mercury processing, preparation of the ore for use in various products. Mercury readily forms alloys with other metals, and this makes it useful in processing gold and silver. I am a PhD candidate in the Engineering Systems Division at MIT. 36. Jacobs MB, Goldwater LJ. This means you can subject the mercury in a thermometer to heat and it will react.

The source of mercury in the unexposed households may have been dust from paint containing mercury released from deteriorating surfaces (as is the case with leaded paint) or soil containing mercury that was brought into the home (the mercury content of soil in the United States ranges from 0.05 to 22.9 nmol per kilogram).43 Children may be more exposed to soil and dust particles containing mercury than adults, since children are more apt to have contact with these particles on the floor and to put hands, feet, and objects in their mouths. Vol. Opening all windows and doors decreased the concentration to 1.5 nmol per cubic meter; however, if the doors and windows were then closed, the concentration of mercury in the air returned to the earlier (unventilated) value within three hours.38 The investigators concluded that mercury would be emitted at a rate of 499 nmol per day for 7 1/2 years. Surveillance of workers exposed to mercury vapour: validation of a previously proposed biological threshold limit value for mercury concentration in urine . 19. They used mercury as a pigment in their paint. By the 1960s, the production of electrical apparati, caustic soda, and chlorine accounted for over 50% of mercury uses. Neurophysiological and neuropsychological function in mercury-exposed dentists . New York: Plenum Press, 1988. 13. Mercury exposure from house paint — a controlled study on humans . In 1859, a new organization was formed as a result of the internal strife over the use of mercury in dentistry — the American Dental Association. One unexposed person was excluded from analysis because she had collected paint samples from exposed homes. Langolf GD, Chaffin DB, Henderson R, Whittle HP. Vacuum-cleaner-dust samples were sifted through a 60-mesh sieve, and the resulting dust was analyzed. Leg cramps, a generalized rash, pruritus, sweating, tachycardia, an intermittent low-grade fever, marked personality change, erythema and desquamation of the hands, feet, and nose, weakness of the pelvic and pectoral girdles, and lower-extremity nerve dysfunction developed sequentially. Rosenman KD, Valciukas JA, Glickman L, Meyers BR, Cinotti A. . Mercury has been used in dental fillings until it was replaced with safer materials.
