| Gefahrenübersicht | Mercurycombines with other elements, such as chlorine, sulfur, or oxygen, to form inorganic mercury compounds or "salts", which are usually white powders or crystals. Mercury also combines with carbon to make organic mercury compounds. The most common one, methylmercury, is produced mainly by microscopic organisms in the water and soil. More mercury in the environment can increase the amounts of methylmercury that these small organisms make.Metallic Mercuryis a dense liquid that vaporizes easily at room temperature. Metallic mercury is not easily absorbed into unbroken skin. However, it vaporizes, even at room temperature. The higher the temperature, the more vapors are released. Mercury vapors are colorless and odorless, though they can be seen with the aid of an ultraviolet light.Metallic mercury is used to produce chlorine gas and caustic soda, and is also used in thermometers, dental fillings, and batteries. Mercury salts are sometimes used in skin lightening creams and as antiseptic creams and ointments.Elemental liquid mercury is poorly absorbed from the GI tract, and it is considered nontoxic by ingestion in patients with normal GI anatomy and motility. Elemental mercury vapor is toxic predominantly to the lung and central nervous system. Pneumonitis can result from exposure to high concentrations of heated mercury vapor in a confined space. Otherwise, inhalation of mercury vapor is toxic over a period of months or years when air levels exceed 0.05-0.2 mg/m3. The main adverse effects after chronic exposure to mercury vapor are neuropsychiatric and include tremor, memory loss, insomnia, anorexia, irritability, and other mood changes. Kidney disease and peripheral neuropathy have been rarely reported after chronic exposure to mercury vapor. Acrodynia is a rare idiosyncratic disorder reported in children after mercury vapor exposure. [Olson, p. 305-7] Data is limited on the fetal effects of mercury in forms other than methyl mercury. Experimental animals exposed to high doses of mercury vapor and salts have increased developmental abnormalities. [ATSDR Case Studies #29] Mercury may produce slight hepatic injury in experimental animals. [Zimmerman, p. 419] Background levels of mercury are generally <10 ug/L for whole blood and <20 ug/L for urine. Regarding dental amalgams as a source of mercury vapor, occupational exposures can be controlled and personal exposures from fillings are insignificant. [Goldfrank, p. 1302, 1304] Exposure to metallic mercury, for example from amalgam teeth fillings and other dental exposure, may give rise to sensitization. [Nordberg, p. 1041] See Mercury, inorganic compounds. |

Sumps in the underfloor drainage systems were used to collect Hg from spills which were flushed into them, but the design of these was not highly effective. To reduce Hg losses via this route, water use for this purpose is now kept to a minimum necessity and the sump discharge is either fed into the brine circuit or treated for Hg removal prior to discharge.A small aspirator-driven vacuum trap with a "mercury sweeper", an amalgamated copper roller operating in a small, tin-plate "dustpan" or "mercury scoop" is effective. This can be followed, if necessary, (and with an appropriate choice, for the surface on which the spill took place) by washes with dilute nitric acid (approx 1 M), concentrated sulfuric acid, or bleach washes, and then by clear water rinses.For more Cleanup Methods (Complete) data for MERCURY, ELEMENTAL (11 total), please visit the HSDB record page. |

It is only slowly absorbed through the skin, although it may cause skin and eye irritation. Elemental mercury droplets may be absorbed through eye contact.

| Toxizitätsübersicht | IDENTIFICATION: In its elemental form, mercury is a heavy silvery liquid at room temperature and has a very high vapour pressure. Mercury vapor is more soluble in plasma, whole blood, and hemoglobin than in distilled water, where it dissolves only slightly. The major natural sources of mercury are degassing of the earth's crust, emissions from volcanoes, and evaporation from natural bodies of water. (The world-wide mining of mercury is estimated to yield about 10,000 tons per year. The activities lead to some losses of mercury and direct discharges to the atmosphere). Other important sources are fossil fuel combustion, metal sulfide ore smelting, gold refining, cement production, refuse incineration, and industrial applications of metals. A major use of mercury is as a cathode in the electrolysis of sodium chloride. Mercury is used in the electrical industry, in control instruments in the home and industry, and in laboratory and medical instruments. A very large amount of mercury is used for the extraction of gold. Dental silver amalgam for tooth filling contains large amounts of mercury. Use of skin-lightening soap and creams can give rise to substantial mercury exposure. Occupational exposure to inorganic mercury has been investigated in chloralkali plants, mercury mines, thermometer factories, refineries, and in dental clinics. High mercury levels have been reported for all these occupational exposure situations, although levels vary according to work environment conditions. HUMAN EXPOSURE: The general population is primarily exposed to mercury through the diet and dental amalgam. Acute inhalation exposure to mercury vapor may be followed by chest pains, dyspnea, coughing, hemoptysis, and sometimes interstitial pneumonitis leading to death. (The ingestion of mercuric compounds, in particular mercuric chloride, has caused ulcerative gastroenteritis and acute tubular necrosis causing death from anuria where dialysis was not available). The central nervous system is the critical organ for mercury vapor exposure. Subacute exposure has given rise to psychotic reactions characterized by delerium, hallucinations, and suicidal tendency. Occupational exposure has resulted in erethism as the principal feature of a broad ranging functional disturbance. The kidney is the critical organ following the ingestion of inorganic divalent mercury salts. Occupational exposure to metallic mercury has long been associated with the development of proteinuria. Both metallic mercury vapor and mercury compounds have given rise to contact dermatitis. Mercurial pharmaceuticals have been responsible for Pink disease (acrodynia) in children, and mercury vapor exposure may be a cause of "Kawasaki" disease. Results of both human and animal studies indicate that about 80% of inhaled metallic mercury vapour is retained by the body, whereas liquid metallic mercury is poorly absorbed via the gastrointestinal tract. ANIMAL STUDIES: Evidence of damage to brain, kidney, heart, and lungs have been reported in rabbits exposed acutely to metallic mercury vapor at certain concentrations. Both reversible and irreversible toxic effects may be caused by mercury and its compounds. In two studies, tremor and behavioural effects were observed in rabbits and rats after several weeks of exposure to metallic mercury vapour. Depending upon the animal strain tested, either auto-immunity or immunosuppression is observed. The most sensitive adverse effect caused by mercuric mercury is the formation of mercuric-mercury-induced auto-immune glomerulonephritis. Mercuric chloride was found to induce gene mutations in mouse lymphoma cells and DNA damage in rat and mouse fibroblasts. The World Health Organization reported no evidence that inorganic mercury is carcinogenic. The neurotoxic effect seen after exposure to metallic mercury vapour is attributable to the divalent mercury ion formed through oxidation in the brain tissue. Significantly more mercury is transported to the brain of mice and monkeys after the inhalation of elemental mercury than after the intravenous injection of equivalent doses of the mercuric form. |

| Average Daily Intake | Assuming an ambient air level of 50 ng/cu m, the average daily intake of metallic mercury vapor would amount to 1 ug/day due to inhalation. ... The average daily intake of those sub-groups of the general population living in specially polluted areas is difficult to estimate with any accuracy. ... Daily intake from occupational exposure is almost impossible to estimate because of the wide variation in exposure conditions in industry. |

Acute toxicity may also cause kidney damage (sometimes severe) and kidney failure, rapid heart rate (tachycardia), and high blood pressure (hypertension).
