反応プロフィール

MERCURY forms an explosive acelylide when mixed with acetylene. Can form explosive compounds with ammonia (a residue resulting from such a reaction exploded when an attempt was made to clean MERCURY off a steel rod [Chem. Eng. News 25:2138. 1947]. Chlorine dioxide (also other oxidants, such as: chlorine, bromine, nitric acid, performic acid), and MERCURY explode when mixed [Mellor 2, Supp. 1:381. 1956]. Methyl azide in the presence of MERCURY is potentially explosive [Can. J. Chem. 41:1048. 1963]. Ground mixtures of sodium carbide and MERCURY can react vigorously [Mellor 5:848. 1946-47]. Ammonia forms explosive compounds with gold, MERCURY, or silver. (Eggeman, Tim. mmonia Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. 2001.).

危険性

Central nervous system impairment, peripheral nervous system impairment, and kidney damage. (1) Mercury, metallic: Highly toxic by skin absorption and inhalation of fume or vapor, absorbed by respiratory and intestinal tract. FDA permits zero addition to

健康ハザード

Mercury is a non-specific toxin, attacking many of the body s systems. At low levels of exposure, symptoms are mainly related to nerve and brain function and include memory loss, mood instability, tremor, and other stress-like symptoms: poor coordination, headache, and visual and hearing problems. Recently, reproductive health has been shown to be affected, with abnormalities in menstrual cycle, poor outcome of pregnancy, and subfertility in both men and women. The immune system is also damaged by mercury exposure.

健康ハザード

ngestion is largely without effects. Inhalation of high concentrations of mercury causes severe respiratory irritation, digestive disturbances, and marked kidney damage. There are no warning properties for exposure to mercury vapor, which is colorless, odorless, and tasteless.
Toxicity caused by repeated or prolonged exposure to mercury vapor or liquid is characterized by emotional disturbances, inflammation of the mouth and gums, general fatigue, memory loss, headaches, tremors, anorexia, and weight loss. Skin absorption of mercury and mercury vapor adds to the toxic effects of vapor inhalation. At low levels the onset of symptoms is insidious; fine tremors of the hand, eyelids, lips, and tongue are often the presenting complaints. Mercury has been reported to be capable of causing sensitization dermatitis. Mercury has not been shown to be a human carcinogen or reproductive toxin

健康ハザード

Elemental mercury and its inorganic salts,as well as organomercury compounds, areall highly toxic substances. The elementhas a vapor pressure of 0.0018 torr at 25°C(77°F), which is high enough to make it asevere inhalation hazard. Exposure to mercuryvapors at high concentrations for ashort period can cause bronchitis, pneumonitis,coughing, chest pain, respiratory distress,salivation, and diarrhea. The toxic symptomsdue to its effects on the central nervous systeminclude tremor, insomnia, depression, and irritability.A 4- hour exposure to mercury vaporsat a concentration of about 30 mg/m3 in airproduced damage in the kidneys, liver, lungs,and brain in rabbits (ACGIH 1989). Elementalmercury is rapidly oxidized to Hg(II) in redblood cells. Prior to its oxidized and accumulates(Manahan 1989). Mercury(II) accumulatesin the kidneys.
The toxicity of mercury depends on itschemical form the target organs, symptomsand signs may differ with exposureto elemental mercury its inorganic compoundsor organic mercury. The toxicities of mercurycompounds show significant variation withsolubility. Less soluble mercurous compoundsare relatively less toxic than themore soluble mercuric salts. The latter compoundsare highly toxic ingestion. Chroniceffects due to Hg(II) ions are inflammationof the muth, salivation, loose teeth, muscletremors, jerky gait, depression, irritability,and nervousness (Hodgson et al. 1988). TheHg2C ions have an affinity for sulfhydrylgroups ( SH) in proteins, enzymes, serumalbumin, and hemoglobin to form complexes,thereby causing enzyme inhibition.Cycteine, penicillamine, and 2,3-dimercapto-1-propanol are effective antidotes againstmercury(II) poisoning. Also reported are theother sulfur antidotes; unithiol ,BAL , and D-penicillamine [52-67-5] (Softova et al. 1984). These substancescan form chelates with mercury and excreteout in the urine, thus exhibiting a protectiveeffect against mercury-induced renaldamage. N-Benzyl-D-glucamine is anotherchelating agent that has shown protectiveaction against renal toxicity of inorganic mercuryin rats (Kojima et al. 1989).
Endo et al. (2003) investigated therenal toxicity in rats caused by a singleoral administration of mercury-contaminatedboiled whale livers that contained both theinorganic mercury and dimethylmercury. Theconcentration of mercury in the rat kidneyincreased markedly after the dose, so alsothe urinary excretion of N-acetyl-beta-Dglucosanidase,albumin, and sodium. Also,the concentrations of creatinine, potassium,and phosphorus in the serum and the lactatedehydrogenase activity increased. The studyshowed that the renal toxicity was causedby inorganic mercury and that the humanconsumption of boiled whale liver couldcause acute intoxication from contaminatedinorganic mercury.
Several studies have been carried out todetermine the adverse health effects fromhuman exposure to mercury from dentalamalgam (Ratcliffe et al. 1996; Krupa 2004).However, all findings are inconclusive. Theevidences found are insufficient to drawa link between dental mercury fillingsand human health problems except in rareinstances of allergic reactions.

安全性プロファイル

Poison by inhalation. Human systemic effects by inhalation: wakefulness, muscle weakness, anorexia, headache, tinnitus, hypermotihty, darrhea, liver changes, dermatitis, fever. An experimental teratogen. Experimental reproductive effects. Questionable carcinogen with experimental tumorigenic data. Human mutation data reported. Used in dental applications, electronics, and chemical synthesis. bromopropyne, alkynes + silver perchlorate, ethylene oxide, lithium, methylsilane + oxygen (explodes when shaken), peroxyformic acid, chlorine dioxide, tetracarbonylnickel + oxygen. May react with ammonia to form an explosive product. Mixtures with methyl azide are shockand spark-sensitive explosives. The vapor iptes on contact with boron diiodophosphide. Reacts violently with acetylenic compounds (e.g., acetylene, sodmm acetylide, 2-butyne-l,4 do1 + acid), metals (e.g., aluminum, calcium, potassium, sodium, rubidium, exothermic formation of amalgams), Cl2, ClO2, CH3N3, NazCz, nitromethane. Incompatible with methyl azide, oxidants. When heated to decomposition it emits toxic fumes of Hg. See also MERCURY COMPOUNDS.

職業ばく露

Mercury is used as a catalyst, in dental applications; and in pharmaceuticals; as a liquid cathode in cells for the electrolytic production of caustic and chlorine. It is used in electrical apparatus (lamps, rectifiers, and batteries) and in control instruments (switches, thermometers, and barometers)

貯蔵

Precautions should be taken to prevent spills of mercury because drops of the liquid metal can easily become lodged in floor cracks, behind cabinets, and equipment, etc., with the result that the mercury vapor concentration in the laboratory may then exceed the safe and allowable limits. Containers of mercury should be kept tightly sealed and stored in secondary containers (such as a plastic pan or tray) in a well-ventilated area. When breakage of instruments or apparatus containing significant quantities of Hg is possible, the equipment should be placed in a plastic tray or pan that is large enough to contain the mercury in the event of an accident. Transfers of mercury between containers should be carried out in a fume hood over a tray or pan to confine any spills.

輸送方法

UN2809 Mercury, Hazard class: 8; Labels: 8-Corrosive material, 6.1-Poisonous material

純化方法

After air has been bubbled through mercury for several hours to oxidise metallic impurities, it is filtered to remove coarser particles of oxide and dirt, then sprayed through a 4-ft column containing 10% HNO3. It is washed with distilled water, dried with filter paper and distilled under vacuum. [Schenk in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p8 1963.]

不和合性

Heating mercury causes the formation of toxic mercury oxide fumes. Reacts violently with alkali metals; acetylene, azides, ammonia gas; chlorine, chlorine dioxide; many acids; most metals; ground mixtures of sodium carbide, and ethylene oxide. Contact with methyl azide forms shock- and spark-sensitive explosives. Attacks copper and many other metals, forming amalgams

廃棄物の処理

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. Accumulate for purification and re-use if possible. Mercury vapors may be adsorbed or treated with sulfide solutions and then sent to mercury recovery operations
