Reacts with air; Reacts with water to form explosive hydrogen gas and corrosive lithium hydroxide; [CHEMINFO] Lithium poisoning is most common in patients in long-term treatment with renal impairment. The usual daily dose is 300 to 2400 mg. The therapeutic serum level is 0.6-1.2 mEq/L. Lithium intoxication may occur in lithium-treated patients who develop acute gastroenteritis, take thiazide diuretics, or use NSAIDs or ACE inhibitors. Common symptoms of lithium intoxication are lethargy, weakness, slurred speech, ataxia, tremor, and myoclonic jerks which may progress to delirium, seizures, hyperthermia, and coma. Diagnosis is supported by an elevated lithium level, but the degree of elevation does not predict the degree of toxicity. [Olson, p. 293-5] There is evidence from pharmacologic use that lithium is nephrotoxic. [Rosenstock, p. 572] Not being protein bound, Li is rapidly eliminated by the kidneys, with almost no tissue accumulation. Side effects in patients treated with lithium include reduced urinary concentration capacity, hypothyroidism, and neurotoxicity.

General First Aid:
Corrosive ... Water reactive ... Evolves hydrogen and ignites on contact with water.
Sodium carbonate and sodium chloride are unsuitable to use as extinguishers for lithium fires, since burning lithium will liberate the more reactive sodium in contact with them.
Liquid lithium is readily ignited and reacts with most extinguishing agents, including water, carbon tetrachloride and carbon dioxide.
Since lithium will burn in oxygen, nitrogen or carbon dioxide, and when alight it will remove the combined oxygen in sand, sodium carbonate, etc., it is difficult to extinguish once alight ... Use of normal fire extinguishers (containing water, form, carbon dioxide, halocarbons, dry powders) will either accelerate combustion or cause explosion.
· Wear positive pressure self-contained breathing apparatus (SCBA).
0.2 [mg/m3], inhalable fraction, as Li (except Li and highly irritating lithium compounds, lithium amide, hydride, hydroxide, nitride, oxide, tetrahydroaluminate, and tetrahydroborate)[German Research Foundation (DFG)]
Extinguish lithium fires only with chemicals designed for this purpose.
Use approved Class D extinguishers or smother with dry sand, dry clay, or dry ground limestone. DO NOT use carbon dioxide or halogenated extinguishing agents. DO NOT use water. Violent reaction may result.
If material on fire or involved in fire: Do not use water. Do not use carbon dioxide. Use graphite, soda ash, powdered sodium chloride, or suitable dry powder.
Powdered graphite, lithium chloride, potassium chloride or zirconium silicate are suitable extinguishants.
Store in a cool, dry, well-ventilated location. Separate from water.
Keep under mineral oil or other liquid free from oxygen or water.
Eliminate all ignition sources. Keep water away from release. Shovel into suitable dry container.
Spillage Disposal: Wear eye protection, laboratory coat and nitrile rubber gloves. Cover spill with a 1:1:1 mixture by weight of sodium carbonate or calcium carbonate, clay cat litter (bentonite) and sand. Scoop the mixture into a pail and transport to the fume hood. Slowly and with stirring add to a large quantity of 95% ethanol. Mix and let stand for 24 hours. The solid residue may be treated as normal refuse.
Waste Disposal: Package Lots. Place in a separate labeled container for recycling or disposal by burning. Burn in an open furnace. Use caution and limit to 100 g packages. Small Quantities. Wear eye protection, laboratory coat and nitrile rubber gloves. Work in the fume hood. Equip a 3-necked round-bottom flask with a stirrer, dropping funnel, condenser and heating mantle. Flush the flask with nitrogen and place the lithium (cut in small pieces) in it. Add 30 mL of 95% ethanol per gram of lithium at a rate that causes rapid refluxing. Stirring is started as soon as enough ethanol has been added to make it feasible. The mixture is stirred and heated under reflux until the lithium is dissolved. The heat is turned off, and an equal volume of water is added at a rate that causes no more than mild refluxing. The solution is then cooled, neutralized with 6 M hydrochloric acid (cautiously add a volume of concentrated acid to an equal volume of cold water) and washed down the drain with at least 50 times its volume of water.
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
Liver test abnormalities have been reported to occur in a small proportion of patients on long term therapy with lithium. These abnormalities are usually asymptomatic and transient, reversing even with continuation of medication. Instances of more marked elevations in serum aminotransferases have been reported in patients taking overdoses of lithium, but the other metabolic and systemic effects of lithium overdose generally overshadow hepatic adverse effects. Lithium has not been associated with instances of clinically apparent acute liver injury with jaundice.

Lithium can cause various adverse effects, often correlated with the dosage. The notable adverse effects of lithium include:
IDENTIFICATION AND USE: Elemental lithium is a silver white metal; body centered cubic structure it becomes yellowish on exposure to moist air and it reacts with water. It is soluble in liquid ammonia forming a blue solution. It is used in the manufacture of catalysts for polyolefin plastics; in fuels for aircraft and missiles.It is used in metallurgy, as a degasifier, deoxidizer, desulfurizer; as a grain refiner in non-ferrous metals. Chemical intermediate for butyllithium polymerization catalyst; in alloys with aluminum or magnesium for aerospace uses. It is used in the production of tritium, reducing and hydrogenating agents, alloy hardeners, pharmaceuticals and Grignard reagents. Scavenger and degassifier for stainless and mild steels in molten state, modular iron, soaps and greases, deoxidizer in copper and copper alloys, heat-transfer liquid, storage batteries (with sulfur, selenium, tellurium, and chlorine). Rocket propellants, vitamin A synthesis, silver solders, underwater bouyancy devices, nuclear reactor coolent. HUMAN EXPOSURE AND TOXICITY: Elemental lithium causes severe eye and skin burns. Industrial exposures to lithium may occur during extraction of lithium from its ores, preparation of various lithium compounds, welding, brazing, enameling, and from the use of lithium hydrides. ANIMAL STUDIES: No animal studies could be located.
Due to its narrow therapeutic index, serum levels of lithium exceeding 2 mEq/L are considered toxic, which falls within its therapeutic range. Lithium toxicity can result in interstitial nephritis, arrhythmia, sick sinus syndrome, hypotension, T-wave abnormalities, and bradycardia. In rare instances, toxicity can lead to pseudotumor cerebri and seizures. Notably, there exists no antidote for lithium toxicity. The primary approach to treating lithium toxicity involves hydration and discontinuation of the drug. Administering hydration through normal saline concurrently facilitates lithium excretion. Close monitoring is essential to prevent hypernatremia in patients receiving normal saline. Diuretic use should be avoided for patients on lithium treatment. For mitigating tremors, administering 20 to 30 mg of propranolol twice or thrice daily is recommended.
Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed.
Redness. Skin burns. Pain. Blisters.
Redness. Pain. Severe deep burns.
Abdominal cramps. Abdominal pain. Burning sensation. Nausea. Shock or collapse. Vomiting. Weakness.
Lithium is widely distributed in nature; trace amounts are found in many minerals, in most rocks and soils, and in many natural waters(1). Lithium is a member of the alkali metals and does not occur as the free metal in nature(2). The typical oxidation state of the alkali metals is +1; no other cations are known or expected for the alkali metals(4). Lithium concentrations in the earth's crust are estimated to be 20 to 70 ppm by weight(1); it is the 27th most abundant element(3). Lithium is found in small amounts in nearly all igneous rocks and in the waters of many mineral springs(2). Lepidolite, spodumene, petalite, and amblygonite are the most important lithium containing minerals(2).
NIOSH (NOES Survey 1981-1983) has statistically estimated that 3,455 workers (1,084 of these are female) are potentially exposed to lithium in the US(1).
Industrial exposures to lithium may occur during extraction of lithium from its ores, preparation of various lithium compounds, welding, brazing, enameling, and from the use of lithium hydrides. /Lithium/

Lithium is found in small amounts in nearly all igneous rocks and in the waters of many mineral springs. Lepidolite, spodumene, petalite, and amblygonite are the most important lithium containing minerals. The production and use of lithium compounds in ceramics, glass and primary aluminum production, the manufacture of lubricants and greases, primary and secondary (rechargeable) batteries, the production of synthetic rubber, the manufacture of polyester fiber, the production of antioxidants and antihistamines, as catalysts, and in the treatment of mood disorders may result in the release of lithium compounds to the environment through various waste streams. If release to air lithium compounds should exist in the particulate phase in the ambient atmosphere since the ionic nature of lithium compounds makes them essentially non-volatile. Particulate-phase lithium may be physically removed from the air by wet and dry deposition. The adsorption of lithium was measured on aquifer material; Freundlich coefficients ranged from 4.5 to 5.5. Lithium has been found to sorb slightly to humic soils with a Kp of 4.6 at pH 5. These data indicate that lithium compounds are not expected to adsorb strongly to soils and sediments. Lithium ion would not be expected to undergo oxidation-reduction reactions under environmental conditions, and would exist in its +1 oxidation state either in compounds or as dissolved ions. The ionic nature of lithium compounds makes them essentially non-volatile; lithium compounds would not volatilized from dry soil surfaces. Due to the ionic nature of lithium compounds, volatilization from moist surfaces will not occur. In water, adsorption to suspended solids and sediments is not expected to be important fate processes for lithium compounds. Lithium ions may undergo precipitation, sorption, or ligand exchange reactions in the environment. Due to the ionic nature of most lithium compounds, volatilization from water surfaces will not occur. Bioconcentration is not expected to be an important fate process due to the ionic nature of lithium compounds. Occupational exposure to lithium compounds may occur through inhalation and dermal contact at workplaces where lithium compounds are produced or used. Since lithium is found various environmental media, the general public would be exposed to small amounts of lithium via inhalation of ambient air, ingestion of food and drinking water. (SRC)

Consideration may be given to gastric lavage with a large diameter tube for removal of material and then dilution with large amounts of water. Esophagoscopy may be of assistance in this procedure and to assess extent of damage. Treatment is otherwise symptomatic and supportive. Administration of activated charcoal is not useful because it does not bind to lithium ions and obscures endoscopic findings

説明Lithium is an alkali metal with physiologic actions similar to potassium and sodium. Lithium was discovered as a salt in 1817 by Johan August Arfwedson. It does not occur in nature as a free metal but is found in minerals such as spodumene, petalite, and eucryptite. It is the 27th most abundant element in Earth’s crust. Lithium was used to treat gout, as a salt substitute, and as a major constituent of the soft drink 7-Up before 1950.
天然物の起源Lithium ranks 33rd among the most abundant elements found on Earth. It does not existin pure metallic form in nature because it reacts with water and air. It is always combinedwith other elements in compound forms. These lithium mineral ores make up only about0.0007%, or about 65 ppm, of the Earth’s crust.Lithium is contained in minute amounts in the mineral ores of spodumene, lepidolite, andamblygonite, which are found in the United States and several countries in Europe, Africa, andSouth America. High temperatures are required to extract lithium from its compounds and byelectrolysis of lithium chloride. It is also concentrated by solar evaporation of salt brine in lakes.Metallic lithium is produced on a commercial scale by electrolysis of molten lithium chloride (LiCl) that is heated as a mixture with potassium chloride (KCl). Both have a rather highmelting point, but when mixed, the temperature required to melt them (400°C) is severalhundred degrees lower than their individual melting points. This liquid mixture of LiCl andKCl becomes the electrolyte. The anode is graphite (carbon) and the cathode is steel. Themolten liquid positive lithium cations collect at the cathode while negative chlorine anionscollect at the anode, and the potassium chloride remains in the electrolyte. Each positive ion oflithium that collects at the cathode gains an electron, thus producing neutral atoms of moltenlithium metal, which is then further purified.

純化方法After washing with pet ether to remove storage oil, lithium is fused at 400o and then forced through a 10-micron stainless-steel filter with argon pressure. It is again melted in a dry-box, skimmed, and poured into an iron distillation pot. After heating under a vacuum to 500o, cooling and returning it to the dry-box for a further cleaning of its surface, the lithium is distilled at 600o using an all-iron distillation apparatus [Gunn & Green J Am Chem Soc 80 4782 1958].
