鉛

鉛は密度が高く、延性に富み、青灰色をした金属で、室温では固体であり、揮発性が低い。融点は327.5 ℃、沸点は1749 ℃である。周期表上は準金属（ポストトランジション金属）および元素としての重金属に分類される。鉛は主に鉛蓄電池、放射線遮蔽材、およびベアリングやはんだ用鉛合金の原料として使用される。また、特定の顔料（例：鉛クロメート）、ポリ塩化ビニル（PVC）用安定剤、光学ガラスおよび放射線防護ガラスを含む特殊ガラスの製造にも用いられる。その用途は、エネルギー貯蔵、建設資材、自動車部品、産業用遮蔽材に集中している。

Lead is one of the oldest metals known to civilization. The uses of some of its alloys and salts have been documented early in history. The element derived its symbol Pb from the Latin word plumbium. The metal is rarely found in nature in its native form; however, it is found in several minerals, such as galena (PbS), anglesite (PbSO4), minium (Pb3O4) and cerussite (PbCO3). Its concentration in the earth’s crust is 12.5 mg/kg and in sea water 0.03mg/L.Lead has numerous applications as metal, alloys and compounds. The major applications of the metal and its alloys such as solder are as materials of construction for pipe lines, plumbing fixtures, wires, ammunition, containers for corrosive acids and shield against short-wavelength radiation. Another major application is in storage batteries in which both the metal and its dioxide are used. Several lead compounds, such as lead chromate (chrome yellow), lead sulfate (white lead), lead tetroxide (red lead), and the basic carbonate are used in paints.
