History and Uses
Lead has been known since ancient times. The origin of the name comes from the Latin word plumbum meaning liquid silver. Lead is one of the first metals to have been used by humans, with uses dating back to 6500 BC. Trace amounts of other elements, including gold, are sometimes found with lead ore. The most common lead ore is galena, or lead sulfide. 

Lead is generally under the hood of an auto, buried in a television or otherwise remote from consumers. We safely use and recycle lead in dozens of important consumer, industrial and defense applications, including batteries for automobiles, industrial trucks and other equipment, X-ray and radiation shielding, waterproofing materials, noise and vibration barriers, optics, electronics and computers, sports equipment and many more. Lead has been used as a protective shield against radon exposure in homes and lead batteries will play an important role in the development and use of cars.
