Description and Uses
Copper has long been used by humans for a variety of reasons. The name copper derives from the Latin for the metal, cuprum, which is named for the Roman source, the island of Cyprus. Copper has been used in a variety of alloys; of particular importance among copper alloys is bronze, which comprised most of the tools and weapons of the age that bears its name. Brass, a copper–zinc alloy, is also highly used, for example, in brass musical instruments. Copper has also long been used as a building material, and owing to the metal’s malleability, as well as high thermal and electric conductivity, continues to find new uses. Copper and its compounds are naturally present in the earth’s crust. Natural discharges to air and water may be significant. Therefore, it is important to consider the background levels that are commonly found and distinguish these from high levels that may be found as a result of anthropogenic activity. Copper is emitted into the air naturally from windblown dust, volcanoes, and anthropogenic sources, the largest of which are being primary copper smelters and ore processing facilities. It is associated with particulate matter. The mean concentration of copper in the atmosphere is 5–200 ng m-3.
Copper, being easy to mine and refine, has become a very versatile metal over the course ofcivilization. Early in human history, it was discovered that soft copper could be made harderand stronger when alloyed with other metals. Copper was and still is important to technologyand the development of civilizations. Over the past several thousand years, brass has foundmultiple uses, such as in coins, cooking utensils, and many types of instruments and hardwarethat are resistant to corrosion. Even today, brass is used to make musical instruments andbathroom, kitchen, and marine hardware. The U.S. one-cent penny was originally made ofcopper, but today the penny is made of zinc with a coating of copper. Copper is also an alloymetal used as a substitute for some of the silver in several other U.S. coins.Some common uses are in electrical wiring and components of electronic equipment,roofing, and pipes and plumbing and in the manufacturing of alloys such as brass, bronze,Monel metal, electroplating, jewelry, cooking utensils, insecticides, marine paints, cosmetics,and wood preservatives.Copper is second only to silver as an excellent conductor of electricity. This factor and itsavailability made it essential for the expansion of modern technologies. It was, and still is, adesired metal for wires to carry electricity, but the rapid expansion of modern communicationswould require more copper than could be made economically available. The solution has beento use optical fiberglass transmission cables as a substitute for copper wire. In addition, andeven more important, is the recent explosive growth of wireless transmission as a substitute forcopper wire in the communication industries.
