Copper occurs naturally in elemental form and as a component of many minerals.
Because of its high electrical and thermal conductivity, it is widely used in the manufacture of electrical equipment. Copper can be absorbed by the oral, inhalation, and dermal routes of exposure. The chronic toxicity of copper has been characterized in patients with Wilson's disease, a genetic disorder causing copper accumulation in tissues. No suitable bioassays or epidemiological studies are available to assess the carcinogenicity of copper.
