Copper was a vital constituent of Romulan and Vulcan blood hemoglobin, causing their blood to be colored green. (TOS: "The Man Trap") It was also a component in the blood of the Acamarians, along with iron, making Acamarian blood readily identifiable. (TNG: "The Vengeance Factor") It could also be used to produce copper tubing. (Star Trek: First Contact)
