概述

Copper is a metal that occurs naturally throughout the environment, in rocks, soil, water, and air. Copper is an essential element in plants and animals (including humans), which means it is necessary for us to live. Therefore, plants and animals must absorb some copper from eating, drinking, and breathing. Copper is used to make many different kinds of products like wire, plumbing pipes, and sheet metal. U.S. pennies made before 1982 are made of copper, while those made after 1982 are only coated with copper. Copper is also combined with other metals to make brass and bronze pipes and faucets. Copper compounds are commonly used in agriculture to treat plant diseases like mildew, for water treatment and, as preservatives for wood, leather, and fabrics.

Copper is a metal that occurs naturally throughout the environment, in rocks, soil, water, and air. Copper is an essential element in plants and animals (including humans), which means it is necessary for us to live. Therefore, plants and animals must absorb some copper from eating, drinking, and breathing. Copper is used to make many different kinds of products like wire, plumbing pipes, and sheet metal.

Copper compounds are commonly used in agriculture to treat plant diseases like mildew, for water treatment and, as preservatives for wood, leather, and fabrics.

Copper fumes can cause metal fume fever. Hemolytic anemia has been reported after toxic ingestion. [Rosenstock, p. 983] In acidic conditions, metallic copper releases toxic copper ions. Acute copper poisoning can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria. [Goldfrank, p. 1256-60] There are two TLVs, one for Copper, fume, as Cu and one for Copper, dusts and mists, as Cu. There is also a MAK for Copper and its inorganic compounds. [ACGIH] Copper in drinking water at >4 mg/L can cause gastrointestinal distress. At higher doses, ingested copper salts can cause hemolysis and injury to the liver and kidneys. [Nordberg, p. 765] In high-dose animal studies, excess copper is embryotoxic; Women with Wilson's disease (excess copper) may have infertility and increased spontaneous abortions; [REFPROTOX] See Copper sulfate.

Health Effects · 1 条

Copper toxicity, also called copperiedus, refers to the consequences of an excess of copper in the body. Copperiedus can occur from eating acid foods cooked in uncoated copper cookware, or from exposure to excess copper in drinking water or other environmental sources. Very-high doses of copper can damage liver and kidneys, and can even cause death. Copper may induce allergic responses in sensitive individuals. (L278, L279)

Hepatotoxicity · 1 条

Acute hepatotoxicity of copper is usually the result of ingestion of toxic amounts (1 to 10 g), often as a suicide attempt. In children, accidental poisoning can occur, particularly with ingestion of coins. Initial symptoms may be metallic taste and gastrointestinal distress due to gastric or small bowel erosions. Acute overdoses of copper can lead to early appearance of cardiovascular collapse, coma and death within hours. Liver injury tends to arise after 24 to 72 hours and is characterized by marked elevations in serum aminotransferase levels, minimal increases in alkaline phosphatase, early appearance of hepatic failure, and elevation in prothrombin time and ensuing jaundice. Shock and renal failure may also be present as well as rhabdomyolysis and severe hemolytic anemia. The overall clinical pattern of the liver injury is that of acute hepatic necrosis, and the hepatic manifestations resemble the acute toxicity of iron and zinc, and can be reproduced in animals. Shock and rhabdomyolysis may contribute to the serum enzyme elevations while hemolytic anemia may account for some of the increase in total bilirubin levels. Therapy of copper overdose includes gastric lavage, fluid replacement, dimercaprol (BAL) and penicillamine, with blood transfusions for hemolytic anemia and dialysis for acute renal failure.

Environmental Fate · 1 条

Terrestrial Fate: The fate of copper with respect to its leachability in purely organic spruce forest soils was studied. Appreciable mobilization of copper occurred only with prolonged leaching at pH 2.8. Therefore, it does not appear likely that acidic rainfall will result in significant mobilization of copper from organic soils unless the pH of rainfall decreases to < 3. ... Estimated that approx 50% of copper in the top few centimeters of these soils was organically bound, approx 18% was in the hydroxy carbonate form, approx 7% was in the adsorbed state, approx 11% was bound by other anions and 6% was irreversibly adsorbed. Only 3% of the copper was extractable with water at pH 4.5; hence only 3% was mobile at this pH. ... In urbanized areas the effects of land clearing, profile disruption and increased acid rainfall may increase copper mobilization in these soils.

Protein BindingCopper is nearly entirely bound by ceruloplasmin (65-90%), plasma albumin (18%), and alpha 2-macroglobulin (12%).
PharmacodynamicsCopper is incorporated into many enzymes throughout the body as an essential part of their function. Copper ions are known to reduce fertility when released from copper-containing IUDs.
Mechanism of Action · 2 条

Copper is absorbed from the gut via high affinity copper uptake protein and likely through low affinity copper uptake protein and natural resistance-associated macrophage protein-2. It is believed that copper is reduced to the Cu1+ form prior to transport. Once inside the enterocyte, it is bound to copper transport protein ATOX1 which shuttles the ion to copper transporting ATPase-1 on the golgi membrane which take up copper into the golgi apparatus. Once copper has been secreted by enterocytes into the systemic circulation it remain largely bound by ceruloplasmin (65-90%), albumin (18%), and alpha 2-macroglobulin (12%). Copper is an essential element in the body and is incorporated into many oxidase enzymes as a cofactor. It is also a component of zinc/copper super oxide dismutase, giving it an anti-oxidant role. Copper defiency occurs in Occipital Horn Syndrome and Menke's disease both of which are associated with impaired development of connective tissue due to the lack of copper to act as a cofactor in protein-lysine-6-oxidase. Menke's disease is also associated with progressive neurological impairment leading to death in infancy. The precise mechanisms of the effects of copper deficiency are vague due to the wide range of enzymes which use the ion as a cofactor. Copper appears to reduce the viabilty and motility of spermatozoa. This reduces the likelihood of fertilization with a copper IUD, producing copper's contraceptive effect. The exact mechanism of copper's effect on sperm are unknown.

The reason for the less severe reaction when the foreign body is at a distance from the retina has been proposed to be ... that near the retina & its blood vessels there is greater oxygen tension than at a distance, which causes metallic copper to oxidize to toxic copper compounds more rapidly close to or in contact with the retina than at a distance. Furthermore, the abscess formation that is characteristic of copper undergoing oxidation close to the retina & choroiod can be attributed to attraction of polymorphonuclear leukocytes from these nearby vascular tissues, which become heavily infiltrated. Liquefaction & disorganization of the vitreous body has been explained on the basis of copper catalysis of oxidation of ascorbic acid, leading to depolymerization of the hyaluronic acid of the vitreous humor. Changes in protein & hexosamine content have also been related to decrease in viscosity of the vitreous humor. Increased content of amino acids in the vitreous humor has been consistent with proteolysis of the vitreous body, but decreased concentration in the aqueous humor has suggested suppression of secretion of amino acids by the ciliary body under the influence of copper.

Biological Half-LifeWhole body: 4 weeks; [TDR, p. 392]
Metabolism/Metabolites · 1 条

Copper is mainly absorbed through the gastrointestinal tract, but it can also be inhalated and absorbed dermally. It passes through the basolateral membrane, possibly via regulatory copper transporters, and is transported to the liver and kidney bound to serum albumin. The liver is the critical organ for copper homeostasis. In the liver and other tissues, copper is stored bound to metallothionein, amino acids, and in association with copper-dependent enzymes, then partitioned for excretion through the bile or incorporation into intra- and extracellular proteins. The transport of copper to the peripheral tissues is accomplished through the plasma attached to serum albumin, ceruloplasmin or low-molecular-weight complexes. Copper may induce the production of metallothionein and ceruloplasmin. The membrane-bound copper transporting adenosine triphosphatase (Cu-ATPase) transports copper ions into and out of cells. Physiologically normal levels of copper in the body are held constant by alterations in the rate and amount of copper absorption, compartmental distribution, and excretion. (L277, L279)
