Metals, Less Reactive

COPPER combines violently with chlorine trifluoride in the presence of carbon [Mellor 2, Supp. 1, 1956]. Is oxidized by sodium peroxide with incandescence [Mellor 2:490-93, 1946-1947]. Forms an unstable acetylide when acetylene is passed over samples that have been heated enough to form an oxide coating. Reacts more rapidly in powdered or granular form. Subject to explosive reaction then mixed in finely divided form with finely divided bromates chlorates and iodates of barium, calcium, magnesium, potassium, sodium, or zinc; these reactions are initiated by heat, percussion, and occasionally light friction [Mellor 2:310, 1946-1947]. A solution of sodium azide in copper pipe with lead joints formed copper azide and lead azide, both of these compounds can detonate [Klotz, 1973].

... Substances for which a Federal Register notice has been published that included consideration of the serious health effects, including cancer, from ambient air exposure to the substance. Copper (52 FR 5496; Feb 23, 1987) is included on this list.

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.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 5000 lb or 2270 kg. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

Copper toxicity is belevied to be due to fenton-type redox reactions occuring with high copper concentrations which produce damaging reactive oxygen species.

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.

Persons at special risk include those with impaired pulmonary function, especially those with obstructive airway diseases, since the breathing of copper fume might cause exacerbation of symptoms due to its irritant properties. /Copper fume/

The marked concentrations of copper in shales & sandstones suggest that copper in the lithosphere exists largely as adsorbed ions, fine grained particles or as one of many discrete sedimentary copper minerals. Generally, these minerals occur only as sparse tiny grains that are widely disseminated throughout the sedimentary rocks.

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.

A study was conducted on the distribution of managanese, iron, copper, lead, and zinc in the water and sediment of Kelang esturary in 1981. The mean total levels of manganese, iron, copper, lead, and zinc in the estuarine water were 27.1 ug/l, 106.5 g/l, 10.0 ug/l, 4.1 ug/l and 17.9 ug/l respectively. The results indicate that Kelang estuary is polluted with lead, manganese, and iron. However, levels of these heavy metals may still be considered safe for aquaculture, if the farm is located at least 10 km away from the river mouth.

Copper is an essential trace element that is included in some over-the-counter multivitamin and mineral supplements, even though copper deficiency is quite rare and supplementation is rarely needed. The amounts of copper found in typical supplements has not been associated with serum enzyme elevations or with clinically apparent liver injury. However, accidental or intentional copper overdose can cause an acute liver injury and chronic ingestion of excessive amounts of copper can result in copper overload and chronic liver injury.

Trace Elements and Metals

Copper has a contraceptive effect when present in the uterus. It is added to some intrauterine contraceptive devices permitting reduction in their size with concomitant reduction in the associated side effects such as pain and bleeding.

Copper 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.

The rhythm in the copper excretion depends on the creatinine rhythm, ie the rhythm of glomerular filtration.|For more Absorption, Distribution and Excretion (Complete) data for COPPER, ELEMENTAL (6 total), please visit the HSDB record page.

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 likelyhood 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.
