Description
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.
Reddish lustrous malleable odorless metallic solid.
Copper atom is a copper group element atom and a metal allergen. It has a role as a micronutrient and an Escherichia coli metabolite.

6.2 LiverTox Summary

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.

Comments
The level of copper in food meets the nutritional requirements (2-3 mg/day for adults; 0.5-0.7 mg/day for infants). Copper is not carcinogenic in either humans or animals, and copper salts are not embryotoxic in rodents. Highly-exposed populations do not appear to be adversely affected, nor does copper appear to be a cumulative toxic hazard for man, except for individuals with Wilson's disease. On this basis, the previous tentative evaluation of a maximum daily load of 0.5 mg/kg bw was reaffirmed as a provisional value for a maximum tolerable intake of 0.5 mg/kg bw per day from all sources.

Mineral Description
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores. Copper is one of the oldest metals ever used and has been one of the important materials in the development of civilization. Because of its properties, singularly or in combination, of high ductility, malleability, and thermal and electrical conductivity, and its resistance to corrosion, copper has become a major industrial metal, ranking third after iron and aluminum in terms of quantities consumed. Electrical uses of copper, including power transmission and generation, building wiring, telecommunication, and electrical and electronic products, account for about three quarters of total copper use. Building construction is the single largest market, followed by electronics and electronic products, transportation, industrial machinery, and consumer and general products. Copper byproducts from manufacturing and obsolete copper products are readily recycled and contribute significantly to copper supply.

Absorption
Copper absorption varies inversely with intake. Absorption range is 12-65%.
Route of Elimination
Copper appears to be eliminated primarily through bile.
Small fragments of copper ... in the anterior vitreous just behind the lens in a number of cases have been observed for years, gradually dissolving & disseminating copper to lens, cornea & iris, where copper has a predilection for the basement membranes.

Circadian rhythms in the urinary excretion of eleven heavy metals and organic substances were examined under free, water restrictive and water loading conditions for 6 days (2 days for each of the three conditions) in twenty metal workers exposed to lead, zinc, and copper. Circadian rhythms were found for all heavy metals and organic substances as well as for urinary flow rate, creatinine and total urinary solutes. The rhythm in the copper excretion depends on the creatinine rhythm, ie the rhythm of glomerular filtration.

10.6 Metabolism / Metabolites

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)

10.8 Mechanism of Action

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.

CRUSH, GRIND, AND CONCENTRATE COPPER ORES BY FLOTATION (SULFIDE ORES) OR LEACHING WITH ACID (OXIDE ORES); SMELT CONCENTRATES TO YIELD A BLISTER COPPER WHICH IS REFINED ELECTROLYTICALLY OR FIRE REFINED
SRI
About 80% of the primary copper in the world comes from low-grade or poor sulfide ores, which are usually treated by pyrometallurgical methods, generally in the following sequence: (1) Beneficiation by froth flotation of ore to copper concentrate; (2) Optional partial roasting to obtain oxidized material or calcines; (3) two-stage pyrometallurgical extraction, (a) smelting concentrates to matte, (b) converting matte by oxidation to crude (converter or blister) copper; (4) Refining the crude copper, usually in two steps, (a) pyrometallurgically to fire-refined copper, (b) electrolytically to high-purity electrolytic copper.

12 Identification

12.1 Analytic Laboratory Methods

EPA Method 7210: Copper (Atomic Absorption, Direct Aspiration) Method 7210 is applicable for the determination of metals in solution by atomic absorption spectrometry. Preliminary treatment of wastewater, ground water, EP extracts, and industrial waste is always necessary because of the complexity and variability of sample matrix. After aspiration and atomization of the sample in a flame, a light beam from a hollow cathode lamp or an electrodeless discharge lamp is directed through the flame into a monochromator and onto a detector that measures the amount of light absorbed. ... The light energy absorbed by the flame is a measure of the concentration of that metal in the sample. The performance characteristics for an aqueous sample free of interferences are: a sensitivity of 0.1 mg/l, a detection limit of 0.02 mg/l, and an optimum concentration range 0.2-5 mg/l with wavelength of 324.7 nm. /Total copper/

Combustible. Finely dispersed particles form explosive mixtures in air.

13.1.5 Hazards Summary

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 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.

13.4 Fire Fighting

Excerpt from ERG Guide 170 [Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:

DO NOT USE WATER, FOAM OR CO2. Dousing metallic fires with water will generate hydrogen gas, an extremely dangerous explosion hazard, particularly if fire is in a confined environment (i.e., building, cargo hold, etc.). Use DRY sand, graphite powder, dry sodium chloride-based extinguishers, or class D extinguishers. Confining and smothering metal fires is preferable rather than applying water. If it can be done safely, move undamaged containers away from the area around the fire.

FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: If impossible to extinguish, protect surroundings and allow fire to burn itself out. (ERG, 2024)

Use special powder, dry sand. NO other agents. Water may be ineffective.

13.5 Accidental Release Measures

13.5.1 Isolation and Evacuation

Excerpt from ERG Guide 170 [Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

LARGE SPILL: Consider initial downwind evacuation for at least 50 meters (160 feet).

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

13.5.2 Spillage Disposal

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations.

13.5.3 Cleanup Methods

1. VENTILATE AREA OF RELEASE. 2. COLLECT SPILLED MATERIAL IN THE MOST CONVENIENT AND SAFE MANNER FOR RECLAMATION, OR FOR DISPOSAL IN A SECURE SANITARY LANDFILL. LIQ CONTAINING COPPER SHOULD BE ABSORBED IN VERMICULITE, DRY SAND, EARTH, OR A SIMILAR MATERIAL. /COPPER DUSTS & MISTS/

13.5.4 Disposal Methods

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Alternative treatment processes for metal bearing hazardous waste streams are reviewed. Precipitation is the preferred treatment process for removing toxic heavy metals from electroplating waters. Precipitation processes include hydroxide, lime and/or sulfide treatment. Chemical reduction is used to treat complex metals such as nickel, copper, hexavalent chromium waste, soluble lead, silver, metal containing cyanide, and mercury. Adsorption has shown potential for treating and polishing aqueous metal bearing wastes. Activated carbon, activated alumina, and iron filings are all applicable adsorbents. Alkaline chlorination and incineration are effective cyanide destruction treatments. Evaporation, ion exchange, reverse osmosis, electrodialysis, and electrolytic recovery are waste reduction and recovery techniques applicable to metal bearing hazardous streams.

The prevention of metal fume fever is a matter of keeping exposure below the level of concn currently accepted as satisfactory for working with copper in industry. The employment of local exhaust ventilation is a necessary measure to collect fumes at their source.
International Labour Office. Encyclopaedia of Occupational Health and Safety. 4th edition, Volumes 1-4 1998. Geneva, Switzerland: International Labour Office, 1998., p. 63.15
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
The major hazards are exposure to ore dusts during ore processing & smelting, metal fumes ... during smelting, sulfur dioxide & carbon monoxide during most smelting operations, ...& sulfuric acid & electrical hazards during electrolytic processes. Precautions include: local exhaust ventilation (LEV) for dusts during transfer operations; local exhaust & dilution ventilation for sulfur dioxide & carbon monoxide; ... protective clothing and shields... . Respiratory protection is commonly worn to protect against dusts, fumes & sulfur dioxide.
International Labour Office. Encyclopaedia of Occupational Health and Safety. 4th edition, Volumes 1-4 1998. Geneva, Switzerland: International Labour Office, 1998., p. 82.5
Employees should wash promptly when skin is contaminated. Work clothing should be changed daily if clothing is contaminated. Remove nonimpervious clothing promptly if contaminated. /Copper and compounds/

13.8 Stability and Reactivity

13.8.1 Air and Water Reactions

Solid pieces are very slowly oxidized by air to give a green basic carbonate. Solid pieces become covered by a black oxide when heated in air. Insoluble in water.

13.8.2 Reactive Group

Metals, Less Reactive

13.8.3 Reactivity Profile

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].

14 Toxicity

14.1 Toxicological Information

14.1.1 Toxicity Summary

Excess copper is sequestered within hepatocyte lysosomes, where it is complexed with metallothionein. Copper hepatotoxicity is believed to occur when the lysosomes become saturated and copper accumulates in the nucleus, causing nuclear damage. This damage is possibly a result of oxidative damage, including lipid peroxidation. Copper inhibits the sulfhydryl group enzymes such as glucose-6-phosphate 1-dehydrogenase, glutathione reductase, and paraoxonases, which protect the cell from free oxygen radicals. It also influences gene expression and is a co-factor for oxidative enzymes such as cytochrome C oxidase and lysyl oxidase. In addition, the oxidative stress induced by copper is thought to activate acid sphingomyelinase, which lead to the production of ceramide, an apoptotic signal, as well as cause hemolytic anemia. Copper-induced emesis results from stimulation of the vagus nerve. (L277, T49, A174, L280)

14.1.5 Hepatotoxicity

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.

Chronic liver injury from copper occurs with Wilson disease, but has also been described after chronic excessive ingestion of copper and perhaps as a result of chronic environmental exposure, such as from copper tubing used in hemodialysis.

Likelihood score: A[HD] (well known cause of acute and chronic liver injury but only when taken in high doses).

14.1.9 Health Effects

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)

Acute symptoms of copper poisoning by ingestion include vomiting, hematemesis (vomiting of blood), hypotension (low blood pressure), melena (black "tarry" feces), coma, jaundice (yellowish pigmentation of the skin), and gastrointestinal distress. Individuals with glucose-6-phosphate deficiency may be at increased risk of hematologic effects of copper. Hemolytic anemia resulting from the treatment of burns with copper compounds is infrequent. Chronic (long-term) effects of copper exposure can damage the liver and kidneys.

14.1.12 Target Organs

Gastrointestinal (Digestive), Hepatic (Liver)
Eyes, skin, respiratory system, liver, kidneys (increased risk with Wilson's disease)

14.1.13 Adverse Effects

Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.

Nephrotoxin - The chemical is potentially toxic to the kidneys in the occupational setting.

Methemoglobinemia - The presence of increased methemoglobin in the blood; the compound is classified as secondary toxic effect

Hemolytic anemia - Decreased hemoglobin or number of red blood cells.

Highly localized deposits of hepatic and renal copper have been observed in monkeys with copper IUDs and in control monkeys. Both copper and inert material IUDs have been observed to incr plasma copper levels. This may be explained by the observation that stress or inflammation alone can result in incr serum copper levels.
USEPA; Drinking Water Criteria Document for Copper (Final Draft) p.III-5 (1985) EPA-600/X-84-190-1
In order to establish a possible relationship between hemolytic and peroxidant activities of copper ions, lipid peroxidation was studied in plasma and whole blood incubated for 24 hr with different concentrations of copper. The copper induced lipoperoxidation was clearly demonstrated in plasma incubated with high concentrations of copper (12.10X-4 and 20.10X-4 M). With a copper concentration similar to that found in acute copper intoxication (4.10X-4 M) no lipoperoxidation was observed and yet hemolysis occurred, reduced glutathione decreased dramatically and methemoglobin increased. Despite its prooxidant activity and its capacity to produce lipoperoxidation, it has not been proven that copper ions at pathophysiological concentrations induce hemolysis by an oxidative mechanism.

The concentration of total plasma bile acids was measured in normal sheep and in sheep in which liver damage was induced by chronic copper poisoning, ligated bile ducts, or induced ketosis. All three treatments produced a rise in total bile acid concentration in plasma which was proportional to the degree of hepatic damage seen histologically and which tended to parallel changes in activity of iditol, and glutamate dehydrogenase and aspartate amino transferase in plasma. Plasma bile acid concentration was a more sensitive method of detecting these types of liver damage than was the measurement of total plasma bilirubin concentration, and could be used to assess alterations in liver function in sheep.

Symptoms of acute copper toxicity are sporadic fever, tachycardia, hypotension, hemolytic anemia with intravascular hemolysis, oliguria, uremia, coma, cardiovasuclar collapse, & death. The prompt emetic effect of copper limits its oral toxicity ... /because it/ irritates the nerve endings in the stomach & initiates the vomiting reflex in higher animals. Inhalation of dusts & fumes ... cause congestion of nasal mucous membranes, ulceration & perforation of the nasal septum, & pharyngeal congestion. ... Highly water soluble copper salts are more toxic than sparingly soluble salts; anions such as arsenite & chromate enhance apparent copper toxicity. /Soluble copper salts/

14.1.21 Populations at Special Risk

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/

Copper is present in concn averaging about 4 ppm in limestones, 55 ppm in igneous rocks, 50 ppm in sandstones, and 45 ppm in shales. 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.

14.2.7 Environmental Fate

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.

14.2.8 Environmental Water Concentrations

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.
Law AT, Singh A; Pertanika 9 (2): 209-18 (1986)

14.2.9 Plant Concentrations

The contents of copper, molybdenum, sulphur, zinc, selenium, iron, manganese, and the copper/molybdenum ratio were determined in different native plant species from a mountain area of central southern Norway. The overall mean values and ranges (mg/kg DM) were copper: 6.0, 0.9-27.2; molybdenum: 0.25, 0.01-3.57; zinc: 77, 8-320; selenium: 0.05, less than 0.01-0.32; iron: 208, 15-2245; manganese: 338, 31-3784; sulfur: (g/100 g DM) 0.20, 0.03-0.56; copper/molybdenum: 79, 1-7955. Levels of the individual elements showed considerable variability, both between and within plant groups. Mineral contents were compared with the established requirements for sheep and cattle, the following conclusion being drawn. The levels of zinc, sulphur, iron, and manganese were found to be adequate for ruminants.
