Salts, Acidic

Amines, Phosphines, and Pyridines

Solutions of COPPER CHLORIDE are acidic (they contain moderate concentrations of hydrogen ions and have pH's of less than 7.0). They react as acids to neutralize bases. These neutralizations generate heat, but far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid.

CUPRIC CHLORIDE SOLUTION, [AMMONIATED] has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

The effects of superoxide dismutase, catalase, copper(II) (3,5-diisopropylsalicylate)2 and other copper compounds on radiation transformation in vitro using C3H 10T1/2 cells have been studied. When present only during irradiation, cupric chloride and cuprous chloride inhibited the initiation phase of radiation transformation.

The ameliorating effects of copper(+2) and sulfate(2-) ions on concurrent selenite toxicity were compared in two factorial experiments in weanling rats. 0, 500 and 1,000 mg copper (as cupric chloride)/kg diet were fed in conjuction with 0, 5, 10 and 20 mg selenium (as Na2Se)3)/kg diet. Cupric(+2) ion, but not sulfate(2-) ion, prevented mortality among selenite intoxicated rats. There were significant copper-selenium interaction effects on feed intake, daily gain, packed cell volume, serum copper and iron, sperm counts, and weights of liver, kidney and testis. Sulfate increased liver copper concentrations.

Oral LD50 values (at 24 and 168 hr) for 8 metal salts were detected in female mice pretreated orally with small doses (1/10 of the challenge doses) of the same metal ions or with deionized water at 24 hr prior to the challenge doses. Pretreatment with copper(2+), had little effect on the lethality of the same ion. Pretreatment with copper(2+), mercury(2+), or zinc(2+) protected mice against the toxic action of cadmium(2+).

Salts of metals which are carcinogenic, noncarcinogenic, or of unknown carcinogenicity were assayed for their abilities to modulate ultraviolet induced mutagenesis in Escherichia coli WP2. Copper chloride acted as comutagen in E coli WP2, which has wild type DNA repair capability, but was much less comutagenic in the repair deficient strain WP2S (uvra). The survival of irradiated or unirradiated cells was not affected by the compound. The comutagenic effects might occur either via metal induced decreases in the fidelity of repair replication or via metal induced depurination.

People must absorb small amounts of copper every day because copper is essential for good health, however, high levels of copper can be harmful. Very-high doses of copper can cause damage to your liver and kidneys, and can even cause death. Copper may induce allergic responses in sensitive individuals. (L278, L279)

For healthy, non-occupationally-exposed humans the major route of exposure to copper is oral. The mean daily dietary intake of copper in adults ranges between 0.9 and 2.2 mg. ... In some cases, drinking water may make a substantial additional contribution to the total daily intake of copper, particularly in households where corrosive waters have stood in copper pipes. ... All other intakes of copper (inhalation and dermal) are insignificant in comparison to the oral route. Inhalation adds 0.3-2.0 ug/day from dusts and smoke. Women using copper IUDs are exposed to only 80ug or less of copper per day from this source. The homeostasis of copper involves the dual essentiality and toxicity of the element. Its essentiality arises from its specific incorporation into a large number of proteins for catalytic and structural purposes. The cellular pathways of uptake, incorporation into protein and export of copper are conserved in mammals and modulated by the metal itself. Copper is mainly absorbed through the gastrointestinal tract. From 20 to 60% of the dietary copper is absorbed, with the rest being excreted through the feces. Once the metal passes through the basolateral membrane it is transported to the liver bound to serum albumin. The liver is the critical organ for copper homeostatis. The copper is partitioned for excretion through the bile or incorporation into intra- and extracellular proteins. The primary route of excretion is through the bile. The transport of copper to the peripheral tissues is accomplished through the plasma attached to serum albumin, ceruloplasmin or low-molecular weight complexes. ... The biochemical toxicity of copper, when it exceeds homeostatic control, is derived from its effects on the structure and function of biomolecules, such as DNA, membranes and proteins directly or through oxygen-radical mechanisms. The toxicity of a single oral dose of copper varies widely between species. ... The major soluble salts (copper(II) sulfate, copper(II) chloride) are generally more toxic than the less soluble salts (copper(II) hydroxide, copper (II) oxide). Death is preceded by gastric hemorrhage, tachycardia, hypotension, hemolytic crisis, convulsions and paralysis. ... Long-term exposure in rats and mice showed no overt signs of toxicity other than a dose-related reduction in growth after ingestion ... The effects included inflammation of the liver and degeneration of kidney tubule epithelium. ... Some testicular degeneration and reduced neonatal body and organ weights were seen in rats ... and fetotoxic effects and malformations were seen at high dose levels. ... Neurochemical changes have been reported after oral administration ... A limited number of immunotoxicity studies showed humoral and cell-mediated immune function impairment in mice after oral intakes in drinking-water ... Copper is an essential element and adverse health effects /in humans/ are related to deficiency as well as excess. Copper deficiency is associated with anemia, neutropenia and bone abnormalities but clinically evident deficiency is relatively infrequent in humans. .. Except for occasional acute incidents of copper poisoning, few effects are noted in normal /human/ populations. Effects of single exposure following suicidal or accidental oral exposure have been reported as metallic taste, epigastric pain, headache, nausea, dizziness, vomiting and diarrhea, tachycardia, respiratory difficulty, hemolytic anemia, hematuria, massive gastrointestinal bleeding, liver and kidney failure, and death. Gastrointestinal effects have also resulted from single and repeated ingestion of drinking-water containing high copper concentrations, and liver failure has been reported following chronic ingestion of copper. Dermal exposure has not been associated with systemic toxicity but copper may induce allergic responses in sensitive individuals. Metal fume fever from inhalation of high concentrations in the air in occupational settings have been reported ... A number of groups are described where apparent disorders in copper homeostasis result in greater sensitivity to copper deficit or excess than the general population. Some disorders have a well-defined genetic basis. These include Menkes disease, a generally fatal manifestation of copper deficiency; Wilson disease (hepatolenticular degeneration), a condition leading to progressive accumulation of copper; and hereditary aceruloplasminemia, with clinical symptoms of copper overload. Indian childhood cirrhosis and idiopathic copper toxicosis are conditions related to excess copper which may be associated with genetically based copper sensitivity ... These are fatal conditions in early childhood where copper accumulates in the liver. ... Other groups potentially sensitive to copper excess are hemodialysis patients and subjects with chronic liver disease. Groups at risk of copper deficiency include infants (particularly low birth weight/preterm babies, children recovering from malnutrition, and babies fed exclusively with cow's milk), people with maladsorption syndrome (e.g., celiac disease, sprue, cystic fibrosis), and patients on total parenteral nutrition. Copper deficiency has been implicated in the pathogenesis of cardiovascular disease. The adverse effects of copper must be balanced against its essentiality. Copper is an essential element for all biota ... At least 12 major proteins require copper as an integral part of their structure. It is essential for the utilization of iron in the formation of hemoglobin, and most crustaceans and molluscs possess the copper-containing hemocyanin as their main oxygen-carrying blood protein. ... A critical factor in assessing the hazard of copper is its bioavailablity. Adsorption of copper to particles and complexation by organic matter can greatly limit the degree to which copper will be accumulated ... At many sites, physiochemical factors limiting bioavailability will warrant higher copper limits. ...

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)

The freshwater teleost Tilapia mossambica was subjected to lethal (6.0 mg/l= LC50/48 hr) and sublethal (1.5 mg/l) copper treatment for 1, 7, and 14 days. The whole animal oxygen consumption and the activity levels of succinate dehydrogenase and lactate dehydrogenase in liver and muscle were studied. The decrease in oxygen consumption and succinate dehydrogenase activity and significant increase in lactate dehydrogenase activity suggest that the stressed fish is meeting its energy requirement through anaerobic oxidation and these enzymes can be used as indicators in monitoring metal induced toxicity in fish.

The role of lysosomes in the pathogenesis of copper induced hepatotoxicity was studied in mice. Two strains of female C57B1-mice (conventional and beige) were injected intraperitoneally with 0 or 8 milligrams per kilogram aqueous copper (II) chloride daily for up to 4 weeks. Macroscopically, the livers of mice treated for 1 week were similar to those of the controls. After 2 weeks, livers of treated animals were diffusely tan to red and the edges of the individual lobes were blunted. At 4 weeks, the livers were gray to tan, and their lobes were marked rounded. Hepatic lesions consisting of karyomegaly, accumulation of lipofuscin within hepatocytes, and Kupffer cells, acute necrosis of random hepatocytes, and aggregation of leukocytes within the sinusoids developed in both strains; however, they developed more quickly and were more severe in beige mice. In both strains, the onset of the hepatic lesions closely paralleled the appearance and distribution of copper within the leukocytes. Beige mice are more susceptible to copper mediated hepatotoxicity, suggesting that normal lysosomes have protective effects for hepatocytes by sequestering copper from other cytoplasmic components.

Copper is an essential nutrient which serves as a co factor for serum ceruloplasmin, an oxidase necessary for proper formation of the iron carrier protein, transferrin. Copper also helps maintain normal rates of red and white blood cell formation. Providing copper during Total Parenteral Nutrition helps prevent development of the following deficiency symptoms: Leukopenia, neutropenia, anemia, depressed ceruloplasmin levels, impaired transferrin formation, secondary iron deficiency and osteoporosis.

The in vitro interaction of organic copper compounds with rat liver glutathione S-transferases was studied with reduced glutathione and 1-chloro-2,4-dinitrobenzene as substrates. Both organic and inorganic copper are spontaneously conjugated with glutathione, but interact with glutathione S-transferase by direct binding to these proteins.

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 homoeostasis. 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)

Mean copper absorption of 57 percent (range 40 to 70 per cent) following oral administration of 0.4 - 4.5 mg copper (as copper acetate) to four volunteers. An early human study suggested a maximum blood copper concentration was reached some two hours after oral copper chloride administration (1.5 - 12 mg copper)

Renal

Copper is distributed to all tissues with the highest concentrations in liver, heart, brain, kidneys and muscle. Intracellular copper is predominantly metallothionein-bound. Reported copper in the lungs, liver, kidney, blood, bile and stomach (33.7, 35.1, 41.4, 13.8, 2.8, and 2988 µg/g wet weight respectively)

ICR male mice aged 5 weeks were injected subcutaneously with cadmium chloride, lead acetate, silver nitrate, cupric chloride, a combination of cadmium and silver compounds, or a combination of copper and silver compounds. These injections were carried out 3 times. Twenty four hours after the last injection, they were sacrificed. Cadmium injection significantly stimulated serum ceruloplasmin activity and copper concentration, accompanied by an increase in hepatic copper. Lead injection also slightly increased the serum ceruloplasmin level. In contrast, silver injection markedly decreased both serum ceruloplasmin activity and copper concentration in the serum. Hepatic copper increased slightly after silver injection. The copper injection stimulated copper binding to metallothionein and bile excretion of copper, but not serum ceruloplasmin release. With a copper and silver combination, the effect of silver on serum ceruloplasmin was lost, with a concomitant disappearance of silver from the serum ceruloplasmin fraction in the serum. In the mouse, cadmium and silver, copper antagonistic metals, influence different sites of serum ceruloplasmin metabolism. Excess hepatic copper is partly eliminated by excretion of bile and is partly detoxified by metallothionein induction.
