Basic salts occur in nature as the minerals: cornetite, dihydrite, libethenite, phosphorochalcite, pseudolibethenite, pseudomalachite, tagilite.

Breathing high levels of copper can cause irritation of the nose and throat. Ingesting high levels of copper can cause nausea, vomiting, diarrhea, headache, dizziness, and respiratory difficulty. (L278, L279)

EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

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)

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

Oral (L277); inhalation (L277); dermal (L277)

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...

Acute Oral: 0.01 mg/kg/day (L134) Intermediate Oral: 0.01 mg/kg/day (L134)

The available human data indicate that gastrointestinal distress occurred following ingestion of solutions that contained 5-7 mg of copper and other unknown chemicals as a single dose. These data were used to derive a 1 day health advisory of 1.3 mg/l which, when spread over a day, should provide protection from these acute effects. Since the effects appear to be local irritation, this health advisory is recommended for both the child and the adult. There are no data indicating that human exposure to copper results in chronic toxic effects. Furthermore, there is a nutritional requirement for copper and acute effects appear to be the effects of concern. Therefore, the one day health advisory, 1.3 mg/l, will also be used as the adjustable acceptable daily intake. /Copper/

No indication of carcinogenicity to humans (not listed by IARC).

Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Start an IV with lactated Ringer's /SRP: "To keep open", minimal flow rate/. Watch for signs of fluid overload. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Use proparacaine, hydrochloride to assist eye irrigation ... . /Copper and related compounds/
