Electrochemistry of High Concentration Copper Chloride ...

High concentrations of copper chloride solutions (in the molar range) are used in several industrial applications. In this work, we investigated the species distribution of copper chloride complexes and how to measure the copper concentration precisely at high concentrations using electrochemical methods, by including migrational effects. The latter, in fact, can be useful in determining the ...

Copper Toxicity - Copper Toxicity

Copper toxicity may sometimes be referred to as hypercupremia, though it is a misleading term since hypercupremia literally translates to mean 'high copper concentration in the blood' even though blood levels are almost entirely irrelevant in assessing copper toxicity.Symptoms of copper toxicity can very much exist even when blood levels are normal or low.

Lowering Swimming Pool Copper

It's important to keep your copper level as low as possible and as close to zero as you can. Stained hair, fingernails, and pool surfaces can result in water with copper levels too high. With routine testing, balanced pool water, and occasional copper adjustment, you should rarely have trouble with copper in your swimming pool. Sources:

Ceruloplasmin - Wikipedia

Ceruloplasmin (or caeruloplasmin) is a ferroxidase enzyme that in humans is encoded by the CP gene.. Ceruloplasmin is the major copper-carrying protein in the blood, and in addition plays a role in iron metabolism.It was first described in 1948. Another protein, hephaestin, is noted for its homology to ceruloplasmin, and also participates in iron and probably copper metabolism.
