The suggested safe level of copper in drinking water for humans varies depending on the source, but tends to be pegged at 1.3 mg/L. [2] So low is the toxicity of copper that copper(II) sulfate is a routine reagent in undergraduate chemistry laboratories.
The long-term toxicity of copper has not been well studied in humans, but it is infrequent in normal populations that do not have a hereditary defect in copper homeostasis. [103] There is little evidence to indicate that chronic human exposure to copper results in systemic effects other than liver injury. [82]
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. [ 1 ]
Chronic copper toxicity does not normally occur in humans because of transport systems that regulate absorption and excretion. Autosomal recessive mutations in copper transport proteins can disable these systems, leading to Wilson's disease with copper accumulation and cirrhosis of the liver in persons who have inherited two defective genes. [203]
The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [2] Cleanup costs may exceed $1.2 billion. [3] A toxic heavy metal is a common but misleading term for a metal-like element noted for its potential toxicity. [4]
Copper: copper toxicity usually presents itself as a side effect of low levels of the protein ceruloplasmin, which normally is involved in copper storage. This is referred to as Wilson’s disease . Wilson's disease is an autosomal recessive genetic disorder whose mutation causes the ATPase that transports copper into bile and ultimately ...
A new federal report from a group within the Department of Health and Human Services found that one alcoholic drink per day could raise the risk of negative health effects like liver cirrhosis and ...
Copper deficiency, or hypocupremia, is defined as insufficient copper to meet the body's needs, or as a serum copper level below the normal range. [1] Symptoms may include fatigue , decreased red blood cells , early greying of the hair, and neurological problems presenting as numbness , tingling, muscle weakness, and ataxia . [ 2 ]
