Individuals residing in U.S. households supplied with tap water containing >3 mg/L of copper exhibited no adverse health effects. [ 105 ] No effects of copper supplementation on serum liver enzymes, biomarkers of oxidative stress, and other biochemical endpoints have been observed in healthy young human volunteers given daily doses of 6 to 10 ...
Copper toxicity (or Copperiedus) is a type of metal poisoning caused by an excess of copper in the body. Copperiedus could occur from consuming excess copper salts, but most commonly it is the result of the genetic condition Wilson's disease and Menke's disease, which are associated with mismanaged transport and storage of copper ions.
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 ]
Copper alloy surfaces have intrinsic properties that destroy many microorganisms.In the interest of protecting public health, especially in healthcare environments with their susceptible patient populations, an abundance of peer-reviewed antimicrobial efficacy studies have been conducted in the past ten years regarding copper's efficacy to destroy E. coli O157:H7, methicillin-resistant ...
Appropriate intake levels of certain chemical elements have been demonstrated to be required to maintain optimal health. Diet can meet all the body's chemical element requirements, although supplements can be used when some recommendations are not adequately met by the diet.
] Excessive absorption of zinc can suppress copper and iron absorption. The free zinc ion in solution is highly toxic to bacteria, plants, invertebrates, and even vertebrate fish. [2] [3] [4] Zinc is an essential trace metal with very low toxicity in humans. [1] [5]
Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk.

The toxic effects of arsenic, mercury and lead were known to the ancients but methodical studies of the overall toxicity of heavy metals appear to date from only 1868. In that year, Wanklyn and Chapman speculated on the adverse effects of the heavy metals "arsenic, lead, copper, zinc, iron and manganese" in drinking water. They noted an ...
