Chronic toxicity by copper is rare. [1] 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. [3]
Normal absorption and distribution of copper. Cu = copper, CP = ceruloplasmin, green = ATP7B carrying copper. Copper is an essential trace element that is vital to the health of all living things (plants, animals and microorganisms). In humans, copper is essential to the proper functioning of organs and metabolic processes.
Cu with a half-life of 61.83 hours. [24] Seven metastable isomers have been characterized; 68m Cu is the longest-lived with a half-life of 3.8 minutes. Isotopes with a mass number above 64 decay by β −, whereas those with a mass number below 64 decay by β +. 64 Cu, which has a half-life of 12.7 hours, decays both ways. [25] 62 Cu and 64 Cu
EPA illustration of lead sources in residential buildings Infographic about lead in drinking water. The Lead and Copper Rule (LCR) is a United States federal regulation that limits the concentration of lead and copper allowed in public drinking water at the consumer's tap, as well as limiting the permissible amount of pipe corrosion occurring due to the water itself.

Coffee sure has made the rounds regarding its health status. Many years ago, it was thought to be a noxious habit. More recently, however, evidence is mounting toward its beneficial effects on health.
One, your coffee habits: If you’re accustomed to drinking coffee first thing in the morning, your body may have come to use the caffeine as a crutch and thrown off its natural wake-up mechanisms.

Copper (29 Cu) has two stable isotopes, 63 Cu and 65 Cu, along with 28 radioisotopes. The most stable radioisotope is 67 Cu with a half-life of 61.83 hours. Most of the others have half-lives under a minute. Unstable copper isotopes with atomic masses below 63 tend to undergo β + decay, while isotopes with atomic masses above 65 tend to ...
