• 5 Health Effects of Excess Copper | Copper in Drinking ...

    For systemic effects, doses of copper in water associated with health effects differ from toxic doses in environmental media because of differences in bioavailability among water, food, and other environmental media. Copper ions in water have the highest bioavailability. The bioavailability of copper in the diet is a function of its solubility and also the types of complexes in which it is ...
