Why is copper not a toxic metal to humans?
Copper is not very toxic in comparison to other metals and early humans used too little of it to begin concentrating it in soil, air, or water to the extent that it would affect human health or ecosystems. It appears that during the first few thousand years of its use, humans experiment with and learned techniques to utilize copper.

What happens if you have too much copper in your body?
You can also have too much copper if you have a condition that stops the body from getting rid of copper.

Extra copper in the liver overflows and builds up in the kidneys, brain, and eyes.
