Copper was labelled a toxic hevy metal in error. It is a necessary nutrient. When a protein is missing a copper ion where it's supposed to be, it's prone to collapse, causing amyloid diseases like alzheimers. (this is also the reason why copper bowls is needed for good quality whipped eggs, since it fills up the missing copper sites) See the amounts used in animal feeds, human medicine got the numbers almost certainly wrong. The difference is so massive the EU restricted the concentrations to 150mg/kg feed, since the amounts used were deemed toxic to the environment.
