^^ Dithane isn't ... persistent either, being rapidly broken down in the soil and metabolised in cells - unlike copper based fungicides.
It is extremely unlikely that a substance as simple and well-understood as copper can surprise us when it has been used against blight since just after the Potato Famine (1844).
No metal is 'safe' in your body at 'any' level.
Copper essentialityFor a detailed discussion about copper homeostasis, absorption, distribution, and excretion, see: [2]Copper is an essential trace element that is vital to the health of all living things (humans, plants, animals, and microorganisms). The human body normally contains copper at a level of about 1.4 to 2.1 mg for each kg of body weight.[42] Copper is distributed widely in the body and occurs in liver, muscle and bone. Copper is transported in the bloodstream on a plasma protein called ceruloplasmin. When copper is first absorbed in the gut it is transported to the liver bound to albumin. Copper metabolism and excretion is controlled delivery of copper to the liver by ceruloplasmin, where it is excreted in bile.

depends what levels you have. The roman empire declined partially through lead poisoning.Its the same for any chemical, or substance, its depends on the level . Have you ever heard of 'protein poisoning' , for example, caused by trying to live on an exclusive diet of rabbit meat ?? However, if you feel its safe to chew copper panel pins, carry on, dont let me stop you, im all for free will.
You didnt say it depends on what level you have. You saidQuoteNo metal is 'safe' in your body at 'any' level.Thats wrong and thats what I replied to.

'if the criteria is that all any level of the metal in your body from 0% to 100% is safe, then that statement is wrong'
