The quantity in an individual device is likely to be so tiny (milligrams) that it&#x27;s not a risk. It&#x27;s also likely to have been melted down and put through the global recycling chain which would have substantially diluted it. But it was a risk to people handling the original material in bulk. An unknown number of workers in the global copper supply and recycling chain were likely exposed to above-limit doses.<p>A lot of materials safety concerns are more for protection of workers than end users. Lead removal from electronics is an example. There&#x27;s not really any risk to owning electronics with lead in them unless you are incinerating them or enjoy licking circuit boards, but it is a serious occupational risk to factory workers and also a disposal problem.
