A Copper Cube a Day—How long could the copper used for a laptop display supply the body with copper as a micronutrient?
The animation shows how many daily rations of copper are contained in the LCD display that we researched. This puts everyday electrical devices into a different context of consumption.
Copper in the LCD laptop module under consideration: 15 g¹
Average daily requirement of a human for copper: 1.25 mg/day²
Calculation: Daily ration of copper in the LCD laptop module: 15 g / 0.00125 g/day = 12,000 days
