Copper content of tea.
Published data for copper content of tea are contradictory. To resolve the issue, various brands and flavors of four different types of tea were prepared in two kinds of containers and analyzed for copper. Copper concentrations averaged from 0.14 p.p.m. for herbal and instant teas to 0.19 for brewed regular tea, plain or flavored. All concentrations were well below a previously reported value for tea as a beverage.
