I've always wondered about that, I have a few mugs I use daily and they have tiny little cracks inside. The results say coffee seems to have more lead than tea, and some of the levels were above guidelines. The lead concentrations were dependent on the cup used. But blood lead levels did not increase above regulatory or guidance values.
