Risks of migration from traditional metallic teapots

Assuming realistic consumption scenarios (4 cups of natural tea or lemon tea per day, 15 minutes infusion) a daily intake of 1.7 to 320 μg of lead per kg bw was estimated for a person weighing 60 kg. Based on the EFSA established BMDL values (EFSA, 2010), this intake corresponds to a Margin of Exposure (MoE) lower to much lower than 1, indicating serious potential risks for public health. In addition, from subsequent experiments the exposure to lead from these teapots seems to be rather chronicle. The amount of lead migrating seems not to be related to the composition of the teapots, although... Mehr ...
