TLDR: > Overall, the potential for lead ingestion from contaminated ceramic mugs is minimal when compared to other sources, such as food. The Agency for Toxic Substances and Disease Registry (ATSDR) reported that the average daily intake of lead from food sources in the general population is approximately 56.5 μg/day (ATSDR 2007a). In comparison, the maximum daily lead intake from drinking 3.3 eight-ounce cups of coffee based on the data collected in our study resulted in a dose of 6.71 μg, over eight times less than the average daily lead intake from food. Nonetheless, exposure to lead should be minimized to the extent possible.
