The contents of various elements in green, black, oolong, and pu-erh teas were measured by ICP-MS. The dependence of the dissolution rate of each element on the extraction time and the number of infusion was determined. By calculating the estimated daily dietary intake as a result of consuming 15 g of tea leaves a day, it was revealed that Cr and Mn exceeded the adequate intake for one day.
