Among them, aluminum and nickel were the highest amounts. Aluminum in the present study increased with the length of brewing time. Excess amounts of this element can be harmful, but consuming a cup of tea a day does not have a toxic effect on the human body. The European Food Safety Authority (EFSA) sets the permissible weekly amount of aluminum from food at 1 mg/kg body weight. The aluminum content of tea infusions averages about 3 mg/10 g dried, ranging from 0.41 to 7.52 mg/10 g dried. This does not mean, of course, that the entire form of aluminum will enter into infusion or aqueous solution. This is because the tendency of aluminum migration depends on the form of the solvent and so the aluminum citrate forms become the most labile [62]. The ionic results after the extraction process are broken down into two sets of Tables 4-6.
