Súhrn: Trace element contents of powdered beverages from Turkey were determined by atomic absorption spectroscopy after microwave digestion. Verification of the method was demonstrated by analysis of standard reference material. Trace element contents in powdered beverage samples were 0.10–1.33 mg.kg-1 for copper, 0.22–1.90 mg.kg-1 for manganese, 0.39–4.19 mg.kg-1 for iron, 0.22–4.54 mg.kg-1 for zinc, 0.11–0.47 mg.kg-1 for selenium, 3.21–71.5 µg.kg-1 for chromium, 20.9–80.1 µg.kg-1 for aluminium and 6.12–217 µg.kg-1 for nickel. The results were compared with literature data and levels set by legislative documents.
