The atomic emission spectrometry with inductively coupled plasma (ICP-AES) technique was used for determination of trace elements presence and their contents in Camellia sinensis teas and its tea mixtures. Samples were collected from macedonian market originating from Macedonia, Serbia and Poland. For sample preparation
microwave digestion system using HNO3 and H2O2 was applied. The following trace elements: Al, Ba, Ca, Cd, Cr, Cu, Mn, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sr, V and Zn were determined in several types of tea products. The results showed that K, Ca and Mg were the most abundant elements (10287 mg/kg, 6072 mg/kg, 3072 mg/kg, respectively) and Mo and V were not detected. The elements: Na and Li were detected at the widest ranges. As, Cd and Pb were detected at allowed quantities. The results for the content of all analyzed elements showed the expected variation among sampled teas and therefore
these tea products may not produce any health risks for human consumption as sources of toxic metals
