Abstract

Background: High intake of some ELEMENTS results in TOXICITY for human. Investigations has been shown that in some species of TEA (Camellia sinensis L) the level of certain ELEMENTS are higher than standard. This study aimed to measure the amount of K, Cu, Pb, Ni, Na, Mg, Zn, Ar, and Se ions in black TEA.Matereials and Methods: Pre-analysis treatment of TEA samples (trade marks Tala, Gulabi, Ahmad, Golestan, and the bulk brand of Ceylon) and the measurement of ions were carried out using acid digestion and atomic-absorption spectrometry techniques, respectively.Results: The minimum and maximum means for K, Mg, Zn, Cu, Pb, Ni, and Na ions in the examined samples were (18062±1095 and 19364±6120 mg/kg), (1±0 and 157±20 mg/kg), (21±3 and 31±9 mg/kg), (17±0 and 21±0 mg/kg), (0.485±0.249 and 0.151±0.066 mg/kg), (0.485±0.249 and 0.151±0.066 mg/kg), (2.907±0.077 and 6.987±1.270 mg/kg), (1±0 and 157±20 mg/kg), respectively. Se and Ar levels are samples were non-detectable.Conclusion: The availibility of high levels of K and Mg ions in the examined black TEAs is in agreement with a traditional medicine hypothesis signifying the use of TEA to decrease the blood pressure.
