Evaluating the Arsenic, Cadmium, Lead, and Copper levels in certain imported tea samples consumed in Iran
Journal of Advances in Environmental Health Research
Seven majorly consumed brands of several teas (A1, A2, M1, M2, S, D, and C teas) were selected for the present study. In this study, the heavy metal contents including copper (Cu), cadmium (Cd), arsenic (As), and lead (Pb) were assessed in the black tea samples consumed in Iran. The content of the heavy metals in the samples was analyzed using atomic absorption spectroscopy (AAS). Notably, the minimal amount of As (0.043 ± 0.006 ppm), Pb (0.040 ± 0.005 ppm), Cd (0.016 ± 0.001 ppm), and Cu (5.36doi:10.22102/jaehr.2018.102510.1045 doaj:8a22fa3c30d74cf4a5fe4763a49dfa20 fatcat:bty3un7vrrhwdpk7mimeb24o7e
