Abstract: 
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 (5.36±0.49 ppm) concentrations were found in the M1, S, M2, and M2 teas, respectively; whereas, the maximal amount of As (0.287±0.007 ppm), Pb (0.228 ± 0.002 ppm), Cd (0.101±0.040 ppm), and Cu (37.4±0.53 ppm) concentrations were found in the D, A1, M1, and D teas, respectively.Considering the present safety standards, the tea versions selected in this study were determined to be fit and safe for human consumption.
