Resumo: | Camellia sinensis L. is a small tree in the Theaceae family. From its leaves is produced a tea, which is the second most consumed non-alcoholic beverage in the world. The tea of this plant can bring several health benefits, however, some elements present in the leaves of Camellia sinensis L. are potentially toxic, for example, As, Cd and Pb; since they are among the ten chemical substances of major health risks. Thus, the objective of this work was to determine the concentrations of As, Cd, Cr, Cu, Pb and Zn by inductively coupled plasma optical emission spectrometry (ICP OES) after acid digestion of commercial samples of black tea from the plant Camellia sinensis L. acquired in supermarkets from Campos dos Goytacazes (Brazil). The detection limits for the elements were 0.5 mg kg−1 for As; 0.003 mg kg−1 for Cd; 0.02 mg kg−1 for Cr; 1.2 mg kg−1 for Cu; 0.09 mg kg−1 for Pb and 0.04 mg kg−1 for Zn. The concentrations found of the potentially toxic elements Cd and Pb in the black teas of Camellia sinensis L. are below the concentrations established by ANVISA (0.60 mg kg−1 and 0.40 mg kg−1, respectively). |

De sus hojas se produce el té, la segunda bebida no alcohólica más consumida en el mundo. El té de esta planta tiene varios beneficios para la salud, sin embargo, algunos elementos presentes en las hojas de Camellia sinensis L. son potencialmente tóxicos, por ejemplo, As, Cd y Pb; ya que se encuentran entre las diez sustancias químicas con mayores riesgos para la salud. Así, el objetivo de este trabajo fue determinar las concentraciones de As, Cd, Cr, Cu, Pb y Zn mediante espectrometría de emisión óptica de plasma acoplado inductivamente (ICP OES) después de la digestión ácida de muestras comerciales de té negro de la planta Camellia sinensis L. adquirida en supermercados en Campos dos Goytacazes (Brasil). Los límites de detección de los elementos fueron de 0,5 mg kg−1 para el As; 0,003 mg kg−1 para Cd; 0,02 mg kg−1 para Cr; 1,2 mg kg−1 para Cu; 0,09 mg kg−1 para Pb y 0,04 mg kg−1 para Zn.
