In this study, was carried out determine by flame atomic absorption spectrometry of metals Cu, Mn, Zn, Fe, Pb, Cr, Co, Cd and characterizations by gravimetric techniques (moisture and ash content) and electrochemistry (pH) in the two most consumed brands of cigarettes legally in Brazil. Results of recovery of the analytes were between 91.5 to 111.4% with relative standard deviation of 1.24 to 4.53%. Tests conducted on cigarette brands showed average moisture content of 13.0%, ash 14.1% and pH 5.0. The order of highest concentration of metals was Fe > Mn > Zn > Cu > Pb > Co > Cr > Cd the results show that the examined cigarette brands have higher concentrations of Cd forty-four times the legalized cigarettes found in the United States, Pb twenty times that found in cigarettes in Poland.Downloads
