Abstract
The concentrations of 28 toxic and other elements in cigarette tobacco of twelve brands commercially manufactured in the USA were determined using instrumental neutron-activation analysis. The elements determined were Al, As, Ba, Br, Ca, Ce, Cl, Co, Cr, Cs, Eu, Fe, Hf, K, La, Mg, Mn, Na, Ni, Rb, Sb, Sc, Se, Sr, Th, Ti, V and Zn. The concentrations of the determined elements in the American cigarettes were compared with the elemental concentrations reported for Iranian, Pakistani and Japanese brands. It was concluded that the concentrations of As, Br, Ca, Eu, K and Zn in the samples under investigation are lower than those reported for the analysis of University of Kentucky reference cigarettes, whereas the concentrations of Mn and Na are higher. The contents of Al, Cl, Co, Cr, Cs, Fe, La, Sb, Sc and Se are similar to those in the reference cigarettes.
