“…Other studies reported similar values for As (40%) [30] and for Pb (24-37%) [31,32]. For Zn, two studies reported values ranging from 7.6 to 18.5% [33,34], which is slightly below the range obtained in this study (13-21%).…”

Tobacco use kills millions of people every year around the world. The current level of 11 metals in tobacco was determined and their transfer rate to cigarette smoke was calculated as the difference between the total metal content in cigarettes and the amount present in its ashes. The metals content was also determined in the lung tissue of smokers and non-smokers in order to evaluate the marks that smoking leaves in this tissue. Metals content in tobacco ranged from less than 1μg/g (Co, Cd, Pb, As and Tl) to several hundreds of μg/g (Al, Mn and Ba). The highest transfer rate from tobacco to cigarette smoke was found for Tl (85-92%) and Cd (81-90%), followed by Pb (46-60%) and As (33-44%). Significantly higher levels of As, Cd and Pb were found in the lung tissue of smokers compared to non-smokers, showing that smoking results in an increase of these metals in the lungs and that they contribute to the carcinogenic potential of cigarette smoke. This study presents important data on current metals content in tobacco and its transference to cigarette smoke and provides evidence of their accumulation in smokers' lung tissue.

“…Co content is nearly same in all samples (0.9 AE 0.1 mg per cigarette), and is lower than Cd. Co tends to form a metal carbonyl which is highly toxic (Nada et al 1999). However, Fe and Co concentrations in tobacco in this work are much lower than those previously reported in the literature.…”

In this study, the concentrations of Co, Ni, Fe, Cu, Mn, Pb, Cr, and Cd were determined in 15 cigarette brands from Turkey by flame atomic absorption spectrometry (FAAS). A wet digestion method was employed to cigarette samples. The mean values obtained for Co, Ni, Fe, Cu, Mn, Pb, Cr, and Cd were 1.2, 4.1, 134, 14, 66, 3.7, 5.0, and 1.1 mg g À1 , respectively, i.e., in the order of Fe > Mn > Cu > Cr > Ni > Pb > Co > Cd. The results were compared with the literature values for other international cigarette brands.

“…Tobacco plants have been shown to accumulate high levels of cadmium, lead, zinc, nickel, copper, iron, manganese, etc; [18][19][20][21][22] hence, there are many reports for these elements in cigarette tobacco and cigarette smoke. 1,23,24 While it is noteworthy to discuss the health effects associated with tobacco use and to acknowledge that tobacco use on any level poses a health hazard, [25][26][27][28] differentiation between the different smoking styles and the various tobaccos is necessary to begin to authoritatively address actual health implications. 29 To do so in the most rigorous fashion requires many more samples than could be reasonably done in this initial study, which is intended to provide an initial report to stimulate additional research in this important area.…”
