Abstract：After the digestion of cigarettes and its ash are digested with concentrated nitric acid and perchloric acid, the change in mineral elements (Ca, Mg, Cu, Fe, Zn, Mn, Ni, Co, Cr, Pb and Cd) content in the cigarette and its ash were determined by flame atomic absorptionspectrophotometry. The experimental results showed that there were differences between the cigarette (tobacco) and its ash, especially, the contents of Pb and Cd harmful to human health in the ash are lowed 26.4% and 44.2%, respectively. It is concluded that a part of Pb and Cd in the cigarette passes through the human lung respiration and air environment.
