Tobacco plant is known to easily absorb heavy metals from soil and accumulate them in leaves. Part of these metals is transferred by the smoke into the human body, where they accumulate, damage the organs (mainly kidney and liver) and act as promoters in conjunction with carcinogens. Application of the essential elements can be effective in the prevention of toxicity and curative manner against the negative effects of toxic heavy metals. Reducing the harmful health effects of tobacco smoke is one of the major tasks of our research. Essential elements, first of all Zn and Fe, were added in an artificial way on tobacco-cut so that these elements should pass by the smoke to the smokers' bodies. The toxic metal content of our tobacco-sample was consistent with other data published in international literature (Cd: 1.55 mg g –1; Pb: 1.51 mg g –1). The transfer rates of these metals from tobacco-cut to smoke were significant (Cd: 15–34%; Pb: 8–20%). Twenty-thirty percent of the artificially added Zn and 10–23% of Fe transfer into the smoke was mainly in total particulate matter (TPM). The transmission of Zn to the smoke seems not to be dependent on temperature of smoke formation. However, higher Fe concentration was detected in smoke forming at 600 °C than at 900 °C. The more considerable part of Zn and Fe can be found in the ash. __
