abstract


By stripping voltammetry method it was investigated zinc, cadmium, lead, copper and mer-cury content samples of cigarette smoke. It was established that in cigarette smoke the heavy metal content is less than in tobacco cigarettes. It is shown that the ratio of the amount of heavy metals contained in the cigarette smoke and in tobacco, is not the same and depends on the nature of metal and names of cigarettes items. This may be due to differences: temperature conditions of combustion of tobacco, the sorption capacity of the ashes of tobacco in relation to heavy metals, the ability of the materials of filter cigarettes to delay allocating the smoke heavy metals.

It is marked also, that the filters of all studied names of cigarettes in one or another degree catch in the process of smoking of Cd, Pb, Cu and Hg, however for the names of some cigarette filters not only Zn does not detain but also are the additional source of receipt of this metal in ciga-rette smoke.
