[Biomarkers of tobacco smoke].
In order to estimate the exposure of passive and active smokers to tobacco smoke one can use the questionnaire method or laboratory examination of chemical compounds being widely accepted exposure biomarkers. Substances that make such biomarkers include some of the tobacco smoke components and its metabolites formed in the body. The study discusses two groups of biomarkers. First, includes substances that serve as exposure markers of carcinogenous properties (metabolites of polycyclic aromatic hydrocarbons, N-nitrosamines, trans,transmuconic acid, S-phenylmercapturic acid). Second group includes substances which role is limited to the evaluation of exposure to tobacco smoke (nicotine, cotinine, anatabine, anabasine, trans-3'-hydroxycotinine, thiocyanate, carboxyhemoglobin, carbon monoxide). Sensitivity and specificity of biomakers used were evaluated, their concentration ranges in physiological fluids in non-smokers, passive-, and active smokers. The simplicity of the examination method was evaluated. Articles published during last two decades indicate that the substance that have all features that make it the most appropriate biomarker is cotinine. It can be assessed in plasma and in urine of smokers and persons exposed to environmental tobacco smoke.
