Tobacco smoke contains a barely manageable abundance of chemical compounds and has various effects on the organism.
Already in the 50s extensive investigations were carried out to clarify the chemical composition of the tobacco smoke. To date, more than 3800 individual components have been identified. 40-50 compounds contained in tobacco smoke are considered carcinogenic.
The problem: the ingredients
Furthermore, substances with irritant or allergenic properties are also present in the tobacco smoke. Since these substances are contained not only in the mainstream smoke, but also in the sidestream smoke and in the exhalation air, they get into the indoor air. The passive smoker harmful by-pass smoke contains much higher levels of carcinogenic substances than the mainstream smoke. Investigations showed a 10-fold higher proportion of these compounds. In view of the widespread use and the large amount of tobacco used as a stimulant, tobacco smoke is therefore considered to be the most important and probably the least harmful source of indoor pollution.
