Les différents courants de la fumée de tabac
Burning tobacco releases thousands of substances, many of which are toxic, from the tobacco itself or induced by chemical reactions related to its combustion. Tobacco smoke is a source of pollution composed of three different currents, characterized by specific chemical products. There is the primary current, the secondary current and the tertiary current. The primary current is the smoke that the smoker inhales directly. It is filtered and exhaled by the smoker. The secondary current corresponds to the smoke that is released from the cigarette between puffs. It comes from the incandescent tip, from the smoke that passes through the paper and from the smoke that is released from the end of the filter when it is no longer on the smoker's lips. The smoke that is released from the cigarette between two puffs is much more dangerous than that inhaled by the smoker himself because it contains more toxic substances (carbon monoxide, nitrogen oxide, etc.) and carcinogens. Combustion releases a complex mixture of gases and fine particles composed of more than 4,000 different elements, including more than 43 carcinogens, including benzene, butadiene, nitrosamines and formaldehyde. The tertiary current corresponds to the smoke exhaled by the smoker. This is ambient tobacco smoke that has oxidized with nitrous acid present in the environment to create carcinogenic agents. The chemicals released by cigarette smoke react with the chemical constituents of fabrics and materials present inside the home (curtains, sofas, etc.). Tobacco smoke inhaled involuntarily is just as dangerous as that which a smoker inhales: this is passive smoking.Read “Smoke, the main indoor air pollutant”©Tobacco Free Generation
