Why are smoke particles floating
Smoking is by far the greatest particulate matter pollution!
The EU limit values for air pollutants do not have a sufficient scientific basis and are disproportionate. Cigarette smoke, for example, contains a million times as much fine dust
Fine dust is considered toxic and, according to estimates by the EU Commission, costs many Europeans their lives every year. With a size of less than 10 µm, fine dusts can float in the air (so-called airborne dusts) and can be inhaled by humans, so that the fine dust particles can get into the lungs and pass into the body via the alveoli. So they advance into the liver, among other things.
, however, not all smokers drop dead after a few months! The pulmonologists of the Association of Pneumological Clinics (VPK) criticize this and illustrate the actual situation using a calculation example.
The legal limit values for nitrogen dioxide (NO²) and fine dust set in the EU do not have a sufficient scientific basis. “If inhaling nitrogen dioxide (NO²) in a dose of more than 40 micrograms per cubic meter were actually harmful to health - as the EU limit value implies - then all smokers would have to drop dead after a few months! But that is not the case, although tobacco smoke is by far the worst fine dust, ”says Prof. Dieter Köhler, former board member of the Association of Pneumological Clinics (VPK), former President of the German Society for Pneumology-Pneumology
Respiratory and pulmonary medicine (pulmonology) is a branch of internal medicine that deals with the prevention, detection and specialist treatment of diseases of the lungs, bronchi, mediastinum (middle skin) and pleura (pleura and lung).
and respiratory medicine (DGP) and long-standing medical director of a specialist clinic for lung diseases. “It's not about playing down air pollutants, but rather about correctly and evidence-based determining the amount from which they are actually hazardous to health. The number of premature deaths published in the media, allegedly caused by increased nitrogen dioxide pollution, is based on projections in epidemiological studies in which correlations were improperly reinterpreted as causalities without possible further influences (so-called confounder such as smoking, passive smoking, alcohol consumption, lack of exercise, diet, etc.) should be adequately taken into account ", criticizes Prof. Köhler, who also did his habilitation on the subject of deposition and elimination of aerosols (dusts and droplets) in the lungs.
Nitrogen dioxide pollution of a non-smoker on a busy street corresponds after one year to that of a smoker after one week!
A calculation example should illustrate the actual situation: With a single cigarette a smoker inhales up to 1000 micrograms of nitrogen dioxide (NO²). A cigarette consumption of one pack a day adds up to around 20,000 micrograms of NO², and after a month around 600,000 micrograms. After one year, the person concerned has accumulated 7.2 grams of NO² through smoking alone. “If, on the other hand, a non-smoker stood around the clock on a busy street and inhaled 50 micrograms of NO² per cubic meter (i.e. more than the limit value specified), he would have inhaled 9 cubic meters of air and thus 450 micrograms of NO² after 24 hours. After one year that equates to 164,000 micrograms of NO². In this example, the smoker inhales this amount in eight days! If exceeding the limit values were actually as causing death as is implied, smokers would have to have a life expectancy of only a few months, ”concludes Prof. Dr. Martin Hetzel, board member of the VPK and chief physician at a lung clinic in Stuttgart not far from the Neckartor measuring point.
Cigarette smoke contains a million times as much fine dust
In Germany, certainly not a single person has died from nitrogen dioxide, emphasize the lung specialists at the VPK. The situation is very similar with fine dust: Here, the legal limit was set at 50 micrograms per cubic meter, with cigarette smoke containing a million times as much fine dust. “However, smokers usually only die after 40 to 60 years - then they have inhaled a dose of fine dust and many other toxic substances that is tens of millions of times higher,” confirms Prof. Koehler. Further arguments can be found in various interviews with Prof. Köhler - z. B. in Cicero.de and Stern.de - can be found.
