He stood still to his signature, says the Berlin-based pulmonary specialist Thomas herring. He is one of more than 100 physicians who have supported the lung doctor Dieter Köhler, published in January, paper. Therein, Köhler had set the current limit values for fine dust and nitrogen oxide in question and their science questioned. After a Search of the “newspaper” has the Köhler calculation and numbers given to error.

“based on My signature for the opinion of the President, Professor Köhler, to my knowledge, of his Interviews on the subject, have convinced me,” says herring. The Numbers in the opinion should be erroneous, for it will not change anything to the basic message of the paper. “My personal Position on the subject is from the perspective of a pulmonary physician experienced daily patients with the results of the destruction of the respiratory tract by the action of tobacco smoke.” Herring has no doubt that gases and other pollution of the air were from road traffic is harmful. He voice Köhler, however, in the statement, to establish that the data available on the toxicity of nitrogen oxides to thin, with measures such as Diesel-driving bans. There is currently “no scientific justification for the current limits,” argued the doctors ‘ group in the paper. That’s why you called for a revaluation of the previous studies.

Uncertain data

For herring, an expert in respiratory diseases due to asbestos, it is mainly a question of how the Federal government set their priorities. “If the state wants to in fact reduce the health hazards in relation to the respiratory system, he would have been at the forefront of the duty to reduce the risks due to tobacco consumption,” he says. 120000 tobacco deaths per year would have an estimated 6000 deaths due to air pollution. “In the case of the limit values, a certificate will be played the battle, although in contrast to the use of tobacco is not a safe data base exists,” says herring.

Uncertain data there are, according to the research of the “taz” in his much-cited opinion. The newspaper refuted the Central Argument köhler, the nitrogen dioxide pollution in inner cities, let with the pollutant content of cigarette smoke compare. The Köhler in the calculation, to be “serious”. Meanwhile, Koehler has confirmed the incorrect data in the “taz”.

köhler’s calculation, stating that smokers have the same fine dust dose that would be inhaled, an 80-Year-old non-Smoking in the course of his life is reached in less than two months. In truth, a smoker reaches the same load but only after six to 32 years.
