Fine dust and nitrogen oxides – Pulmonary physicians with dyscalculia – Health

  • The position of the lung doctors in January marginalized the health hazards of nitrogen oxides and particulate matter.
  • Now the daily has taz Calculation error found in the argument.
  • The arguments of the pulmonary physicians have never been scientifically substantiated, regardless of the newly discovered turn-around.

Two years ago, Dieter Köhler began to peddle his idea. In e-mails with a conspiratorial undertone, the physician turned to journalists, wrote of uncomfortable truth search and put in more emails that is that with the fine dust and the nitrogen oxides everything is so half wild. He described the reports on the health effects of air pollutants as "fake news". Journalists who did not want to report on his hair-raising calculations and comparisons, he assumed, the topic "want to keep silent," like most ".

It took a while before he was heard by German newspapers, radio stations and talk shows. Last year, he was able to spread his calculations and his views on limits. His popularity culminated in a paper in January in which he and a good hundred other pulmonary physicians again marginalized the health risks of nitrogen oxides and particulate matter. In addition, the group criticized large-scale population studies that quantify health damage caused by air pollutants. By way of comparison, the signatories of the Opinion drew heavy smokers who inhale far greater levels of pollutants from cigarettes than people who travel by road and yet do not "die off after a few months." Now the daily newspaper taz has revealed that Köhler and his followers have miscalculated.

According to Köhler's argument, a person living on a busy street for life gets as many pollutants as a smoker can do in a few months. Inspired by a reader's note, the taz reckoned and came to another rather frightening conclusion: "Anyone living on a busy street breathes as much nitric oxide during a lifetime of 80 years as a heavy smoker does in six to 32 years." Asked about these and other miscalculations Kohler should have said to the taz: "This has not noticed anyone yet." Apparently also none of the other 100 signatories and signatories of his opinion. Against the SZ Koehler said, not only he, but also the taz had miscalculated, and he will soon publish the corrected calculation.

But regardless of the now discovered payment turnarounds and Köhler's questionable comparisons, his arguments were scientifically sound. The criticism of international experts on the paper by Dieter Köhler and his three most important co-authors, including Matthias Klingner, head of the Fraunhofer Institute for Transportation and Infrastructure Systems in Dresden, and the head of the Institute of Piston Machines at the Karlsruhe Institute of Technology was correspondingly harsh , Thomas Koch, who used to develop engines for Daimler. The International Lung Society Forum, FIRS, said in a statement that the existing EU-wide limits would not be mitigated. "Although the lung is most affected by air pollution, it also damages other organ systems and worsens chronic diseases," the text says. Cancer, heart disease, neonatal damage and dementia are associated with air pollution, "especially particles with a diameter of less than 2.5 microns and other diesel exhaust gases are responsible." Damage would be "even below the limits."

Köhler's more than 100 fellow members are members of the German Society for Pneumology and Respiratory Medicine (DGP), whose 3800 members received their position paper with a request for signature. The signatories also opposed a 50-page position paper from their own society published in 2018, which states: "Harmful effects of air pollutants are well documented in the general population as well as in patients with various underlying diseases." Above all, media attention was paid to Köhler's minority opinion. On this Thursday, the DGP and representatives of three other German societies repeated in a statement that despite all knowledge gaps, the existing limit values ​​for nitrogen oxides should be strictly adhered to.
