German society for pneumology and ventilation medicine (dgp) expects the world health organization (who) in the foreseeable future will recommend lowering the limits for nitrogen dioxide (no2). Currently, the who is advised by whether the limit applicable in the eu is still the current scientific knowledge, professor holger schulz said from helmholtz zentrum munchen world (edition of thursday, 7. Marz 2019). It should be amed that the who will suggest a reduction.
Schulz pays to the authors of the position paper, which the dgp had presented in november on the subject of air pollutants. In it, it is central: "healthful effects of air pollutants are well examined and occupied both in general population and in patients with different basic diseases."And:" another significant reduction in air pollutant burden is required and a reduction of the legal limits required."
Specifically, this means, according to schulz: "in terms of nitrogen dioxide, according to my view, a limit of 30 micrograms per cubic meter of air makes sense."The nitrogen dioxide limit is in the annual average at 40 micrograms per cubic meter of air and is based on who recommendations. Schulz stressed, it is the task of politics, not science to formulate new upper limits. Standard that air pollutants are harmful to health: "this is already detectable at values of 20 micrograms per cubic meter."
A group of more than 100 lung resources had a violent debate in january by doubting the health benefits of limits for nitrogen dioxides. Lifter the author of the opinion, the physician dieter kohler, but in the basic statement that the health risks due to nitrogen oxides and particulate matter and the limit values based on it were not scientifically greeted sufficiently.
