Dirty air in Kiel: fine dust values ​​reach alarming height!

Kiel, Deutschland - On May 4, 2025, a current analysis of the air quality in Kiel shows that the measuring station on Bahnhofstrasse is detected by fine dust particles (PM10) per cubic meter. According to the data, the limit for PM10 has 50 micrograms per cubic meter of air, which can be exceeded 35 times a year, such as kn-online.de reported. The air quality is evaluated by three values: fine dust, nitrogen dioxide and ozone.

The limit values ​​are set as follows: values ​​above 200 μg/m³ for nitrogen dioxide, 100 μg/m³ for fine dust and 240 μg/m³ for ozone are considered very bad; Between 101 and 200 μg/m³ for nitrogen dioxide, 51 and 100 μg/m³ for fine dust as well as 181 and 240 μg/m³ for ozone as bad. Moderate values ​​are between 41 and 100 μg/m³ for nitrogen dioxide, 35 and 50 μg/m³ for fine dust and 121 to 180 μg/m³ for ozone. The measurement takes place as an hourly means for nitrogen dioxide and ozone or every hour sliding daily remedy for fine dust.

health recommendations and effects of air quality

In the EU, around 240,000 early deaths are registered by fine dust annually. Recommendations in poor air quality are different: In the case of very poor quality, sensitive people should avoid physical exertion outdoors, while strenuous activities should be avoided in poor quality. With moderate quality, short -term health effects are unlikely, but long -term effects could occur.

An important aspect is the influence of the New Year's fireworks on the fine dust pollution. Although it can lead to an increase in fine dust values ​​after midnight, it is considered not significant compared to year -round stress. Fireworks released around 2050 tons of fine dust annually, with 1500 tons (75%) being released on New Year's Eve.

In addition, temperature and wind speed over 24 hours were examined. This shows that the temperature increases up to 11 ° C, while the wind speed fluctuates between 3.6 and 25.2 km/h, like iqair.com . Such data are relevant to evaluate the air quality and to understand the effects of weather conditions on the air distribution.
