Air quality in Kiel: Fine dust warning at the end of the year!
Find out the current air quality in Kiel on October 29th, 2025: measured values for fine dust, nitrogen dioxide and ozone.
Air quality in Kiel: Fine dust warning at the end of the year!
What is the air quality like in Kiel on October 29, 2025? In Bahnhofstrasse, one of the most important measuring stations, the values for Fine dust particles (PM10) recorded per cubic meter of air. The limit value for PM10 is 50 micrograms per cubic meter and this may be exceeded a maximum of 35 times in a year. What is the current situation? How do the other values relate to air quality?
Air quality in Kiel is monitored based on three main values: fine dust, nitrogen dioxide and ozone. These pollutants have different limits that determine the health status of the air. According to data from the Federal Environment Agency, it is important to note that the most health-critical concentration among the three pollutants measured determines the overall result of the air quality index. This index ranges from 1 (very good) to 5 (very bad) and is particularly important for recommended risk groups such as children, the elderly and people with previous illnesses.
The exact measurements
The last measurement in Kiel showed that the air quality varies regionally. The limit values for assessing air quality are summarized here:
- Sehr schlecht: Stickstoffdioxid > 200 μg/m³, Feinstaub > 100 μg/m³, Ozon > 240 μg/m³.
- Schlecht: Stickstoffdioxid 101-200 μg/m³, Feinstaub 51-100 μg/m³, Ozon 181-240 μg/m³.
- Mäßig: Stickstoffdioxid 41-100 μg/m³, Feinstaub 35-50 μg/m³, Ozon 121-180 μg/m³.
A closer look at the values in Kiel also shows that the current air pollution is given in micrograms per cubic meter, with the measurement of fine dust levels being carried out as an hourly moving daily average. The fact that around 240,000 premature deaths are caused by particulate matter every year in the EU highlights the importance of regular monitoring and action to improve air quality.
Recommendations for the population
How should the population behave at different air quality levels? According to the recommendations, which are based on air quality values, the following applies:
- Bei sehr schlechter Luftqualität sollten empfindliche Personen körperliche Anstrengungen im Freien vermeiden.
- Bei schlechter Luftqualität wird geraten, anstrengende Tätigkeiten im Freien zurückzustellen.
- Bei mäßiger Luftqualität sind kurzfristige gesundheitliche Auswirkungen unwahrscheinlich.
- Bei guter Luftqualität sind keine gesundheitlichen Nachteile zu erwarten.
- Bei sehr guter Luftqualität bieten sich die besten Voraussetzungen für Aktivitäten im Freien an.
The problem of fine dust pollution from New Year's Eve fireworks is particularly blatant. Around 1,500 tonnes of fine dust are released every year, which corresponds to an impressive 75% of the annual amount. This fact is also a topic discussed by many health experts, as the fine dust particles from fireworks rockets are tiny and harmful to health.
The spread of fine dust is also influenced by weather conditions, meaning that regular measurements and adjustments to traffic management or industrial policy are absolutely necessary in metropolitan areas such as Kiel. It remains to be hoped that the cooperation between the various institutions in the field of environmental protection will continue to be successful.
