Air quality in Hanover: fine dust ensures health worries!

Air quality in Hanover: fine dust ensures health worries!

On June 14, 2025, the citizens of Hanover were not spared the challenge of air quality. The measuring station on Göttinger Straße, in the Linden-Süd district, recorded promising, but also worrying values ​​with regard to the air pollution. According to [haz] (https://www.haz.de/gesundheit/regional/hannover-wie-t-die-chufqualitaet-am-14-2025-feuzen-und- Mehraagwgcp4ddddddddddddddddddddddddddddddddddddddddddddddddddtype=valid_Amp), the air quality was based on the three main values: Fine dust, nitrogen dioxide and ozone to evaluate.

How do you measure air quality? This happens in Hanover as standard due to hourly mean values. The limit for fine dust particles (PM10) is 50 micrograms per cubic meter of air and may not be exceeded every year. The alarm bell value is clearly defined for nitrogen dioxide, fine dust and ozone: "very bad" values ​​above 200 μg/m³ or 100 μg/m³ for fine dust, while ozone above 240 μg/m³ is also one of the problem children.

air quality and its effects

The last measurements make it clear that fine dust particles represent a serious problem. In the EU alone, they lead to 240,000 premature deaths annually. A significant part of the fine dust emissions is released, especially on New Year's Eve, when the air is loaded by fireworks. A total of around 2050 tons of fine dust are created by fireworks, 1500 tons of which are incurred on one evening, which can significantly impair air quality.

But what does that mean specifically for the Hanover citizens? In the case of "very bad" air quality, the authorities advise caution: sensitive people should avoid physical exertion outdoors. With “poor” quality, less sensitive people should also pay particular attention to their activities. With “moderate” values, short -term health effects are unlikely, but long -term exposure can become a problem. A "good" or "very good" air quality, on the other hand, is ideal for everyone who likes to stay outside.

A call to attention

The city administration sees itself as responsibility to monitor air quality and to warn the citizens when the values ​​become critical. According to N-AG, people are encouraged to adapt to fine dust and to pursue the reports on air quality regularly. This is particularly important because the air pollution fluctuates over the year and different weather conditions can influence the quality.

everyone should keep in mind how important it is to protect themselves from health risks. Find out regularly about the current air values ​​and act accordingly so as not to endanger your health and those of your fellow human beings.
