Hildesheim is struggling with bad air: fine dust levels in the red!
Air quality in Hildesheim is causing serious concern today, December 26, 2025. A look at the current measured values shows that several stations in the city clearly exceed the limit values for fine dust (PM₂,₅). The highest measured value is 38 µg/m³, which means the air quality is classified as “poor”. According to news.de, the air quality index (LQI) is in the red zone, which indicates a serious health risk.
But what does that mean specifically? The air quality index classifies values as follows: A value of 0 to 5 µg/m³ has a positive influence, while values of 31 to 50 µg/m³ represent a hazard. Above 50 µg/m³ it is considered a high risk. According to current data, risk groups such as asthmatics and older people in particular should avoid outdoor exercise.
Hildesheim and air pollution
The situation in Hildesheim is just the beginning. The air quality history shows that the air is not only unhealthy for sensitive groups, but also affects the entire population. Here, according to iqair.com, the current values are at a level that should trigger an alarm. The air quality is classified as poor, particularly between 9 p.m. and 10 p.m., which should affect ventilation during this time as well as delayed outdoor activities.
The measuring station in Hildesheim even ranks at the top of the real-time AQI⁺ city rankings for Germany and impressively shows how serious the situation is here. In the coming days, attention will remain on this development, as the supply of clean air has remained a pressing issue in recent decades.
Causes of air pollution
But why is the air quality in Germany – and especially in Hildesheim – so bad? The causes are diverse. A large proportion of air pollution comes from industrial plants, coal-fired power plants, as well as from road and air traffic. Agriculture and the use of fossil fuels also contribute, as Statista reports. Although overall emissions have been reduced by around 64% over the last 30 years, there are still a number of cities that regularly exceed the limits.
Cities like Munich, Ludwigsburg and Essen show that we still have a long way to go. While the numbers in Hildesheim seem alarming, the connection to regional and global air quality should not be forgotten. The exchange of solutions to improve the quality of life in cities like Hildesheim remains urgently necessary.
This makes it all the more important that our awareness of the air we breathe is sharpened today. It is up to us to act and take responsibility to improve air quality for future generations.
