Air quality in Rostock: Alarming fine dust levels at Holbein-Platz!
Current air quality data in Rostock on July 14, 2025: Focus on fine dust, nitrogen dioxide and ozone - what about health?
Air quality in Rostock: Alarming fine dust levels at Holbein-Platz!
On July 14, 2025, air quality in Cologne will be an important issue for citizens. The concentration of fine dust particles (PM10) per cubic meter of air is regularly recorded at measuring stations, such as at Holbein-Platz in Rostock. Loud ostsee-zeitung.de The limit value for PM10 is 50 particles per cubic meter and this may not be exceeded more than 35 times per year. Some level of particulate matter is inevitable, and air quality is assessed by three key factors: particulate matter, nitrogen dioxide and ozone.
The EU has set clear limit values for a differentiated view of air quality. Air quality is considered “very poor” when nitrogen dioxide levels exceed 200 μg/m³, and fine dust levels exceed 100 μg/m³. “Poor” is the category for nitrogen dioxide values between 101 and 200 μg/m³ and fine dust values of 51 to 100 μg/m³. “Moderate” air quality is nitrogen dioxide levels between 41 and 100 μg/m³ and fine dust levels of 35 to 50 μg/m³.
Current measurements and trends
Data shows that air quality often struggles in urban areas. Loud Umweltbundesamt.de The annual average PM10 values in Germany are currently between 15 and 20 µg/m³ – a decrease from 50 µg/m³ in the 1990s. Due to the high density of measurements in metropolitan areas, traffic and industry are in the crosshairs as they are the most common emitters. Nevertheless, the situation has improved: Since 2012, the annual limit of 40 µg/m³ has not been exceeded at any measuring station.
Particularly striking are the weather conditions, which play a major role in fine dust concentrations. Higher values can be expected in dry winters or hot summers. Critical days can lead to significant pollution in metropolitan areas, for example on January 23, 2017, when a peak value of 176 µg/m³ was reached. The health effects of high levels of fine dust should not be underestimated; they can result in respiratory diseases and cardiovascular diseases. The risk varies depending on the particle size.
Recommendations for citizens
The population is encouraged to remain active when air quality deteriorates. If the air is classified as “very bad”, sensitive people should avoid physical exertion outdoors. If the quality is “poor”, it is advisable to reduce strenuous outdoor activities. While “moderate” quality means that short-term health effects are unlikely, caution is still advised for those with specific sensitivities. With “good” air, however, no health concerns are to be expected, and with “very good” air quality there is nothing to be said against outdoor activities.
Regarding air pollution on New Year's Eve, it was found that fine dust from fireworks increases, but is largely insignificant compared to annual pollution. Every year, fireworks release around 2,050 tons of fine dust, 75 percent of which occurs on New Year's Eve. This can produce additional stress if weather conditions are not optimal. In times of increasing air pollution, it is important to keep an eye on your own well-being and health.
