Air quality in Stralsund: Alarming fine dust values on April 11th!

Air quality in Stralsund: Alarming fine dust values on April 11th!

Stralsund, Deutschland - On April 11, 2025, the air quality in Stralsund, especially at the Stralsund-Kneeperdamm measuring station, is examined exactly. The current recording shows the concentration of fine dust particles (PM10) per cubic meter of air, whereby the limit for PM10 is 50 particles, which may be exceeded a maximum of 35 times a year. The air quality is measured in three main categories: fine dust, nitrogen dioxide and ozone, each have different limit values. According to Ostsee-Zeitung the air conditions are classified.

The different status of the air quality are as follows:

• "very bad": nitrogen dioxide> 200 µg/m³, fine dust> 100 µg/m³, ozone> 240 µg/m³.
• "bad": nitrogen dioxide 101-200 µg/m³, fine dust 51-100 µg/m³, ozone 181-240 µg/m³.
• "moderate": nitrogen dioxide 41-100 µg/m³, fine dust 35-50 µg/m³, ozone 121-180 µg/m³.
• "good": no health -related effects to be expected.
• "very good": best conditions for outdoor activities.

recommendations in poor air quality

The Ostsee-Zeitung also gives Recommendations for sensitive people, depending on the air quality status. With "very bad" air quality, physical activities should be avoided outdoors, while exhausting activities should be put up with "poor" air quality. With "moderate" air quality, short -term health effects are unlikely, but sensitive people can still be affected.

The situation is particularly delicate during the turn of the year, where fireworks leads to an increase in fine dust pollution. Statistics show that around 2050 tons of fine dust are released by fireworks annually; From this, there are 1500 tons (75%) on New Year's Eve. The weather conditions can influence the distribution of fine dust, which can increase the stress.

long -term trends and health effects

The Federal Environment Agency states that fine dust measurements in Germany have been recorded for PM10 since 2008 and for PM2.5. In the past few decades, air quality in Germany has improved considerably, which has dropped to 15 to 20 µg/m³ in the 1990s.

Despite these progress, the health risks of air pollutants are not to be neglected. According to Environmental Federal Agency long-term fine dust pollution can promote a variety of health problems such as cardiovascular diseases and lung cancer. The WHO has published new guidelines in 2021 that state that the current limit values are not sufficient to completely avoid health risks.

The health effects of fine dust are far -reaching and also include irritation of the mucous membranes and an increased tendency to thrombosis. PM10 can penetrate the nasal cavity, while PM2.5 can penetrate into the bronchi and lung bubbles. Ultrafine particles that can get into the lung tissue and blood circulation are particularly problematic.

Overall, it becomes clear that despite a positive development of air quality, the risks of air pollutants continue to exist in recent years. Future measures must aim to minimize these risks and further improve air quality.
