Alarming air quality in Bottrop: Measured the highest fine dust values!

On January 11, 2025, the fine dust pollution in Bottrop exceeded the permissible limit. At the Bottrop-Welheim measuring station, 28 µg/m³ were measured, which classified the air quality into the red area and classified it as "bad". The normal range for fine dust is 0 to 25 µg/m³, which is why the increased stress is worrying, especially for sensitive groups of people, which include asthmatics and people with previous illnesses.

It is known that fine dust (pm₂₅) can damage the respiratory tract. The measuring station in Bottrop-Welheim is affected by transport and in particular. It is recommended for risk groups to avoid exhausting outdoor activities to stay in well-air-conditioned interiors and, if necessary, to wear FFP2 masks in areas with permanently poor air quality.

historical fine dust values ​​and trends

The highest daily means for fine dust in Bottrop in the past three months show a worrying development:

• 29.12.2024: 25 µg/m³ (🟡)
• 28.12.2024: 25 µg/m³ (🟡)
• 06.11.2024: 25 µg/m³ (🟡)
• 14.12.2024: 24 µg/m³ (🟡)
• 13.11.2024: 22 µg/m³ (🟡)

In comparison, the cleanest air quality in Bottrop was measured on January 7, 2025 with only 3 µg/m³. The highest fine dust value in Düsseldorf was 31 µg/m³.

In addition, the Environmental Federal Agency has published information on fine dust pollution in Germany. Measurements for PM10 and since 2008 have been carried out for PM2.5. High measuring network densities in metropolitan areas are due to numerous issuers such as traffic and industry. Despite a reduction in the PM10 annual means of 50 µg/m³ in the 1990s, the current values ​​are between 15 and 20 µg/m³. This happened, taking weather -related fluctuations into account, which can lead to high concentrations in dry winters or hot summers.
