Air quality today

The air quality in Duisburg today is classified as Moderate. The primary pollutant identified is PM2.5, fine particulate matter measured at a reference value of 13.347 µg/m³. In addition, the corresponding PM10 level is recorded at 26.445 µg/m³ based on thirteen valid measurements.

What the data includes

The dataset for Duisburg contains measurements of six key air‑quality constituents – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). Across the city 16 individual rows of data have been collected from four monitoring stations, giving a modest spatial coverage that varies by pollutant.

The most recent values are all from early February 2026 except for NO, whose newest entry dates back to March 2024. PM₁₀, NO₂, SO₂, PM₂.₅ and O₃ each show a “last updated” timestamp of 2026‑02‑10 17:00 UTC, indicating that the bulk of the current snapshot is less than two weeks old. By contrast, the NO data are older by almost two years, which means recent nitrogen monoxide levels are not reflected in this release.

Across the available measurements the observed ranges are fairly narrow. PM₁₀ values span from about 8 µg/m³ to 26 µg/m³ with a median near 12 µg/m³; NO₂ stays between roughly 26 and 34 µg/m³, centering on 27 µg/m³; SO₂ is low, ranging from just over 1 to just above 3 µg/m³. PM₂.₅ varies from about 5 to 13 µg/m³ with a median of 9 µg/m³, while O₃ is represented by a single reading of 22.7 µg/m³. The NO data, however, cover a broader spread—from just over 3 up to nearly 20 µg/m³—with the highest recorded value at the Kardinal‑Galen‑Straße site.

Overall the dataset provides recent information for most pollutants but shows uneven temporal coverage, especially for nitrogen monoxide. Consequently, while the figures give a snapshot of current air quality in Duisburg, conditions can differ across neighbourhoods and may have changed since the last measurement at any given station.

Data notes

The data shown for Duisburg are based on 13 valid measurements and were refreshed recently, with the latest update recorded at 2026‑02‑10T17:00:00+00:00 (Updated within 3 days). This snapshot reflects conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
