What the data includes

The Mechelen air‑quality record draws on data from two monitoring sites that together provide twelve rows of observations across four key pollutants – nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and fine particulate matter 2.5 µm or less (PM2.5). All the latest readings were recorded on 2026‑02‑10 at 17:00 UTC, so the dataset reflects conditions that are fresh within the past three days for each pollutant.

For NO2 the values range from a low of 21.0 µg/m³ to a high of 44.5 µg/m³, with a median also at 21.0 µg/m³ and the 90th percentile reaching 39.8 µg/m³. Ozone shows a much broader spread: the minimum recorded is 3.0 µg/m³ while the maximum hits 52.0 µg/m³, the same figure that appears as the median and 90th percentile, indicating that higher ozone levels dominate the recent measurements. PM10 values are clustered toward the lower end of the scale, from 7.8 to 30.7 µg/m³, with a median of 7.8 µg/m³ and the 90th percentile at 26.12 µg/m³. Fine particles (PM2.5) display the narrowest range, spanning 3.454 to 24.5 µg/m³; the median matches the minimum at 3.454 µg/m³ and the 90th percentile sits at about 20.29 µg/m³.

Overall the dataset offers a fairly complete snapshot for each pollutant, but the distribution is uneven: ozone readings reach much higher levels than the other three substances, while PM2.5 remains consistently low in the recent sample. Because the data come from only two stations, conditions can still vary across different neighbourhoods of Mechelen, and occasional older rows (four out of twelve) mean that not every measurement reflects the most current state.

Data notes

The data set for Mechelen includes eight valid measurements and is updated within three days, with the latest refresh recorded at 2026‑02‑10T17:00:00+00:00. These figures represent a recent snapshot of ambient conditions across the city; however, air quality can differ by specific neighbourhoods and change throughout the day, so local variations may not be fully captured in this summary.
