What the data includes

The air‑quality record for Zwentendorf an der Donau currently contains data from nine measurement rows collected at three monitoring stations. All four key pollutants tracked by OpenAQ are represented: nitrogen dioxide (NO2), sulphur dioxide (SO2), particulate matter 10 µm or less (PM10) and fine particulate matter 2.5 µm or less (PM2.5). For NO2, PM10 and PM2.5 the most recent observations were uploaded on 2026‑02‑10 at 20:00 UTC, while the SO2 reading dates back to 2017‑07‑20 at 19:00 UTC, indicating that the sulphur dioxide data are considerably older than the other three pollutants.

Across the recent dataset, NO2 values range from about 7.7 µg/m³ up to 13.2 µg/m³, with a median of 12 µg/m³ and the central 80 % of measurements falling between roughly 8.6 and 13.0 µg/m³. PM10 shows a broader spread, from 11 µg/m³ to 28.5 µg/m³, a median of 19.75 µg/m³ and an inter‑percentile range of 12.8–26.8 µg/m³. Fine particles (PM2.5) vary between 7.15 µg/m³ and 23.5 µg/m³, median 15.3 µg/m³, with the middle 80 % lying from about 8.8 to 21.9 µg/m³. The single SO2 entry is a constant 2 µg/m³.

Because only three stations contribute data, spatial coverage within the municipality is limited and conditions can differ across neighborhoods. Moreover, while most pollutants have fresh measurements from early February 2026, the sulphur dioxide record is outdated by almost nine years, so current SO2 levels cannot be inferred from this source. Users should keep in mind that the available figures reflect a snapshot rather than continuous monitoring across all parts of Zwentendorf.
