What the data includes

The City of Zenica air‑quality feed contains six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). Data come from eight monitoring rows spread across four stations, but the number of recent observations varies by pollutant. The most up‑to‑date readings were recorded on 2026‑02‑10 at 21:00 UTC for every pollutant, so the freshest timestamp in the set is just a few days old.

Across the city the observed values show a wide spread. Ozone measured 8.81 µg/m³ at the central station, while its minimum and maximum across all rows range from about 1.86 to 110.07 µg/m³, with a median of 8.41 µg/m³. PM10 values are centred around a median of 70 µg/m³ but range from 24.5 up to 101 µg/m³, indicating considerable variability between sites such as Brist (38.06 µg/m³) and other locations. Sulfur dioxide shows a median of 32.44 µg/m³ with extremes from 1.45 to 113 µg/m³, and the central station reported 29.59 µg/m³ on the latest update. Nitrogen dioxide’s median sits at 35 µg/m³, spanning 4.79‑54.67 µg/m³; the most recent reading was 43.03 µg/m³ at the same central site.

Carbon monoxide displays the highest absolute numbers, with a median of 1 410 µg/m³ and a range from 133 to 2 449 µg/m³; the latest central‑station value was 1 495.52 µg/m³. PM2.5 is represented by only one recent row from Vranduk, giving a single value of 22.45 µg/m³ and no observed spread. Overall, while most pollutants have several recent observations, PM2.5 coverage is limited to a single measurement, and the distribution of rows shows that some substances are monitored more extensively than others, meaning city‑wide conditions can differ by location and time.
