Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Zlatna contains measurements for five pollutants – carbon monoxide, nitrogen dioxide, ozone, particulate matter 10 and sulphur dioxide – drawn from six recorded rows that originate at two monitoring stations. The most recent data points are fairly fresh for nitrogen dioxide and PM10, both updated on 2026‑02‑10 19:00 UTC, while the other three pollutants rely on older entries: ozone was last logged on 2022‑04‑28 06:00 UTC, carbon monoxide on 2025‑11‑15 08:00 UTC and sulphur dioxide on the same 2025‑11‑15 timestamp.
Across the six rows, nitrogen dioxide shows a clear spread, ranging from a low of about 2 µg/m³ to a high of 27.14 µg/m³, with a median near 14.57 µg/m³ and the 10th–90th percentile band between roughly 4.5 and 24.6 µg/m³. In contrast, ozone is represented by a single value of 64.13 µg/m³, and PM10 also appears as a single measurement at 56.26 µg/m³. The carbon monoxide and sulphur dioxide entries are anomalous, both reporting negative values (‑1000 µg/m³ for CO and ‑1 µg/m³ for SO₂), which suggests sensor or data‑entry issues rather than realistic concentrations.
Overall the coverage is uneven: half of the pollutants have only one recent observation each, while nitrogen dioxide benefits from multiple rows that capture variability over time. The predominance of older timestamps for three of the five substances means that the snapshot may not reflect current conditions throughout Zlatna, and local air quality can differ by location and moment.
