Air quality today
The air quality in Seraing today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements from three monitoring stations show a PM2.5 reference value of 2.55 and a PM10 reference value of 1.271, reflecting the current concentrations recorded for these particulate sizes.
Data are shown via OpenAQ and represent the latest available readings for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Seraing contains a single monitoring row, so all reported values come from one sensor located at “43R223 - JEMEPPE”. Five pollutants are represented: carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulphur dioxide (SO₂). Because there is only one station, the coverage across the city is limited to that specific site.
The most recent measurements are fairly fresh for four of the pollutants: CO was last recorded on 2026-01-14 08:00 UTC, while NO2, PM10 and PM2.5 all have updates from 2026-02-10 18:00 UTC, which falls within the past three days. SO₂ is older, with its latest value dated 2026-01-02 15:00 UTC and flagged as “old data”. All five pollutants show a single observed value, so the minimum, median, maximum, 10th‑percentile and 90th‑percentile are identical for each – CO at 220.0 µg/m³, NO2 at 22.0 µg/m³, PM10 at 1.271 µg/m³, PM2.5 at 2.55 µg/m³ and SO₂ at 1.0 µg/m³.
Because the data set consists of only one row, there is no spread or variability to describe; each pollutant’s range collapses to a single point. The freshness of most readings (within three days) suggests recent conditions are captured for CO, NO2 and the particulates, but the older SO₂ value indicates that information on sulphur dioxide may be less current. Users should keep in mind that air quality can differ across neighborhoods and times, and the single‑station snapshot does not reflect city‑wide variations.

Data notes
The data shown for Seraing reflects three valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10T18:00:00+00:00. These figures provide a recent snapshot of ambient conditions, but air quality can vary across different neighbourhoods and times of day within the city, so local levels may differ from those reported here.
