Air quality today

The air quality in the Municipal Unit of Elefsina is classified as Good today. The primary pollutant measured is PM2.5 (fine particles). Five valid measurements were recorded, showing a PM2.5 concentration of 7.0 µg/m³ and a PM10 level of 21.0 µg/m³.

Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Elefsina monitoring dataset contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). All values come from a single reporting row, so the station coverage for this city is limited to one sensor location.

The most recent observations are fairly current for five of the pollutants, with the last update recorded on 2026-02-10 19:00 UTC. Only NO data are older, dated 2024-03-08 13:00 UTC, and are flagged as “Old data”. Across the dataset each pollutant shows a single reported figure, so the minimum, median and maximum values are identical. The recorded concentrations are 2.0 µg/m³ for NO, 27.0 µg/m³ for NO₂, 38.0 µg/m³ for O₃, 21.0 µg/m³ for PM₁₀, 7.0 µg/m³ for PM₂.5 and 4.0 µg/m³ for SO₂.

Because the data set consists of only one row per pollutant, there is no spread or variability to describe – each metric has a single point value rather than a range. The freshness of most measurements (within three days) suggests that recent conditions are captured for NO₂, O₃, PM₁₀, PM₂.5 and SO₂, while the older NO reading indicates a gap in up‑to‑date information for that specific gas. Users should keep in mind that air quality can differ across Elefsina, and the limited spatial coverage means these figures represent conditions at one monitoring site rather than the entire municipal unit.
