Air quality today

The air quality in Fiumicino today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 7.0 and a PM10 reference value of 20.0, based on eleven valid observations collected via OpenAQ.

Overall conditions meet the criteria for a Good rating according to the latest assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Fiumicino currently includes seven measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). Data come from two monitoring stations, providing a total of eleven recent rows across all compounds.

All timestamps are fresh, with the most recent updates recorded between 2026‑02‑08 and 2026‑02‑09. The newest NO reading (0.0 µg/m³) was logged at Fiumicino Porto on 2026‑02‑09 00:00 UTC; NO₂ and SO₂ share a last update of 2026‑02‑09 03:00 UTC at the same site, while O₃ and PM₂.5 were most recently captured at Fiumicino Villa Guglielmi on 2026‑02‑09 03:00 UTC and 2026‑02‑08 00:00 UTC respectively. No entry is marked as unknown or older than seven days.

The observed values show a narrow spread for several pollutants. NO ranged from 0.0 to 1.0 µg/m³ with a median of 0.5, while NOX stayed tightly between 6.0 and 7.0 µg/m³ (median 6.5). PM₁₀ varied only from 18.0 to 20.0 µg/m³ (median 19), and SO₂ was constant at 2.2 µg/m³ across its single reading. In contrast, NO₂ displayed a broader interval, ranging from 5.0 up to 12.0 µg/m³ with a median of 8.5, indicating more variability at the Porto site. O₃ and PM₂.5 each have a single reported value (49.0 µg/m³ for ozone and 7.0 µg/m³ for fine particles), so their current picture is limited to those points.

Overall, the dataset offers recent coverage from two locations but is uneven across pollutants: some compounds are represented by multiple rows allowing assessment of range and median, while others rely on a single observation. Consequently, while the latest figures give an up‑to‑date snapshot for Fiumicino, spatial and temporal variation may still exist beyond what these limited rows capture.
