Air quality today

The air quality in Bassens today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 2.6 and a PM10 reference value of 3.7, based on five valid observations recorded by OpenAQ.

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

What the data includes

The Bassens monitoring network supplies data for six pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All measurements come from two active stations, giving a total of twelve pollutant‑row entries in the dataset.

The most recent observations are fairly current for most gases: NO₂, O₃, PM₁₀, PM₂.₅ and SO₂ were all recorded on 2026-02-10 (or 2026-02-09 for SO₂) between 15:00 UTC and 23:00 UTC, meaning the newest values are less than a day old. NO is an exception; its latest reading dates back to 2024-03-11 09:00 UTC, so it is older by almost two years.

Across the six pollutants the recorded concentrations span modest ranges. NO varies from a low of 3.3 µg/m³ up to 5.0 µg/m³, with a median around 4.2 µg/m³. NO₂ shows a broader spread, ranging from 4.0 to 37.5 µg/m³ and a median near 20.8 µg/m³. Ozone values sit between 25.1 and 53.9 µg/m³ (median ≈ 39.5 µg/m³). Fine particles are low, with PM₂.₅ from 2.6 to 5.1 µg/m³ (median ≈ 3.85 µg/m³) and PM₁₀ from 3.7 to 7.5 µg/m³ (median ≈ 5.6 µg/m³). Sulfur dioxide is the smallest measured quantity, ranging only from 0.2 to 0.4 µg/m³ (median ≈ 0.30 µg/m³).

Because the dataset contains just two stations, spatial coverage across Bassens is limited; conditions can differ in neighborhoods not directly sampled. The overall picture is one of recent data for most pollutants but a notable gap for NO, highlighting that some aspects of air quality may be less up‑to‑date than others.
