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.
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 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.
