Air quality today
The air quality in Les Mazures is classified as Good today. The primary pollutant identified is PM2.5, fine particulate matter measured in the atmosphere.
Measurements show a PM2.5 concentration of 2.1 µg/m³ and a PM10 level of 3.1 µg/m³ based on four valid observations recorded by OpenAQ. 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 air‑quality record for Les Mazures draws on a single monitoring station, so each pollutant is represented by one row of data. The dataset includes measurements for nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and particulate matter ≤2.5 µm (PM₂.₅).
The most recent observations were all captured on 2026‑02‑10 at 15:00 UTC for NO₂, O₃, PM₁₀ and PM₂.₅, while the NO value dates back to 2024‑03‑11 at 08:00 UTC and is flagged as old data. This means that, apart from NO, the latest readings are less than three days old, providing a fairly fresh snapshot of current conditions for four of the five pollutants.
Across the five substances the recorded values show virtually no variation: each pollutant’s minimum, median, 10th percentile, 90th percentile and maximum are identical. NO registers at 0.0 µg/m³, NO₂ at 1.8 µg/m³, O₃ at 72.6 µg/m³, PM₁₀ at 3.1 µg/m³ and PM₂.₅ at 2.1 µg/m³. Because there is only one row per pollutant, the dataset cannot reveal any spread or trends over time; it simply reflects a single point measurement for each component.
Consequently, while the data set offers up‑to‑date information for most pollutants, its coverage is limited to one location and lacks historical depth. Users should keep in mind that air quality can differ across neighborhoods and throughout the day, and the single‑station snapshot may not capture those spatial or temporal variations.

Data notes
The dataset for Les Mazures contains four valid measurements and is updated within three days, with the most recent data recorded on 2026‑02‑10 at 15:00 UTC. This information reflects a single point in time; air quality can differ across neighbourhoods and fluctuate throughout the day, so values shown may not represent conditions elsewhere in the city or later periods.
