Air quality today

The air quality in Villefranche‑sur‑Saône is classified as Good today. The primary pollutant measured is PM2.5 (fine particles). OpenAQ data show a PM2.5 value of 3.1 µg/m³ and a concurrent PM10 measurement of 5.8 µg/m³, based on four valid observations.

These figures reflect the current monitoring snapshot for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality dataset for Villefrange‑sur‑Saône draws from two monitoring stations, each providing a single row of recent observations. Five pollutants are represented: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). The most up‑to‑date measurements were recorded on 2026‑02‑10 at 15:00 UTC for NO₂, O₃, PM10 and PM2.5, while the NO reading dates back to 2024‑03‑11 at 09:00 UTC, making it the only older entry in the set.

Across the recent data the observed concentrations span modest ranges. NO₂ varies from a low of 19.7 µg/m³ to a high of 24.3 µg/m³, with a median near 22.0 µg/m³; O₃ shows a broader spread, from 14.1 µg/m³ up to 52.4 µg/m³ and a median of 33.2 µg/m³. PM10 values sit between 5.8 and 20.3 µg/m³ (median 13.1), while PM2.5 ranges from 3.1 to 11.8 µg/m³ (median 7.45). The single NO measurement is fixed at 19.1 µg/m³, reflecting the limited recent coverage for this pollutant.

Because only two rows are available, the dataset provides a snapshot rather than a continuous picture of city‑wide air quality. Most pollutants have fresh readings within the last three days, but the older NO value highlights an uneven temporal coverage that could miss short‑term fluctuations. Consequently, while the current figures give a clear sense of typical concentrations at the Villefranche Centre site, conditions elsewhere in the city or at other times may differ.

Data notes

The current dataset for Villefranche‑sur‑Saône includes four valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10 15:00 UTC. These figures represent a snapshot of conditions captured by the monitoring network; air quality can differ across neighborhoods and change throughout the day, so local values may vary from those shown here.
