Air quality today

The air quality in Fos‑sur‑Mer today is classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 8.8 µg/m³ based on three valid observations from OpenAQ data.

No other pollutants reached reporting thresholds, and the available measurements indicate that conditions remain within the Good category for this location. 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 Fos‑sur‑Mer includes measurements of nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). Across the city there are nine data rows originating from four monitoring stations, but the timing of those records varies widely. Only three of the rows were updated within the past week – two for SO₂ (last refreshed on 2026‑02‑10 15:00 UTC) and one for PM₂.₅ (last refreshed on 2026‑02‑09 03:00 UTC). All other entries are older than a year, with NO₂ recorded in December 2019, O₃ in December 2017 and PM₁₀ in January 2020.

The values that are currently available show modest ranges. SO₂ concentrations range from 0.1 to 1.1 µg/m³, with a median of 0.8 µg/m³; the most recent reading is 0.7 µg/m³ at the Fos sur Mer site. PM₂.₅ spans 8.8 to 10.2 µg/m³, median 9.5 µg/m³, and the latest measurement is 8.8 µg/m³ from the Fos Les Carabins location. NO₂ is reported as a single value of 16.4 µg/m³ (FR02013), O₃ likewise as one value of 35.75 µg/m³ (FR02013), and PM₁₀ appears only once at 20.5 µg/m³ (FR02013). The spread for the newer pollutants (SO₂, PM₂.5) is relatively narrow, while the older data provide just single points without any indication of variability.

Overall, the dataset offers a snapshot of five key pollutants but is unevenly populated: recent information exists for only two substances and covers just one station each, whereas the remaining three pollutants rely on dated single‑station records. Consequently, while the available numbers give a basic picture of current concentrations, they do not capture temporal changes or spatial differences across Fos‑sur‑Mer, and conditions can differ by location and time beyond what is reflected in these limited entries.

Data notes

The current dataset for Fos‑sur‑Mer includes three valid measurements and is marked as Updated within 3 days, with the latest values recorded at 2026‑02‑10T15:00:00+00:00. These figures represent a snapshot of ambient conditions captured by the monitoring network; air quality can differ across neighborhoods and change throughout the day, so local variations may not be reflected in this summary.
