Air quality today

The air quality in Saint‑Germain‑sur‑Rhône is classified as Good today. The primary pollutant identified is PM2.5, fine particulate matter measured by the monitoring network.

Five valid measurements were recorded, showing a PM2.5 reference value of 2.5 µg/m³ and a PM10 reference value of 3.8 µg/m³. Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Saint‑Germain‑sur‑Rhône dataset contains a single monitoring row that reports six common air‑quality 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 values are expressed in micrograms per cubic metre.

The most recent measurement for NO dates back to 2024‑03‑11 09:00 UTC, while the other five pollutants were last updated on 2026‑02‑10 15:00 UTC, meaning that half of the data is less than three days old and the remaining half is just over two years old. Because there is only one row, the dataset does not provide any range or variability for each pollutant; the minimum, median and maximum are identical for every substance. For example, NO registers a single value of 3.2 µg/m³, NO2 shows 3.7 µg/m³, O3 records 59.5 µg/m³, PM10 is 3.8 µg/m³, PM2.5 is 2.5 µg/m³ and SO2 reads 0.0 µg/m³.

With just one monitoring location, the coverage for Saint‑Germain‑sur‑Rhône is limited, so the reported figures represent conditions at that specific site rather than a city‑wide picture. The dataset includes recent data for most pollutants but still relies on an older NO reading, highlighting uneven freshness across the measured species. Users should keep in mind that air quality can differ across neighborhoods and times of day, and the single‑row snapshot may not capture those variations.

Data notes

The data shown for Saint‑Germain‑sur‑Rhône are based on five valid measurements and were updated within three days, with the latest refresh recorded at 2026‑02‑10T15:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent the entire city at any given moment.
