Air quality today
The air quality in Gennevilliers today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements from three valid monitoring stations show a PM2.5 reference value of 3.9 and a PM10 reference value of 7.8. These figures are provided through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Gennevilliers air‑quality dataset contains four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). The data come from a single monitoring station that contributed seven rows of observations overall.
For NO2, PM10 and PM2.5 the most recent values were recorded on 2026‑02‑10 at 17:00 UTC, so these three pollutants have fresh readings that are less than three days old. Their minimum, median and maximum concentrations show a modest spread: NO2 ranged from 22.1 to 34.9 µg/m³ with a median of 28.5 µg/m³; PM10 varied between 7.8 and 34.7 µg/m³ with a median of 21.25 µg/m³; PM2.5 was observed from 3.9 to 11.9 µg/m³ with a median of 7.9 µg/m³. The 10th‑percentile values (23.38 µg/m³ for NO2, 10.49 µg/m³ for PM10 and 4.7 µg/m³ for PM2.5) indicate that most recent measurements tend to sit toward the lower end of each range, while the 90th‑percentile values (33.62, 32.01 and 11.1 respectively) capture the higher tail.
In contrast, NO has only a single recorded value – 6.5 µg/m³ – dated 2024‑03‑11 at 09:00 UTC, which is classified as old data. This older timestamp means that current conditions for NO are not represented in the latest snapshot, highlighting an uneven temporal coverage across pollutants. Overall, while three key pollutants have up‑to‑date information from a single site, the dataset’s breadth is limited to one location and includes an outdated entry for NO, so city‑wide air quality can still vary by place and time beyond what these rows capture.
