The air quality in Puteaux today is classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 1.8 µg/m³ based on two valid observations from OpenAQ.
No other pollutants reached measurable levels for reporting. 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 Puteaux draws on four pollutant measurements – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). All data come from a single monitoring location identified as “LA DEFENSE”, so the dataset consists of one row per pollutant, giving a total of four rows.
The most recent observations are mixed in age. The NO reading is dated 2024‑03‑11 07:00 UTC and is flagged as old data, while the NO₂ and PM₂.₅ values were last updated on 2026‑02‑10 15:00 UTC, both marked as refreshed within three days. The PM₁₀ figure is considerably older, recorded on 2020‑12‑31 13:00 UTC and also classified as old data. Consequently, the freshest timestamps in the set are from early February 2026, but half of the pollutants rely on measurements that are several years out of date.
Across the four pollutants the reported concentrations are identical to their minimum, median and maximum values, indicating a single measurement per pollutant rather than a range of observations. NO registers 4.9 µg/m³, NO₂ shows 13.8 µg/m³, PM₁₀ is 8.4 µg/m³ and PM₂.₅ records 1.8 µg/m³. Because each pollutant has only one data point, there is no spread to describe variability; the dataset therefore provides a snapshot rather than a statistical profile.
In summary, Puteaux’s public air‑quality page offers four pollutants from one monitoring site, with two of them updated very recently and two relying on older measurements. Users should keep in mind that conditions can differ across neighborhoods and over time, and the limited temporal coverage means the figures represent specific moments rather than ongoing trends.
