Air quality today

The air quality in Le Petit‑Quevilly is classified as Good today. The primary pollutant measured is PM2.5, fine particulate matter that is being monitored alongside other indicators.

Five valid measurements were recorded, showing a PM2.5 reference value of 3.5 and a PM10 reference value of 5.0. These figures reflect the current monitoring results provided via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Le Petit‑Quevilly’s OpenAQ feed contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). The data come from three monitoring stations that together provide nine individual rows of observations.

The most recent measurements are all from 2026‑02‑10 at 17:00 UTC for NO₂, PM₁₀ and PM₂.₅, giving a median NO₂ concentration of 18 µg/m³ (range 7.4–43.9 µg/m³), a median PM₁₀ of 5 µg/m³ (range 1.8–20.8 µg/m³) and a single‑value PM₂.₅ reading of 3.5 µg/m³. These three pollutants therefore have fresh data updated within the last three days. In contrast, SO₂ is only available from an older record dated 2020‑12‑30 at 10:00 UTC, with a constant value of 0.7 µg/m³, and NO comes from a single entry on 2024‑03‑11 at 09:00 UTC showing 25.5 µg/m³. Thus, coverage is uneven: half of the pollutants are represented by recent multi‑day series, while the other half rely on isolated or dated points.

Overall, the dataset shows a modest spread for the newer pollutants – the 10th percentile values sit near the lower end (NO₂ ≈ 9.5 µg/m³, PM₁₀ ≈ 2.4 µg/m³) and the 90th percentiles approach the upper extremes (NO₂ ≈ 38.7 µg/m³, PM₁₀ ≈ 17.6 µg/m³). The limited number of stations (three) means that spatial variation across Le Petit‑Quevilly is not fully captured, especially for NO and SO₂ where only a single historic reading exists. Consequently, while recent data give a snapshot of current conditions for some pollutants, the overall picture remains partial and can differ by location and time within the city.

Data notes

The data shown for Le Petit‑Quevilly is based on five valid measurements and was refreshed recently, having been updated within three days (last update: 2026‑02‑10T17:00:00+00:00). While this snapshot provides a reliable overview of current conditions, air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in these figures.
