Air quality today

The air quality in Évreux today is classified as Good. The main pollutant identified is PM2.5, with a measured concentration of 2.5 µg/m³. A concurrent measurement for larger particles shows PM10 at 3.6 µg/m³, based on four valid observations collected through OpenAQ.

These values reflect the current monitoring snapshot for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Évreux pulls data from two monitoring sites that together provide eight recent observations across six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), fine particulate matter (PM₂.5), coarse particulate matter (PM₁₀) and sulphur dioxide (SO₂). The most up‑to‑date entries are from 2026‑02‑10 15:00 UTC for NO₂, O₃, PM₂.5, PM₁₀ and the older sensor still reports NO at 2024‑03‑11 09:00 UTC, while SO₂ is only available from a 2016‑12‑05 reading.

Across the recent data set, NO₂ shows a wide spread, ranging from a low of 2.5 µg/m³ to a high of 83.75 µg/m³ with a median around 43.13 µg/m³; PM₂.5 varies between 2.5 and 38.5 µg/m³, centred near 20.5 µg/m³. In contrast, the other pollutants are represented by single values: NO is consistently recorded at 8.5 µg/m³, O₃ at 69.5 µg/m³, PM₁₀ at 3.6 µg/m³ and SO₂ at 5.25 µg/m³.

The dataset highlights an uneven temporal coverage: four of the eight rows are fresh (updated within the last three days), while the remaining four are older, with one pollutant (SO₂) lacking any recent measurement for more than a decade. This mix means that while recent snapshots exist for most gases and particles, the picture is incomplete for sulphur dioxide and may not capture short‑term fluctuations across the city. Consequently, conditions in Évreux can differ by location and time, and the available data reflects both current and historical observations.
