Air quality today

The air quality in Airvault today is classified as Good. The primary pollutant identified is PM10, with a measured reference value of 10.5 micrograms per cubic metre based on four valid observations.

Data are shown via OpenAQ and reflect the current assessment for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Airvault’s OpenAQ feed currently provides data for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and sulphur dioxide (SO₂). The dataset contains nine measurement rows collected from two monitoring sites, all located at the “AIRVAULT - Stade Laillé” station. Freshness varies across the suite: the most recent NO₂, O₃ and SO₂ values were recorded on 2026‑02‑10 at 15:00 UTC, while PM₁₀ was last updated on 2026‑02‑09 at 03:00 UTC. The lone NO observation is considerably older, dated 2024‑03‑11 at 09:00 UTC, and therefore reflects historic conditions rather than the current air quality.

Across the recent measurements, concentrations show a modest spread. NO₂ values range from 2.1 to 14.8 µg/m³ with a median of about 8.5 µg/m³; O₃ spans 33.4‑52.6 µg/m³, centering around a median of 43 µg/m³; PM₁₀ varies between 10.5 and 29.2 µg/m³ with a typical value near 19.9 µg/m³; SO₂ is low, ranging from 0.5 to 0.9 µg/m³ and clustering around 0.7 µg/m³. The single NO reading sits at 0.4 µg/m³, matching its minimum, median and maximum because no newer data are available.

The coverage is uneven: four of the five pollutants have very recent observations (within three days), but PM₁₀’s latest entry is a week old and NO’s data are almost two years stale. Consequently, while the current snapshot gives a clear picture for most gases, the limited and outdated NO record means that any assessment of nitrogen monoxide in Airvault must acknowledge this gap. Overall, the dataset offers a concise but temporally mixed view of air quality across the city.
