Air quality today

The air quality in Arteixo today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 1.8 and a PM10 reference value of 6.3, based on 23 valid observations collected via OpenAQ.

Overall conditions meet the criteria for the Good category according to the latest assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Arteixo’s air‑quality feed draws from four monitoring sites that together contribute 28 recent observations across the seven key pollutants tracked in Spain – carbon monoxide (CO), nitrogen oxides (NO and NO₂), ozone (O₃), particulate matter of both 10 µm and 2.5 µm size (PM10, PM2.5) and sulphur dioxide (SO₂). The data set is unevenly populated: CO, O₃, NO₂, SO₂, PM10 and PM2.5 each have at least three recent rows recorded within the last week, while nitrogen monoxide (NO) is represented by only four rows that date back to 2024‑03‑01, making it the oldest entry in the collection.

Across the pollutants with fresh measurements, the observed values span a modest range. The highest reported concentration is CO at 280 µg/m³ from the PAIOSACO site (2026‑02‑09 10:00 UTC), while the lowest minima sit at 1 µg/m³ for both NO and SO₂ at the PASTORIZA‑REPSOL station (2026‑02‑09 15:00 UTC). Median levels are similarly low: NO₂ averages 4 µg/m³, SO₂ 1.4 µg/m³, PM10 about 3.7 µg/m³ and PM2.5 1.35 µg/m³, indicating that most recent readings cluster near the lower end of each pollutant’s observed spread. Ozone shows a tighter band, with values ranging from 59 to 68 µg/m³ and a median of 60 µg/m³ at CENTRO CIVICO (2026‑02‑09 15:00 UTC).

Because the dataset contains only a handful of recent rows for some gases – notably NO – and no entries classified as “unknown”, the picture of Arteixo’s air quality is necessarily limited to the locations and times captured by these sensors. Conditions can differ across neighbourhoods and over shorter intervals than those reflected here, so the figures represent a snapshot rather than a comprehensive, city‑wide assessment.
