Air quality today

The air quality in Villa María del Triunfo is currently classified as Moderate. The primary pollutant identified is PM2.5, fine particulate matter that is being measured alongside PM10. Recent data show a PM2.5 reference value of 13.9 µg/m³ and a PM10 reference value of 36.13 µg/m³, based on five valid measurements collected through OpenAQ.

These figures reflect the present monitoring conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Villa María del Triunfo contains a single monitoring station that reports six pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). In total there are six rows of data, one for each measured compound.

The CO measurement is the only value that dates back to 2017‑07‑20 06:00 UTC, so it reflects conditions from more than eight years ago and is flagged as “old data.” All other pollutants have been updated very recently, with their latest timestamps recorded on 2026‑02‑10 16:00 UTC, which places them in the “updated within 7 days” freshness category. Because each pollutant shows a single reported figure—minimum, median and maximum are identical—the dataset does not capture variability over time; it provides only a snapshot for each compound.

Specifically, the most recent values are 1.0 ppm for CO, 28.24 µg/m³ for NO₂, 33.26 µg/m³ for O₃, 36.13 µg/m³ for PM10, 13.9 µg/m³ for PM2.5 and 12.39 µg/m³ for SO₂. The uniformity of these numbers indicates that the station has recorded one measurement per pollutant rather than a range of observations. Consequently, while the data set offers coverage of all six key air‑quality indicators, the limited number of stations and the age of the CO reading mean that the picture it provides is static and may not reflect current conditions across different neighborhoods or times of day in Villa María del Triunfo.
