Air quality today

The air quality in Puertollano, Castile-La Mancha, is currently classified as Hazardous. The primary pollutant identified is PM2.5 (fine particles). Recent observations report a PM2.5 concentration of 726.0 µg/m³ and a PM10 concentration of 7.0 µg/m³. These figures are based on 19 valid measurements collected during the latest monitoring period. All reported concentrations are expressed in micrograms per cubic meter. A total of 19 valid data points contributed to the current assessment. The reported values place the overall assessment in the Hazardous category.

The data are shown via OpenAQ and reflect the most recent set of readings for the city. OpenAQ aggregates measurements from local monitoring stations to provide a consolidated view. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Puertollano in Castile‑La Mancha contains data from six monitoring sites, contributing a total of thirty‑four rows. Nineteen of those rows have been updated within the last thirty days, while the remaining fifteen are older than a month, so the overall picture mixes recent and dated observations. All seven regulated pollutants are represented: carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), sulphur dioxide (SO₂), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅).

The most recent NO₂ value is 2.0 µg/m³ recorded at the Campo de Fútbol sensor on 2026‑02‑09 15:00 UTC, with the dataset ranging from 2.0 to 40.0 µg/m³ and a median of 3.5 µg/m³. Ozone shows a broader spread, from 3.0 µg/m³ up to 76.0 µg/m³, median 37.5 µg/m³, and the latest reading of 76.0 µg/m³ also comes from Campo de Fútbol on 2026‑02‑09 15:00 UTC. SO₂ is confined to low levels, 2.0 µg/m³ minimum and 12.0 µg/m³ maximum, median 2.0 µg/m³, with the newest measurement of 2.0 µg/m³ at the same site on 2026‑02‑09 15:00 UTC. NO is recorded only up to 3.0 µg/m³, median 2.5 µg/m³, and its latest entry dates back to 2024‑02‑13 00:00 UTC. PM₁₀ values are modest, ranging from 4.0 to 7.0 µg/m³, median 5.5 µg/m³, with the freshest record of 4.0 µg/m³ on 2026‑02‑09 12:00 UTC. PM₂.₅ displays the greatest variability, from 12.0 µg/m³ to a high of 726.0 µg/m³, median 351.0 µg/m³, and the most recent measurement of 726.0 µg/m³ was logged at Almacén Municipal on 2026‑01‑29 04:00 UTC. CO is represented by a single value of 3500.0 µg/m³ from Campo de Fútbol, last updated on 2026‑01‑01 21:00 UTC. These figures illustrate that while some pollutants have frequent, recent sampling, others rely on older data, and the concentration ranges differ markedly across the measured species.
