Air quality today

The air quality in Perafort today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 3.0 and a PM10 reference value of 3.0, based on six valid observations collected via OpenAQ.

Overall conditions meet the criteria for the Good category, reflecting low concentrations of the measured pollutants. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Perafort air‑quality dataset currently contains six pollutant measurements collected from a single monitoring location (PERAFORT (PUIGDELFÍ)). The available pollutants are nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All six rows were last updated on 2026‑02‑10 at 03:00 UTC, which falls within the “updated within 7 days” freshness bucket, so the data reflect very recent conditions for this site.

Each pollutant shows a single reported value that is identical across its minimum, median and maximum statistics, indicating no observed variation in the sampled period. NO registers 1.0 µg/m³, NO₂ and NOX both register 4.0 µg/m³, PM₁₀ and PM₂.5 each register 3.0 µg/m³, and SO₂ also registers 1.0 µg/m³. Because the dataset consists of only one station, these figures represent point measurements rather than city‑wide averages; conditions elsewhere in Perafort may differ.

The coverage is therefore limited to a single monitoring row for each pollutant, but the information is current and uniformly reported. With no spread between minimum and maximum values, the data set does not reveal temporal fluctuations at this location during the reporting window. Users should keep in mind that while the numbers are up‑to‑date, they capture only one spot in Perafort, so broader spatial patterns are not represented here.
