Air quality today
The air quality in Pudahuel is currently classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 13.0 µg/m³ and a PM10 level of 40.0 µg/m³, based on two valid observations recorded by OpenAQ.
These values reflect the present monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Pudahuel includes measurements of six common air‑quality 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). All values are expressed in micrograms per cubic metre (µg/m³). The source consists of six individual rows, each representing a single accredited monitoring station that reports one pollutant at a time.
The most recent observations come from the PM10 and PM2.5 sensors, both updated on 2026‑02‑10 13:00 UTC, showing concentrations of exactly 40.0 µg/m³ for PM10 and 13.0 µg/m³ for PM2.5. In contrast, CO, NO₂ and O₃ all share the same last update timestamp of 2021‑08‑20 21:00 UTC, with values fixed at 906.57 µg/m³, 87.42 µg/m³ and 1.1 µg/m³ respectively. The SO₂ measurement is the oldest, recorded on 2017‑06‑28 16:00 UTC and reporting a value of 0.0 µg/m³. Because each pollutant has only one recorded value, the minimum, median and maximum are identical for every metric, indicating that the dataset captures a single snapshot rather than a range of observations.
Overall, the coverage is uneven: half of the pollutants (PM10 and PM2.5) have very recent data, while the other four rely on information that is several years old. This mix of fresh and outdated timestamps means the current air‑quality picture for Pudahuel may not reflect short‑term variations across the city, and conditions can differ by location and time beyond what these six rows convey.
