This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Talagante is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 29.0 µg/m³ and a PM10 level of 32.0 µg/m³, based on two valid observations.
Data are shown via OpenAQ. 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 Talagante air‑quality record consists of 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). The data set contains six rows, one for each pollutant, so coverage is limited to this lone site.
The most recent measurements are from 2026‑02‑10 13:00 UTC for PM10 (32.0 µg/m³) and PM2.5 (29.0 µg/m³), indicating that the particulate data have been updated within the last three days. All other pollutants show older timestamps: CO was last recorded on 2021‑05‑18 04:00 UTC with a value of 0.0 µg/m³, O3 on 2021‑05‑01 03:00 UTC also at 0.0 µg/m³, SO2 on the same day as CO (2021‑05‑18 04:00 UTC) at 0.0 µg/m³, and NO2 on 2019‑12‑05 17:00 UTC with a value of 134.8 µg/m³. Thus, while particulate matter data are fresh, the remaining gases are based on information that is several years old.
Across the six pollutants the recorded values show little variation because each metric has only one reported figure. The median and extreme values are identical for every pollutant: CO, O3 and SO2 all sit at 0.0 µg/m³; NO2 remains constant at 134.8 µg/m³; PM10 is fixed at 32.0 µg/m³; and PM2.5 at 29.0 µg/m³. This uniformity reflects the single‑row nature of the dataset rather than a range of observed conditions.
Because the station count is limited to one location and most gas‑phase measurements are dated, the available data provide only a snapshot of Talagante’s air quality at specific moments. Conditions can differ across neighborhoods and over time, so users should consider that the presented figures may not represent current or city‑wide levels for all pollutants.
