What the data includes

The current station data listed for this city is focused on particulate matter (PM). In Los Ángeles, Biobio Region, the OpenAQ feed provides measurements for two pollutants – PM10 and PM2.5 – across four recent rows that come from two monitoring stations. Both pollutants have their most recent readings timestamped at 2026-02-10 13:00 UTC, indicating that the latest data are less than three days old.

PM10 values range from a low of 24 µg/m³ to a high of 27 µg/m³, with a median of 25.5 µg/m³ and the central 80 % of observations falling between roughly 24.3 and 26.7 µg/m³. PM2.5 shows a tighter spread, from 12 µg/m³ up to 13 µg/m³, median 12.5 µg/m³, with the 10th to 90th percentile bracket of about 12.1 to 12.9 µg/m³. The dataset therefore offers a fairly recent snapshot but is limited to two sites and only these two particulate metrics, so conditions may differ in other parts of the city or at later times.
