Air quality today
The air quality in Puzi City is classified as USG. The primary pollutant identified today is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 37.0 µg/m³ and a PM10 level of 67.0 µg/m³, based on six valid observations reported through OpenAQ.
These values reflect the current monitoring snapshot for Puzi City. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Puzi City currently draws from two monitoring stations that together provide twelve recent observations across six key 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 were recorded at the same moment – 2026‑02‑10 23:00 UTC – and are flagged as “Updated within 7 days,” indicating that the newest data for every pollutant is less than a week old.
Across the two stations the measured concentrations show a modest spread. CO ranges from 0.19 to 0.44 ppm with a median of 0.315 ppm; NO₂ varies between 0.0003 and 0.017 ppm, centred around 0.0087 ppm; O₃ is observed from 0.006 up to 0.0301 ppm, with a typical value near 0.018 ppm. For the particulate fractions, PM10 values sit between 25 and 67 µg/m³ (median 46 µg/m³) while PM2.5 spans 10 to 37 µg/m³ (median 23.5 µg/m³). SO₂ is recorded from 0.0005 to 0.0018 ppm, with a median of 0.00115 ppm.
Because the data come from only two sites, spatial coverage within Puzi City is limited; conditions can differ in neighborhoods that are not directly represented by these stations. Nevertheless, the recent timestamps mean the figures reflect the city’s air quality at a single point in time rather than an outdated picture. Users should keep in mind that variations throughout the day or across unmonitored areas may not be captured in this snapshot.

Data notes
The current dataset for Puzi City is based on six valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T23:00:00+00:00 (updated within 3 days). This snapshot reflects conditions captured across the monitoring network at that time. Keep in mind that air quality can differ by specific location and moment within the city, so values may vary locally.
