Air quality today

The air quality in Uijeongbu‑si is currently classified as Unhealthy. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 59.0 µg/m³ and a PM10 level of 73.0 µg/m³, based on 18 valid observations collected through OpenAQ.

These values reflect the present conditions reported for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Uijeongbu‑si’s OpenAQ feed currently provides data for six common air pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10), particulate matter 2.5 µm or smaller (PM2.5) and sulfur dioxide (SO₂). The dataset contains 18 individual rows drawn from three monitoring stations, all of which report the same most‑recent measurement time of 2026‑02‑10 17:00 UTC, so the information is fresh within the last seven days for every pollutant.

The recorded values show a relatively narrow spread for each gas. CO ranges from 0.66 to 0.80 ppm with a median of 0.69 ppm; NO₂ varies between 0.0337 and 0.0392 ppm, centering on 0.035 ppm; O₃ is low throughout the period, from 0.001 to 0.0019 ppm with a typical value of 0.0014 ppm. Particulate matter shows higher absolute numbers: PM10 values sit between 58 and 73 µg/m³ (median 60 µg/m³) while PM2.5 spans 35 to 59 µg/m³, medianing at 52 µg/m³. SO₂ is the least variable, recorded from 0.0028 to 0.0031 ppm with a median of 0.003 ppm.

Because all rows share the same recent timestamp, there are no older or unknown entries in this snapshot, indicating consistent reporting across the three stations. However, the dataset’s breadth is limited to these three locations, so conditions can differ in other parts of Uijeongbu‑si that are not directly captured here. The pollutant measurements themselves exhibit modest variability, with particulate matter showing the widest range and the gases remaining tightly clustered around their median values.
