Air quality today
The air quality in Seongju‑eup is currently classified as Moderate. The primary pollutant identified is PM2.5, fine particulate matter, with a measured concentration of 24.0 µg/m³. In addition, the level of larger particles (PM10) has been recorded at 25.0 µg/m³ based on six valid observations from OpenAQ data.
These figures reflect the present monitoring results for the area and are provided without interpretation or recommendation. 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 Seongju‑eup contains a single monitoring row, so each pollutant is represented by one recent measurement taken at the same location in 성주군 on 2026‑02‑10 18:00 UTC. All six common air‑quality species are available: carbon monoxide (CO) at 0.57 ppm, nitrogen dioxide (NO2) at 0.0285 ppm, ozone (O3) at 0.0052 ppm, particulate matter ≤10 µm (PM10) at 25.0 µg/m³, particulate matter ≤2.5 µg/m³ (PM2.5) at 24.0 µg/m³, and sulfur dioxide (SO2) at 0.0021 ppm. Because there is only one row, the minimum, median, maximum, 10th‑percentile and 90th‑percentile values are identical for each pollutant, indicating no observed spread in the data.
The freshness of the record is uniform: every parameter was last updated within the past seven days, satisfying the “Updated within 7 days” flag. This means the snapshot reflects conditions on a single day rather than a longer trend, and any variation that occurs at other times or locations in Seongju‑eup will not be captured here.
With just one monitoring point, coverage across the city is limited; spatial differences in pollutant concentrations cannot be assessed from this dataset. Nonetheless, the available numbers give a clear picture of the measured levels at the reporting site on 2026‑02‑10, and they serve as the sole quantitative reference for air quality in Seongju‑eup until additional stations or more frequent updates are added.
