Air quality today
The air quality in Uljin‑eup is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 18.0 µg/m³ and a PM10 level of 24.0 µg/m³, based on six valid observations recorded by OpenAQ.
These values reflect the present conditions without implying any trend or cause. 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 air‑quality feed for Uljin‑eup includes six measured 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). All of these values come from a single monitoring location, so the dataset represents one row per pollutant rather than a network of stations across the city.
Each pollutant has a single recent reading that was last updated on 2026‑02‑10 at 17:00 UTC, which falls within the “updated within 7 days” freshness bucket. Because there is only one observation per metric, the reported minimum, median and maximum are identical for every substance. CO registers at 0.29 ppm, NO₂ at 0.0083 ppm, O₃ at 0.0327 ppm, PM₁₀ at 24.0 µg/m³, PM₂.₅ at 18.0 µg/m³ and SO₂ at 0.0019 ppm. The lack of variation means the dataset cannot show any spread or trend for these pollutants in Uljin‑eup.
With just one monitoring point, the coverage is limited to the conditions measured at that specific site; other neighborhoods may experience different concentrations that are not captured here. Nevertheless, the data are current as of early February 2026 and provide a snapshot of the six key air‑quality components for the area at that moment.
