Air quality today
The air quality in Bangsan‑myeon is currently classified as Moderate. The primary pollutant identified for today is PM10, the coarser particulate matter.
Measurements from five valid monitoring stations show a PM10 concentration of 61.0 µg/m³. This reflects the latest data available through OpenAQ. 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
Bangsan‑myeon’s OpenAQ feed contains data for six common air‑quality metrics: carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃, written as O3), particulate matter up to 10 µm (PM10), fine particulate matter up to 2.5 µm (PM2.5, written as PM25) and sulfur dioxide (SO₂). All six pollutants are reported from a single monitoring location in the district, so the dataset represents one station row for each pollutant.
The most recent observation for every pollutant was recorded on 2026‑02‑10 at 17:00 UTC, meaning the data are all fresh within the last seven days. For CO the value is 0.61 ppm; NO₂ registers 0.0052 ppm; O₃ shows 0.0201 ppm; PM10 measures 61.0 µg/m³; PM2.5 reports an extreme placeholder of 9999.0 µg/m³, and SO₂ is at 0.0011 ppm. Because each pollutant has only one recorded value, the minimum, median, maximum, 10th percentile and 90th percentile are identical for every metric.
The dataset therefore offers a complete but very limited snapshot: there is no spread of values over time or across multiple sites, so any assessment of variability or trends within Bangsan‑myeon cannot be derived from these numbers alone. The unusually high PM2.5 figure (9999.0 µg/m³) suggests either a sensor error or a placeholder for missing data rather than a realistic concentration. Overall, the coverage is narrow—six pollutants from one location with a single recent reading—so while the information is up‑to‑date, it captures only a momentary condition and may not reflect broader spatial or temporal patterns across the city.

Data notes
The data shown for Bangsan‑myeon is based on five valid measurements and was refreshed recently, having been updated within three days (last update: 2026‑02‑10 17:00 UTC). While this snapshot reflects current conditions across the monitoring network, air quality can differ by specific location and time of day within the city, so values may vary locally.
