Air quality today
The air quality in Izumiotsu is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 21.0 µg/m³ based on four valid observations reported through OpenAQ. No PM10 reference value is available for this assessment. 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 Izumiotsu contains measurements for four key pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All of the data come from a single monitoring site located at 泉大津市東雲町９－１２, so the city’s air quality picture is based on four rows of observations rather than a network of stations. Each pollutant has only one recorded value, and that value is identical for its minimum, median and maximum, indicating no observed variation within the sampled period.
The most recent update for every parameter was recorded on 2026-02-10 at 22:00 UTC, which falls well inside the “updated within three days” freshness window. Because all four pollutants share this timestamp, the dataset is uniformly current across the board. The measured concentrations are very low for the gases – NO sits at 0.008 ppm, NO₂ at 0.028 ppm and NOX at 0.036 ppm – while PM2.5 registers a single reading of 21.0 µg/m³. With only one location feeding data, there is no spread to describe; the reported figures represent both the lowest and highest values captured.
Given that the coverage consists of a solitary site, the numbers reflect conditions at that specific address rather than city‑wide averages. While the timestamps are fresh, the lack of multiple stations means spatial differences across Izumiotsu cannot be assessed from this dataset alone. Users should keep in mind that air quality can change throughout the city and over time, even though the current snapshot is up‑to‑date for the monitored point.
