Air quality today
The air quality in Izumi is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 14.0 µg/m³ based on five valid observations collected via OpenAQ. This reflects the latest available data for the city.

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 Izumi contains measurements for four pollutants – PM2.5, NO, NO₂ and NOX – collected from a total of five data rows representing two monitoring stations. All entries were last refreshed within the past three days, with the most recent timestamp recorded at 2026-02-10 22:00 UTC for each pollutant. This means that the available information reflects conditions as they stood just a few days ago and does not include any older or unknown‑date records.
PM2.5 values are reported in micrograms per cubic metre and range from a minimum of 5.0 to a maximum of 14.0 µg/m³, with a median of 9.5 µg/m³. The ten‑percentile sits at 5.9 µg/m³ and the ninety‑percentile at 13.1 µg/m³, indicating that most recent readings cluster around the middle of this span. Nitrogen oxides are measured in parts per million; each of the three nitrogen species (NO, NO₂ and NOX) has a single recorded value – 0.001 ppm for NO, 0.018 ppm for NO₂ and 0.019 ppm for NOX – all coming from the same station location (和泉市緑ケ丘３－４－１). Because only one row exists for each nitrogen compound, there is no observed spread or variability in those measurements.
Overall, the coverage is uneven: while PM2.5 benefits from two rows that capture a modest range of concentrations, the nitrogen‑oxide metrics rely on a single observation per pollutant, limiting insight into spatial or temporal variation. The data are current but sparse, so conditions across different parts of Izumi may differ from what these few recent points show.

Data notes
The current dataset for Izumi includes five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is therefore considered “Updated within 3 days.” This snapshot reflects conditions at the time of sampling, but air quality can differ across neighborhoods and change throughout the day, so values may vary locally.
