Air quality today
The air quality in Kaizuka is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 19.0 µg/m³ based on four valid observations reported through OpenAQ. No PM10 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 Kaizuka air‑quality dataset contains four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total oxidised nitrogen (NOX) and fine particulate matter (PM2.5). All four readings come from a single monitoring location at 貝塚市鳥羽１２２－１, so the city’s coverage in this set is limited to one station but includes a full suite of common urban pollutants.
Each pollutant has only one recorded value, giving a total of four rows of data. The most recent update for every measurement was on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness window, indicating that the information is current as of the last few days. Because there is only one observation per pollutant, the statistical spread is zero – the minimum, median and maximum are identical for each substance. NO registers at 0.002 ppm, NO₂ at 0.024 ppm, NOX at 0.026 ppm and PM2.5 at 19.0 µg/m³.
With a single monitoring point, the dataset cannot capture spatial variations across Kaizuka, and the lack of multiple rows means there is no temporal range to assess changes over time. Nonetheless, the data provide an up‑to‑date snapshot of the four key pollutants at that location, showing consistently low nitrogen oxide concentrations in parts per million and a PM2.5 concentration of 19 µg/m³ on the day recorded. Users should keep in mind that conditions elsewhere in the city may differ from this point source.

Data notes
The current dataset for Kaizuka includes four valid measurements and was refreshed recently, updated within 3 days (last update: 2026‑02‑10T22:00:00+00:00). These values represent a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
