Air quality today
The air quality in Ikoma is currently rated as Good. The main pollutant identified is PM2.5, with a measured concentration of 7.0 µg/m³ based on five valid observations reported through OpenAQ.
These readings indicate that the particulate matter levels are within the reference range for this category. 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 Ikoma contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring location at 生駒市山崎町４－１０, so the city’s coverage in this snapshot is limited to one site but includes all five common air‑quality metrics.
The most recent readings were recorded on 2026-02-10 22:00 UTC for every pollutant, which falls within the “updated within three days” freshness window. Because each pollutant has only one row of data, there is no variation over time or across stations: the minimum, median and maximum are identical for each metric. NO registers at 0.003 ppm, NO₂ at 0.016 ppm, NOX at 0.019 ppm, PM2.5 at 7.0 µg/m³ and SO₂ is measured as 0.0 ppm.
These numbers illustrate a very narrow data spread – the recorded values are single points rather than ranges, reflecting the limited temporal depth of the current dataset. The presence of SO₂ at zero suggests either non‑detectable levels or that the sensor did not register any concentration at the time of measurement. Since only one monitoring point contributes to all five pollutants, conditions elsewhere in Ikoma may differ, and the snapshot does not capture spatial variability across the city.
