Air quality today

The air quality in Akashi is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 27.0 µg/m³, based on twelve valid observations collected through OpenAQ.

Data indicate that the overall condition falls within the moderate range, with fine particulate matter being the dominant factor measured today. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Akashi air‑quality dataset currently includes six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). The data come from twelve individual rows collected at three monitoring sites across the city, each row representing a single measurement for one pollutant at a specific location. All of the latest readings were recorded on 2026‑02‑10 at 22:00 UTC, so the information is fresh and falls within the “updated within three days” window used by the source.

PM2.5 values are reported in micrograms per cubic metre, with a minimum, median and maximum all equal to 27.0 µg/m³ at the site on 二見町東二見４５７の１. This indicates that, for the period covered, the particulate concentration was stable across the three recorded rows. Nitrogen‑related gases show slightly more variation: NO is consistently measured at 0.001 ppm, while NO₂ ranges from 0.015 to 0.017 ppm (median 0.016 ppm) and NOX spans 0.016–0.018 ppm (median 0.017 ppm), all taken at the same 二見町 location. Sulfur dioxide registers a uniform zero reading (0.0 ppm) across its two rows, also from 二見町. Carbon monoxide is captured at a single site in 林崎町１丁目８の１０ with a value of 0.4 ppm.

Because each pollutant is represented by only one to three recent rows, the dataset provides a snapshot rather than a detailed time series. The coverage is uneven: PM2.5, NO, NO₂ and NOX have three recent entries each, whereas SO₂ has two and CO just one. While the timestamps are all current, the limited number of observations means that conditions can differ across neighborhoods or change after the last update. Users should keep in mind that these figures reflect a narrow sampling window and specific monitoring points within Akashi.

Data notes

The data shown reflect twelve valid measurements and were refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; the dataset is considered “Updated within 3 days.” This snapshot provides a momentary view of Akashi’s air quality, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
