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 Kwai Tsing District data set contains a single monitoring location – the Kwai Chung station – and reports five pollutants: nitrogen dioxide, ozone, particulate matter 10, particulate matter 2.5 and sulphur dioxide. All five measurements were recorded at the same moment on 2026‑02‑10 22:00 UTC, so the freshest timestamp for each pollutant is that date and time. Because there is only one row in the dataset, coverage across the district is limited to this point source rather than a network of stations.
Across the five pollutants the recorded values are identical at their minimum, median and maximum, indicating no observed variation within the single‑station record. Nitrogen dioxide registers 47.8 µg/m³, ozone 39.0 µg/m³, PM10 14.0 µg/m³, PM2.5 9.6 µg/m³ and sulphur dioxide 0.7 µg/m³. The narrow spread – each pollutant’s 10th and 90th percentiles match the single reported value – reflects that only one measurement is available rather than a distribution over time or space.
Since every entry was updated within three days of collection, the data are recent but limited in scope. Users should keep in mind that conditions can differ across other parts of Kwai Tsing and at other times, as this snapshot does not capture temporal changes or spatial variability beyond the lone Kwai Chung location.

Data notes
The data shown for Kwai Tsing District is based on five valid measurements and was refreshed recently, having been updated within three days (last update: 2026‑02‑10T22:00:00+00:00). While these figures give a reliable snapshot of current conditions, air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in this summary.
