Air quality today

The air quality in Dongshan is currently rated as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 9.0 µg/m³ and a PM10 level of 20.0 µg/m³, based on six valid observations.

Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Dongshan includes six measured pollutants—carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO₂). All of these values come from a single monitoring station, so the city’s air‑quality picture is based on six rows of data rather than a network of sites.

Each pollutant has one recorded value that also serves as its minimum, median and maximum for the period covered. CO registers at 0.26 ppm, NO₂ at 0.007 ppm, O₃ at 0.015 ppm, PM10 at 20.0 µg/m³, PM2.5 at 9.0 µg/m³ and SO₂ at 0.0006 ppm. Because there is no spread in the numbers, the dataset does not show any range or variability for any of the pollutants; the typical (median) reading is identical to the sole measurement available.

All six observations were last updated on 2026‑02‑10 at 23:00 UTC and are flagged as “Updated within 7 days,” indicating that the most recent data are relatively fresh. However, with only one station contributing, the coverage is limited and may not capture spatial differences across Dongshan. Consequently, while the current snapshot provides concrete values for each pollutant, it cannot reflect how conditions might differ in other parts of the city or change over shorter time intervals.

Data notes

The data shown for Dongshan reflects six valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 23:00 UTC; it is considered “Updated within 3 days.” This snapshot provides a brief view of current conditions, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
