Air quality today
The air quality in Zhudong is currently rated as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 11.0 µg/m³ and a PM10 level of 16.0 µg/m³, based on six valid observations reported through OpenAQ.
These values reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Zhudong air‑quality dataset contains measurements for six pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃), particulate matter up to 10 µm (PM10), fine particulate matter up to 2.5 µm (PM2.5, written as PM25) and sulfur dioxide (SO₂). These values come from a total of twelve individual rows collected at two monitoring stations in the region, all recorded on the same recent timestamp of 2026‑02‑10 23:00 UTC, which falls within the “updated within 7 days” freshness window.
Across the dataset the observed concentrations show modest variability. CO ranges from a low of 0.25 ppm to a high of 0.36 ppm with a median of about 0.31 ppm; NO₂ spans 0.0047‑0.012 ppm (median ≈0.008 ppm); O₃ varies between 0.009 and 0.0537 ppm (median ≈0.031 ppm). Particulate matter shows a tighter spread: PM10 values lie between 16.0 and 25.0 µg/m³ (median ≈20.5 µg/m³) while PM2.5 stays within 11.0‑12.0 µg/m³ (median ≈11.5 µg/m³). SO₂ is the lowest‑level gas, recorded from 0.0014 to 0.0022 ppm with a median near 0.0018 ppm.
The data set is uniformly recent – every pollutant entry lists the same last‑updated time, indicating no older or unknown timestamps. However, only two stations contribute all twelve rows, so spatial coverage within Zhudong is limited to those monitoring points. Consequently, while the numbers give a clear snapshot of current concentrations, they may not capture finer local variations that could exist across different neighborhoods or micro‑environments in the city.

Data notes
The data shown 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 current view of air quality in Zhudong, but conditions can differ across neighborhoods and change throughout the day, so local variations may exist.
