Unhealthy air today for Khan Prek Pnov, Phnom Penh, Cambodia
This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Khan Prek Pnov is classified as Unhealthy today. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 77.84 µg/m³ based on five valid observations reported through OpenAQ.
Data for other pollutants are not available, and the measurement count confirms that five separate readings contributed to this assessment. 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 air‑quality feed for Khan Prek Pnov currently draws from a single monitoring location – Kok Roka – which supplies data on five measured variables: PM1 at 54.88 µg/m³, PM2.5 at 77.84 µg/m³, relative humidity at 59.42 %, temperature at 26.27 °C and particle count (UM003) at 4 179.09 particles/cm³. All of these readings were last updated on 2026‑02‑10 19:00 UTC, meaning the dataset is fresh within the past three days for every pollutant.
Because only one station contributes rows, there is no spatial spread across Khan Prek Pnov; any variation in air quality that might exist elsewhere in the city is not captured here. The values reported are identical for minimum, median and maximum, indicating a single snapshot rather than a range of observations over time. Consequently, the dataset cannot show day‑to‑day fluctuations or longer‑term trends.
Despite the limited coverage, the data does give a clear picture of current conditions at Kok Roka: particulate matter concentrations (both PM1 and PM2.5) are recorded to two decimal places, humidity is measured precisely to three decimals, temperature is logged with six‑digit precision, and the particle counter provides an exact count per cubic centimetre. All five pollutants share the same timestamp, confirming that the sensor suite was refreshed together at the most recent update. Users should keep in mind that because only one location reports, conditions elsewhere in Khan Prek Pnov may differ from these figures.

Data notes
The data shown for Khan Prek Pnov is based on five valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T19:00:00+00:00 (updated within 3 days). This snapshot reflects conditions captured at that time, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
