Air quality today
The air quality in Flémalle today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 0.0 and a PM10 reference value of 0.271, based on four valid observations recorded by OpenAQ.
Overall conditions meet the criteria for a Good rating according to the current 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 Flémalle air‑quality record draws from a single monitoring site (48R236 – FLEMALLE), so the dataset contains one row of observations for each pollutant. All four measured gases and particles are represented: carbon monoxide, nitrogen dioxide, PM10 and PM2.5. The most recent reading for every compound was logged on 2026‑02‑10 at 18:00 UTC, meaning the data are fresh within the last three days.
Carbon monoxide shows a uniform value of 140.0 µg/m³ across its minimum, median and maximum, indicating no variation in the single sample available. Nitrogen dioxide is similarly consistent, with every statistic equal to 5.5 µg/m³. Particulate matter behaves differently: PM10 registers a low concentration of 0.271 µg/m³, again without any spread, while PM2.5 records a value of zero across the board. Because only one station contributes, there is no range or distribution to describe trends; each pollutant’s statistics collapse to a single point.
With just one monitoring location, spatial coverage for Flémalle is limited, and the dataset does not capture differences that might exist across neighborhoods or over time. The timestamps confirm that all four pollutants were last updated at the same moment, so there are no older or unknown entries in this snapshot. Consequently, while the figures give a clear picture of the current measured levels at the 48R236 site, they do not reflect broader city‑wide conditions, which can vary by place and time.

Data notes
The data shown for Flémalle are based on four valid measurements and were updated within three days, with the latest refresh recorded at 2026‑02‑10 18:00 UTC. This snapshot reflects conditions at the time of sampling; air quality can vary across different neighbourhoods and moments throughout the city, so values may differ from what you experience locally.
