Air quality today

The air quality in Cartignies today is classified as Good. The primary pollutant measured is PM2.5, with a reference concentration of 2.9 µg/m³, while the accompanying PM10 level stands at 4.0 µg/m³ based on four valid observations.

Data are shown via OpenAQ and reflect the current monitoring results for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Cartignies draws on seven data rows from two monitoring stations, covering five measured pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). The most recent observations are all from 2026‑02‑10 15:00 UTC for O3, NO2, PM10 and PM2.5, giving a fresh snapshot of conditions on that date. NO is the exception, with its only entry dated 2024‑03‑11 08:00 UTC, so information on this gas is older by almost two years.

Across the recent data set, ozone values range from a low of 42.38 µg/m³ to a high of 69.7 µg/m³, with a median around 56 µg/m³ and the central 80 % falling between roughly 45 and 67 µg/m³. Particulate matter shows a much tighter spread: PM10 varies between 4.0 and 18.03 µg/m³ (median 11.02 µg/m³), while PM2.5 is recorded at a single value of 2.9 µg/m³, indicating only one recent measurement for the finer fraction. Nitrogen oxides are also limited to single points—NO at 1.2 µg/m³ and NO2 at 4.6 µg/m³—both representing the sole entries for their respective gases.

The dataset contains four rows that are classified as “old” (more than three days old) and three rows with unknown freshness, meaning a notable portion of the historical record is not up‑to‑date. Consequently, while the latest 2026‑02‑10 readings give a clear picture for most pollutants, gaps remain for NO and for any periods beyond the most recent snapshot; conditions in Cartignies can therefore differ across locations and times that are not captured by the current data.

Data notes

The data shown for Cartignies reflects four valid measurements and is updated within 3 days, with the latest values recorded at 2026‑02‑10T15:00:00+00:00. These figures provide a recent snapshot of ambient air quality across the city, but conditions can differ by neighbourhood and change rapidly over short periods. Consequently, the displayed values represent an approximate overview rather than precise real‑time readings for every location.
