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 OpenAQ feed for Molenbeek‑Saint‑Jean includes data on carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), sulphur dioxide (SO₂), particulate matter of three size fractions (PM₁, PM₂·₅ and PM₁₀), relative humidity and temperature. The dataset contains 36 individual rows drawn from three monitoring stations, so each pollutant is represented by a modest number of observations rather than a dense network.

Most of the pollutants have been recorded very recently: CO, NO₂, O₃, SO₂, PM₁₀ and PM₂·₅ all show a last‑updated timestamp of 2026‑02‑10 18:00 UTC, meaning the newest values are less than two days old. Their median concentrations fall within narrow bands – for example, CO hovers around 265 µg/m³ (range 245–295), NO₂ stays at 21.5 µg/m³ (range 21.5–31), O₃ averages 46 µg/m³ (range 25.5–47) and SO₂ is centred on 3.75 µg/m³ (range 2.5–3.75). Particulate matter shows a broader spread: PM₁₀ ranges from about 5.6 to 15 µg/m³ with a median of 12.3, while PM₂·₅ varies between 1.9 and 12.1 µg/m³ and has a median near 10.6.

In contrast, the measurements for PM₁ and relative humidity are older, last refreshed on 2024‑08‑27 13:00 UTC. Their values are very stable – PM₁ sits at roughly 7.71 µg/m³ and humidity around 29.7 % – but because they have not been updated for more than a year they provide only a historical snapshot rather than current conditions. Overall, the dataset offers fresh information for most key pollutants while showing uneven temporal coverage across all measured variables; consequently, city‑wide air quality can still differ by location and time beyond what these limited rows capture.
