Air quality today
The air quality in Thionville today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 3.0 and a PM10 reference value of 3.1, based on four valid observations collected via OpenAQ.
Overall conditions meet the criteria for a Good rating according to the available data. 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 Thionville air‑quality dataset contains measurements for six pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). The data come from ten individual rows recorded at three monitoring stations across the city, giving a modest spatial coverage that captures conditions in the centre and the Garche neighbourhood.
Most of the recent observations were uploaded on 2026‑02‑10, with NO₂, O₃ and PM₁₀ refreshed within the last few days (15:00 UTC for NO₂ and O₃, 14:00 UTC for PM₁₀). The highest recorded NO₂ value in this snapshot is 16.4 µg/m³ at Thionville‑Centre, while the median sits near 5.9 µg/m³ and values as low as 4.4 µg/m³ are also present. Ozone shows a tighter band: measurements range from 49.4 to 54.2 µg/m³, with a median of 51.8 µg/m³ and the 10th‑percentile at about 49.9 µg/m³. PM₁₀ values are low overall, spanning 3.1–9.3 µg/m³; the median is 6.2 µg/m³ and half of the readings fall below roughly 5 µg/m³.
In contrast, NO and SO₂ have only a single recent entry each, both dated earlier than the main batch – NO was last recorded on 2024‑03‑11 (3.1 µg/m³) and SO₂ on 2019‑08‑27 (5.0 µg/m³). PM₂.₅ also appears once, measured at 3.0 µg/m³ on 2026‑02‑10. This uneven temporal coverage means that while the city’s current NO₂, O₃ and PM₁₀ levels are well represented, information for NO, PM₂.5 and especially SO₂ is sparse and dated, so conditions for those pollutants may differ from what the latest rows show.
